Incidence, predictors and impact of stroke on mortality among patients with acute coronary syndromes following percutaneous coronary intervention—Results from the PROMETHEUS registry

Background Stroke represents a potentially calamitous complication among patients with acute coronary syndrome (ACS) undergoing percutaneous intervention (PCI). Data on the distribution of stroke occurrence post‐PCI and its impact on mortality are scarce. Objectives We sought to determine the incide...

Description
Summary:Background Stroke represents a potentially calamitous complication among patients with acute coronary syndrome (ACS) undergoing percutaneous intervention (PCI). Data on the distribution of stroke occurrence post‐PCI and its impact on mortality are scarce. Objectives We sought to determine the incidence, predictors and impact of stroke on mortality in ACS patients undergoing PCI. Methods A total of 19,914 ACS patients underwent PCI in the PROMETHEUS multicenter observational study. We calculated the cumulative stroke incidence at 30 days and 1 year using the Kaplan Meier method. We also compared the distribution of stroke, myocardial infarction (MI), and bleeding across time and evaluated their overlap. Predictors of stroke were identified through multivariable Cox‐regression. Stroke, MI, and bleeding were assessed as time‐updated covariates to estimate how each impacts subsequent mortality. Results We found that 244 patients had a stroke within 1 year, a cumulative incidence of 1.5%. Previous cerebrovascular disease was the strongest predictor for post‐PCI stroke, followed by ST‐elevation MI presentation, hypertension, non‐ST‐elevation MI presentation, smoking, female sex, and age. Mortality risk was significantly higher among those who had a stroke versus those who did not (adjusted HR 4.84, p
