Two-Dimensional-Strain Echocardiography in Intensive Care Unit Patients: ă A Prospective, Observational Study

Résumé

Purpose. Two-dimensional-strain echocardiography (2D-strain) is a ă promising technique for the early detection of myocardial dysfunction. ă Our study was aimed to assess its feasibility in the intensive care unit ă (ICU). Our secondary goal was to determine if 2D-strain could predict ă the patient's outcome. ă Methods. Conventional echocardiography and 2D-strain were performed on ă 64 consecutive patients admitted to our ICU. Using 2D-strain, the ă longitudinal deformation of the left ventricle was assessed. Feasibility ă of 2D-strain, diagnosis performance, and 28-day mortality prediction ă were determined. ă Results. 2D-strain measurements could be performed in 77% of our ă patients. All 2D-strain variables related to ventricular performance ă were significantly impaired in the patients who died compared with those ă who survived. Strain global medium was the only independent ă echocardiographic variable predictor of 28-day mortality rate (odds ă ratio 0.60; 95% confidence interval 0.43-0.80, p = 0.002). ă Conclusions. 2D-strain measurement is feasible in ICU patients, enabling ă identifying early left ventricle dysfunction. Strain global medium is an ă independent predictor of 28-day mortality. (C) 2016 Wiley Periodicals, ă Inc.
