The symptoms of heart failure are related to the changes that occur to your heart and body, and may be mild, moderate, or severe, depending on how weak your heart is. The symptoms can include:
Congested lungs. Fluid backup in the lungs can cause shortness of breath with exercise or difficulty breathing at rest or when lying flat in bed. Lung congestion also causes a dry, hacking cough or wheezing.
Rapid or irregular heartbeats. The heart beats faster to pump enough blood to the body. This causes a fast or irregular heartbeat.
If you have heart failure, you may have one or all of these symptoms or you may have none of them. In addition, your symptoms may not be related to how weak your heart is; you may have many symptoms, but your heart function may be only mildly weakened. Or you may have a more severely damaged heart but have no symptoms.
The symptoms of heart failure can be related to the pooling of fluid in the body or can be secondary to decreased blood flow to the body. Some people with heart failure don't experience symptoms, but here are some of the more common signs:
Shortness of breath with exercise or difficulty breathing at rest or when lying down
Swollen legs, ankles, or abdomen
Dry, hacking cough, or wheezing
Other symptoms may include:
Fatigue, palpitations, or pain during normal activities
If you have any of the above listed symptoms, be sure to see a doctor. Also, because heart failure can occur without symptoms, be sure to get a yearly doctor check-up so that any problems can be detected and treated.
