校正TIMI计帧法对ST段抬高型心肌梗死患者预后的预测作用分析

Analysis on the Predictive Effect of Calibrated TIMI Frame Count on the Prognosis of Patients with ST-Segment ElevationMyocardial Infarction

目的探讨校正TIMI计帧法对ST段抬高型心肌梗死(STEMI)患者预后的预测作用。方法 50例STEMI患者根据校正TIMI帧数(CTFC)分为观察组(14≤CTFC<23)和对照组(23≤CTFC<40),每组各25例。比较两组的CTFC、 LS、RS、 LVEF,分析两组CTFC与LS及RS的相关性。结果观察组的CTFC低于对照组,LS、 RS、 LVEF高于对照组(P <0.05)。两组的CTFC与LS及RS之间均具有负相关关系(P <0.05)。观察组的不良事件发生率低于对照组(P <0.05)。结论 CTFC可以较好地评价STEMI患者的心肌功能状态,反映患者的心肌微循环灌注,有效预测预后。

Objective To explore the predictive effect of calibrated TIMI frame count on the prognosis of patients with ST-segment elevation myocardial infarction(STEMI).Methods 50 STEMI patients were divided into observation group(14≤CTFC<23)and control group(23≤CTFC<40)according to the calibrated TIMI frame count(CTFC),with 25 cases in each group.CTFC,LS,RS and LVEF were compared between two groups,and the correlations of CTFC with LS and RS in the two groups were analyzed.Results The CTFC of observation group was lower than that of control group,while the LS,RS and LVEF were higher than those of control group(P<0.05).CTFC was negatively correlated with LS and RS in both groups(P<0.05).The incidence of adverse events of observation group was lower than that of control group(P<0.05).Conclusions CTFC can better evaluate the myocardial function status of STEMI patients,reflect the myocardial microcirculation perfusion,and effectively predict the prognosis of patients.
