  • Registry-based cohort study
  • multicentre

Authors' conclusion

This multicentre European study shows that LV recovery mostly occurs within the first year after LVAD implantation and is associated with better clinical outcomes.

Study context

Population
Patients with a durable left ventricular assist device (LVAD) with left ventricular ejection fraction (LVEF) measured at baseline and after implantation (EUROMACS registry)
Participants
1,550 patients
Exposure
No recovery vs Mild vs Intermediate vs Full
Outcome
Prevalence, predictors and clinical impact of LV recovery after LVAD implantation

Main finding

As reported in the abstract

Marginal probability of LV recovery category · 4 years

Observational data: associations, not effects.
