Right Ventricular Myocardial Work Characterization in Patients With Pulmonary Hypertension and Relation to Invasive Hemodynamic Parameters and Outcomes

Abstract

Noninvasive evaluation of indexes of right ventricular (RV) myocardial work (RVMW) derived from RV pressure-strain loops may provide novel insights into RV function in precapillary pulmonary hypertension. This study was designed to evaluate the association between the indexes of RVMW and invasive parameters of right heart catheterization and all-cause mortality. Noninvasive analysis of RVMW was completed in 51 patients (mean age 58.1 ± 12.7 years, 31% men) with group I or group IV pulmonary hypertension. RV global work index (RVGWI), RV global constructive work (RVGCW), RV global wasted work (RVGWW), and RV global work efficiency (RVGWE) were compared with parameters derived invasively during right heart catheterization. Patients were followed-up for the occurrence of all-cause death. and were and with parameters of RV and with invasively derived RV work index and derived pulmonary with and RV global to and to were with all-cause RV global and were indexes of RVMW were with invasively derived RV work index and parameters of RV of and were with all-cause parameters of RV function were Noninvasive evaluation of indexes of right ventricular (RV) myocardial work (RVMW) derived from RV pressure-strain loops may provide novel insights into RV function in precapillary pulmonary hypertension.
