Association Between Right Ventricular Systolic Parameters Measured by Echocardiography and Stroke Volume Derived From Pulmonary Artery Catheter in Ischemic Cardiogenic Shock

J Cardiothorac Vasc AnesthPublished Prospective observational cohort study

Authors' conclusion

RVOT VTI is the echocardiographic RV systolic function parameter that best correlates with PAC-derived native SV in patients with STEMI complicated by CS.

Study context

Population
Patients with ST elevation myocardial infarction (STEMI) complicated by cardiogenic shock admitted to a tertiary cardiac ICU in London, UK
Participants
43 patients
Exposure
Seven echocardiographic right ventricular (RV) systolic function parameters vs pulmonary artery catheter (PAC)-derived stroke volume
Outcome
Correlation with PAC-derived stroke volume
