showed a trendP =0.06
Among those at low risk of PAWP elevation, exercise PVP indexed to peak V o 2 showed a trend for predicting exercise PVRI (β=0.32 WU·m 2 per mm Hg/100 mL per min [95% CI, 0.00–0.64]; P =0.06), whereas it was not in those at high risk (β=−0.43 WU·m 2 per mm Hg/100 mL per min [95% CI, −1.03 to 1.67]; P =0.13). ΔPVP with exercise indexed to peak V o 2 was also associated with ΔPVRI (β=0.91
