Abstract

Aims Venoarterial extracorporeal life support (VA ECLS) is a life-saving treatment with a high risk of mortality. Appropriate patient selection is critical for optimal patient outcomes. Acute kidney injury (AKI) is a common risk among VA ECLS patients, and more information is needed to understand how AKI affects the mortality risk of these patients. To do this, we examined acute decompensated heart failure (ADHF) patients supported by VA ECLS and compared their risk of developing AKI to a background population. VA ECLS has become an increasingly important tool to bridge or recover patients with severe ADHF as the primary indication of VA ECLS.

Methods and Results All VA ECLS patients from a single center were included. ADHF patients supported by VA ECLS were compared with the remaining VA ECLS cohort. CATEGORICAL comparisons were made between groups using chi-squared and Fisher's exact tests. A survival analysis was conducted to determine freedom from AKI between the two groups. Predictor variables were tested by multiple logistic regression. Of the 255 patients included in this study, 110 had ADHF as their primary indication for VA ECLS and 145 patients had other VA ECLS indications. The survival analysis showed that patients with ADHF had a decreased risk of developing AKI on the VA ECLS circuit. Multiple logistic regression revealed no predictors in AKI development between groups and no difference in 30-day mortality was observed.

Conclusion Patients supported by VA ECLS are at high risk of mortality and complications. This research demonstrated that medically complex ADHF patients had less chance of developing AKI when compared with other patients supported by VA ECLS. Future research is needed to investigate potential protective mechanisms of VA ECLS support.

Summary

ADHF patients have lower risk of AKI than other populations on VA ECLS but no change in 30-day mortality rate.
