For comparison, in the control group, in patients without signs of CVD, without coronary artery atherosclerosis, plasma MMP9 concentration averaged 89 ng/mL (78–95) [69–100] ng/mL, LVEF 64% (59–66) [54–77], LVEDV 138 mL (134–139) [110–146]. This evidence concerns the gene MMP9 and coronary atherosclerosis.
