What is Angina?
Angina is a chest pain or discomfort caused by some fatty deposits or plaque in blood vessels which is responsible for decreased blood flow to the heart muscle. The symptoms are squeezing chest pain, feeling heaviness or pressure which can spread to the arms, neck, shoulders, back & jaw.
Coronary Artery Disease is the most common reason for angina. There is narrowing of one or more coronary arteries which supply blood to the heart muscle. The narrowing is because of increasing cholesterol level or fatty deposits, which causes an obstruction to the supply of blood & oxygen. Angina may also occur because of low hemoglobin.
