Coronary Occlusion and Coronary Insufficiency

Acute coronary attacks may be divided clinically, electrocardiographically, pathologically and therapeutically into (i) classical angina pectoris, (2) acute coronary insufficiency and (3) acute coronary occlusion. In 1000 consecutive cardiac consultations, 450 of 618 cases with organic heart disease had coronary artery disease. Of these 450 cases, 38 per cent had chronic coronary insufficiency (angina pectoris or congestive failure), 26 per cent had acute coronary insufficiency, and 36 per cent had acute coronary occlusion. The differentiation between coronary occlusion and insufficiency which can be made electrocardiographically in 95 per cent of cases is discussed in this paper.
