BackgroundThe management of mechanically ventilated patients depends on a combination of clinical skills and measurement of physiological parameters.ObjectivesWe evaluated the role of mitral annular plane systolic excursion (MAPSE) in the determination of left ventricular systolic function (LVSF) in mechanically ventilated obese patients.MethodsA convenient sample of 60 of 68 obese, mechanically ventilated patients in the intensive care unit were included in the study. Transthoracic echocardiogram MAPSE measurement (averaged from 3 consecutive cycles) on 2 separate days, vs the eyeball ejection fraction (classic clinical method) on 2 separate days, and vs the biplane Simpson (classic research and consultative echocardiogram method) on 2 separate days was obtained. In patients with non sinus rhythm, measurements were collected over 5 to 10 heartbeats.ResultsThere was a significant positive correlation between MAPSE and LVSF assessment using the eyeball method and Simpson method (r= 0.89 and 0.87, respectively; P< .001). Mitral annular plane systolic excursion was significantly shorter in duration (P< .001).ConclusionsMitral annular plane systolic excursion is useful, an easier technique, and shorter in duration compared with the eyeball method in the determination of LVSF in mechanically ventilated obese patients.Copyright © 2016 Elsevier Inc.
