O N Angina is a pain or cramplike sensation in the chest that occurs when the heart muscle can't get the oxygen it needs.
Healthy arteries expand to accommodate increased blood flow when the heart needs more oxygen.
Increased physical exertion, emotional distress or exposure to extreme temperatures can trigger episodes of angina. S K Angina occurs more often in people over age 30, and the prevalence increases with age. It is also more common in men than in women. Since angina is an indication of underlying coronary artery disease, the factors that lead to the narrowing of the arteries also increase the risk of angina. These factors include high blood cholesterol, high blood pressure, smoking, obesity and a family history of heart disease.
