Heart failure is a decreased ability of the heart to fill and empty. The major purpose of the heart is to circulate blood, which carries oxygen and nutrients around the body, including itself).
Depending on what part of the heart is involved, impaired pumping may result in fluid retention in your lungs and shortness of breath (Congestive Heart Failure or CHF), or other parts of your body (peripheral edema). When your motor doesn’t work well heart failure is also associated with a decreased ability to do things and early fatigue.
The most common cause of heart failure is CAD.
If heart failure is caused by permanent damage from previous heart attacks, increased blood supply may not help improve heart function. However, if there is impaired blood supply to an otherwise healthy heart muscle, restoring the blood flow back to normal may improve heart function significantly.
Heart failure may be the result of one or many factors. Whatever the cause, it results in the inability to supply sufficient blood flow to meet the body’s needs.
