What is Heart Failure?
Heart failure means your heart is not pumping well. This does not mean that your heart has stopped beating. Your heart still beats, but it pumps less nutrient-and-oxygen-rich blood to the rest of your body. Because of this, heart failure can make you feel tired or weak. Heart failure can also cause swelling and fluid buildup in your legs, feet, and even your lungs. Fluid Backing up into the lungs is often referred to as "congestion," which is why heart failure is sometimes called "congestive heart failure" or CHF.
What Causes Heart Failure?
Heart failure usually occurs when another problem makes the heart weak or stiff so it doesn't pump or fill normally. Causes of heart failure include: coronary artery, a previous heart attack, problems with the heart valves, enlargement or infection of the heart muscle, and high blood pressure.
