Abstract

Left ventricular (LV) remodeling after myocardial infarction (MI) is a strong predictor of heart failure and mortality. The predictors of long-term remodeling after MI have been incompletely studied. We therefore examined the correlates of LV remodeling in patients with large ST-segment elevation myocardial infarction and a patent infarct artery after percutaneous 2coronary intervention (PCI) from the randomized Post-Myocardial Infarction Remodeling Prevention Therapy trial. Peri-infarct pacing had a neutral effect on long-term remodeling in patients with large first MI. The present analysis includes 109 patients in whom an open artery was restored after PCI, and in whom LV end-diastolic volume (LVEDV) at baseline and 18 months was assessed by transthoracic echocardiography. Multivariable models were fit to identify the independent predictors of LVEDV at baseline and 18 months. By multivariable analysis, male sex (p = 0.004) and anterior MI location (p = 0.03) were independently associated with baseline LVEDV. The following variables were independent predictors of increased LVEDV at 18 months: younger age (p = 0.01), male sex (p = 0.03), peak creatine phosphokinase (p = 0.03), shorter time from MI to baseline transthoracic echocardiography (p = 0.04), baseline LVEDV (p < 0.0001), and lack of statin use (p = 0.03). In conclusion, patients with large MI and an open infarct artery after PCI, anterior MI location, and male sex were associated with greater baseline LVEDV, but MI location was not associated with 18-month LVEDV. In contrast, younger age, peak creatine phosphokinase, male sex, baseline LVEDV, and lack of statin use were associated with long-term LV remodeling.
