50岁以下脑梗塞的病因和远期预后

The cause and long-term prognosis of cerebral infarction in the people under 50 years

本文报告的100例50岁以下脑梗塞中,早发性动脉硬化为最常见病因(44%)。其次为器质性心脏病(29%);左房粘液瘤、潜在心肌病、纤维肌发育不全,Moyamoya病,Takayasu 大动脉炎等虽相对较为少见,但却为值得重视的原因。感染性血管病、偏头痛、口服避孕药和病因不明的病例都较文献报告为低。平均36.8个月的随访结果表明,心源性脑梗塞的死亡率最高;早发动脉硬化和器质性心脏病是复发的主要原发疾病;无复发存活病例中,多数预后较好。

One hundred cases of cerebral infarction under the age of 50, admmitted over the last 10 years. are analized and the two common causes are premature arteriosclerosis (44%) and structural heart diseases with arrhythmia or heart failure (29%); left atrial myxoma, occult cardiopathy, fibromuseular dyslasia, moyamoya disease. Takayasu arteritis and the like are the less common but important causes for clinical practice. As a cause of cerebral infaretion, infective disease, migraine or oral controceptive is less frequent than that reported in the literatures. The average of 36.8 month's follow up study showed that the higher frequency of death rate and recurrence are within the subgroup of cardiac origin, and the majority cases without relapse after the initial event have better prognosis.
