Congestive Heart Failure, CHF, is due to a weakened heart that is not pumping blood efficiently. A few common causes of CHF include high blood pressure, heart attacks, heart valve abnormalities, and heart muscle diseases (cardiac myopathies). As a result of CHF, the heart is unable to pump enough blood to the muscles, tissues and organs of the body. Blood flow fails to move normally and fluid begins to pool, or become congested, in other areas of your body such as the lungs, legs and feet. In consultation with your cardiologist, CHF can be treated with medication, diet and lifestyle changes.
