Cardiac myopathy is a heart-related disorder. many types are there in cardiomyopathy .4 types of CMP is hypertrophic CMP, dilated CMP, restrictive CMP, stress CMP. causes of this are node related problem,ischemic condion of the heart .symptoms to this is chest pain breathlessness, edema like cardiacfailure will happen at last . manage mesvn t like betablockers , ace inhibitors doamine .dobutamine, and diuretics should be given to the patient .surgical manage meant is septal ablation, and heart transplantation should be given to the patient
Cardiomyopathy is a group of disease that affect the heart muscle. Early on there may be few or no symptoms. As the disease worsens, shortness of breath, feeling tired, and swelling of legs may occur, due to the onset of heart failure. An irregular heart beat and fainting may occur.
Cardiomyopathy is a disease of the heart muscles that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure.
According to the structural and functional abnormalities of the heart muscle
Dilated cardiomyopathy
Hypertrophic cardiomyopathy
Restrictive cardiomyopathy
Arrhythmogenic right ventricular cardiomyopathy
Unclassified cardiomyopathy
this article discusses about coronary artery disease, its symptoms, presentations, risk factors, pathophysiology in short and primary prevention. this article is intended to present to a group of physicians in various disciplines other than cardiology.
Restrictive cardiomyopathy
Cardiac diseases due to intrinsic myocardial dysfunction.
Primary & secondary.
The three major types are
Dilated cardiomyopathy
Hypertrophic cardiomyopathy
Restrictive cardiomyopathy
Restrictive Cardiomyopathy is Characterized by a primary decrease in ventricular compliance, resulting in impaired ventricular filling during diastole.
Diastolic dysfunction ; but systolic function is unaffected.
May be confused with constrictive pericarditis or HCM.
Idiopathic or associated with systemic diseases.

An acquired or inherited disease of the heart muscle which makes it difficult for the heart to pump blood to other parts of the body. Can be dangerous or life threatening if untreated
Myocardial infarction is the medical name of a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men.
Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents, and bypass surgery.

Enumerate the types of cardiac apical impulse with example
Normal apical impulse:
The normal apical impulse is described as a brief, tapping, and low-pitched sensation felt at the 5th intercostal space in the midclavicular line. It has a duration of less than 0.16 seconds and an amplitude of less than 2.5 cm. This is considered a normal finding and represents the left ventricular impulse.
Displaced apical impulse:
A displaced apical impulse refers to a sensation felt at a location other than the normal 5th intercostal space in the midclavicular line. This finding can be indicative of left ventricular hypertrophy, left atrial enlargement, or pericardial effusion. For example, in left ventricular hypertrophy, the apical impulse is felt at a more lateral location in the 6th or 7th intercostal space, while in pericardial effusion, the apical impulse may be difficult to palpate due to the accumulation of fluid around the heart.
Hyperdynamic impulse: A forceful and sustained apical impulse that is typically seen in conditions such as hyperthyroidism or anemia.
Heaving impulse: A slow-rising, sustained apical impulse that may be seen in conditions such as aortic stenosis or hypertrophic cardiomyopathy.
Tapping impulse: A sharp, brief apical impulse that is felt during the first half of systole and may be seen in conditions such as mitral stenosis or aortic regurgitation.
Displaced impulse: An apical impulse that is felt in a location other than the normal fifth intercostal space, midclavicular line. This may be seen in conditions such as left ventricular hypertrophy or cardiac tamponade.
Diffuse impulse: An apical impulse that is felt over a wider area than normal, indicating enlargement of the heart. This may be seen in conditions such as dilated cardiomyopathy or chronic severe mitral regurgitation.
What are the causes of shifted cardiac impulse ?
Shifted cardiac impulse or displaced cardiac impulse is a clinical finding in which the cardiac apex is located outside the normal location. It may occur due to various causes, including:
Left ventricular hypertrophy: A thickening of the left ventricle of the heart, commonly seen in conditions like hypertension and aortic stenosis.
Dilated cardiomyopathy: A condition in which the heart becomes enlarged and weakened, leading to heart failure.
Constrictive pericarditis: Inflammation and scarring of the pericardium (outer layer of the heart) leading to restricted movement of the heart.
Tension pneumothorax: A condition in which air accumulates in the pleural cavity and compresses the heart leading to a shift in its position.
Large pleural effusion: An accumulation of fluid in the pleural cavity which can compress the heart leading to its displacement.
Massive ascites: Accumulation of fluid in the abdomen which can push the diaphragm upwards leading to t
In heart valve disease, one or more of the valves in your heart doesn't work properly.
Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don't open or close properly. This can cause the blood flow through your heart to your body to be disrupted.
Your heart valve disease treatment depends on the heart valve affected and the type and severity of the valve disease. Sometimes heart valve disease requires surgery to repair or replace the heart valve.Your heart has four valves that keep blood flowing in the correct direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (leaflets or cusps) that open and close once during each heartbeat. Sometimes, the valves don't open or close properly, disrupting the blood flow through your heart to your body.
