Objective To further improvethe rate of reperfusion of infarction related artery in AMI, remove the stricture, rescue ischemic myocardium, protect cardiac function and ameliorate the long -term prognosis. Method Among 73 patients with A-MI, 50 underwent direct PICA, 15 immediate PICA, 8 rescue PTCA and 20 braces were implanted. Result The proportion of recanalization is 94. 5% (69/73) . The grade of blood flow (TIMI) improved to grade 3 in 20 patients with brace implantation, while 44 to grade 3 and 5 to grade 2 among 49 patients with simple PTCA. Residualstenosis in vessel was 1.8±5.9 ( -10-10)% in patients with brace implantation versus 15. 4±11. (0-30)% with simple PTCA. The incidence of reperfusive cardiac arrythmia was 18. 1% (10/62). There was mainly frequent ventricular premature beat and short paroxysmal ventricular tachycardia, if left anterior decending branch was reopened, while bradycardia and atrial ventricular block usually occurred after right coronary reperfused. Conclusion Emergency PTCA and brace implantation can apparently improve the proportion of reperfusioa of IRA in AMI. It is necessary to popularize and apply these treatment in medical units with available conditions.
