    Stable angina is a type of chest pain that occurs when there is not enough blood flow to the heart muscle. This condition is typically caused by coronary artery disease (CAD), which is a condition where the coronary arteries become narrowed or blocked. The narrowing or blockage is often due to atherosclerosis, a process in which plaque builds up inside the arteries. This plaque is made up of fat, cholesterol, calcium, and other substances in the blood. Over time, this plaque hardens and can significantly reduce the blood flow through the arteries. When the heart muscle does not receive enough oxygen-rich blood, it can cause angina. This is often triggered by physical exertion, emotional stress, exposure to cold temperatures, or after eating a large meal, as these activities increase the heart's demand for oxygen. read more >>