Heart valve disease may be present at birth (congenital). It can also occur in adults due to many causes and conditions, such as infections and other heart conditions.
Heart valve problems may include:
Regurgitation. In this condition, the valve flaps don't close properly, causing blood to leak backward in your heart. This commonly occurs due to valve flaps bulging back, a condition called prolapse.
Stenosis. In valve stenosis, the valve flaps become thick or stiff, and they may fuse together. This results in a narrowed valve opening and reduced blood flow through the valve.
Atresia. In this condition, the valve isn't formed, and a solid sheet of tissue blocks the blood flow between the heart chambers.Several factors can increase your risk of heart valve disease, including:
Older age
History of certain infections that can affect the heart
History of certain forms of heart disease or heart attack
High blood pressure, high cholesterol, diabetes and other heart disease risk factors
Heart conditions present at birth (congenital heart disease)Heart valve disease can cause many complications, including:
Heart failure
Stroke
Blood clots
Heart rhythm abnormalities
Death
Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly.
Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms.
Heart arrhythmia treatment can often control or eliminate fast, slow or irregular heartbeats. In addition, because troublesome heart arrhythmias are often made worse — or are even caused — by a weak or damaged heart, you may be able to reduce your arrhythmia risk by adopting a heart-healthy lifestyle.Arrhythmias may cause you to feel premature heartbeats, or you may feel that your heart is racing or beating too slowly. Other signs and symptoms may be related to your heart not pumping effectively due to the fast or slow heartbeat. These include shortness of breath, weakness, dizziness, lightheadedness, fainting or near fainting, and chest pain or discomfort. Seek urgent medical care if you suddenly or frequently experience any of these signs and symptoms at a time when you wouldn't expect to feel them.Ventricular fibrillation is one type of arrhythmia that can be deadly. It occurs when the heart beats with rapid, erratic electrical impulses. This causes the lower chambers in your heart (ventricles) to quiver uselessly instead of pumping blood. Without an effective heartbeat, blood pressure plummets, cutting off blood supply to your vital organs.f slow heartbeats (bradycardias) don't have a cause that can be corrected, doctors often treat them with a pacemaker because there aren't any medications that can reliably speed up the heart.
A pacemaker is a small device that's usually implanted near your collarbone. One or more electrode-tipped wires run from the pacemaker through your blood vessels to your inner heart. If your heart rate is too slow or if it stops, the pacemaker sends out electrical impulses that stimulate your heart to beat at a steady rate.
The terms leukopenia and neutropenia are often used interchangeably. However, they refer to slightly different conditions. Leukopenia is an umbrella term that refers to a reducation in any of the white blood cell types.
Neutropenia is a type of leukopenia but refers specifically to a decrease in neutrophils, the most common type of white blood cell. A person’s neutrophil count is an important indicator of their infection risk.
In disseminated intravascular coagulation, abnormal clumps of thickened blood (clots) form inside blood vessels. These abnormal clots use up the blood's clotting factors, which can lead to massive bleeding in other places. Causes include inflammation, infection and cancer.
Symptoms include blood clots and bleeding, possibly from many sites in the body.
The goal is to treat the underlying cause and provide supportive care through intravenous fluids and blood transfusions.
Leukocyte is another name for white blood cell (WBC). These are the cells in your blood that help your body fight infections and some diseases.
When the number of white cells in your blood is higher than normal, it’s called leukocytosis. This usually happens because you’re sick, but sometimes it’s just a sign that your body is stressed.is a condition that affects all types of white blood cells. Other illnesses, such as neutrophilia, lymphocytosis, and granulocytosis, target specific types of white blood cells. Normal white blood cell counts are 4,300-10,800 white blood cells per microliter. Leukocyte or white blood cell levels are considered elevated when they are between 15,000-20,000 per microliter. The increased number of leukocytes can occur abnormally as a result of an infection.An abnormally large number of leukocytes, as observed in acute infections, inflammation, hemorrhage, and other conditions. A white blood cell count of 10,000/mm3 (or more) usually indicates leukocytosis Most examples of leukocytosis represent a disproportionate increase in the number of cells in the neutrophilic series, and the term is frequently used synonymously with the designation neutrophilia. Leukocytosis of 15,000-25,000/mm3 is frequently observed in various pathologic conditions, and values as high as 40,000 are not unusual; occasionally, as in some examples of leukemoid reactions, white blood cell counts may range up to 100,000/mm3.Leukocytosis is usually a response to an infection or inflammation, so it’s not a cause for alarm. However, it can be caused by serious diseases such as leukemia and other cancers, so it’s important that your doctor diagnose the cause of an increased WBC when it’s found. Leukocytosis associated with pregnancy or in response to exercise is normal and nothing to worry about.
Leukemia is a cancer of blood-forming tissues, including bone marrow. Many types exist such as acute lymphoblastic leukemia, acute myeloid leukemia, and chronic lymphocytic leukaemia. Many patients with slow-growing types of leukaemia don't have symptoms. Rapidly growing types of leukaemia may cause symptoms that include fatigue, weight loss, frequent infections, and easy bleeding or bruising.Treatment is highly variable. For slow-growing leukemias, treatment may include monitoring. For aggressive leukemias, treatment includes chemotherapy that's sometimes followed by radiation and stem-cell transplant.
