Angina is a common type of chest pain caused by coronary artery disease. Unstable angina can be a warning sign of a heart attack.
Heart disease, usually thought of as blockages in the arteries that can cause a heart attack, can describe any medical condition affecting your heart.
Myocardial ischemia is a heart problem that occurs when blood flow to your heart muscle is decreased, reducing the heart's oxygen supply.
If you have symptoms of heart disease, but your doctor doesn't see any blocked major arteries, small vessel disease may be the cause.
Sudden cardiac arrest is a medical emergency. Rapid treatment improves your chances of survival.
