Percutaneous Coronary Intervention (PCI) Post Out-of-Hospital Cardiac Arrest: A Narrative Review.

Cardiovascular disease is a leading cause of mortality worldwide; therefore, preventing death and improving patient outcomes are a priority. Increasing numbers of patients are surviving hospital admissions after an out-of-hospital cardiac arrest (OHCA). An OHCA has a poor prognosis, and myocardial infarctions (MIs) are the most common cause; hence, the use of emergency coronary angiography and percutaneous coronary intervention (PCI) is an important tool in trying to improve survival. This narrative review explores the role of PCI in OHCA management; understanding angiography findings in OHCA patients offers critical insights into underlying coronary artery disease burden, informing the necessity for PCI. Also, looking at specific subgroups, like females, is essential for equitable intervention access and outcome optimization. Understanding the role of support devices such as Impella and extracorporeal membrane oxygenation (ECMO), which show promise in enhancing outcomes by providing hemodynamic support during PCI and improved overall survival, is linked to better neurological outcomes, highlighting the significance of timely PCI and comprehensive post-PCI care.
