Intracoronary stents were implanted in 15 patients after unsuccessful PTCA in the setting of acute myocardial infarction (AMI). The stented vessel was the left anterior descending (LAD) in 11 patients, the right coronary artery (RCA) in 3 patients, and a venous bypass graft to the LAD in a single patient. A total of 16 stents were implanted (15 Palmaz Schatz, Johnson and Johnson; and 1 Wiktor, Medtronic).
FOLLOW-UP: 1 patient died 10 days after stent implantation as a result of renal failure and cardiogenic shock. Subacute thrombosis occurred in 2 patients, 5 and 15 days after stent implantation; both underwent successful emergency coronary artery bypass grafting (CABG). The remaining 12 patients were free from major ischemic events (death, AMI, and further revascularization) after a mean follow-up of 18.7 +/- 4.1 months. We conclude that the long-term results of intracoronary stenting in AMI after failed PTCA are favourable.
15例急性心肌梗死（AMI）患者在经皮冠状动脉腔内血管成形术（PTCA）失败后植入了冠状动脉内支架。11例患者植入支架的血管为左前降支（LAD），3例为右冠状动脉（RCA），1例为LAD的静脉搭桥血管。共植入16枚支架（15枚Palmaz Schatz，强生公司；1枚Wiktor，美敦力公司）。
1例患者在支架植入10天后因肾衰竭和心源性休克死亡。2例患者在支架植入后5天和15天发生亚急性血栓形成；二者均成功接受了急诊冠状动脉搭桥术（CABG）。其余12例患者在平均随访18.7±4.1个月后未发生重大缺血事件（死亡、AMI和进一步血运重建）。我们得出结论，PTCA失败后AMI患者冠状动脉内支架置入的长期结果良好。
