BACKGROUND

Up to 70% of out-of-hospital cardiac arrest (OHCA) patients have a relevant coronary stenosis which may need revascularization. The short- and long-term ischemic and bleeding risk of unconscious and conscious OHCA patients undergoing percutaneous coronary intervention (PCI) is largely unknown.

OBJECTIVES

This study sought to compare the occurrence of 1-year outcomes after PCI between OHCA patients, stratified on the basis of state of consciousness, with patients with acute coronary syndrome (ACS) not preceded by OHCA.

METHODS

The study assessed the unadjusted and adjusted risk of cardiovascular events in a prospective single-center cohort of 9,303 consecutive PCI patients.

RESULTS

At 1 year, all-cause mortality was higher in unconscious (49.5%) but not in conscious OHCA (8.9%) patients than in ACS patients (8.0%), and both unconscious and conscious OHCA patients were more likely than ACS patients to experience definite stent thrombosis (4.4% and 3.5% vs 1.3%) and Bleeding Academic Research Consortium 3 or 5 bleeding (17.8% and 9.0% vs 5.1%). The higher hazards were largely determined by events occurring in the first 30 days. After multivariable adjustment, only unconscious OHCA patients remained at increased risk of death (adjusted HR: 3.27; 95% CI: 2.65-4.05), definite stent thrombosis (adjusted HR: 2.40; 95% CI: 1.30-4.43), and Bleeding Academic Research Consortium 3 or 5 bleeding (adjusted HR: 2.51; 95% CI: 1.82-3.47) at 1 year.

CONCLUSIONS

At 1 year after PCI, unconscious OHCA patients were at higher risk of death, definite stent thrombosis, and bleeding, while conscious OHCA patients had similar hazards compared with an all-comer ACS population without OHCA. Dedicated PCI strategies for OHCA patients taking into account their state of consciousness after resuscitation are warranted.
