摘　　要：Abstract Reperfusion rate of infarct related vessels has been significantly increased since the introduction of emergency percutaneous transluminal coronary angioplasty (PTCA) into acute myocardial infarction (AMI) with the major limitation of acute reocclusion. Intracoronary stenting is highly effective in preventing and treating acute reocclusion after PTCA, but it is still disputable whether stent can be applied in AMI due to the presence of intracoronary thrombosis. Objective To evaluate the initial experience of intracoronary stenting in patients with acute myocardial infarction (AMI) in our hospital. Methods Ballon expansion stents were deployed in 18 patients (male: 15, female 3, aged between 38 72 years old) with AMI after emergency PTCA. The major indications for intracoronary stenting in our present study include: 1) acute reocclusion or high risk of reocclusion due to intimal dissection; 2) severe residual stenosis (≥50% diameter stenosis) after repeat balloon dilation; and 3) obvious elastic recoil failed to response to repeat intracoronary nitroglycerin infusion. The dilating pressure for stent implantation was 12 18 atm with a dilating time of 10 30 sec. Patients were heparized during catheter maneuvers and were medicated with Ticlopidine (250 mg, twice daily) for 3 months and aspirin (250 mg, once daily) after stenting. Results 1) Coronary angiography (CAG) showed Department of Cardiology, Zhu Jiang Hospital, The First Military Medical University, Guangzhou 510282, China (Liu YF, Fu XY, Qian XX, Liu Lei, Wu ZJ, Lu DF, Zhao X) that all patients (n=18) had a single vessel total occlusion (left anterior decending 9, right coronary artery 8, and left circuflex 1) before emergency PTCA and was successfully restored to TIMI 3 grade blood flow after intracoronary stenting (13 with Nir stent, 1 with Jonson and Jonson stent, and 4 with Cordis stent). 2) Minor residual intracoronary thrombosis was presented in 5 of 18 patients after PTCA, and it was totally disppeared afAbstract Reperfusion rate of infarct related vessels has been significantly increased since the introduction of emergency percutaneous transluminal coronary angioplasty (PTCA) into acute myocardial infarction (AMI) with the major limitation of acute reocclusion.
