A Critical Review on Misleading Evidence in Cardiac Arrest Trials—Why Less Complexity Does Not Result in Better Outcomes

Year: 2026

Type: article

Abstract: Over the past two decades, advanced airway management, early coronary angiography, and therapeutic hypothermia have shaped post-out-of-hospital cardiac arrest (OHCA) care. However, recent large randomized trials have challenged these strategies and created substantial uncertainty leading to relevant guideline changes. This review focuses on the trials that ultimately influenced current guideline recommendations by downgrading previous recommendations. We determine how structural limitations may have affected the validity and interpretation of their results. The review critically evaluates the methodological design and execution of those trials. Despite neutral findings from recent randomized trials, use of advanced airway management during resuscitation, coronary angiography in patients with a high likelihood of acute coronary occlusion, and therapeutic hypothermia for comatose OHCA survivors still play a relevant role in post-resuscitation management.
