H. Daida et al., COMPARISON OF PEAK EXERCISE OXYGEN-UPTAKE IN MEN VERSUS WOMEN IN CHRONIC HEART-FAILURE SECONDARY TO ISCHEMIC OR IDIOPATHIC DILATED CARDIOMYOPATHY, The American journal of cardiology, 80(1), 1997, pp. 85
Results of exercise testing in 150 patients with chronic heart failure
show that women were characterized by shorter exercise time, peak oxy
gen consumption, and lower peak oxygen pulse than men. There was a 4.1
-ml/kg/min difference in peak oxygen uptake between genders after the
adjustment of age, peak heart rate, respiratory exchange ratio, ejecti
on fraction, and etiology of heart failure.
