Heart failure is a medical condition in which the heart is no longer able to pump blood effectively throughout the body. Symptoms of heart failure can include shortness of breath, fatigue, and swelling in the lower legs and feet. Diagnosis of heart failure is made by a combination of physical examination, laboratory tests, and imaging tests. Treatment of heart failure can include lifestyle changes, medications, and in some cases, surgery. Lifestyle changes may include dietary modifications, reducing salt intake, and exercise. Medications may include diuretics, ACE inhibitors, beta blockers, and others. Surgery may include coronary artery bypass grafting, ventricular assist devices, and heart transplantation.
