Q. What is heart failure, and what causes it?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Heart failure, often referred to as congestive heart failure (CHF), is a chronic medical condition where the heart struggles to pump blood effectively, causing a reduced supply of oxygen and nutrients to the body's tissues.
Causes of heart failure can vary, but the common denominator is a heart that's unable to keep up with its workload. Let's dive into the intricacies:
1. Coronary Artery Disease (CAD): One of the leading culprits. CAD narrows or blocks the arteries that supply blood to the heart muscle. When the heart muscle doesn't get enough blood, it weakens over time.
2. High Blood Pressure (Hypertension): The heart has to work harder to pump blood when blood pressure is consistently high. This extra strain can lead to heart muscle thickening and, eventually, heart failure.
3. Cardiomyopathy: This term encompasses various conditions where the heart muscle becomes enlarged, thick, or rigid. This weakens the heart's ability to pump blood effectively.
4. Heart Valve Disorders: Faulty heart valves can disrupt blood flow and force the heart to compensate, potentially leading to heart failure.
5. Heart Attack: Damage from a heart attack can weaken the heart muscle, impairing its pumping ability and setting the stage for heart failure.
6. Other Causes: There are numerous other factors, such as infections, alcohol or drug abuse, congenital heart defects, and certain medications, that can contribute to heart failure.
Prevention plays a pivotal role. Managing risk factors like high blood pressure, diabetes, and adopting a heart-healthy lifestyle with a balanced diet, regular exercise, and avoiding smoking can significantly reduce your risk.
Early diagnosis is essential. Common symptoms of heart failure include shortness of breath, fatigue, swollen legs or ankles, and an irregular heartbeat. If you or a loved one experience these symptoms, seek medical attention promptly.
Treatment varies based on the underlying cause and the severity of heart failure. Medications, lifestyle changes, and sometimes surgical interventions, such as heart bypass surgery or heart transplant, may be necessary.
In conclusion, heart failure is a serious medical condition with various underlying causes. It's crucial to understand the risk factors, recognize the symptoms, and take proactive steps to maintain heart health. By doing so, you can reduce the risk of heart failure and lead a healthier, more vibrant life.
