Influence of Culprit Lesion Intervention on Outcomes in Infarct-Related Cardiogenic Shock With Cardiac Arrest

Cardiac arrest (CA) is common in patients with infarct-related cardiogenic shock (CS). The goal of this study was to identify the characteristics and outcomes of culprit lesion percutaneous coronary intervention (PCI) of patients with infarct-related CS stratified according to CA in the CULPRIT-SHOCK (Culprit Lesion Only PCI Versus Multivessel PCI in Cardiogenic Shock) randomized trial and registry. Patients with CS with and without CA from the CULPRIT-SHOCK study were analyzed. All-cause death or severe renal failure leading to renal replacement therapy within 30 days and 1-year death were assessed. Among 1,015 patients, 550 (54.2%) had CA. Patients with CA were younger, more frequently male, had lower rates of peripheral artery disease, a glomerular filtration rate
