Heart disease includes many different problems that affect the heart and blood vessels. Some examples of heart disease are:
-
Arrhythmia. An arrhythmia is a heart rhythm abnormality.
-
Atherosclerosis. Atherosclerosis is a hardening of the arteries.
-
Cardiomyopathy. This condition causes the heart’s muscles to harden or grow weak.
-
Congenital heart defects. Congenital heart defects are heart irregularities that are present at birth.
-
Coronary artery disease (CAD). CAD is caused by the buildup of plaque in the heart’s arteries. It’s sometimes called ischemic heart disease.
-
Heart infections. Heart infections may be caused by bacteria, viruses, or parasites.
Cardiovascular disease may also refer to heart problems that affect blood vessels.
What are the symptoms of heart disease?
Different types of heart disease may result in a variety of different symptoms.
Arrhythmias
Arrhythmias are abnormal heart rhythms. The symptoms you experience may depend on the type of arrhythmia you have — heartbeats that are too fast or too slow. Symptoms of an arrhythmia include:
-
lightheadedness
-
fluttering heart or racing heartbeat
-
slow pulse
-
fainting spells
-
dizziness
-
chest pain
Atherosclerosis
Atherosclerosis reduces blood supply to your extremities. In addition to chest pain and shortness of breath, symptoms of atherosclerosis include:
-
coldness, especially in the limbs
-
numbness, especially in the limbs
-
unusual or unexplained pain
-
weakness in your legs and arms
Congenital heart defects
Congenital heart defects are heart problems that develop when a fetus is growing. Some heart defects are never diagnosed. Others may be found when they cause symptoms, such as:
-
blue-tinged skin
-
swelling of the extremities
-
shortness of breath or difficulty breathing
-
fatigue and low energy
-
irregular heart rhythm
Coronary artery disease (CAD)
CAD is plaque buildup in the arteries that move oxygen-rich blood through the heart and lungs. Symptoms of CAD include:
-
chest pain or discomfort
-
a feeling of pressure or squeezing in the chest
-
shortness of breath
-
nausea
-
feelings of indigestion or gas
Cardiomyopathy
Cardiomyopathy is a disease that causes the muscles of the heart to grow larger and turn rigid, thick, or weak. Symptoms of this condition include:
-
fatigue
-
bloating
-
swollen legs, especially ankles and feet
-
shortness of breath
-
pounding or rapid pulse
Heart infections
The term heart infection may be used to describe conditions such as endocarditis or myocarditis. Symptoms of a heart infection include:
-
chest pain
-
chest congestion or coughing
-
fever
-
chills
-
skin rash
