【摘要】 本研究见察了５０例急性心肌梗塞（ＡＭ１）患者、４６例不稳定型心绞痛（ＵＡ Ｐ）患者、５０例正常对照者（ＮＣ）血小板四项参数及血液流变学变化．结果表明：ＡＭＩ及ＵＡＰ与ＮＣ组比较血小板数目减少（Ｐ＜０．０５或 Ｐ＜０．０１），以ＡＭＩ组减少更为明显．血小板压积．平均血小板体积和血小板分布宽度均有不同程度增高（Ｐ＜０．０５式Ｐ＜０．０１），以ＡＭＩ组增高更为明显．ＡＭＩ及ＵＡＰ与ＮＣ组相比较血液流变学各项指标均有不同程度增高（Ｐ＜０．０５或Ｐ＜０．０１），以ＡＭＩ组增高更为明显．结果提示：血小板功能亢进及血液高粘滞状态在冠心病的发生发展中起很重要作用，血液粘度可能与冠状动脉病变的严重程度有关．更多还原

【Abstract】 Obiectiue: To study the changes of four factors in platelet and hemorrhedogy in patients with coronary heart disease. Methods: Observed the changes of four factors in platelet and the changes of hemorrheology in 50 patients with acute myocardial infarction (AMI)、46 patienst with unstable angina pectoris(UAP)、50 normal control(NC). Results :The platelet number in AMI and UAP was lower than in NC. PCT、MPU、DDU in AMI and UAP was higher than in NC. The indexes about hemorheolgical changes in AMI and UAP was higher than in NC. Conclusions: platelets activity and hemorheological disorder are likely] associated with the cause of coronary heart disease.更多还原
