Predictors of outcome and the lack of effect of percutaneous coronary intervention across the risk strata in patients with persistent total occlusion after myocardial infarction: Results from the OAT (Occluded Artery Trial) study.

ABSTRACT:

Objectives

This study sought to determine predictors of outcome and examine the influence of baseline risk on therapeutic impact of late mechanical opening of a persistently occluded infarct related artery after myocardial infarction in stable patients.

Background

Previous studies in patients with acute coronary syndromes suggest that the impact of infarct-related artery recanalization on clinical outcome is greatest in patients at highest risk.

Methods

Of 2,201 patients (age 58.6 +/- 11.0 years) with infarct-related artery occlusion on days 3 to 28 after myocardial infarction in the OAT (Occluded Artery Trial) study, 1,101 were assigned to percutaneous coronary intervention (PCI) and 1,100 to medical therapy alone and followed for a mean of 3.2 years. The primary end
