Do invasive exercise haemodynamic parameters and peak VO2 predict mortality and major events in patients with NYHA class II or III chronic heart failure?
Exercise cardiac power output and non-invasive peak VO2 are strong predictors of short-term prognosis in patients with NYHA class II or III chronic heart failure.
Roul et al. (1995) studied this question.
