Back to the flow: a comprehensive systematic review and meta-analysis of epinephrine in the treatment of no-reflow

Key Points

This work aims to evaluate the effectiveness of epinephrine in treating no-reflow phenomena during coronary procedures.
Conducted a systematic review and meta-analysis of studies related to epinephrine and no-reflow.
Included studies that reported on the success rates of intracoronary epinephrine compared to adenosine.
Analyzed the variability and limitations in existing evidence regarding the therapeutic benefits.
Epinephrine showed better success rates in primary no-reflow interventions.
Findings indicated earlier interventions led to reduced microvascular damage.
Epinephrine has a modest advantage over adenosine but requires further research due to limited data.

Abstract

Therefore, intracoronary epinephrine was associated with encouraging but exploratory findings, and the higher success rate in primary no-reflow may reflect earlier intervention and less severe microvascular damage. Its modest advantage over adenosine suggests potential therapeutic value, though evidence remains limited and heterogeneous.
