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
Figure 2
Occluded SV graft to the right coronary artery was found in the follow up coronary angiography (Figure 2(a)) that was perfomed in a patients with clinical progression of CAD. Immunohistochemically assessed expression of MMP-2 (Figure 2(b)) was stronger (IRS scale 9) than either TIMP-2 (Figure 2(c)) (IRS scale 1) or TIMP-3 (Figure 2(d)) (IRS scale 1). Abbreviations: AA = ascending aorta, L = lumen of the graft, and SV = saphenous vein.
