Currently, the majority of stroke patients are ischemic stroke patients. It is necessary to evaluate risk factors to prevent ischemic stroke. Data and Methods: The risk factors for stroke in the previous fiscal year were analyzed. They were divided into nonmodifiable and modifiable factors. The probit and ordered probit models were used in the study, with 59341 and 50542 observations used in the estimation of the models, respectively. Results: Among the nonmodifiable factors, age, gender and cerebrovascular disease history are important risk factors. The history of cerebrovascular diseases is considered to be an especially important factor. Among the modifiable factors, taking antihypertensive drugs and recent large weight change are negative risk factors;however, sleeping well significantly reduces the probability of ischemic stroke. Conclusion: It is very important to ensure that medical personnel know a patient’s history of cerebrovascular diseases for proper treatments. Ischemic stroke might be considered an important side effect of antihypertensive drugs. Limitations: The dataset was observatory. There are various types of antihypertension drugs, and their effects are not analyzed.展开更多

文摘目的目前关于脑卒中后认知功能障碍(post stroke cognitive impairment,PSCI)预后的研究较少,尤其是关于接受结构化认知康复治疗但预后无显著改善患者的脑血管病危险因素尚未有报道。本研究旨在探讨影响认知康复治疗应用效果的脑血管病危险因素,为临床实践提供依据。方法对149例缺血性脑卒中患者[年龄(63.60±9.66)岁,男性64.4%]进行为期8周的非药物结构化认知康复治疗,并收集纵向的预后数据。采用蒙特利尔认知评估量表(Montreal cognitive assessment,MoCA)和痴呆生活质量量表(dementia-quality of life instrument,DemQOL)在基线、治疗结束时和治疗结束后6个月进行整体认知功能和生活质量评估。最后通过回归分析评估结构化认知康复治疗对卒中后认知功能障碍预后的影响。结果卒中发作次数更多的患者在接受结构化认知康复治疗结束时MoCA评分提高不明显(OR=2.17,95%CI:0.98~4.81,P=0.056)。与基线相比,脑白质高信号程度越严重的患者在接受结构化认知康复治疗结束时MoCA评分提高越不明显(OR=2.13,95%CI:1.04~4.38,P=0.039)。存在深部微出血的患者在接受认知康复治疗后6个月MoCA评分改善不明显(OR=19.93,95%CI:1.04~384,P=0.047)。结论卒中发作次数、脑白质高信号程度和深部微出血等脑血管病危险因素影响认知康复治疗的预后。然而,这些发现仍需进一步研究验证,且可指导未来临床试验的设计。
