【摘要】：目的探討行急診經皮冠脈介入(PCI)術的急性ST段抬高性心肌梗死(STEMI)患者口服替格瑞洛對血小板聚集率及體表心電圖QT離散度(QTd)的影響及臨床意義。方法明確診斷為STEMI的患者68例隨機分為替格瑞洛組與氯吡格雷組。觀察兩組在急診PCI治療前及治療后血小板聚集率和QTd的變化。結果急診PCI治療前有22例出現室性心律失常,急診PCI后,無室性心律失常出現,QTd在室性心律失常組較非室性心律失常組明顯延長(P0.05);氯吡格雷組術后2、24 h血小板聚集率較術前均明顯下降(P0.05);替格瑞洛組術后2、24 h血小板聚集率較術前均明顯下降(P0.01);與氯吡格雷組比較,替格瑞洛組術后2、24 h血小板聚集率下降更明顯(P0.05);氯吡格雷組QTd術后較術前明顯降低(P0.05),替格瑞洛組QTd術后較術前明顯降低(P0.01),與氯吡格雷組比較,替格瑞洛組下降更明顯(P0.05);住院期間替格瑞洛組與氯吡格雷組出血事件發(fā)生率無明顯差異(P0.05)。結論 STEMI患者行急診PCI術前及術后應用替格瑞洛抗血小板治療,可更快、更強地抑制血小板聚集,顯著縮短QTd,減少惡性心律失常的發(fā)生率。
[Abstract]:Objective to investigate the effect of tigrilol on platelet aggregation rate and QT dispersion of surface electrocardiogram (ECG) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary intervention (PCI). Methods Sixty-eight patients with STEMI were randomly divided into two groups: tigril group and clopidogrel group. The platelet aggregation rate and QTd were observed before and after emergency PCI treatment. Results there were 22 cases of ventricular arrhythmia before emergency PCI treatment. After emergency PCI, no ventricular arrhythmia appeared QTD in the ventricular arrhythmia group than in the non-ventricular arrhythmia group significantly longer than the non-ventricular arrhythmia group. In clopidogrel group, the platelet aggregation rate at 24 h after operation was significantly lower than that before operation (P 0.05). The platelet aggregation rate at 24 h after operation in tigrilol group was significantly lower than that before operation (P 0.01). Compared with clopidogrel group, the platelet aggregation rate of tigrilol group decreased more significantly than that of clopidogrel group at 24 h after operation (P 0.05). Compared with clopidogrel group, clopidogrel group was significantly lower than that of preoperation in QTd group (P 0.05) and tigrilol group (P 0.01) after QTd operation, which was significantly lower than that in clopidogrel group. In tigrilol group, the decrease was more obvious than that in the control group (P 0.05). There was no significant difference in the incidence of bleeding events between the tigrilol group and clopidogrel group during hospitalization P0.05Conclusion the patients with STEMI were treated with tigrello antiplatelet therapy before and after emergency PCI. It can inhibit platelet aggregation more quickly, shorten QTD significantly, and reduce the incidence of malignant arrhythmia.
