Comparing changes in metalloproteinases-2, 3, and 9 between acute and quiescent time-points, a–c Primary analysis—acute myocardial infarction versus stable coronary artery disease; d–f Sub-Group analysis—atherothrombotic versus non-atherothrombotic myocardial infarction. CAD Coronary artery disease, CI confidence interval, MI myocardial infarction, SD standard deviation, T0 at time of cardiac catheterization, T6 6 hours post T0, Quiescent Phase (TF/U) ~ 3 month follow-up during a healthy state (without any illness). *P values calculated via repeated measures ANOVA
