Abstract:
Objective To investigate the risk factors of recurrent stroke in IS patients with CHF.Methods A total of 235 elderly IS patients with CHF admitted to Northern Jiangsu People's Hospital from January 2021 to January 2023 were enrolled in this study.According to LVEF clas-sification,they were divided into reduced ejection fraction HF group(HFrEF,LVEF＜40％,80 patients),intermediate ejection fraction HF group(HFmrEF,40％≤LVEF＜50％,57 patients),and preserved ejection fraction HF group(HFpEF,LVEF≥50％,98 patients).After all of them were followed up for 12 months,the patients with recurrent IS were assigned into the recurrent IS group(42 patients)and those without into the non-recurrent IS group(193 patients).Their gener-al data,laboratory results,clinical endpoint events and other indicators were compared in the above groups.Multivariate logistic regression analysis was applied to identify the related risk fac-tors for recurrent stroke in elderly patients with CHF and IS.Results There were significant differences in women ratio,age,history of smoking and drinking,peripheral vascular disease,RBC count,hemoglobin,hematocrit,LDL-C,prothrombin time,international standardized ratio,BNP,LVEF,LVEDD and LVESD among the three groups(P＜0.05,P＜0.01).The recurrent IS group had obviously larger proportion of diabetes mellitus,longer thrombin time,and larger LAD and RAD when compared with the non-recurrent IS group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that diabetes(OR=0.251,95％CI:0.1 96-1.494,P=0.031)and LAD(OR=1.085,95％CI:1.008-1.169,P=0.031)were independent risk factor for recurrent stroke in elderly patients with CHF and IS.There were no significant differences in follow-up period and incidence of clinical endpoints among the three groups(P＞0.05).Conclusion Diabetes and LAD are independent risk factors for recurrent IS in elderly CHF patients with IS.
