Heart failure is a chronic condition in which the heart is unable to pump blood efficiently to meet the body’s needs. This can happen when the heart becomes too weak or too stiff to function properly. Common causes include high blood pressure, coronary artery disease, heart attacks, and conditions like diabetes. Symptoms of heart failure include shortness of breath, fatigue, swelling in the legs and ankles, rapid heartbeat, and persistent coughing or wheezing. If left untreated, it can lead to serious complications such as organ damage, fluid buildup in the lungs, and even death. Management of heart failure involves lifestyle changes, such as a low-sodium diet, regular exercise, and weight management, along with medications like beta-blockers, diuretics, and ACE inhibitors. In severe cases, medical devices or heart transplants may be needed. Early diagnosis and proper treatment can help improve quality of life and slow disease progression.
