摘要
目的:探讨替罗非班对直接经皮冠状动脉介入治疗(PCI)的急性心肌梗死(AMI)患者心肌灌注及临床预后的影响.方法:将AMI住院患者60例随机分为替罗非班治疗组(A组,予直接PCI+替罗非班,n=30)和对照组(B组,仅予直接PCI,n=30).比较两组间的基础临床状况、造影情况、介入治疗结果、心功能和心脏不良事件(MACE,包括死亡、再梗死、再次靶血管重建)发生率.结果:两组基础临床情况、介入治疗结果差异均无统计学意义.与B组相比,A组术后即刻心肌梗死溶栓试验(TIMI)3级复流血流差异无统计学意义(93% vs 86%,P>0.05).即刻心肌Blush分级3级(77.0%vs 33.0%,P<0.05)显著高于B组,而校正TIMI帧数[(23.5± 7.6)帧和(32.1±4.2)帧,P<0.05]显著低于B组.A组术后ST段抬高总和回落[(69.8±14.2)%和(38.6±11.7)%,P<0.05]显著高于B组,而肌酸激酶(CK)峰值[(28.4±5.0)和(37.7±8.7)μkat/L,P<0.05]显著低于对照组.住院期间,A,B两组左室射血分数(LVEF)[(45.8 ± 2.7)%和(44.7±3.8)%]、左室舒张期末直径(LVEDD)[(4.95±0.31)cm和(4.99 ± 0.27)cm]差异均无统计学意义.随访期间,A,B两组LVEF[(58.1 ± 3.6)%和(51.1±2.4)%]、LVEDD[(5.2±0.2)cm和(5.5±0.2)cm]差异均有统计学意义(P<0.05).两组住院期间和随访期间各项心脏事件发生率差异有统计学意义(P<0.05).A组术后出血并发症发生率高于B组(23.3% vs 7.0%),但差异无统计学意义(P > 0.05).结论:替罗非班可改善PCI的AMI患者心肌灌注及临床预后,且临床应用安全.
Abstract
AIM: To investigate the effect of glycoprotein IIb/IIIa receptor blockade with tirofiban on the clinical outcomes and myocardial blush perfusion recovery in acute myocardial infarction (AMI) patients treated by primary percutaneous coronary intervention (PCI). METHODS: Sixty AMI patients were randomized to receive either tirofiban plus primary PCI (group A, n = 30) or primary PCI alone (group B, n = 30). Baseline characteristics, results of primary PCI, cardiac function and the incidence of cardiac events were compared between the 2 groups. RESULTS: No significant difference was observed between the 2 groups in basic clinical or angiographic characteristics before PCI and in the percentage of TIMI 3 flow achieved in infarction related arteries (IRAs) after PCI (P ＞ 0.05, respectively). Fewer TIMI frames [(23.5 ± 7.6) frames us (32.1 ± 4.2) frames, P ＜ 0.05] and higher percentage of blush grade 3 of IRAs (77.0% vs 33.0%, P ＜ 0.01) were observed in tirofiban group. Follow-up data before hospital discharge showed lower peak serum CK levels [(28.4 ± 5.0)μkat/L,(37.7 ± 8.7) μkat/L, P ＜ 0.05] and faster ST segment resolution in the tirofiban group after PCI [(69.8 ± 14.2)% vs (38.6 ± 11.7)%, P ＜ 0.05]. During hospital stay, no significant difference in LVEF and LVEDD was observed between the two groups (both, P ＞ 0.05) but significant difference was found during follow-up period (both, P ＜ 0.05). No significant difference in postoperative bleeding-related complications was found between the 2 groups (P ＞ 0.05), but the main adverse cardiac events (MACE) between the 2 groups were significantly different (P ＜ 0.05). CONCLUSION: Adjutant therapy with tirofiban is safe and effective for patients with acute myocardial infarction who undergo primary PCI. Tirofiban improves the clinical outcomes and myocardial blush perfusion after PCI.
