Explanatory Style and Coronary Heart Disease

ByGregory McClellan Buchanan

Cardiovascular disease is the leading cause of death in the United States (Glass, 1 977) . The disease may be broken down into two components: coronary artery disease (CAD), a condition characterized by lesions of the coronary arteries ; and CHD, which has two major manifestations-angina pectoris (severe, recur­ rent chest pains) and myocardial infarction (Ml; "heart attack"). Angina pectoris results when lesioned coronary arteries occlude the blood supply to the heart, resulting in a lack of oxygen known as anoxia or an ischemic attack. If the occlusion is prolonged or complete , actual necrosis of the heart tissue will occur resulting in permanent damage, and possibly death. This is myocardial infarction.
