伴缺血性心脑血管病变的高血压患者血小板活化的表达

目的　观察伴缺血性心脑血管病变的高血压病人血小板活化的改变 ,探讨其在血栓性疾病发生中的价值。方法　用流式细胞术测定 4 0例伴缺血性心脑血管病变高血压病人及 4 6例无缺血性血管病变高血压病人血小板活化指标CD6 2p、CD6 3的改变 ,两组间进行比较并分别与 30例健康对照组进行比较。同时测定血浆纤维蛋白原浓度。结果　CD6 2 p、CD6 3:两组高血压病人均显著高于正常对照组 (P <0 0 5～ 0 0 1) ,伴血管病变高血压组显著高于无血管病变高血压组 (P <0 0 1)。血浆纤维蛋白原 :伴血管病变高血压组显著高于无血管病变高血压组及对照组 (P <0 0 1) ;无血管病变高血压组与对照组比差异无显著性。结论　伴缺血性心脑血管病变高血压病人的血小板活化程度增高 ,在高血压合并血栓性疾病的检测中 ,血小板活化指标比血浆纤维蛋白原更敏感

The expression of platelet activity in hypertensive patients complicated with ischemic cardiovascular and cerebrovascular disease

Objective To observe the change of platelet activity marker in hypertensive patients complicated with ischemic cardiovascular and cerebrovascular disease ,and assess it s value in the happening of thrombotic disease. Method The platelet activity marker (CD62p,CD63) were measured by flow cytometry in 40 hypertensive patients complicated with ischemic cardiovascular and cerebrovascular disease (group C ),46 hypertensive patients not complicated with ischemic cardiovascular and cerebrovascular disease (group B),and 30 cases of healthy control (group A). Comparison between three groups were made. The serum fibrinogen were measured at the same time. Result serum level of CD62p, and CD63 in group B,C are higher than group A.(P<0 05-0 01).CD62p and CD63 in group C is higher than that in group B.(P<0 01).The serum level of fibrinogen in group C is higher than group A,B(P<0 01). There are not significant difference about serum level of fibrinogen between group A and group B.Conclusion The platelet activity increased in the hypertension patients complicated with cardiovascular and cerebrovascular disease .the platelet activity marker is more sensitive than fibrinogen measurement in detecting hypertensive patients complicated with thrombotic disease.
