Key result
Exercise cardiac index correlated with peak oxygen uptake (r=0.59, P<0.001) and was a significant prognostic indicator of survival (P=0.018) in patients with pulmonary hypertension.

Does right ventricular reserve (exercise cardiac index) predict exercise capacity and survival in patients with pulmonary hypertension?
p-value: p=0.018
Right ventricular reserve, measured by the ability to increase cardiac index during exercise, is a key determinant of exercise capacity and a significant predictor of survival in patients with pulmonary hypertension.
Blumberg et al. (2013) conducted a cohort in Pulmonary hypertension (n=36). Exercise cardiac index was evaluated on Survival (p=0.018). Exercise cardiac index correlated with peak oxygen uptake (r=0.59, P<0.001) and was a significant prognostic indicator of survival (P=0.018) in patients with pulmonary hypertension.
