Abstract
Objectives
the echocardiographic indices have not been validated in critically ill population. We investigated the correlation between some echocardiographic and hemodynamics parameters.
Design
Prospective Spontaneous non-interventional observational study.
Setting
Adult cardiothoracic intensive care unit, single center (Royal Brompton Hospital, London UK).
Participants
Consecutive adult patients admitted to cardiothoracic intensive care unit for severe respiratory failure, primary cardio-circulatory 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 main results
117 patients were studied (age 57.2 ± 19; 60.6% male). t-IVT showed an inverse correlation with SV, CO, MAP and CPI (respectively r: -67%; -38%; -45%; -51%). MAPSE exhibited a positive correlation with SV, CO, MAP and CPI (respectively r: 43%; 44%; 34%; 31%). LVEF did not show any correlation. In the multivariate analysis the association of t-IVT and hemodynamics was confirmed for SV, CO, MAP and CPI with the highest partial correlation between t-IVT and MAP (R = -58%).
Conclusions
MAPSE and t-IVT are two reproducible and reliable echocardiographic indices of systolic function and ventricular efficacy associated with hemodynamic variables in cardiothoracic critically ill patients, while LVEF did not show any correlation.
