| Chest pain accompanied by breathlessness, and in some cases with sweating and nausea, is known as angina pectoris.
It usually lasts for about 1 to 5 minute, and is relieved with rest in most of the cases (precipitated by exertion or emotional stress, or, exacerbated by having a full stomach and by cold temperatures). This pain is due to a lack of blood and hence oxygen supply of the heart muscle, when the heart blood vessels are blocked or narrowed with spasm. ECG is usually normal in angina patients who are tested when not feeling any chest pain. Cigarette smoking, diabetes, high cholesterol, high blood pressure, sedentary lifestyle and family history of premature heart disease, are major risks for angina. |
