Abstract

AIMS:

Left ventricular systolic function and presence of heart failure (HF) are important prognostic factors and dictate future therapeutic strategies after myocardial infarction (MI). We evaluated persistence of the prognostic importance of left ventricular dysfunction and HF in consecutive MI patients screened for entry in the Trandolopril Cardiac Evaluation Registry (TRACE) study.

METHODS AND RESULTS:

The study population comprised 6676 MI patients screened for entry into the TRACE study, a double-blind, randomized, parallel group, placebo-controlled study of trandolapril vs. placebo in patients with left ventricular dysfunction after MI. In unadjusted analysis, patients with reduced left ventricular function and HF continued to show increased mortality. Landmark analysis and Cox proportional-hazards models showed that wall motion index (WMI) was a significant prognostic factor until 10 years of follow-up with hazard ratios ranging between 0.74 [confidence interval (CI) 0.71-0.78] and 0.90 (CI 0.82-0.98) associated with a 12% improvement in left ventricular ejection fraction (0.4 WMI units). The prognostic significance of HF persisted for 8 years with hazard ratios between 1.47 (CI 1.21-1.78) and 2.62 (95% CI 2.30-2.98) for the first 8 years.

CONCLUSION:

When assessed during the index MI, WMI and HF carry prognostic information for up to 10 years.
