What are the signs and symptoms of coronary artery disease?
A common symptom of coronary artery disease (CAD) is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn’t get enough oxygen-rich blood. Angina may feel like pressure or a squeezing pain in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back. This pain tends to get worse with activity and go away when you rest. Emotional stress also can trigger the pain. Another common symptom of CAD is shortness of breath. This symptom happens if CAD causes heart failure. When you have heart failure, your heart can’t pump enough blood throughout your body. Fluid builds up in your lungs, making it hard to breathe. The severity of these symptoms varies. The symptoms may get more severe as the buildup of plaque continues to narrow the coronary arteries.
