Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.

JNC7 is the national clinical guideline that was developed to aid clinicians in the management of hypertension.
Heart failure (HF) is a common cardiovascular condition with increasing incidence and prevalence. Unlike western countries where heart failure is predominantly a disease of elderly, in India it affects younger age group. Heart failure is a chronic condition in which the heart cannot pump enough blood and oxygen to support other organs in your body.
Ischemic heart disease (IHD) caused by atherosclerosis of the epicardial vessels leading to coronary heart disease (CHD) is the main etiology of IHD.
Leading cause of death
Resulting from myocardial ischemia—an imbalance between the supply (perfusion) and demand of the heart for oxygenated blood.
90% of cases, the cause of myocardial ischemia is reduced blood flow due to obstructive atherosclerotic lesions in the coronary arteries.
IHD is often termed coronary artery disease (CAD) or coronary heart disease.
There is a long period (up to decades) of silent, slow progression of coronary lesions before symptoms appear.
IHD are only the late manifestations of coronary atherosclerosis that may have started during childhood or adolescence
Angina also known as angina pectoris is a medical condition characterized by chest pain usually left sided due to inadequate blood supply (ischemia) to the heart muscles due to obstruction (like presence of blood clot), narrowing or contraction (vasospasm) of the supplying coronary arteries.

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.

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!
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

