Abstract
ABSTRACT To the Editor.— We think that the incidence of coronary arteriosclerosis as reported in casualties of the Vietnam war by McNamara and his colleagues (216:1185, 1971) as compared to earlier reports from our studies of casualties from the Korean conflict (158:912, 1955) probably reflects a meaningful downward trend. The most recent study utilized postmortem coronary angiography and dissection of coronary arteries in order to demonstrate atherosclerotic plaques and coronary artery narrowing. The earlier study was accomplished solely through the routine anatomical cross-sectioning and longitudinal dissection of the coronary vessels. Both methods of study are reliable but include certain unavoidable artifacts inherent to the postmortem state of the heart.Coronary arteries from Korean conflict battle casualties have been studied by the cross-section and longitudinal methods (Fig 1 through 3). These illustrations have not been in eluded in any of our previous reports. The degree of luminal narrowing is extensive
