摘要
目的探讨老年急性心肌梗死（AMI）患者血小板参数的临床意义。方法 对2007年3月—2010年11月收治的老年AMI患者84例（AMI组）与同期健康查体者90例（健康对照组）应用血细胞分析仪测定血小板（PLT）计数、血小板平均体积（MPV）和血小板分布宽度（PDW）值,并进行比较。结果 AMI组PLT低于健康对照组[（221±62）×10~9/L vs（280±32）×10~9/L],MPV和PDW高于健康对照组[分别为（10.30±1.08）fl vs（9.80±0.50）fl和（13.01±2.07）%vs（11.48±0.40）%],差异均有统计学意义（P〈0.05）;并且AMI组PLT与MPV、PDW呈负相关（r=-0.34l,r=-0.462,P均〈0.05）。结论急性心肌梗死患者PLT计数下降,MPV、PDW升高,血小板活化是AMI的独立危险因素。
Objective To investigate the clinical significance of platelet parameters in elderly acute myocardial infarction （AMI） patients.Methods Apply US Kurt company TT-R1 type blood cells analyzer to determine PLT,MPV and PDW value in 84 elderly patients with AMI（AMI group） and 90 people at the same period（healthy control group） from March 2007 to November 2010,recorded and analyzed these data.Results PLT of AMI group was lower than those of the healthy control groupt（221±62）×10~9/L vs（280±32）×10~9/L],MPV and PDW are higher than those in the healthy control group [（10.30±1.08）fl vs（9.80±0.50）fl and（13.01±2.07）%vs（11.48±0.40）%],the differences have statistical significant （P 0.05 ）;PLT were negatively correlated with MPV,PDW of AMI group（r = - 0.341,r = - 0.462,P 0.05 ）. Conclusion PLT decreased,MPV and PDW were increased,during onset of acute myocardial infarction,activation of platelet is an independent risk factor of AMI.
