<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\nHave you ever wondered why heart failure is becoming a major health crisis in India? With increasing cases linked to high blood pressure, diabetes, and changing lifestyles, it has become a major health concern 1<\/a><\/sup>.<\/p>\n\n\n\n
In fact, studies have shown that every year, 0.4% to 2.3% Indians develop heart failure due to coronary heart disease which could lead to fatal outcomes 2<\/a>,3<\/a><\/sup>. Addressing this challenge requires better public awareness, early detection, and stronger healthcare support 1<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
<\/span>What is Heart Failure?<\/strong><\/span><\/h2>\n\n\n\nHeart failure, also known as congestive heart failure, occurs when the heart is unable to pump enough blood to meet your body\u2019s needs. Despite its name, heart failure does not mean the heart has stopped working, but it is a serious condition requiring medical care 4<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
A healthy heart pumps oxygen-rich blood to organs and tissues. In heart failure, one or both sides of the heart struggle to circulate blood properly. Your heart may not be able to fill enough blood, or your heart may be too weak to pump blood properly. Heart failure can be divided into right heart failure and left heart failure 4<\/a>,5<\/a><\/sup>.<\/p>\n\n\n\n
\n
Left-sided heart failure:<\/strong> This occurs when the left ventricle fails to pump blood effectively, leading to fluid buildup in the body including lungs. Common causes include hypertension, coronary artery disease, and myocardial infarction.\u00a0<\/li>\n\n\n\n
Right-sided heart failure:<\/strong> This is when the right ventricle cannot pump blood efficiently causing fluid retention in the body (legs, abdomen). The main causes of right heart failure include left-sided heart failure, pulmonary hypertension, or chronic lung diseases.\u00a0<\/li>\n<\/ul>\n\n\n\n
Whatever be the causes of right heart failure or left heart failure, it can lead to life-threatening consequences if not managed properly 4<\/a>,6<\/a><\/sup>.<\/p>\n\n\n\n
<\/span>Causes of Heart Failure<\/strong><\/span><\/h2>\n\n\n\nAre you wondering what causes heart failure<\/strong>? It often results from the added strain caused by certain health issues that either damage the heart or force it to work harder than it should7<\/a>,8<\/a><\/sup>.<\/p>\n\n\n\n
The main causes of heart failure<\/strong> include:<\/p>\n\n\n\n
\n
Coronary Artery Disease:<\/strong> Coronary artery disease occurs when your blood vessels supplying the heart become hardened and narrowed due to deposition of material known as plaque. Fatty deposits in the heart\u2019s arteries reduce blood flow and oxygen which can lead to heart failure9<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
Past Heart Attack (Myocardial Infarction)<\/strong>: A heart attack occurs when an artery blockage restricts blood flow, damaging heart tissue and weakening its pumping ability, potentially causing heart failure.\u00a0<\/li>\n\n\n\n
Abnormal Heart Valves<\/strong>: Heart valve problems can occur due to disease, infection (such as endocarditis), or defects present at birth. The reasons for heart failure in these conditions is your heart valves not opening or closing fully. In such cases, your heart must work harder to pump blood, which may lead to heart failure.\u00a0<\/li>\n\n\n\n
Heart Muscle Disease (Cardiomyopathy)<\/strong>: Conditions like dilated cardiomyopathy (enlarged or stiffened heart) or myocarditis (heart muscle inflammation) can weaken the heart, reducing its ability to pump blood and causing heart failure.\u00a0<\/li>\n\n\n\n
Congenital Heart Defects<\/strong>: Heart defects present from birth can cause parts of the heart to be malformed or not work correctly. As a result, the healthy parts of your heart must work harder to compensate, which can eventually lead to heart failure.\u00a0<\/li>\n\n\n\n
Other Conditions: <\/strong>Several factors may cause temporary heart strain, leading to heart failure symptoms:\n\n
Hypertension<\/strong>: High blood pressure may overwork and weaken the heart10<\/a><\/sup>.<\/li>\n\n\n\n
Severe Anaemia<\/strong>: Low red blood cells may reduce oxygen, making the heart work harder.\u00a0<\/li>\n\n\n\n
Hyperthyroidism<\/strong>: An overactive thyroid may increase heart strain.\u00a0<\/li>\n\n\n\n
Arrhythmia<\/strong>: The reason for heart failure is that irregular heart rhythms may prevent efficient blood pumping.\u00a0<\/li>\n<\/ul>\n<\/li>\n<\/ul><\/div>
