The symptoms of coronary heart disease will depend on the severity of the disease. Some people with CAD have no symptoms, some have episodes of mild chest pain or angina, and some have more severe chest pain.
If too little oxygenated blood reaches the heart, a person will experience chest pain called angina. When the blood supply is completely cut off, the result is a heart attack, and the heart muscle begins to die. Some people may have a heart attack and never recognize the symptoms. This is called a "silent" heart attack.
Symptoms of coronary artery disease include:
Heaviness, tightness, pressure, or pain in the chest behind the breastbone
Pain spreading to the arms, shoulders, jaw, neck, or back
Shortness of breath
Weakness and fatigue
