急性心肌梗塞患者超氧化物歧化酶与血液流变性、血小板聚集的关系

Relationship between SOD, Hemorheological Property and Platelet Aggregation in Acute Myocardial Infarction Patients

观察２０例急性心肌梗塞患者血液流变性、血小板聚集与超氧化歧化酶（ＳＯＤ）等指标。结果表明急性心肌梗塞时血液流变性异常、血小板聚集增高、ＳＯＤ降低，Ｐ＜０．０１。提示：血液流变性异常和血小板聚集可导致急性、慢性心肌缺血的加重。急性心肌梗塞再灌注产生大量的氧自由基加重缺血心肌超微结构的损害，使心肌梗塞范围扩大，更易发生室速和室颤动。

Twenty patients with acute myocardial infarction disease were observed. Relationship among SOD, hemorheology and platelet aggregation was discussed. Results indicate that the acute myocardial infarction patients' SOD connects with hemorheology and platelet aggregation and that p>0. 01 . It is indicated that the abnormal change connects with acute myocardial infarction . Abnormally of hemorheology and platelet aggregation are able to bring about acute and chronic coronary insufficiency.
