Heart failure is a chronic condition in which the heart cannot pump enough blood to meet the body's needs. It can be caused by a variety of medical conditions, such as coronary heart disease, high blood pressure, heart valve disease, myocarditis, congenital heart disease, diabetes, and obesity.
Symptoms may include fatigue, shortness of breath, swelling in the ankles and feet, sudden weight gain, persistent cough, and dizziness. Treatment for heart failure may include lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising regularly, as well as medication and, in some cases, medical procedures or surgery.
It is important for people experiencing these symptoms to seek medical attention immediately, as early diagnosis and appropriate treatment can improve quality of life and prevent serious complications.
