血小板分布宽度与老年急性非ST段抬高型心肌梗死病人Killip分级的相关性分析

Correlation analysis of the platelet distribution width and Killip grading in elderly patients with acute non-ST-segment elevation myocardial infarction

摘要

摘要:
目的探讨血小板分布宽度（PDW）与老年急性非ST段抬高型心肌梗死（NSTEMI）病人Killip分级的相关性。
方法选取158例老年急性NSTEM病人，根据心功能Killip分级Ⅰ、Ⅱ、Ⅲ、Ⅳ级分为4组，记录所有病人临床资料，测定各组PDW；采用Spearman等级相关分析PDW与老年急性NSTEM病人Killip分级的相关性。
结果随着Killip分级Ⅰ、Ⅱ、Ⅲ、Ⅳ级升高，PDW逐渐升高（P < 0.01）。经Spearman等级相关分析显示，PDW与心功能Killip分级呈正相关（r_s=0.792，P < 0.01）。
结论PDW与老年急性NSTEM病人Killip分级呈正相关，可能作为评估病人心功能预后指标之一。

Abstract:
ObjectiveTo study the correlation between the platelet distribution width(PDW) and Killip gerading in the elderly patients with acute non-ST-segment elevation myocardial infarction(NSTEMI).
MethodsOne hundred and fifty-eight elderly patients with acute NSTEMI were divided into 4 groups according to the Killip grading Ⅰ, Ⅱ, Ⅲ and Ⅳ of cardiac function.The clinical data of all patients were recorded, and the PDW in four groups were measured.The Spearman rank correlation was used to analyze the correlation between PDW and Killip grading in elderly patients with acute NSTEMI.
ResultsThe PDW increased gradually with the increasing of Killip grading Ⅰ, Ⅱ, Ⅲ and Ⅳ(P < 0.01).The results of Spearman rank correlation analysis showed that the PDW was positively correlated with cardiac function Killip grading(r_s=0.792, P < 0.01).
ConclusionsThe PDW is positively correlated with Killip grading in elderly patients with acute NSTEMI, which may be one of the prognostic indexes for evaluating cardiac function.
