目的探讨青年脑梗死患者不同年龄组间的病因、危险因素及预后的差异性。方法将115例青年脑梗死患者按年龄分为青少年组(14~28岁)和青壮年组(29~40岁),对其临床资料进行回顾性分析。结果青少年组29例,青壮年组86例;按TOAST分型,106例有病因可循,其中青少年组其他病因型最多,而青壮年组分布较分散(P<0.05);主要危险因素有男性及高血压病、高脂血症、吸烟和酗酒,其中性别和高血压病有组间差异(P<0.01)。结论青年脑梗死多有明确病因,在青少年组与青壮年组间临床分布有差异,如能早发现并做针对性处理则预后较好。 Objective To investigate the differences of etiology, risk factors and prognosis among different age groups in young patients with cerebral infarction.
