Preexisting High Expression of Matrix Metalloproteinase-2 in Tunica Media of Saphenous Vein Conduits Is Associated with Unfavorable Long-Term Outcomes after Coronary Artery Bypass Grafting
Table 3
Mean tissue expressions of MMP-2, TIMP-2, and TIMP-3 in the SV segments obtained from patients who developed the SV graft disease (SVGD (+)) versus individuals without SV graft failure during the follow-up period (SVGD (−)).
