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 < .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.
背景
右心室（RV）心肌做功（RVMW）是评估 RV 功能的最新方法。迄今为止，尚未研究 RVMW 指数与 RV 收缩和舒张功能之间的相关性。
方法
共前瞻性纳入 106 名健康志愿者（中位数年龄 34 岁，46%为男性）。使用特定软件通过 RV 压力-应变环测量 RVMW 指数。分析 RVMW 指数与其他 RV 功能之间的相关性。
结果
在多元分析中，RV 整体做功指数（RVGWI）与 RV 整体纵向应变（RV GLS）（p < .0001）、肺动脉收缩压（PASP）（p < .0001）和三尖瓣环平面收缩期位移（TAPSE）（p = .036）显著相关。RV 整体有效功（RVGCW）与 RV GLS（p < .0001）和 PASP（p < .0001）相关。RV 整体无效功（RVGWW）与 RV GLS（p = .008）和三尖瓣等容加速度（TA IVA）（p = .008）相关。RV 整体工作效率（RVGWE）与 RV GLS（p < .0001）和组织多普勒（TD）RV 心肌运动指数（TD RMPI）（p = .043）相关。
结论
RVMW 指数与 RV 心肌收缩功能相关性良好。
