Introduction
Heart failure is a chronic condition in which the heart is unable to pump blood effectively to meet the body’s needs. This does not mean the heart has stopped working, but rather that it is weaker or stiffer than normal. Heart failure can develop suddenly or gradually and often requires lifelong management. Early diagnosis and proper treatment can help people with heart failure live longer, healthier lives.
Causes
Heart failure can result from a variety of conditions that damage or weaken the heart, including coronary artery disease, high blood pressure, heart attacks, heart valve diseases, cardiomyopathies, congenital heart defects, and certain infections. Other risk factors include diabetes, obesity, smoking, excessive alcohol use, and some medications.
Symptoms
Symptoms of heart failure may develop slowly or appear suddenly. Common symptoms include shortness of breath (especially during activity or when lying down), fatigue, swelling in the legs, ankles, or feet, rapid or irregular heartbeat, persistent cough or wheezing, and difficulty exercising. Some people may also experience weight gain from fluid retention, loss of appetite, or confusion.
Diagnosis
Diagnosis involves a medical history, physical examination, and tests such as blood tests, electrocardiogram (ECG), echocardiogram (heart ultrasound), chest X-ray, and sometimes cardiac MRI or stress tests. If you experience symptoms of heart failure, consult a doctor for evaluation and appropriate testing.
Treatment Options
Treatment for heart failure focuses on managing symptoms, improving heart function, and preventing complications. Medications such as ACE inhibitors, beta-blockers, diuretics, and aldosterone antagonists are commonly used. In some cases, devices like pacemakers or implantable cardioverter-defibrillators (ICDs) may be needed. For severe cases, heart transplantation may be considered.
Simple measures such as following a low-salt diet, monitoring fluid intake, maintaining a healthy weight, exercising as advised by your doctor, and attending regular check-ups are important. If symptoms worsen or new issues arise, consult a doctor promptly.
Prevention
Preventing heart failure involves managing risk factors: control high blood pressure, treat heart disease, avoid smoking, limit alcohol, maintain a healthy weight, and exercise regularly. Early treatment of heart conditions and regular check-ups are key.
Takeaway
Heart failure is a serious but manageable condition. With early diagnosis, proper treatment, and lifestyle changes, many people with heart failure can lead active, fulfilling lives. If you have symptoms or risk factors, consult a doctor for assessment and support.