Hemophilia is not one disease but rather one of a group of inherited bleeding disorders that cause abnormal or exaggerated bleeding and poor blood clotting. The term is most commonly used to refer to two specific conditions known as hemophilia A and hemophilia BHemophilia is an inherited genetic condition. This condition isn’t curable, but it can be treated to minimize symptoms and prevent future health complications.
In extremely rare cases, hemophilia can develop after birth. This is called “acquired hemophilia.” This is the case in people whose immune system forms antibodies that attack factors VIII or IX. Hemophilia A is caused by a mutation in the gene for factor VIII, so there is deficiency of this clotting factor. Hemophilia B (also called Christmas disease) results from a deficiency of factor IX due to a mutation in the corresponding gene.
A condition referred to as hemophilia C involves a deficiency of clotting factor XI. This condition is much rarer than hemophilia A and B and typically leads to mild symptoms. It is also not inherited in an X-linked manner and affects persons of both sexes.
Lymphangitis is inflammation of lymphatic channels due to infectious or noninfectious causes. Potential pathogens include bacteria, mycobacteria, viruses, fungi, and parasites. Lymphangitis most commonly develops after cutaneous inoculation of microorganisms into the lymphatic vessels through a skin wound or a distal infection complication.
Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer. Your lymph nodes, also called lymph glands, play a vital role in your body's ability to fight off infections. They function as filters, trapping viruses, bacteria and other causes of illnesses before they can infect other parts of your body. Common areas where you might notice swollen lymph nodes include your neck, under your chin, in your armpits and in your groin.
In some cases, the passage of time .Hard, swollen or tender lymph nodes
Itchy skin, Lump, or mass that can be felt beneath the skin, Rash
Redness, warmth or selling immune system disorders
Lupus — a chronic inflammatory disease that targets your joints, skin, kidneys, blood cells, heart and lungs
Rheumatoid arthritis — a chronic inflammatory disease targeting the tissue that lines your joints (synovium)
Cancers
Lymphoma — cancer that originates in your lymphatic system
Leukemia — cancer of your body's blood-forming tissue, including your bone marrow and lymphatic system
Other cancers that have spread (metastasized) to lymph nodes
Lymphoma is a cancer of the lymphatic system, which is part of the body's germ-fighting network.
The lymphatic system includes the lymph nodes (lymph glands), spleen, thymus gland and bone marrow. Lymphoma can affect all those areas as well as other organs throughout the body.Being older, male, or Caucasian
Having any of the following conditions:
An inherited immune system disorder
An autoimmune disease, Use of immunosuppressant drugs following an organ transplant
High levels of exposure to certain pesticides have been found in some observational studies to slightly increase the risk of NHL in agricultural workers. The risk from low-level and/or periodic exposure to these substances is not certain.
Exposure to radiation THESEare the cause.symptoms. These can include:
night sweats
unintentional weight loss
a high temperature (fever)
a persistent cough or feeling of breathlessness
persistent itching of the skin all over the body, treat meant include like chemotherapy, radiation therapy, bone marrow transplantation, etc
An aneurysm is an enlargement of the artery. it is divided into 3type according to action, more pathology, etc. the treatment of this is commonly surgery some of the procedures also help full for the aneurysm like shutting procedure. the prevention n of this is avoid smoking, exercise...
Raynauds disease is Raynaud's (ray-NOSE) disease that causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress. In Raynaud's disease, smaller arteries that supply blood to your skin become narrow, limiting blood flow to affected areas (vasospasm).This condition causes “attacks” that limit blood supply to fingers and toes, which may get pale, cold and numb. As blood returns, they may start to tingle and hurt. Except in rare cases, it’s typically not serious. There’s no cure, but there are changes you can make to your routine, dress, and diet that can help you manage symptoms. Episodes are typically triggered by cold or emotional stress. The primary treatment is avoiding the cold. Other measures include the discontinuation of nicotine or stimulant use. vaso dilator is effective .statinis effective for this condition
Cellulitis is a bacterial infection of the deep dermis and subcutaneous tissue. It is most commonly caused by S. pyogenes and S. aureus.5 Bacteria may gain access to the dermis via a break in the skin barrier in healthy adults, whereas the hematogenous route is more common in immunocompromised patients.
The affected skin is usually erythematous, swollen, painful, and warm to the touch. Severe cellulitis can be complicated by bullae, pustules, or necrotic tissue. Damage to lymphatic vessels can lead to recurrent episodes of cellulitis.6 In areas of the world endemic for lymphatic filariasis, it is important to rule out this disease in cases of recurrent bouts of lower-extremity cellulitis and lymphangitis.
high blood pressure (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. A blood pressure reading is given in millimeters of mercury (mm Hg). It has two numbers. The top number (systolic pressure). The first, or upper, number measures the pressure in your arteries when your heartbeats.