2. HEART FAILURE
Defined as the pathophysiologic state in which impaired cardiac
function is unable to maintain an adequate circulation for the
metabolic needs of the tissues of the body.
It may be acute o r chro nic.
The te rm co ng e stive he art failure (CHF) is used for the chronic form
of heart failure in which the patient has evidence of congestion of
peripheral circulation and of lungs.
CHF is the end-result of various forms of serious heart diseases.
3. ETIOLOGY
Heart failure may be caused by one of the following
factors, either singly or in combination:
1. Instrinsic pump failure
2. increased workload on heart
3. impaired filling of cardiac chambers
4. 1. INTRINSIC PUMPFAILURE.
The most common and most important cause of heart failure is
weakening of the ventricular muscle due to disease so that the heart
fails to act as an efficient pump. The various diseases which may
culminate in pump failure by this mechanisms are as under:
Ischaemic heart disease
Myocarditis
Cardiomyopathies
Metabolic disorders e.g. beriberi
Disorders of the rhythm e.g. atrial fibrillation and flutter.
5. 2. INCREASEDWORKLOADON THE HEART.
Increased mechanical load on the heart results in increased
myocardial demand resulting in myocardial failure.
Increased load on the heart may be in the form of pressure load
or volume load.
Increased pressure load
a) Systemic and pulmonary
arterial hypertension.
b) Valvular disease e.g. mitral
stenosis, aortic stenosis,
pulmonary stenosis.
c) Chronic lung diseases.
Increased volume load
a) Valvular insufficiency
b) Severe anaemia
c) Thyrotoxicosis
d) Arteriovenous shunts
e) Hypoxia due to lung
diseases.
6. 3. IMPAIREDFILLING OF CARDIAC CHAMBERS.
Decreased cardiac output and cardiac failure may result from extra-
cardiac causes or defect in filling of the heart:
Cardiac tamponade (Compression of heart) e.g. haemopericardium,
hydropericardium
Constrictive pericarditis.
7. TYPES OF HEART FAILURE
Heart failure may be
Acute orchronic
Right-sided orleft sided
Forward orbackward failure.
ACUTE ANDCHRONIC HEART FAILURE. Depending upon whether
the heart failure develops rapidly or slowly, it may be acute or
chronic.
Acute heart failure. Sudden and rapid development of heart failure
occurs in the following conditions:
i) Larger myocardial infarction v) Acute viral myocarditis
ii) Valve rupture iv) Massive pulmonary
embolism
iii) Cardiac tamponade vi) Acute bacterial toxaemia.
8. Chronic heart failure. More often, heart failure develops
Myocardial ischaemia
Multi valvular heart disease
Systemic arterial hypertension
Chronic lung diseases resulting in hypoxia and pulmonary arterial
hypertension
Progression of acute into chronic failure.
In chronic heart failure, compensatory mechanisms like tachycardia,
cardiac dilatation and cardiac hypertrophy try to make adjustments
so as to maintain adequate cardiac output.
9. LEFT-SIDED AND RIGHT-SIDED HEART
FAILURE.
Though heart as an organ eventually fails as a whole, but
functionally, the left and right heart act as independent units.
From clinical point of view, therefore, it is helpful to consider
failure of the left and right heart separately.
The clinical manifestations of heart failure result from
accumulation of excess fluid upstre am to the le ft o r rig ht
cardiac cham be r whichever is initially affected
10. Left-sided heart failure. It is initiated by stress to the left heart. The
major causes are as follows:
Systemic hypertension
Mitral or aortic valve disease (stenosis)
Ischaemic heart disease
Myocardial diseases e.g. cardiomyopathies, myocarditis.
Restrictive pericarditis.
11. The clinical manifestations of left-sided heart failure result from
decreased left ventricular output and hence there is accumulation of
fluid upstre am in the lung s.
Acco rding ly, the major pathologic changes are as under:
i) Pulmonary congestion and oedema causes dyspnoea and
orthopnoea
ii) Decreased left ventricular output causing hypoperfusion and
diminished oxygenation of tissues
12. Right-sided heart failure occurs more often as a consequence of
left-sided heart failure.
However, some conditions affect the right ventricle primarily,
producing right-sided heart failure. These are as follows:
i) As a consequence of left ventricular failure.
ii) Corpulmonale in which right heart failure occurs due to intrinsic
lung diseases
iii) Pulmonary or tricuspid valvular disease.
iv) Pulmonary hypertension secondary to pulmonary
thromboembolism.
v) Myocardial disease affecting right heart.
.
13. BACKWARD AND FORWARD HEART
FAILURE.
The mechanism of clinical manifestations resulting from heart failure
can be explained on the basis of mutually interdependent backward
and forward failure.
Backward heart failure. According to this concept, either of the
ventricles fails to eject blood normally, resulting in rise of end-
diastolic volume in the ventricle and increase in volume and pressure
in the atrium which is transmitted backward producing elevated
pressure in the veins.
Forward heart failure. According to this hypothesis, clinical
manifestations result directly from failure of the heart to pump blood
causing diminished flow of blood to the tissues, especially diminished
renal perfusion and activation of reninangiotensin-aldosterone
system.
14. COMPENSATORY
MECHANISMS:
CARDIAC HYPERTROPHY ANDDILATATION
In order to maintain normal cardiac output, several compensatory
mechanisms play a role as under:
Compensatory enlargement in the form of cardiac hype rtro phy,
cardiac dilatatio n, o r bo th.
Tachycardia (i. e . incre ase d he art rate ) due to activatio n o f
neurohumoral system e.g. release of norepinephrine and atrial
natrouretic peptide,
activation of renin-angiotensinaldosterone mechanism.
15.
16. CARDIAC HYPERTROPHY
Hypertrophy of the heart is defined as an increase in size and
weight of the myocardium. It generally results from increased
pressure load while increased volume load (e.g. valvular
incompetence) results in hypertrophy with dilatation of the
affected chamber due to regurgitation of the blood through
incompetent valve. The atria may also undergo compensatory
changes due to increased workload.
The basic factors that stimulate the hypertrophy of the
myocardial fibres are not known. It appears that stretching of
myocardial fibres in response to stress induces the cells to
increase in length. The elongated fibres receive better nutrition
and thus increase in size. Other factors which may stimulate
increase in size of myocardial fibres are anoxia (e.g. in
coronary atherosclerosis) and influence of certain hormones
(e.g. catecholamines, pituitary growth hormone).
17. CAUSES. Hypertrophy with orwithout dilatation may involve
predominantly the left or the right heart, or both sides.
Left ventricularhypertrophy. The common causes are as
under:
i) Systemic hypertension
ii) Aortic stenosis and insufficiency
iii) Mitral insufficiency
iv) Coarctation of the aorta
v) Occlusive coronary artery disease
vi) Congenital anomalies like septal defects and patent ductus
arteriosus
vii) Conditions with increased cardiac output e.g. thyro-
toxicosis, anaemia, arteriovenous fistulae.
18. Right ventricularhypertrophy. Most of the causes of right
ventricular hypertrophy are due to pulmonary arterial
hypertension. These are as follows:
i) Pulmonary stenosis and insufficiency
ii) Tricuspid insufficiency
iii) Mitral stenosis and/or insufficiency
iv) Chronic lung diseases e.g. chronic emphysema,
bronchiectasis, pneumoconiosis, pulmonary vascular disease
etc.
v) Left ventricular hypertrophy and failure of the left ventricle.
19. CARDIAC DILATATION
Quite often, hypertrophy of the heart is accompanied by
cardiac dilatation. Stress leading to accumulation of excessive
volume of blood in a chamber of the heart causes increase in
length of myocardial fibres and hence cardiac dilatation as a
compensatory mechanism.
20. CAUSES. Accumulation of excessive volume of blood within
the cardiac chambers from the following causes may result in
dilatation of the respective ventricles or both:
i) Valvular insufficiency (mitral and/or aortic insufficiency
in left ventricular dilatation, tricuspid and/or pulmonary
insufficiency in right ventricular dilatation)
ii) Left-to-right shunts e.g. in VSD
iii) Conditions with high cardiac output e.g. thyrotoxicosis,
arteriovenous shunt
iv) Myocardial diseases e.g. cardiomyopathies, myocarditis
v) Systemic hypertension.
