title: Impact of Previous Stroke on Short-Term Myocardial Reinfarction in Patients With Acute ST Segment Elevation Myocardial Infarction: An Observational Multicenter Study.
abstract: Myocardial reinfarction is frequent after ST-elevation myocardial infarction (STEMI). The incidence of previous stroke in STEMI patients is also high. We aim to evaluate the risk factors for short-term myocardial reinfarction in STEMI patients in a multicenter study.STEMI patients with chest pain onset within 12 hours in 247 hospitals in China were enrolled. Seven and 30-day follow-ups from admission to hospitals were performed. The primary outcome of our study was myocardial reinfarction at 30 days after STEMI. The study population was stratified into 2 groups: STEMI patients with mayocardial reinfarction and without mayocardial reinfarction. Survival curve was constructed using Kaplan-Meier survival methods with log-rank statistics. Multivariable Cox regression model was performed to determine the risk factors for myocardial reinfarction events in STEMI patients.A total of 6876 STEMI patients were enrolled. The proportion of STEMI patients with previous stroke was 9.4%. Rate of 30-day myocardial reinfarction was 2.0% among all STEMI patients. Rate of 30-day myocardial reinfarction was 4.2% in STEMI patients with previous stroke which was statistically higher than that in STEMI patients without previous stroke (P < 0.001). Multivariable Cox regression analysis showed that previous stroke (HR, 3.673; 95% CI, 1.180-11.43) and statin use (HR, 0.230; 95% CI, 0.080-0.664) were independent predictors for 30-day myocardial reinfarction.A large proportion of STEMI patients had previous stroke history. Short-term myocardial reinfarction after STEMI is not infrequent. STEMI patients with previous stroke confronted higher rates of short-term myocardial reinfarction and statin could decline the risk of short-term myocardial reinfarction.