Bottom number (diastolic pressure). The second, or lower, number measures the pressure in your arteries between beats.For most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure, called primary (essential) hypertension, tends to develop gradually over many yearsSome people have high blood pressure caused by an underlying condition. This type of high blood pressure, called secondary hypertension, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension, including: Obstructive sleep apnea
Kidney disease
Adrenal gland tumors
Thyroid problems
Certain defects you're born with (congenital) in blood vessels
Certain medications, such as birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs
Illegal drugs, such as cocaine and amphetamines. The risk of high blood pressure increases as you age. Until about age 64, high blood pressure is more common in men. Women are more likely to develop high blood pressure after age 65.
Race. High blood pressure is particularly common among people of African heritage, often developing at an earlier age than it does in whites. Serious complications, such as stroke, heart attack and kidney failure, also are more common in people of African heritage.Weakened and narrowed blood vessels in your kidneys. This can prevent these organs from functioning normally.
Thickened, narrowed, or torn blood vessels in the eyes. This can result in vision loss.
Varicose veins are dilated, often palpable subcutaneous veins with reversed blood flow. They are most commonly found in the legs. Estimates of the prevalence of varicose veins vary. Visible varicose veins in the lower limbs are estimated to affect at least a third of the population. Varicose veins are swollen, twisted veins that you can see just under the skin. They usually occur in the legs, but also can form in other parts of the body. Hemorrhoids are a type of varicose vein.
Your veins have one-way valves that help keep blood flowing toward your heart. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose veins.
Varicose veins are very common. You are more at risk if you are older, are female, have obesity, don't exercise, or have a family history of varicose veins. They can also be more common in pregnancy. Visible Blue, Red, or Purple veins in legs. May even bulge

2. INTRODUCTION
Cardiomyopathies (CMPs) are primary disorders of myocardial structure
and function in the absence of coronary artery disease, hypertension,
valvular disease, and congenital heart disease. Knowledge of the incidence
and prevalence of CMPs may help clinicians to compare their observations
in clinical practice with expected cases per person-year and to avoid under-
reporting in clinical context. Currently, available estimates of prevalence
and incidence of CMPs are based on clinical data, collected with a wide
variability in population-source, and before the genetic testing evolved as a
standard diagnostic tool. This review focuses on the epidemiology of CMPs
in subjects aged between 18 and 55 years. A structured up-to-date
diagnostic flow-chart for CMPs diagnosis and assessment is proposed to
avoid misdiagnosis of CMPs in the young populationThe prevalence of
dilated cardiomyopathy (DCM) is approximately 1/250 (0.4%), of
hypertrophic cardiomyopathy (HCM) is approximately 1/500 (0.2%) and of
arrhythmogenic right ventricular cardiomyopathy (ARVC) is approximately
1/5,000 (0.02%)
3. DEFINITION OF CARDIO MYOPATHY
Cardiomyopathy refers to diseases of the heart muscle. In cardiomyopathy, the heart
muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is
replaced with scar tissue.
5. CARDIOMYOPATHY
Hypertrophic cardiomyopathy happens when the heart muscle enlarges and thickens without an obvious cause. Usually
the ventricles, the lower chambers of the heart, and septum (the wall that separates the left and right side of the heart)
thicken. The thickened areas create narrowing or blockages in the ventricles, making it harder for the heart to pump
blood. Hypertrophic cardiomyopathy also can cause stiffness of the ventricles, changes in the mitral valve, and cellular
changes in the heart tissue.Hypertrophic cardiomyopathy is very common and can affect people of any age. Hypertrophic
cardiomyopathy affects men and women equally, and about 1 out of every 500 people has the disease.
Other name of HCM is symmetric septal hypertrophy; idiopathic
hypertrophic subaortic stenosis, hypertrophic obstructive
cardiomyopathy
6. TYPES OF HCM
Different types of HCM are described according to where in the heart the thickened
area of muscle is. This also affects what symptoms someone might experience and
what treatment is needed.
Apical hypertrophy – the thickened area is at the bottom (apex) of the heart. This
usually reduces the volume of the ventricle.
Symmetrical hypertrophy – the thickening affects the whole of the left ventricle,
reducing its volume. This is sometimes called ‘concentric’ hypertrophy.
Asymmetrical septal hypertrophy without obstruction – the thickening affects the
heart’s septum. ‘Without obstruction’ means that the thickening doesn’t affect or
restrict the flow of blood leaving the heart.
Asymmetrical septal hypertrophy with obstruction – the thickening affects the
heart’s septum. However, unlike the type above, the thickened area causes
an obstruction that affects the flow of blood leaving the heart. When this happens,
the ventricle has to work harder to pump out blood. The mitral valve can also be
affected and is unable to close properly. This means that blood leaks back into the
atrium (called mitral regurgitation) which can cause a murmur (sound that can be
heard through a stethoscope).
7. CAUSES OF HCM
Genetics
HCM is typically an inherited condition. Defective genes can cause your
heart muscle to thicken. You have a 50 percent chance of inheriting one of
these genes if one of your parents is affected by HCM.
