SURGICAL METHODS FOR IMPROVING BLOOD SUPPLY TO THE MYOCARDIUM

JAMA. 1954;156(13):1254. doi:10.1001/jama.1954.02950130036012
Abstract

Although many laboratory and clinical studies have been carried out on the mechanisms of blood flow in the normal heart and on the effects of myocardial ischemia, Beck and his associates in 1932 first began to attempt to find surgical methods of improving the blood supply to the heart to compensate for obstruction of coronary arteries.1 Their work is based on a large amount of wellcontrolled experimentation.2 Other investigators are beginning to confirm various aspects of this work, although at first many were skeptical concerning the approach. Now, after a quarter of a century of effort, it has been demonstrated beyond reasonable doubt that it is possible, by surgical methods, to increase collateral circulation to a segment of myocardium made ischemic by occlusion of a major coronary artery. This additional blood makes it possible partially to occlude a major coronary artery with a reduction in mortality as well
