Abstract:
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 〈 .0001), pulmonary systolic artery pressure (PASP) ( p 〈 .0001), and tricuspid annular (TA) plane systolic excursion (TAPSE) ( p = .036). RV global constructive work (RVGCW) was correlated with RV GLS ( p 〈 .0001) and PASP ( p 〈 .0001). RV global wasted work (RVGWW) was correlated with RV GLS ( p = .008) and TA isovolumetric acceleration (TA IVA) ( p = .008). RV global work efficiency (RVGWE) was correlated with RV GLS ( p 〈 .0001) and tissue Doppler (TD) RV myocardial performance index (TD RMPI) ( p = .043). Conclusion RVMW indices showed good correlations with RV myocardial systolic function.
