Influence of Positive End-Expiratory Pressure on Myocardial Strain Assessed by Speckle Tracking Echocardiography in Mechanically Ventilated Patients
Purpose. The effects of mechanical ventilation (MV) on speckle tracking echocardiography- (STE-)derived variables are not elucidated. The aim of the study was to evaluate the effects of positive end-expiratory pressure (PEEP) ventilation on 4-chamber longitudinal strain (LS) analysis by STE. Methods. We studied 20 patients admitted to a mixed intensive care unit who required intubation for MV and PEEP titration due to hypoxia. STE was performed at three times: (T1) PEEP = 5cmH2O; (T2) PEEP = 10cmH2O; and (T3) PEEP = 15cmH2O. STE analysis was performed offline using a dedicated software (XStrain MyLab 70 Xvision, Esaote). Results. Left peak atrial-longitudinal strain (LS) was significantly reduced from T1 to T2 and from T2 to T3 (). Right peak atrial-LS and right ventricular-LS showed a significant reduction only at T3 (). Left ventricular-LS did not change significantly during titration of PEEP. Cardiac chambers volumes showed a significant reduction at higher levels of PEEP (). Conclusions. We demonstrated for the first time that incremental PEEP affects myocardial strain values obtained with STE in intubated critically ill patients. Whenever performing STE in mechanically ventilated patients, care must be taken when PEEP is higher than 10cmH2O to avoid misinterpreting data and making erroneous decisions.
