Symptoms

Heart disease symptoms depend on the type of heart disease.

Symptoms of heart disease in the blood vessels

Coronary artery disease is a common heart condition that affects the major blood vessels that supply the heart muscle. Cholesterol deposits (plaques) in the heart arteries are usually the cause of coronary artery disease. The buildup of these plaques is called atherosclerosis (ath-ur-o-skluh-ROE-sis). Atherosclerosis reduces blood flow to the heart and other parts of the body. It can lead to a heart attack, chest pain (angina) or stroke.

Coronary artery disease symptoms may be different for men and women. For instance, men are more likely to have chest pain. Women are more likely to have other symptoms along with chest discomfort, such as shortness of breath, nausea and extreme fatigue.

Symptoms of coronary artery disease can include:

• Chest pain, chest tightness, chest pressure and chest discomfort (angina)
• Shortness of breath
• Pain in the neck, jaw, throat, upper belly area or back
• Pain, numbness, weakness or coldness in the legs or arms if the blood vessels in those body areas are narrowed

You might not be diagnosed with coronary artery disease until you have a heart attack, angina, stroke or heart failure. It’s important to watch for heart symptoms and discuss concerns with your health care provider. Heart (cardiovascular) disease can sometimes be found early with regular health checkups.

Heart disease symptoms caused by irregular heartbeats (heart arrhythmias)

The heart may beat too quickly, too slowly or irregularly. Heart arrhythmia symptoms can include:

• Chest pain or discomfort
• Dizziness
• Fainting (syncope) or near fainting
• Fluttering in the chest
• Lightheadedness
• Racing heartbeat (tachycardia)
• Shortness of breath
• Slow heartbeat (bradycardia)

Heart disease symptoms caused by congenital heart defects

Serious congenital heart defects usually are noticed soon after birth. Congenital heart defect symptoms in children could include:

• Pale gray or blue skin or lips (cyanosis)
• Swelling in the legs, belly area or areas around the eyes
• In an infant, shortness of breath during feedings, leading to poor weight gain

Less-serious congenital heart defects are often not diagnosed until later in childhood or during adulthood. Symptoms of congenital heart defects that usually aren’t immediately life-threatening include:

• Easily getting short of breath during exercise or activity
• Easily tiring during exercise or activity
• Swelling of the hands, ankles or feet
