ABSTRACT
OBJECTIVES:
The echocardiographic indices have not been validated in critically ill population. The authors investigated the correlation between some echocardiographic and hemodynamic parameters.DESIGN:
Prospective, spontaneous, noninterventional observational study.SETTING:
Adult cardiothoracic intensive care unit, single center (Royal Brompton Hospital, London, United Kingdom).PARTICIPANTS:
Consecutive adult patients admitted to the cardiothoracic intensive care unit for severe respiratory failure, primary cardiocirculatory failure, and post-aortic surgery.INTERVENTIONS:
Clinical hemodynamic parameters (stroke volume [SV], cardiac output [CO], mean arterial pressure [MAP], and cardiac power index [CPI]) and echocardiographic indices of ventricular function (left ventricular total isovolumic time [t-IVT], mitral annular plane systolic excursion [MAPSE], and left ventricular fraction [LVEF]) were evaluated offline. MEASUREMENTS AND MAINRESULTS:
The study comprised 117 patients (age 57.2 ± 19; 60.6% male). The t-IVT showed an inverse correlation with SV, CO, MAP, and CPI (r -67%; -38%; -45%; -51%, respectively). MAPSE exhibited a positive correlation with SV, CO, MAP, and CPI (r 43%; 44%; 34%; 31%, respectively). LVEF did not show any correlation. In the multivariate analysis the association between t-IVT and hemodynamics was confirmed for SV, CO, MAP, and CPI, with the highest partial correlation between t-IVT and MAP (Râ¯=â¯-58%).CONCLUSIONS:
MAPSE and t-IVT are 2 reproducible and reliable echocardiographic indices of systolic function and ventricular efficacy associated with hemodynamic variables in cardiothoracic critically ill patients, whereas LVEF did not show any correlation.Palavras-chave
