Heart Failure


Heart Failure Heart failure doesn’t mean your heart stops working. It means the heart can’t pump enough blood to meet the body’s needs. Over time, the heart gets bigger to hold more blood, it pumps faster to increase the amount of blood moving out of it, and the blood vessels narrow. The heart muscle may also weaken, reducing the blood supply even more. Most cases of heart failure are the result of coronary artery disease and heart attacks.
