Angina, is a temporary pain or discomfort in the chest caused by decreased blood flow to the heart muscle. Due to decreased blood flow, there is not enough oxygen in the heart muscle, resulting in chest pain. One of the most common causes of angina pectoris is coronary artery disease, which can cause narrowing of the coronary arteries that carry blood and oxygen to the heart muscle.

Although angina is not a heart attack, its presence indicates an increased risk of having a heart attack. Seek medical attention immediately if you experience any pain or discomfort in your chest.

There are two main types of angina: stable and unstable. Stable angina pectoris, the most common type, develops during physical activity and generally lasts a short time (about five minutes or less), if physical activity has been completed. Unstable angina is less common and usually occurs during rest periods. Usually, unstable angina lasts longer and symptoms may be more severe.

There are many risk factors associated with angina that include, but are not limited to, high blood pressure, diabetes, obesity, family history, smoking, stress and age.
