The most common symptoms of coronary artery disease are angina (say "ANN-juh-nuh" or "ann-JY-nuh") and shortness of breath when exercising or doing other vigorous activity. Women are somewhat more likely than men to have other symptoms like nausea and back or jaw pain.
- Stable angina has a typical pattern. You can likely predict when it will happen. It happens when your heart is working harder and needs more oxygen, such as during exercise. Symptoms go away when you rest or take nitroglycerin.
- Unstable angina is a change in your usual pattern of stable angina. It is an emergency. It may mean that you are having a heart attack.
