The term “heart failure” sounds like a sudden, potentially fatal condition. But heart failure is a chronic condition that develops as the heart’s ability to pump blood decreases gradually. Symptoms range from mild to severe. The body becomes deprived of oxygen as blood moves too slowly, causing patients to feel tired and short of breath. Symptoms depend on which pumping system is affected – the left pump sends blood to the body, while the right side sends blood to the lungs to be oxygenated. Heart failure can develop from an underlying condition like coronary artery disease (heart disease), a heart attack, or scar tissue from a heart attack. Certain infections and other diseases may also contribute to heart failure.
P.S. Lifestyle adjustments (diet, exercise, smoking cessation) and medications are treatment options for heart failure.
