Abstract
The vast bulk, of coronary disease encountered clinically is on an arteriosclerotic background. Now arteriosclerosis is a progressive situation. Accordingly, coronary disease, too—as a rule—is progressive and passes through various stages or degrees, to wit: The average human being first sustains his “angina of effort.” Later, sometimes years later, he develops an acute occlusion with massive infarction. As he grows older, his pathology leads him clinically into the third phase, “chronic coronary insufficiency.” Due to earlier diagnosis and more adequate management, the outlook for these individuals is increasingly good.
