Unadjusted rates of percutaneous coronary intervention (PCI) for occlusions identified after myocardial infarction (MI) over time. The unadjusted rate of PCI for persistent total coronary artery occlusions after acute MI over the study period is shown, along with 95% confidence intervals, for the overall study population (A), for patients presenting with an ST elevation MI (B), and only those patients treated in hospitals in the highest quartile for reporting of diagnostic catheterizations (C). CI indicates confidence interval; OAT, the Occluded Artery Trial.