Hypertension
9. SIGNS AND SYMPTOMS OF HCM
• Chest pain, especially during exercise
• Fainting, especially during or just after exercise or exertion
• Heart murmur, which a doctor might detect while listening to
your heart
• Sensation of rapid, fluttering or pounding heartbeats
(palpitations)
• Shortness of breath, especially during exercise
10. MANAGEMENT OF HCM
•Beta blockers such as metoprolol (Lopressor, Toprol-XL),
propranolol (Inderal, Innopran XL) or atenolol (Tenormin)
•Calcium channel blockers such as verapamil (Verelan, Calan SR,) or
diltiazem (Cardizem, Tiazac)
•Heart rhythm drugs such as amiodarone (Pacerone) or
disopyramide (Norpace)
•Blood thinners such as warfarin (Coumadin, Jantoven), dabigatran
(Pradaxa), rivaroxaban (Xarelto) or apixaban (Eliquis) to prevent
blood clots if you have atrial fibrillation
11. SURGICAL MANAGEMENT
Septal myectomy. This open-heart surgery may be recommended if medications do not improve your symptoms. It involves
removing part of the thickened, overgrown wall (septum) between the heart chambers. Septal myectomy helps improve blood
flow out of the heart and reduces backward flow of blood through the mitral valve (mitral regurgitation).
The surgery may be done using different approaches, depending on the location of the thickened heart muscle. In one type,
called apical myectomy, surgeons remove thickened heart muscle from near the tip of the heart. Sometimes the mitral valve is
repaired at the same time.
Septal ablation. This procedure destroys the thickened heart muscle with alcohol. The alcohol is injected through a long, thin
tube (catheter) into the artery supplying blood to that area. Possible complications include disruption of the heart's electrical
system (heart block), which requires implantation of a pacemaker.
Implantable cardioverter-defibrillator (ICD). An ICD is a small device that continuously monitors your heartbeat. It's
implanted in your chest like a pacemaker. If a life-threatening arrhythmia occurs, the ICD delivers precisely calibrated
electrical shocks to restore a normal heart rhythm. ICD has been shown to help prevent sudden cardiac death, which occurs
in a small number of people with hypertrophic cardiomyopathy.
12. DILATED CARDIOMYOPATHY
Dilated cardiomyopathy develops when the ventricles enlarge and weaken. The condition
usually starts in the left ventricle and over time can affect the right ventricle. The weakened
chambers of the heart don’t pump effectively, causing the heart muscle to work harder. Over
time, the heart loses the ability to pump blood effectively. Dilated cardiomyopathy can lead
to heart failure, heart valve disease, irregular heart rate, and blood clots in the heart.
Other names OF DCM IS Congestive cardiomyopathy,
idiopathic cardiomyopathy,
primary cardiomyopath
13. CAUSES /RISK FACTOR OF DCM
It may be difficult to determine the cause of dilated cardiomyopathy. The condition often runs in families (is inherited). However,
many things can cause the left ventricle to dilate and weaken, including:
•Diabetes
•Obesity
•Heart rhythm problems (arrhythmias)
•High blood pressure (hypertension)
•Complications of late-stage pregnancy
•Excessive iron in your heart and other organs (hemochromatosis)
•Certain infections
Other possible causes of dilated cardiomyopathy include:
•Alcohol abuse
•Use of certain cancer medications
•Use of illegal drugs, such as cocaine or amphetamines
•Exposure to toxins, such as lead, mercury and cobalt
Risk factors
Risk factors for dilated cardiomyopathy include:
•Long-term high blood pressure
•Family history of dilated cardiomyopathy, heart failure or sudden cardiac arrestACTOR
•Inflammation of the heart muscle from immune system disorders, such as lupus
•Damage to the heart muscle from certain diseases, such as hemochromatosis

shortness of breath when at rest.
•Shortness of breath when lying flat
•Sudden shortness of breath that wakes you up at night
•Tiredness (fatigue)
•Less able to be active and exercise

17. MANAGEMENT O F DCM
Angiotensin converting enzyme inhibitors lisinopril (32.5–35 mg) are as
well tolerated as low doses (2.5–5 mg),
β Blockers; bisoprolol, metoprolol
Spironolactone;
Anticoagulants; warfarin.
Immunomodulation/immunosuppression; Immunosuppression is also a
rather indiscriminate weapon, as it may suppress potentially beneficial
immune responses such as neutralising antibody production in patients
with chronic viral myocarditis. New approaches to the diagnosis of chronic
myocarditis and the treatment of inflammatory cardiomyopathy should
improve this situation. There are already interesting preliminary data
suggesting that high dose immunoglobulin and immunoadsorption may
result in short term improvement in left ventricular performance in patients
with dilated and peripartum cardiomyopathy.
