Key result
Invasive coronary angiography and percutaneous coronary intervention are fundamental in managing out-of-hospital cardiac arrest, a condition with up to 90% mortality in most countries.
Why the study?
Recent RCT evidence challenges routine early CAG in NSTEMI post-OHCA, and resuscitated patients face elevated thrombotic and bleeding risks, necessitating tailored invasive and antithrombotic strategies.
Recent evidence challenges the routine use of early coronary angiography in OHCA patients with NSTEMI, highlighting the need for tailored invasive and antithrombotic strategies due to high bleeding and thrombotic risks.
May warrant selective CAG timing in NSTEMI after OHCA; leaves open optimal antithrombotic strategies in this high-risk population.
Out-of-hospital cardiac arrest (OHCA) continues to be a major global cause of death, affecting approximately 67 to 170 per 100,000 inhabitants annually in Europe, with a persisting high rate of mortality of up to 90% in most countries. Acute coronary syndrome (ACS) represents one of the most significant cause of cardiac arrest, and therefore invasive coronary angiography (CAG) with subsequent percutaneous coronary intervention (PCI) has emerged as a fundamental component in the management of OHCA patients. Recent evidence from large randomized controlled trials (RCTs) challenges the routine use of early CAG in the larger subgroup of patients with non-ST segment elevation myocardial infarction (NSTEMI). Additionally, emerging data suggest that individuals resuscitated from OHCA related to ACS face an elevated risk of thrombotic and bleeding events. Thus, specific invasive coronary strategies and anti-thrombotic therapies tailored to this unique setting of OHCA need to be considered for optimal in-hospital management. We sought to provide an overview of the prevalence and complexity of coronary artery disease observed in this specific population, discuss the rationale and timing for CAG after return of spontaneous circulation (ROSC), summarize invasive coronary strategies, and examine recent findings on antithrombotic therapies in the setting of ACS complicated by OHCA. By synthesizing the existing knowledge, this review aims to contribute to the understanding and optimization of care for OHCA patients to improve outcomes in this challenging clinical scenario.

Gall et al. (2023) conducted a review in Out-of-hospital cardiac arrest related to acute coronary syndrome. Percutaneous coronary intervention and early coronary angiography was evaluated. Invasive coronary angiography and percutaneous coronary intervention are fundamental in managing out-of-hospital cardiac arrest, a condition with up to 90% mortality in most countries.
