Angina is a type of chest pain or discomfort that results from insufficient blood flow to the heart muscle, often due to coronary artery disease. It typically feels like pressure, squeezing, fullness, or pain in the center or left side of the chest and may also be accompanied by discomfort in the shoulders, neck, jaw, arms, or back. Angina episodes can be triggered by physical exertion, stress, or other factors that increase the heart's demand for oxygen.
There are two main types of angina: stable and unstable. Stable angina occurs predictably with exertion or stress and usually resolves with rest or medication. Unstable angina, on the other hand, is more unpredictable and can happen at rest, potentially signaling a more severe condition such as a heart attack. If you experience symptoms of angina, it is essential to seek medical attention, as it may require further evaluation and management to prevent serious cardiovascular events.
