摘要
目的：探讨老年人血小板聚集性的变化。方法：采用ＴＹＸＮ－９１智能血小板聚集仪，以２μｍｏｌ／ＬＡＤＰ为诱导剂，分别测定５０例缺血性脑血管疾病、５０例冠心病、５０例健康老年人的血小板聚集性，并与３０例健康年青人相比较，同时比较各老年组治疗前后血小板聚集的变化。结果：缺血性脑血管疾病组、冠心病组及健康老年组的血小板聚集性均增高，说明心脑血管疾病的发生虽与血小板聚集性增高有关，但并非其发病的唯一因素。结论：动态观测血小板聚集性的变化，可以判定药物疗效。在健康老年人中，使用小剂量阿斯匹林可以降低血小板聚集性。
Objective: To study the change of platelet aggregation in aged patients ‘so as to promote clinical treatment. Methods: Platelet aggregation of 50 cerebrovascular disease aged men and 50 coronary heart disease aged men and 50 healthy men of the same age were compared with that of 30 healthy young men. The change of platelet aggregation in each aged men group before and after treatment were also observed. Results: The rate of platelet aggregation increase is presented in each aged men group. It shows a relationship of platelet aggregation increase to blood vessel disease of heard and brain. Our study suggests that platelet aggregation is a better value reflecting the curative effect. Low dose of aspirin can be used to prevent and cure blood vessel disease of heart and brain in the healthy aged men.
