What is angina pectoris?

Angina pectoris refers to short-lived chest discomfort that arises due to a temporary reduction in blood flow to the heart muscle, typically caused by a blockage in the coronary arteries. This condition is often triggered by physical exertion, stress, or other factors that increase the heart's demand for oxygen. When the heart does not receive adequate oxygenated blood for a brief period, individuals may experience the characteristic chest pain or discomfort associated with angina.

It is important to note that while angina is a symptom that signals the potential for heart disease, it is not the same as a heart attack. A heart attack occurs when there is a complete blockage of blood flow to a part of the heart muscle for a prolonged period, resulting in tissue damage. Additionally, angina pectoris does not refer to conditions affecting the lungs or congestive heart failure. These conditions have distinct pathophysiologies and manifestations that do not overlap with the characteristics of angina pectoris.
