5 Cardiac Causes of Chest Pain You Probably Didn't Know About

Angina pectoris is recurring chest pain or discomfort caused by decreased blood supply to the heart. It is a common symptom of coronary artery disease. The accumulation of plaque on the inner walls of the coronary arteries restricts blood flow to the heart. Angina occurs when the heart’s need for oxygen exceeds the level of available oxygen. Angina is typically described as squeezing, pressure, heaviness, tightness or pain in the chest. It can feel like someone is standing on your chest. There are two common types of angina, stable and unstable. Stable angina is persistent reoccurring chest pain that usually occurs with exertion. Unstable angina is the most dangerous, occurs without exertion and warns of an impending heart attack.
