[Left ventricular peak systolic pressure/end-systolic volume ratio change after dobutamine infusion for predicting left ventricular contractile reserve: comparison with Emax].

Abstract

OBJECTIVES Genuine left ventricular contractile function is difficult to assess in the clinical setting. Left ventricular peak systolic pressure/end-systolic volume (Pps/Ves) ratio may be misleading because this index takes no account of the left ventricular end-systolic point and V0 intercept in the pressure-volume relation geographic curve. End-systolic… (More)
