Correlations among noninvasive right ventricular myocardial work indices and the main parameters of systolic and diastolic functions

Abstract

Background: Right ventricular (RV) myocardial work (RVMW) is the latest method used to assess RV function. To date, correlations among RVMW indices and RV systolic and diastolic functions have not been studied. Methods: A total of 106 healthy volunteers (median age, 34 years; 46% male) were prospectively enrolled. RVMW indices were measured using the RV pressure–strain loop using specific software. The correlations among RVMW indices and other RV functions were analyzed. Results: During the multivariate analysis, the RV global work index (RVGWI) was significantly correlated with RV global longitudinal strain (RV GLS) (p
