马面鱼油与鱼肉对老年高血压患者的影响

Blood Pressure-lowering Effects of Mackeral and its Concentrated Oil Diet on Older Patients with Mild Essential Hypertension

摘要: 老年高血压病人40例分2组，每天饮食分别补充一定量的马面鱼油或鱼肉。1个月后2组血压与试验前相比均显著下降（P＜0．01），鱼油组降压有效率为9091％，鱼肉组为88．88％，两组之间比较无显著差异（P＞0．05）。2组的血清甘油三酯亦有显著下降。本结果表明，富含二十碳五烯酸（匹A）及二十二碳六烯酸（DHA）的马面鱼油及鱼肉对老年轻型高血压病人具有明显的降血压作用。

Abstract: This study was designed to observe the effects of mackeral and its concentrated oil diet on 40 older patients with mild essential hypertension. It was found that the blood pressure was lowered in 90. 19% patients by dietary fish oil,88. 88% patients by dietary mackeral. There was no significant difference in blood pressure-lowering effect between these two groups （P ＞ 0. 05 ）. The serum triglyceride was decreased significantly after 1 month mackeral diet （P＜0. 01 ） or its oil diet （P＜0. 05）. The results showed that mackeral or its rich eicosapentaenoic acid （EPA） and docosahexaenoic acid （DHA）oil could lower the blood pressure in older patients with mild hyperten sion.
