Correlation of the extent and severity of atherosclerosis in the coronary and cerebral arteries.

INTERRACIALI, geographic, and sex differences in the incidence of coronary heart disease and cerebrovascular accidents in various parts of the world have aroused great interest in the study of atherosclerosis of the coronary and cerebral arteries. The extent and severity of atherosclerosis of these vessels vary in different countries." 2 It is likely that the degree of correlation between atherosclerosis of one vascular bed and another, as also between their different branches, may vary from region to region, accounting for the differential behavior in the clinical consequences of coronary and cerebral atherosclerosis in different populations. The present study is an attempt to see if there are comparable differences in the extent and severity of atherosclerosis between the coronary and the cerebral arterial beds and their different branches.
