| Abstract: | A study of 67 coronary patients with isolated stenosing atherosclerosis of the anterior interventricular branch of the left coronary artery demonstrated proximal arterial stenosis in 2/3 of the cases; it was hemodynamically significant in 83% of those. Clinically, coronary heart disease in this condition was manifested as severe angina pectoris. Fifty-two percent of the patients had a history of myocardial infarction. Long-term conservative treatment, administered in 33 cases, produced an improvement in 67%, and controlled anginal attacks in 20%. Aortocoronary shunting, performed in 34 patients, had a complete antianginal effect in 2/3 of those. Clinical improvement was accompanied with somewhat improved stress tolerance. |
