影响大动脉粥样硬化性脑梗死复发的危险因素

Objective To explore the risk factors for recurrence of large atherosclerotic cerebral infarction in first-episode patients. Methods The consecutive patients with acute cerebral infarction diagnosed in the Department of Neurology were screened for large atherosclerotic cerebral infarction by CTA/MRAexamination, and all the confirmed patients were followed upfor1year.Thepatientsweredividedintorecurrentischemicstrokegroupandnon-recurrentgroupaccordingtooccurrence of cerebrovascular events during the follow-up. Results A total of 256 eligible patients were included in this study, and all of them completed the follow-up. During the 1-year follow-up, 30 (11.7%) patients had ischemic cerebrovascular stroke events. Univariate analysis showed significant differences in alcohol drinking (P=0.028), smoking (P=0.007), high-density lipoprotein cholesterol (HDL; P=0.045), ischemic heart disease (P=0.002), antihypertensive agents (P=0.036) and statin use (P=0.016) between the recurrent group and non-recurrent group. Cox regression analysis showed that irregular use of statins (RR=0.410, P=0.043), smoking (RR=2.253, P=0.043), HDL (RR=0.327, P=0.029), and ischemic heart disease (RR=8.566, P<0.001) were correlated with recurrent ischemic stroke. Conclusion The first-episode patients with irregular use of statins, low HDL levels, smokingandischemicheartdiseaseareathigherrisksforhavingischemicstrokerecurrence.
