Respiratory failure & ventilation

Systolic Function of the Left Ventricle Assessed by Speckle Tracking in Cardiovascularly Healthy Subjects Is Not Affected by the Initiation of Mechanical Ventilation: Comparison With Conventional Echocardiographic Methods

J Cardiothorac Vasc AnesthPublished Prospective observational study

Authors' conclusion

The initiation of mechanical ventilation in cardiovascularly healthy patients does not significantly alter global left ventricular systolic function, as assessed by speckle tracking.

Study context

Population
Cardiovascularly healthy patients undergoing scheduled surgery under GA, university hospital
Participants
20 patients
Exposure
Before vs after initiation of mechanical ventilation
Outcome
GLS and its six apical four-chamber segments
Methodological detailsbefore-after comparison
  • Before-after comparison

Main finding

As reported in the abstract

  • No significant differences in global longitudinal strain (GLS) after initiation of mechanical ventilation
  • No significant changes in the six individual segments of GLS

Observational data: associations, not effects.

Further findings

LV ejection fraction, LV outflow tract velocity-time integral, E/e' ratio

No significant differences after initiation of mechanical ventilation

Mitral annular plane systolic excursion (MAPSE) and lateral S' wave velocity

Significant differences after initiation of mechanical ventilation; all values remained within normal range
