Angina is pain or
discomfort, most often in the chest, that happens when some
region of the heart does not receive enough oxygen from the
blood. It is usually a symptom of coronary artery disease,
which occurs when the vessels that carry blood to the heart
become narrowed and blocked due to atherosclerosis.
Angina can feel like a squeezing pain, pressure, or tightness
usually in the chest under the breastbone, but sometimes in
the shoulders, arms, neck, jaw, or back. Angina is most commonly
felt after physical exertion. It is also triggered by stress,
extreme cold or heat, heavy meals, alcohol, and cigarette
smoking. |
