Abstract：To investigate the risk factors of ischemia stroke after intracoronary stent implantation in patients with atrial fibrillation (AF) complicated by acute myocardial infarction (AMI). Methods The patients with AF complicated by AMI undergone PCI were chosen from 12 third-level hospitals in Beijing from Dec. 2009 to Jan. 2015 by applying inquiring of electronic medical records. All patients were regularly followed up by using methods of telephone or outpatient service, and then divided into stroke group and non-stroke group according to the follow-up results. The baseline data and past medical history (PMH) were compared and analyzed in 2 groups. The risk factors of ischemia stroke were analyzed by using single-factor and multi-factor analysis. Results There were totally 516 cases included with average follow-up time for (36.8±18.8) d. During the follow-up period, there were 84 cases died, 26 with ischemia stroke and 138 with major adverse cardiovascular events (MACE). The results of Logistic multi-factor analysis showed that grouping of acute coronary syndrome (ACS, OR=4.24, 95%CI: 1.22-14.74, P=0.023) and ratio of left atrioventricular diameter (OR=48.47, 95%CI: 1.15-2039.37, P=0.042) were independent risk factors of ischemia stroke. Conclusion The mortality is higher in patients with AF complicated by AMI, and the risk factors of ischemia stroke are related to ACS grouping and ratio of left atrioventricular diameter.
