The short-term outcome of primary percutaneous coronary intervention for patients with acute myocardial infarction / 介入放射学杂志

ABSTRACT

Objective To evaluate the efficacy of primary percutaneous coronary intervention (PCI) for acute myocardial infarction. Methods 63 patients with acute myocardial infarction were treated by primary PCI within 12 hour from onset and were followed up for one to fourteen months. Results Procedure was successed in 61 patients (96.8%). Three patients received only primary angioplasty and 58 patients received stent implantation. All of them gained TIMI Ⅲ grade perfusion flow. Non-perfusion flow occurred in five patients but their flows were improved by intracoronary urokinase infusion. Ventricular tachycardia and fibrillation happened in five patients, and were converted to sinus rhythm by defibrillation in four and one died. Two of the five patients complicated with cardiogenic shock, with one died on 1st day and the other on 4th day after successful PCI, respectively. Main cardiac events occurred in five patients (17%) during follow-up with two sudden death , one reinfarction and repeated PCI, one received selective CABG and one PCI due to intrastent restenosis. Conclusions Primary PCI could provide higher successful rate of reperfusion with low hospital mortality and good short-term prognosis.
