Protective Effects of Sheng-Mai-San on Right Ventricular Dysfunction during Chronic Intermittent Hypoxia in Mice

Figure 1

Echocardiographic assessment of RV function (). Functional parameters were SV (a), RVFS (b), TV E/A ratio (c), PA-VTI (d), and PA-PEP/PET (e). SMS1 (1.1 g/kg) and SMS2 (5.5 g/kg) prevented the occurrence of RV and pulmonary vascular dysfunction. SV, stroke volume; FS, fractional shortening; TV E/A, tricuspid valve early and late diastolic filling velocities; PA-VTI, pulmonary arterial velocity time integral; PA-PEP/ET, pulmonary arterial preejection time and ejection time. Values are presented as mean ± SEM; versus control, versus control, and versus model.