18. MANAGEMENT O F DCM
Partial left ventriculectomy (“Batista” procedure)
Partial left ventriculectomy is based on the hypothesis that as wall tension is related to left ventricular diameter (Laplace's
law), reducing the left ventricular size by excision of a portion of its circumference should reduce wall stress and improve
ventricular haemodynamics. In the best centres results from this intervention were initially remarkably good given the
nature of the procedure. It is clear, however, that even with careful patient selection many patients survive only with the
benefit of left ventricular assist devices and subsequent transplantation. Late sudden death is also described in a
proportion of survivors. The difficulties associated with patient selection and subsequent postoperative care suggest that,
at best, this form of treatment will be confined to a very small number of experienced centres.
Left ventricular assist devices
Left ventricular assist devices (LVADs) have recently received approval from the US Food and Drug Administration for use
in patients with end stage heart failure as a bridge to cardiac transplantation. Experience in patients with IDC suggests
that LVAD treatment can result in an apparent improvement in left ventricular function that may persist when the device is
removed. However, there are as yet no reliable markers that distinguish the minority of patients that sustain useful
recovery from the majority that deteriorate following explantation of the device. Technical advances in LVAD design now
raise the possibility of using these devices as an alternative to transplantation in patients who are not transplant
candidates. This mode of treatment is currently being evaluated in the REMATCH study, which if positive will have
substantial clinical and resource implications for centres managing advanced heart failure.
Multisite ventricular pacing
Many patients with advanced IDC have abnormal left ventricular activation that in turn results in prolonged and
incoordinate ventricular relaxation. In some patients ventricular conduction delay is also associated with prolongation of
atrioventricular conduction, resulting in a loss of atrioventricular synchrony and a predisposition to prolonged functional
mitral regurgitation. Dual chamber pacing has been advocated as a method for restoring AV synchrony and improving left
ventricular coordination in patients with severe congestive heart failure. Although initially favourable haemodynamic results
using conventional right ventricular pacing were not confirmed by later studies, there has been a more consistent
response in studies that have used biventricular pacing, the outcome depending critically on the native QRS duration and
the paced AV delay. Patients should be considered for biventricular pacing if they have QRS duration greater than 150 ms,
PR interval prolongation, and symptoms refractory to conventional medical treatment.
19. COMPLICATION OF DCM
•Heart failure. If you have dilated cardiomyopathy, your heart might not be
able to supply your body with the blood it needs to work properly, leading to
heart failure. Fluid can build up in the lungs, abdomen, legs, ankles and feet.
•Heart valve regurgitation. Enlargement of the left ventricle may make it
harder for your heart valves to close, causing a backward flow of blood and
making your heart pump less effectively.
•Heart rhythm problems. Changes in your heart's structure and changes in
pressure on your heart's chambers can lead to the development of abnormal
heart rhythms (arrhythmias).
•Sudden cardiac arrest. Dilated cardiomyopathy can cause your heart to
suddenly stop beating.
•Blood clots (emboli). Pooling of blood in the left ventricle can lead to blood
clots, which may enter the bloodstream and cut off the blood supply to vital
organs. These blood clots can cause stroke, heart attack or damage to other
organs. Arrhythmias can also cause blood clots.
20. PREVENTION OF DCM
•Don't smoke.
•Don't drink alcohol, or drink in moderation.
•Don't use cocaine or other illegal drugs.
•Eat a healthy diet that is low in salt (sodium).
•Maintain a healthy weight.
•Follow an exercise program recommended by your doctor.
•Get enough sleep and rest.
•Manage stress.
21. DEFINITION OF RCM
Restrictive cardiomyopathy tends to affect older adults. The heart's ventricles
become rigid because abnormal tissue, such as scar tissue, replaces the
normal heart muscle. Consequently, the ventricles can't relax normally and fill
with blood, and the atria become enlarged. Blood flow in the heart is reduced
over time. This can lead to problems such as heart failure or arrhythmias.
•OTHER name of RVM is
•Idiopathic restrictive cardiomyopathy
•Infiltrative cardiomyopathy
22. CAUSES OF RCM
•Hemochromatosis. (A disease in which too much iron builds up in your body.
The extra iron is toxic to the body and can damage the organs, including the
heart.)
•Sarcoidosis. (A disease that causes inflammation and can affect the body's
organs. Researchers believe that an abnormal immune response may cause
sarcoidosis. The abnormal response causes tiny lumps of cells to form in the
body's organs, including the heart.)
•Amyloidosis. (A disease in which abnormal proteins build up in the body's
organs, including the heart.) Amyloid light chain amyloidosis is a "protein misfolding
disorder." It causes organs and tissues, including the heart, kidney, skin, stomach,
small and large intestines, nerves and liver, to thicken and eventually lose function.
