本文研究直立性低血压(OH)与症状性闭塞性脑血管病之间的关系。作者对近2周内有一过性脑缺血发作(TIA)的患者80例,分别测定其仰卧(至少3分钟)和站立(3分钟后)时的血压,凡站立较仰卧时收缩压下降20mmHg 以上者,即确定为OH,然后,对有OH 患者的临床特征进行分析,探讨其间的因果关系。结果:80例患者中发现13例OH,其中男7女6,除1例53岁外余均在60岁以上,最大者76岁。全部13例均有短暂、重复、固定型TIA,计颈动脉
This article studies the relationship between orthostatic hypotension (OH) and symptomatic occlusive cerebrovascular disease. The authors of the recent 2 weeks had a transient ischemic attack (TIA) in 80 patients, were measured supine (at least 3 minutes) and standing (3 minutes) when the blood pressure, standing more supine when the systolic blood pressure decreased by 20mmHg Or more, that is, identified as OH, and then analyzed the clinical characteristics of patients with OH, to explore the causal relationship between them. Results: Thirteen cases of OH were found in 80 cases, including 7 males and 6 females. Except 1 case of 53 years old, all were over 60 years old, the largest was 76 years old. All 13 patients had a transient, repeat, fixed TIA, carotid artery
