Analysis of influencing factors of early poor prognosis in elderly patients with transient ischemic attack / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To analyze the clinical characteristics that affect the early outcomes of the elderly patients with transient ischemic attack(TIA) and provide the guidance for the prediction of disease recurrence.Methods:From January 2016 to December 2019, 315 TIA patients over 60 years old based on the time-clinical definition who were admitted to the department of neurology in Beijing Shijitan Hospital were divided into recurrence cerebrovascular events group(RCVEs group) and non-recurrence cerebrovascular events group(non-RCVEs group) according to the recurrence at 1 month after onset. The clinical characteristics of the two groups were compared by Logsitic regression analysis.Results:There were 29 cases in the RCVEs group and 286 cases in the non-RCVEs group. Compared to the non-RCVEs group, patients in RCVEs group were more likely have higher prevalence of hypertension history(14/15, 83/203), moderate or severe intracranial artery stenosis(21/8, 132/154), carotid stenosis(22/7, 107/179), DWI positive, motor symptoms, carotid artery stenting and higher times of TIA episodes(2(2, 3), 2(1, 2)), fasting blood glucose and glycosylated hemoglobin levels(8.86(8.17, 9.56)mmol/L, 5.82(5.27, 6.33)mmol/L). Logistic regression analysis showed that patients in RCVEs group had a DWI positive( B=1.634, OR=5.124, 95% CI 2.898-9.059, P=0.000) and higher prevalence of moderate to severe stenosis of carotid artery( B=0.572, OR=1.773, 95% CI 1.050-2.993, P=0.032). Conclusion:DWI positive and moderate to severe carotid stenosis may influence the early poor prognosis in patients with TIA.
