AS-135 Incidence of Tachyarrhythmia and its Impact on Two-Year Clinical Outcomes in Patients with ST Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention with Drug-Eluting Stents

Results: The STEMI group showed higher incidence of sustained ventricular tachycardia (VT), non-sustained VT, ventricular fibrillation (VF) and atrial fibrillation (AF) compared with those of other two groups. The baseline clinical and procedural characteristics were similar between pts with tachyarrhythmia and those of control group. Six-month angiographic and cumulative clinical outcomes up to 2 years were similar between the two groups except pts with tachyarrhythmia showed higher incidence of cardiac death within 1 month compared with control group but not at 6 to 24 months (Table 1). Tachyarrhythmia itself was not an independent predictor of cardiac death (Adjusted OR: 1.711, 95% CI: 0.443-6.616, p-value=0.436) within 1 month.
