本研究对86例脑梗塞病人进行了危险因素的调查。调查项目包括病史、临床检查和实验室检验三个部分。经单因素分析全血比粘度(低切)、高血压、ECG异常、吸烟,超重、眼底动脉硬化、主动脉硬化,血浆比粘度、纤维蛋白元和VWF是脑梗塞的危险指标,其中前5项是经多因素主成份分析证实的主要危险指标。危险因素之间错综复杂的相关关系由多因素相关分析表明。 In this study, 86 patients with cerebral infarction risk factors were investigated. Survey items include medical history, clinical examination and laboratory tests in three parts. Univariate analysis showed that whole blood specific viscosity (low cut), hypertension, abnormal ECG, smoking, overweight, fundus atherosclerosis, aortic sclerosis, plasma specific viscosity, fibrin and VWF were risk indicators of cerebral infarction. Item is the main risk indicator confirmed by multi-factor principal component analysis. The intricate correlation between risk factors was shown by multivariate correlation analysis.
