Patients with angina pectoris demonstrated a significantly lower cardiac index (4.01 vs 5.02 L/min/m2) and stroke index (40.2 vs 53.4 ml/m2) during submaximal exercise compared to clinically normal middle-aged men.

How do hemodynamic responses to exercise differ between clinically normal middle-aged men and those with angina pectoris?
This study aims to characterize the hemodynamic responses to exercise in middle-aged men with and without angina pectoris.
Absolute Event Rate: 4.01% vs 5.02%
p-value: p=<0.01
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.
Foster et al. (Tue,) conducted a cross-sectional in Angina Pectoris (n=30). Angina pectoris vs. Clinically normal middle-aged men was evaluated on Cardiac index during first level of exercise (L/min/m2) (p=<0.01). Patients with angina pectoris demonstrated a significantly lower cardiac index (4.01 vs 5.02 L/min/m2) and stroke index (40.2 vs 53.4 ml/m2) during submaximal exercise compared to clinically normal middle-aged men.
