Comparison of peak exercise oxygen uptake in men versus women in chronic heart failure secondary to ischemic or idiopathic dilated cardiomyopathy

In summary, women with chronic heart failure were characterized by shorter exercise time, peak V̇O2, and lower peak oxygen pulse than men with heart failure. There was a 4.1-ml/kg/min difference in peak V̇O2 between genders after the adjustment of age, peak heart rate, respiratory exchange ratio, ejection fraction, and etiology of heart failure.