•Connective tissue disorders
•Some cancer treatments, such as radiation and chemotherapy
Drugs (serotonin, methysergide, ergotamine, mercurial agents, busulfan)
Radiation
diopathic
24. SIGNS AND SYMPTOMS OF RCM
•Shortness of breath (at first with exercise; but over time it occurs at rest)
•Fatigue (feeling overly tired)
•Inability to exercise
•Swelling of the legs and feet
•Weight gain
•Nausea, bloating, and poor appetite (related to fluid retention)
•Palpitations (fluttering in the chest due to abnormal heart rhythms)
Less common symptoms:
•Fainting (caused by irregular heart rhythms, abnormal responses of the blood
vessels during exercise, or no cause may be found)
•Chest pain or pressure (occurs usually with exercise or physical activity, but
can also occur with rest or after meals)
25. DIAGNOSTIC EVALUATION OF RCM
•Electrocardiogram (ECG), to check the heart rhythm
•Continuous portable ECG monitoring, to look at heart rhythms while you are
away from the healthcare provider’s office
•Chest X-ray, to see the heart size and anatomy
•Blood tests, to help assess the type of RCM
•Echocardiogram, to examine blood flow in the heart and how well the heart
pumps blood to the body
•Exercise testing, to see how your heart does during exercise
•Cardiac MRI, to further look at heart anatomy and coronary arteries
•Heart biopsy, to look at a small tissue sample from the heart in more detail
•Cardiac catheterization with coronary angiography. This looks at the arteries in
special cases, as well as measures pressures within the heart.
26. MANAGEMENT OF RCM
•Water pills (diuretics) to reduce swelling
•Medicine such as rate-lowering calcium channel blockers or beta-blockers
to reduce the heart’s workload and increase its efficiency
•Medicine such as ACE inhibitors to help the heart pump better
•Blood thinners (anticoagulants) to prevent blood clots if you have certain
abnormal heart rhythms
•Medicine to help prevent abnormal heart rhythms
•Lifestyle changes, such as cutting back on salt to reduce swelling
•Heart transplant. This may be considered in advanced cases.
27. DEFINITION ARVC
Arrhythmogenic right ventricular cardiomyopathy, or ARVC, is a type of
cardiomyopathy that affects
the ventricles (lower pumping chambers) of the heart and causes arrhythmias
(abnormal heart rhythms). It affects the right ventricle, and often also affects
the left ventricle. For this reason it is sometimes called arrhythmic
cardiomyopathy (as the main symptoms are arrhythmias). It doesn’t affect the
atria (upper chambers) of the heart.
28. CAUSES OF ARVD/C
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is
caused by abnormalities of structures that connect heart muscle cells together.
These structures are known as desmosomes.
ARVC is often ‘autosomal dominant’. This means that the mutated gene is found
on one of the non-sex
chromosomes (called the autosomes). A child of an affected parent will have a
50% chance of inheriting the gene mutation. In some cases it is ‘recessive’ (and
it therefore only develops into the
condition if both parents pass on the gene).
30. SIGNS AND SYMPTOMS OF ARVC
•Palpitations (feeling your heart beating too fast, too hard or like it is ‘fluttering’) – this is caused by
arrhythmias (when the electrical messages which control the heart’s rhythm are disrupted).
•Light-headedness and fainting (loss of consciousness) – reduced oxygen levels or blood flow to the brain, due to arrhythmias, can cause light-
headedness or dizziness and, in some cases, loss of consciousness.
•Swollen legs, ankles and tummy – build-up of fluid in the tissues, because the heart isn’t pumping
effectively, can cause swelling (called ‘oedema’).
•Breathlessness (or dyspnoea) – fluid builds-up around the lungs, making it harder to breathe. Due to the effect of ARVC on the electrical
signalling the in the heart, it often causes arrhythmias.
As ARVC affects the electrical signalling the in the heart, it often causes arrhythmias.
Arrhythmias
Arrhythmias are caused by the disruption of the normal electrical signalling in the heart that controls the heart beat. This disruption causes
a change in the heart’s rhythm, which means it beats too fast, too slow or erratically. Types of arrhythmias that can happen in ARVC include the
following.
•Atrial fibrillation (AF) – caused by disruption of the electrical messages that normally cause the heart muscle to contract. In AF the atria beat
very quickly and are uncoordinated. This can make the flow of blood around the atrium ‘turbulent’, and the heart less efficient at pumping out
blood. AF can cause palpitations and increase the risk of blood clots forming, which can increase the risk of a stroke.
•Ventricular premature beats (VPB) – this is an extra heart beat that happens when electrical impulses start in one of the ventricles, and it
contracts before it receives the normal signal via the atria. ARVC can sometimes cause an increase in the number and frequency of these extra
beats.
•Ventricular tachycardia (VT) – VT starts due to abnormal electrical activity in the ventricles, where
the heart contracts abnormally quickly (over 100 beats per minute). It can lead to loss of consciousness.
•Ventricular fibrillation (VF) – the contraction of the ventricles is uncoordinated, and they ‘quiver’ rather than contract normally, so blood is not
pumped out of the heart effectively. This condition is
life-threatening and requires urgent treatment with a defibrillator (see treatment below).
31. MANAGEMENT OF ARVC
•ACE inhibitors (angiotensin-converting enzyme inhibitors) – relax the smooth muscle around the
blood vessels to reduce the workload on the heart, and reduce the volume of the blood, making it
easier for the heart to work.
•Anti-arrhythmic medication – reduces abnormal heart rhythms and helps to control the normal
rhythm.
