What is congestive heart failure?
Congestive heart failure is a serious condition in which the
heart's pumping action is compromised. In the early stages, heart
failure may not have any symptoms. In the later stages, you may
have severe symptoms because your weakened heart is unable to pump
enough oxygen-rich blood with each contraction to satisfy the body.
These symptoms may include shortness of breath, or dyspnea, that
initially occurs only during exercise, and later even while at
rest.
How common is congestive heart failure?
According to the American Heart Association, heart failure affects
about 5 million Americans, with more than half a million new cases
diagnosed every year. Interestingly, while the incidence of other
cardiac diseases remains stable or varies only slightly, the
incidence of heart failure has increased significantly over the
last three decades. This is because of the aging population and
doctors' increased ability to treat other cardiac diseases. In the
1970s, high blood pressure was the leading cause of heart failure.
Today, because of the increased survival due to treatments such as
bypass surgery and balloon angioplasty, coronary artery disease is
the leading cause of the condition.
How dangerous is congestive heart
failure?
It is a very serious condition. According to statistics from the
American Heart Association, there are about 5 million heart failure
patients in the United States, and 550,000 new cases of heart
failure are diagnosed in the United States every year. This
includes 10 out of every 1,000 people over the age of 65. Of newly
diagnosed patients under the age of 65, about 80 percent of the men
and 70 percent of the women will die within eight years. In people
diagnosed with heart failure, sudden cardiac death occurs at six to
nine times the rate of the general population. The earlier the
condition is diagnosed and treatment begins, the better your
prospects for an improved quality of life down the road.
