Left Ventricular Diastolic Dysfunction in ARDS Patients.

ABSTRACT:

Background

The aim of this study was to evaluate the possible presence of diastolic dysfunction and its possible effects in terms of respiratory mechanics, gas exchange and lung recruitability in mechanically ventilated ARDS.

Methods

Consecutive patients admitted in intensive care unit (ICU) with ARDS were enrolled. Echocardiographic evaluation was acquired at clinical PEEP level. Lung CT-scan was performed at 5 and 45 cmH₂O. In the study, 2 levels of PEEP (5 and 15 cmH₂O) were randomly applied.

Results

A total of 30 patients were enrolled with a mean PaO₂/FiO₂ and a median PEEP of 137 ± 52 and 10 [9-10] cmH₂O, respectively. Of those, 9 patients (30%) had a diastolic dysfunction of grade 1, 2 and 3 in 33%, 45% and
