目的 :观察和分析急性心肌梗塞 ( AMI)时血小板计数 ( BPC)及平均血小板体积 ( MPV)的变化。方法 :用 MICRO- OT- 1 8型全自动血细胞分析仪对 52例 AMI患者的 BPC和 MPV进行测定 ,并与 50例健康查体者的检测值做对照。结果 :发现 AMI患者的 BPC比对照组显著减少 ( P<0 .0 1 ) ,MPV比对照组显著增大 ( P<0 .0 5)。结论 :AMI患者冠状动脉血栓的形成可能与 MPV增大有一定关系 ,而与血小板的数量关系不大。
Objective: To observe and analyze the changes of platelet count (BPC) and mean platelet volume (MPV) in patients with acute myocardial infarction (AMI). Methods: The BPC and MPV of 52 patients with AMI were measured by MICRO-OT-18 automatic hematology analyzer and compared with the results of 50 healthy people. Results: The BPC of patients with AMI was significantly lower than that of the control group (P <0.01), and the MPV of patients with AMI was significantly higher than that of the control group (P <0.05). Conclusion: The formation of coronary thrombosis in patients with AMI may have a certain relationship with the increase of MPV, but not with the number of platelets.
