Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs. It can develop over time as the heart's pumping action weakens due to conditions like coronary heart disease, high blood pressure, and diabetes damaging the heart. Treatment focuses on managing the underlying cause, reducing symptoms, and preventing worsening through lifestyle changes, medications, medical procedures if needed, and ongoing monitoring.
Congestive heart failure (CHF) is a chronic progressive condition that affects the pumping power of your heart muscles. While often referred to simply as “heart failure,” CHF specifically refers to the stage in which fluid builds up around the heart and causes it to pump inefficiently. You have four heart chambers.

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest.
Heart disease describes a range of conditions that affect your heart. Heart diseases include:
Blood vessel disease, such as coronary artery disease
Heart rhythm problems (arrhythmias)
Heart defects you're born with (congenital heart defects)
Heart valve disease
Disease of the heart muscle
Heart infection
Many forms of heart disease can be prevented or treated with healthy lifestyle choices.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. What Is Heart Failure?
Heart failure is a condition in which the heart can't pump
enough blood to meet the body's needs. In some cases, the
heart can't fill with enough blood. In other cases, the
heart can't pump blood to the rest of the body with
enough force. Some people have both problems.
The term "heart failure" doesn't mean that your heart has
stopped or is about to stop working. However, heart
failure is a serious condition that requires medical care.
3. Overview
Heart failure develops over time as the heart's pumping
action grows weaker. The condition can affect the right
side of the heart only, or it can affect both sides of the
heart. Most cases involve both sides of the heart.
Right-side heart failure occurs if the heart can't pump
enough blood to the lungs to pick up oxygen. Left-side
heart failure occurs if the heart can't pump enough
oxygen-rich blood to the rest of the body.
4. Right-side heart failure may cause fluid to build up in the
feet, ankles, legs, liver, abdomen, and the veins in the
neck. Right-side and left-side heart failure also may cause
shortness of breath and fatigue (tiredness).
The leading causes of heart failure are diseases that
damage the heart. Examples include
coronary heart disease (CHD), high blood pressure, and
diabetes.
5. What Causes Heart Failure?
Causes of heart failure include:
Coronary heart disease
Diabetes
High blood pressure
Other heart conditions or diseases
6. Coronary Heart Disease
Coronary heart disease is a condition in which a waxy
substance called plaque builds up inside the coronary
arteries. These arteries supply oxygen-rich blood to your
heart muscle.
Plaque narrows the arteries and reduces blood flow to
your heart muscle. The buildup of plaque also makes it
more likely that blood clots will form in your arteries.
Blood clots can partially or completely block blood flow.
Coronary heart disease can lead to chest pain or
discomfort called angina, a heart attack, and heart
damage.
7. Diabetes
Diabetes is a disease in which the body’s blood glucose
(sugar) level is too high. The body normally breaks down
food into glucose and then carries it to cells throughout
the body. The cells use a hormone called insulin to turn
the glucose into energy.
In diabetes, the body doesn’t make enough insulin or
doesn’t use its insulin properly. Over time, high blood
sugar levels can damage and weaken the heart muscle and
the blood vessels around the heart, leading to heart
failure.
8. Blood Pressure
Blood pressure is the force of blood pushing against the
walls of the arteries. If this pressure rises and stays high
over time, it can weaken your heart and lead to plaque
buildup.
Blood pressure is considered high if it stays at or above
140/90 mmHg over time. (The mmHg is millimeters of
mercury—the units used to measure blood pressure.) If you
have diabetes or chronic kidney disease, high blood
pressure is defined as 130/80 mmHg or higher.
9. Other Heart Conditions
Other conditions and diseases also can lead to heart
failure, such as:
Arrhythmia. Happens when a problem occurs with the rate
or rhythm of the heartbeat.
Cardiomyopathy. Happens when the heart muscle
becomes enlarged, thick, or rigid.
Congenital heart defects. Problems with the heart’s
structure are present at birth.
Heart valve disease. Occurs if one or more of your heart
valves doesn’t work properly, which can be present at
birth or caused by infection, other heart conditions, and
age.
10. Other factors also can injure the heart muscle and lead to
heart failure. Examples include:
Alcohol abuse or cocaine and other illegal drug use
HIV/AIDS
Thyroid disorders (having either too much or too little
thyroid hormone in the body)
Too much vitamin E
Treatments for cancer, such as radiation and
chemotherapy
11. Who Is at Risk for Heart Failure?
People who are age 65 or older. Aging can weaken the
heart muscle. Older people also may have had diseases for
many years that led to heart failure. Heart failure is a
leading cause of hospital stays among people on Medicare.
Blacks are more likely to have heart failure than people of
other races. They’re also more likely to have symptoms at
a younger age, have more hospital visits due to heart
failure, and die from heart failure.
People who are overweight. Excess weight puts strain on
the heart. Being overweight also increases your risk of
heart disease and type 2 diabetes. These diseases can lead
to heart failure.
12. People who have had a heart attack. Damage to the heart
muscle from a heart attack and can weaken the heart
muscle.