•Anticoagulants (blood thinners) – may be used in people with arrhythmias to reduce the risk of blood clots forming, which could lead to a
stroke.
•Angiotensin II Receptor Blockers (ARBs) – dilate (enlarge) the blood vessels which helps to reduce
blood pressure and may be used if the person is not able to tolerate ACE inhibitors.
•Beta-blockers – reduce the rate and force of the heart’s contraction, by reducing stimulation of
adrenalin (which would normally make the heart beat faster).
•Diuretics (water tablets) – reduce the build-up of fluid on the lungs or the ankles by encouraging the kidneys to get rid of water as urine.
•Pacemaker – may be recommended for people who have heart block (which makes the heart
rate slow down). Pacemakers control the electrical signalling of the heart to keep a normal heart rhythm.
•Cardioversion – this is a when an electric shock is given to the heart to try and control arrhythmias,
most commonly atrial fibrillation, and put the heart back into a normal rhythm. This is similar to what an ICD does (see below) but is a
procedure done in hospital.
•Catheter ablation – this uses radio waves to treat areas of the heart where the electrical pathways
cause arrhythmias. It stops the transmission of electrical signals that affect the normal heart rhythm.
•ICDs (implantable cardioverter defibrillator) – this may be recommended due to the risk of life-threatening arrhythmias. ICDs detect and
correct any dangerous arrhythmias which could otherwise lead to a cardiac arrest.
32. DEFINITION OF TTS
• Takotsubo cardiomyopathy or "Broken Heart Syndrome" is when the heart muscle
becomes suddenly stunned or weakened. It mostly occurs following severe emotional or
physical stress. The condition is temporary and most people recover within two moths.
t is also known as stress cardiomyopathy, apical ballooning, or broken heart syndrome.
Takotsubo cardiomyopathy most often affects women between the ages of 61 and 76 years. The
condition commonly occurs immediately after experiencing extreme emotional or physical stress.
Transient apical ballooning syndrome, apical ballooning cardiomyopathy, stress-induced
cardiomyopathy, broken-heart syndromeTHESE ARE OTHER NAME OF TTS

33. CAUSES OF TTS
Events that could trigger takotsubo cardiomyopathy include:
•the sudden death of a loved one
•domestic abuse
•natural disasters
•a motor vehicle accident
•a fierce argument
•relationship conflicts
•severe financial or gambling losses
•being diagnosed with a medical condition
•exhausting physical effort
•surgery
•acute medical illnesshead trauma
•public speaking
•extreme fright
Cases of takotsubo cardiomyopathy have also been reported after cocaine use, excessive stimulant drug use, or during opiate withdrawal.
People with certain mood disorders might be more likelyTrusted Source than others to develop takotsubo cardiomyopathy.
Some instances of takotsubo cardiomyopathy have occurred after positive stressful events, such as winning the lottery or a surprise party.
It is not understood why a specific stressful event will trigger this condition, but at a similar event may not do so at a different time.
Also, experts do not yet know why it is primarily older women that have takotsubo cardiomyopathy. A drop in estrogen activity may be a
contributing factor in older women.
34. SIGNS AND SYMPTOMS OF TTS
• Chest pain and shortness of breath after
severe stress (emotional or physical)
• Electrocardiogram abnormalities that mimic those of a heart
attack.
• No evidence of coronary artery obstruction.
• Movement abnormalities in the left ventricle.
• Ballooning of the left ventricle.
35. MANAGEMENT OF TTS
•ACE inhibitors to lower blood pressure (long term).
•Beta blockers to slow the heart rate (short term).
•Diuretics to decrease fluid buildup (short term).
•Anti-anxiety medicines to manage stress. (These medications may be
long term, if needed.)
Depending on how much your heart muscle was weakened, your
healthcare provider may also recommend cardiac rehabilitation.
Managing your stress with yoga, meditation and other relaxation
techniques can also be helpful. Ask your healthcare provider for
information on these methods and possible programs and services
available.
36. PREVENTION OF TTS
There are no known treatments for preventing broken heart syndrome. However, learning stress management and
problem-solving techniques can help improve physical and emotional stress.
Engaging in relaxation techniques can also be helpful. Some examples include:
•Practicing yoga, meditation, journaling, or mindfulness.
•Taking a warm bath; lighting scented candles; and taking long, deep breaths and slowly exhaling.
Depending on the source of your stress, there may be a support group you can join to talk about your stress and share
coping skills with others who have had similar experiences. Seeking the help of a professional counselor might be
considered too.
In addition, managing physical or emotional stress can be helped by following general healthy habits too.These
include:
•Eating a healthy diet, such as the Dash diet or Mediterranean diet.
•Getting regular exercise (at least five times a week for 30 minutes).
•Getting seven to nine hours of sleep each night.
•Spending time with others.
•Keeping your medical appointments, for both follow up and preventive health screenings. Finding and treating any
health problems early always leads to the best outcome for a long and healthy life.
•Avoid – or better yet – stop unhealthy choices such as smoking, illicit drug use, and alcohol abuse.
