Angina Pectoris
1
The word ‘angina’ is used to describe the pain or discomfort of cardiac origin which results due to temporary ischemia of the myocardium. It is characterized by a discomfort of cardiac origin resulting due to temporary ischemia of the myocardium. The myocardial ischemia results due to deficiency of oxygen during increased metabolic activities. The increased demand for oxygen cannot be fulfilled due to coronary vessel constriction. The primary cause o angina is supposed to e atherosclerosis of large coronary arteries. This may lead to reflex vasospasm of coronary arteries that result into sudden, severe substernal pain which often radiates to the left shoulder and along the flexor surface of the left arm. It occurs commonly with exertion or emotional stress. The duration of angina episode may vary from 30 secs to 30 mins and may be relieved by rest or nitroglycerin. Hypertension and cigarette smoking are amongst the principle etiologies of angina pectoris.