Children who have congenital heart defects also can
develop heart failure. These defects occur if the heart,
heart valves, or blood vessels near the heart don’t form
correctly while a baby is in the womb. Congenital heart
defects can make the heart work harder. This weakens the
heart muscle, which can lead to heart failure. Children
don’t have the same symptoms of heart failure or get the
same treatments as adults. This Health Topic focuses on
heart failure in adults.
13. Signs & Symptoms
The most common signs and symptoms of heart failure are:
Shortness of breath or trouble breathing
Fatigue (tiredness)
Swelling in the ankles, feet, legs, abdomen, and veins in
the neck
All of these symptoms are the result of fluid buildup in
your body. When symptoms start, you may feel tired and
short of breath after routine physical effort, like climbing
stairs.
14. As your heart grows weaker, symptoms get worse. You
may begin to feel tired and short of breath after getting
dressed or walking across the room. Some people have
shortness of breath while lying flat.
Fluid buildup from heart failure also causes weight gain,
frequent urination, and a cough that's worse at night and
when you're lying down. This cough may be a sign of acute
pulmonary edema (e-DE-ma). This is a condition in which
too much fluid builds up in your lungs. The condition
requires emergency treatment.
15. Diagnosis
Medical and Family Histories
Your doctor will ask whether you or others in your family
have or have had a disease or condition that can cause heart
failure.
Your doctor also will ask about your symptoms. He or she
will want to know which symptoms you have, when they
occur, how long you've had them, and how severe they are.
Your answers will help show whether and how much your
symptoms limit your daily routine.
16. Physical Exam
During the physical exam, your doctor will:
Listen to your heart for sounds that aren't normal
Listen to your lungs for the sounds of extra fluid buildup
Look for swelling in your ankles, feet, legs, abdomen, and
the veins in your neck
17. Diagnostic Tests
No single test can diagnose heart failure. If you have signs
and symptoms of heart failure, your doctor may recommend
one or more tests.
Your doctor also may refer you to a cardiologist. A
cardiologist is a doctor who specializes in diagnosing and
treating heart diseases and conditions.
18. EKG (Electrocardiogram)
An EKG is a simple, painless test that detects and records
the heart's electrical activity. The test shows how fast your
heart is beating and its rhythm (steady or irregular). An EKG
also records the strength and timing of electrical signals as
they pass through your heart.
An EKG may show whether the walls in your heart's
pumping chambers are thicker than normal. Thicker walls
can make it harder for your heart to pump blood. An EKG
also can show signs of a previous or current heart attack.
19. Chest X Ray
A chest x ray takes pictures of the structures inside your
chest, such as your heart, lungs, and blood vessels. This test
can show whether your heart is enlarged, you have fluid in
your lungs, or you have lung disease.
BNP Blood Test
This test checks the level of a hormone in your blood called
BNP. The level of this hormone rises during heart failure.
20. Echocardiography
Echocardiography (echo) uses sound waves to create a
moving picture of your heart. The test shows the size and
shape of your heart and how well your heart chambers and
valves work.
Echo also can identify areas of poor blood flow to the
heart, areas of heart muscle that aren't contracting
normally, and heart muscle damage caused by lack of
blood flow.
Echo might be done before and after a stress test (see
below). A stress echo can show how well blood is flowing
through your heart. The test also can show how well your
heart pumps blood when it beats.
21. Doppler Ultrasound
A Doppler ultrasound uses sound waves to measure the speed and
direction of blood flow. This test often is done with echo to give a
more complete picture of blood flow to the heart and lungs.
Doctors often use Doppler ultrasound to help diagnose right-side heart
failure.
Holter Monitor
A Holter monitor records your heart's electrical activity for a full 24-
or 48-hour period, while you go about your normal daily routine.
You wear small patches called electrodes on your chest. Wires
connect the patches to a small, portable recorder. The recorder can
be clipped to a belt, kept in a pocket, or hung around your neck.
22. Nuclear Heart Scan
A nuclear heart scan shows how well blood is flowing
through your heart and how much blood is reaching your
heart muscle.
During a nuclear heart scan, a safe, radioactive substance
called a tracer is injected into your bloodstream through a
vein. The tracer travels to your heart and releases energy.
Special cameras outside of your body detect the energy and
use it to create pictures of your heart.
23. A nuclear heart scan can show where the heart muscle is
healthy and where it's damaged.
A positron emission tomography (PET) scan is a type of
nuclear heart scan. It shows the level of chemical activity
in areas of your heart. This test can help your doctor see
whether enough blood is flowing to these areas. A PET
scan can show blood flow problems that other tests might
not detect.
24. Cardiac Catheterization
During cardiac catheterization (KATH-eh-ter-ih-ZA-shun), a
long, thin, flexible tube called a catheter is put into a blood
vessel in your arm, groin (upper thigh), or neck and threaded
to your heart. This allows your doctor to look inside your
coronary (heart) arteries.
