Coronary artery disease may have no symptoms. When there are symptoms, the most common one is chest pain, called angina. The symptoms of angina may include pain in the chest that lasts for more than 2 minutes, or that goes away and comes back. It can feel like pressure, squeezing, fullness, or pain. There may be pain in other areas of the upper body, such as in one or both arms, the back, neck, jaw, or stomach. You may also be short of breath, break out in a cold sweat, or feel lightheaded or sick to your stomach.

Angina tends to happen with activity, after a heavy meal, or with emotional stress. However, angina may also happen when you are resting. The pain happens more in cold weather.
