摘要
目的探讨不同负荷剂量替罗非班对急性ST段抬高型心肌梗死患者经皮冠状动脉介入(PCI)术后相关性心肌损伤与动脉血流情况的影响。方法选取2013年3月至2015年3月于湖北省襄阳市中心医院行PCI术的急性ST段抬高型心肌梗死患者180例,根据随机数字表法将患者分为对照组和观察组,各90例。对照组PCI术前给予单倍负荷剂量替罗非班,观察组PCI术前给予双倍负荷剂量替罗非班。比较2组患者术前及术后6、18、24h的肌酸激酶同工酶(CK—MB)和心肌肌钙蛋白I(cTnI)水平,术后心肌梗死溶栓治疗(TIMI)血流分级和心肌灌注分级情况;术后6个月随访2组患者主要心血管不良事件及出血、血小板减少症的发生情况。结果2组患者术后6、18、24h血清CK—MB和cTnI水平均明显高于术前[对照组:(170±23)、(244±121)、(125±47)U/L比(65±62)U/L;(4.13±1.25)、(9.47±2.47)、(3.85±1.36)μg/L比(0.13±0.04)μg/L;观察组:(139±38)、(179±93)、(91±40)U/L比(65±62)U/L;(2.07±0.45)、(4.48±1.43)、(3.18±1.09)μg/L比(0.12±0.04)μg/L],差异均有统计学意义(均P〈0.05)。观察组术后6、18、24h血清CK-MB和cTnI水平明显低于对照组,差异均有统计学意义(均P〈0.05)。观察组术后TIMI血流和心肌灌注3级率均明显高于对照组[91.1%(82/90)比74.4%(67/90),88.9%(80/90)比75.6%(68/90)],差异均有统计学意义(均P〈0.05)。观察组术后6个月内心血管不良事件发生率低于对照组[5.6%(5/90)比15.6%(14/90)],差异有统计学意义(P〈0.05);2组患者出血和血小板减少发生率比较,差异均无统计学意义(均P〉0.05)。结论双倍负荷剂量替罗非班能减轻急性ST段抬高型心肌梗死患者PCI术相关性心肌损伤,改善术后�
Objective To explore the effects of different loading doses of tirofiban on myocardial injury and artery blood flow in patients with acute ST-elevation myocardial infarction(STEMI) after percutaneous coronary intervention(PCI). Methods Totally 180 patients with acute STEMI after PCI from March 2013 to March 2015 in Xiangyang Central Hospital, Hubei Province were enrolled and randomly divided into control group (90 cases) and observation group(90 cases). The control group had single loading dose of tirofban and the observation group had double loading doses of tirofiban before PCI. Creatine kinase isoenzyme-MB (CK-MB) and cardiac troponin I (cTnI) were tested before and 6, 18, 24 h after PCI. Thrombolysis in myocardial infarction(TIMI) flow classifi- cation and myocardial perfusion classifcation were measured after PCI. Major adverse cardiovascular events (MACE), hemorrhage and thrombocytopenia were recorded. Results Levels of CK-MB and cTnI 6, 18, 24 h after PCI were significantly higher than those before PCI in both groups[ control group:( 170± 23 ) , (244 ± 121 ) , ( 125 ±47)U/L vs (65 ±62)U/L; (4.13 ± 1.25), (9.47 ± 2.47), (3.85 ± 1.36) μg/L vs (0.13 ±0.04) μg/L; observation group : ( 139 ± 38 ), ( 179 ± 93 ), (91 ± 40) U/L vs ( 65 ± 62 ) U/L; ( 2.07 ± 0.45 ), (4.48 ± 1.43 ), (3.18 ± 1.09) μg/L vs (0.12 ±0.04) μg/L] (P 〈0.05). Levels of CK-MB and eTnI in observation group were significantly lower than those in control group 6, 18, 24 h after PCI(P 〈0.05). Grade 3 rates of TIMI flow andmyocardial perfusion in observation group were significantly higher than those in control group [ 91.1% (82/90) vs 74.4% (67/90) ; 88.9% (80/90) vs 75.6% (68/90)]( P 〈 0.05 ). Incidence of MACE in observation group was significantly lower than that in control group [ 5. 6% ( 5/90 ) vs 15.6% ( 14/90 ) ] ( P 〈 0. 05 ) ; incidences of hemorrage and thrombocytopenia sh