During this procedure, your doctor can check the pressure
and blood flow in your heart chambers, collect blood
samples, and use x rays to look at your coronary arteries.
25. Coronary Angiography
Coronary angiography (an-jee-OG-rah-fee) usually is done with cardiac
catheterization. A dye that can be seen on x ray is injected into your
bloodstream through the tip of the catheter.
The dye allows your doctor to see the flow of blood to your heart muscle.
Angiography also shows how well your heart is pumping.
Stress Test
Some heart problems are easier to diagnose when your heart is working hard
and beating fast. During stress testing, you exercise to make your heart work
hard and beat fast.
You may walk or run on a treadmill or pedal a bicycle. If you can't exercise, you
may be given medicine to raise your heart rate.
Heart tests, such as nuclear heart scanning and echo, often are done during
stress testing.
26. Cardiac MRI
Cardiac MRI (magnetic resonance imaging) uses radio waves, magnets,
and a computer to create pictures of your heart as it's beating. The test
produces both still and moving pictures of your heart and major blood
vessels.
A cardiac MRI can show whether parts of your heart are damaged.
Doctors also have used MRI in research studies to find early signs of heart
failure, even before symptoms appear.
Thyroid Function Tests
Thyroid function tests show how well your thyroid gland is working.
These tests include blood tests, imaging tests, and tests to stimulate the
thyroid. Having too much or too little thyroid hormone in the blood can
lead to heart failure.
27. Treatment
Treatment for heart failure depends on the type and severity of the
heart failure.
The goals of treatment for all stages of heart failure include:
Treating the condition’s underlying cause, such as
coronary heart disease, high blood pressure, or diabetes
Reducing symptoms
Stopping the heart failure from getting worse
Increasing your lifespan and improving your quality of life
Treatments usually include heart-healthy lifestyle changes, medicines
, and ongoing care. If you have severe heart failure, you also may
need medical procedures or surgery.
28. Heart-Healthy Lifestyle Changes
Your doctor may recommend heart-healthy lifestyle
changes if you have heart failure. Heart-healthy lifestyle
changes include:
Heart-healthy eating
Aiming for a healthy weight
Physical activity
Quitting smoking
29. Medicines
Your doctor will prescribe medicines based on the type of heart failure
you have, how severe it is, and your response to certain medicines. The
following medicines are commonly used to treat heart failure:
ACE inhibitors lower blood pressure and reduce strain on your heart.
They also may reduce the risk of a future heart attack.
Aldosterone antagonists trigger the body to remove excess sodium
through urine. This lowers the volume of blood that the heart must
pump.
30. Angiotensin receptor blockers relax your blood vessels
and lower blood pressure to decrease your heart’s
workload.
Beta blockers slow your heart rate and lower your blood
pressure to decrease your heart’s workload.
Digoxin makes the heart beat stronger and pump more
blood.
Diuretics (fluid pills) help reduce fluid buildup in your
lungs and swelling in your feet and ankles.
31. Isosorbide dinitrate/hydralazine hydrochloride helps
relax your blood vessels so your heart doesn’t work as
hard to pump blood. Studies have shown that this
medicine can reduce the risk of death in blacks. More
studies are needed to find out whether this medicine will
benefit other racial groups.
32. Ongoing Care
You should watch for signs that heart failure is getting worse. For
example, weight gain may mean that fluids are building up in your body.
Ask your doctor how often you should check your weight and when to
report weight changes.
Getting medical care for other related conditions is important. If you
have diabetes or high blood pressure, work with your health care team
to control these conditions. Have your blood sugar level and blood
pressure checked. Talk with your doctor about when you should have
tests and how often to take measurements at home.
Try to avoid respiratory infections like the flu and pneumonia. Talk
with your doctor or nurse about getting flu and pneumonia vaccines.
33. Medical Procedures and Surgery
As heart failure worsens, lifestyle changes and medicines may no
longer control your symptoms. You may need a medical procedure or
surgery.
In heart failure, the right and left sides of the heart may no longer
contract at the same time. This disrupts the heart’s pumping. To
correct this problem, your doctor might implant a cardiac
resynchronization therapy device (a type of pacemaker) near your
heart. This device helps both sides of your heart contract at the same
time, which can decrease heart failure symptoms.
Some people who have heart failure have very rapid, irregular
heartbeats. Without treatment, these heartbeats can cause sudden
cardiac arrest. Your doctor might implant an implantable cardioverter
defibrillator (ICD) near your heart to solve this problem. An ICD
checks your heart rate and uses electrical pulses to correct irregular
heart rhythms.
34. People who have severe heart failure symptoms at rest,
despite other treatments, may need:
A mechanical heart pump, such as a left ventricular assist
device. This device helps pump blood from the heart to
the rest of the body. You may use a heart pump until you
have surgery or as a long-term treatment.
Heart transplant. A heart transplant is an operation in
which a person’s diseased heart is replaced with a healthy
heart from a deceased donor. Heart transplants are done
as a life-saving measure for end-stage heart failure when
medical treatment and less drastic surgery have failed.
