Demographic characteristics and laboratory data at baselines among CAD patients stratified by medians of matrix metalloproteinase-2, -3 and -9 levels, respectively.

Medians of baseline plasma MMP-2, MMP-3, and MMP-9 levels were 861 ng/mL, 227 ng/mL, and 49 ng/mL, respectively.Comparison between two groups of patients with different MMP-2, -3, and -9 levels by the student’s t test, Pearson x2 test, or the Mann-Whitney U test, as appropriate.aPbPACEI, angiotensin-converting enzyme inhibitors; ARB, angiotensin II receptor blockers; CAD, coronary artery disease; CRP, C-reactive protein; DHP, dihydropyridine; eGFR, estimated glomerular filtration rate; HDL, high density lipoprotein; LDL, low density lipoprotein; MMP, matrix metalloproteinase.
