老年人血压与腔隙性脑梗塞的关系

对95例经CT证实为腔隙性脑梗塞(CLI)的老年病人的高血压构成比、血压和脉压差频数分布情况、及其病灶面积做了分析和对比研究.结果表明其高血压的构成比为58.95%,说明高血压是老年人CLI的重要病因.其血压和脉压差频数呈正态分布,当老年人收缩压为18.7～24.0kPa或舒张压为11.3～14.0kPa,同时脉压差在8.0～12.0kPa时,有易患CLI的可能;三者在发病中有同等重要的意义.老年人血压与CLI病灶面积之间无直线相关关系,说明老年人血压变化与CLI病灶大小不成正比.

RELATIONSHIP BETWEEN BLOOD PRESSURE AND CEREBRAL LACUNAE INFARCTION IN THE OLD

The hypertension constituent ratio, the frequency distribution of blood pressure and pulse pressure difference, and the lesion areas in 95 aged patients with cerebral lacunae infarction (CLI)proved by CT were compared and analysed. The results showed that the hypertension constituent ratio was 58.95%, which suggested that hypertension might be an important pathogenic factor in CLI in old people. The frequencies of the blood pressure and pulse pressure difference presented a normal distribution, and when the former was between 18.7 and 24.0 kPa and the latter between 8.0 and 12.0 kPa, aged people were susceptible to the disease. The blood pressure and lesion area did not show positive correlation.
