Right ventricular echocardiographic parameters and prediction of stroke volume in ischemic cardiogenic shock: A retrospective study
Authors' conclusion
RVOT VTI correlated better (albeit weakly) to and best predicted SV compared to TAPSE, RV S', and TR Vmax in patients admitted to intensive care with CS.
Study context
- Population
- ICU patients with ischemic cardiogenic shock34 months

Main finding
As reported in the abstract
Correlation with SV
RVOT VTI correlated best to SV
r = 0.39 p = 0.01
Tricuspid annular plane systolic excursion (TAPSE) correlation to SV
r = 0.26 p = 0.01
RV S' correlation to SV
r = 0.15 p = 0.21
TR Vmax correlation to SV
r = 0.03 p = 0.78
Observational data: associations, not effects.
