PG - 802-6 AB - BACKGROUND: Post myocardial infarction (post-MI) patients with low left ventricular ejection fraction (LVEF) have been candidates for an implantable cardioverter-defibrillator (ICD) since the Multicenter Automatic Defibrillator Implantation Trail II (MADIT II). However, due to the high costs of ICDs, widespread usage has not been accepted. Therefore, further risk stratification for post-MI patients with low LVEF may aid in the selection of patients that will benefit most from ICD treatment. METHODS: Four hundred and seventeen post-MI patients with low LVEF (< or = 35%) were enrolled in the study. All the patients received standard examination and proper treatment and were followed up to observe the all-cause death rate and sudden cardiac death (SCD) rate. Then COX proportional-hazards regression model was used to investigate the clinical factors which affect the all-cause death rate and SCD rate. RESULTS: Of 55 patients who died during (32 +/- 24) months of follow-up, 37 (67%) died suddenly. After adjusting for baseline clinical characteristics, multivariate COX proportional-hazards regression model identified the following variables associated with death from all causes: New York Heart Association (NYHA) heart failure class > or = III (Hazard ratio: 2.361), LVEF < or = 20% (Hazard ratio: 2.514), sustained ventricular tachycardia (Hazard ratio: 6.453), and age > or = 70 years (Hazard ratio: 3.116). The presence of sustained ventricular tachycardia (Hazard ratio: 6.491) and age > or = 70 years (Hazard ratio: 2.694) were specifically associated with SCD. CONCLUSIONS: In the post-MI patients with low LVEF, factors as LVEF < or = 20%, age > or = 70 years, presence of ventricular tachycardia, and NYHA heart failure class > or = III predict an adverse outcome. The presence of sustained ventricular tachycardia and age > or = 70 years was associated with occurrence of SCD in these patients.
