摘　　要：目的:评价超选择性冠状动脉内注射硝普钠对急性心肌梗死(AMI)患者急诊经皮冠状动脉介入(PCI)治疗中梗死相关动脉(IRA)无复流现象的作用。方法:选择AMI急诊PCI后再通的IRA存在无复流现象者43例。21例患者经血栓抽吸导管超选择性梗死相关冠状动脉内注射法,22例患者采用常规指引导管内注射方法。药物均采用硝普钠100μg,2 s内"弹丸式"快速注射完毕。10 min后复查冠状动脉造影,评定冠状动脉血流TIMI分级及校正TIMI帧数(cTFC)。结果:两组均可明显改善急诊PCI后的无再流现象,超选择组所有患者梗死相关血管IRA血流恢复TIMIⅢ级,cTFC帧数由用药前的(84±7)帧降至(26±6)帧,与常规组相比较差异有统计学意义(P<0.01)。结论:超选择性IRA内快速注射硝普钠100μg能更有效地改善AMI急诊PCI中无再流现象。AIM： To evaluate the effect of super-selective intracoronary injection of nitroprusside on no-reflow phenomenon of primary percutaneous coronary intervention （PCI）. METHODS： Forty-three acute myocardial infarction （AMI） patients with no-reflow phenomenon after primary PCI were included in the study. Super-selective intracoronary infarction related artery （IRA） injection from ZEEK thrombus aspiration catheters was used in 21 cases, and routine injection from guiding catheter was used in the other 22 cases. Nitroprusside was injected （100 μg） by 2-sec bolus in both groups. Coronary arteriography （CAG） was rechecked 10 min after injection, and TIMI as well as CTFC of IRA blood flow were evaluated. RESULTS： No-reflow phenomenon was markedly relieved in both groups. All cases in the super-selective group restored TIMI III blood flow and CTFCs of IRA decreased from 83.7±7.02 to 26.5±5.81 （P〈0.001） after super-selective intracoronary injection of nitroprusside, whereas those in the routine group decreased from 84.5±6.45 to 33.8±11.9, with significant difference in IRA TIMI and CTFC between groups （P〈0.01）. CONCLUSION： Super-selective injection of 100 μg nitroprusside in IRA effectively improved no-reflow phenomenon in primary PCI of AMI.
