Hemodynamic Responses to Exercise in Clinically Normal Middle-aged Men and in Those with Angina Pectoris *

Abstract

The effects of aging on the hemodynamic re- sponses to exercise in men are at present poorly understood. Although a number of studies in- vestigating these responses in young people have been reported, relatively few have been carried out in subjects older than 35 years. Granath, Jonsson, and Strandell (2) have described the re- sults of exercise upon cardiac output and vascular pressures in a group of elderly normal men. More recently Levine and his associates (3) and Weissler, Peeler, and Roehll (4) have published data on normal subjects (as well as those with heart disease) that have included several in the middle years of life.
