JACC Heart FailPublished

  • Retrospective registry cohort study
  • multivariable-adjusted

Authors' conclusion

LPPV is associated with improved outcomes in CS patients on VA-ECLS requiring MV.

Study context

Population
Patients with cardiogenic shock on VA-ECLS and mechanical ventilation, ELSO registry, 2009–2019
Participants
2,226 patients
Exposure
LPPV vs no LPPV
  • LPPVn = 1,904
Outcome
Survival to discharge

Main finding

As reported in the abstract

Adjusted odds ratio

1.69

95% CI 1.21–2.37

P = 0.0021

By group

LPPV vs no-LPPV
adjusted OR 1.69 (95% CI 1.21–2.37); P = 0.0021

Observational data: associations, not effects.

Further findings

Ventilator pressures at 24 h, survivors to discharge vs non-survivors

Median peak inspiratory pressure lower in survivors: 22 vs 24 cm H2O
P < 0.001
Median dynamic driving pressure (DDP) lower in survivors: 14.5 vs 16 cm H2O
P < 0.001
