Abstract: Objective To analyze the recurrence risk factors of aged patients with minor ischemic stroke under standardized secondary prevention. Methods Patients over 80 years old and with minor ischemic stroke history were enrolled, and the following data were collected: demographic characteristics, medical history, current medicine, blood test, imaging findings and recurrence of ischemic strokes. Patients were divided into two groups: the recurrence group and the non-recurrence group. Chi-square test,logistic regression models were performed to assess correlations between baseline variables and recurrence of minor stroke events. Results In our study, 26 patients had recurrent minor ischemic stroke(32.5%). The prevalence of recurrence of minor stroke was positively correlated with hypertension(CI 0.265, P 0.018), SBP(CI 0.232,P 0.038), d-2-dimer(CI 0.232,P 0.048). Patients in recurrence group are more likely to presented with SBP elevation compared to non-recurrence group(χ²=6.919, P=0.031). Unconditional logistic regression analysis showed that hypertension, especially high SBP significantly related to minor ischemic stroke recurrence. Conclusion Hypertension,especially elevated SBP, were considered as an independent risk factors for aged old patients with minor ischemic stroke who received standardized secondary prevention.
