[Effect of myocardial revascularization on dynamics of factors of angiogenesis in patients with ischemic heart disease].
Aim of the study was to assess effect of myocardial revascularization on levels of factors of angiogenesis in early and remote period after intervention. Main group comprised 228 patients with ischemic heart disease (n=228, 194 men, 34 women, mean age 57+/-8.7 years). Coronary bypass surgery was carried out in 29 patients while other 199 were subjected to percutaneous coronary intervention (PCI). Analysis of data was performed in the group as a whole and in 2 subgroups distinguished in dependence on type of invasive treatment. Levels of factors of angiogenesis - vascular endothelial growth factor (VEGF), transforming growth factor beta (TGFbeta), and endostatin - were measured before, in 6 days, and 6 months after invasive treatment. Compared with healthy persons patients with IHD had significantly higher level of VEGF and significantly lower levels of TGFbeta and endostatin. On day 6 after revascularization in the group as a whole level of VEGF insignificantly rose while level of TGFbeta insignificantly decreased. In 6 months after invasive treatment significant lowering of VEGF level and significant increase of TGFbeta was noted. Endostatin level was measured at baseline and in 6 months after invasive treatment. Significant elevation of endostatin level took place after 6 months. Thus PCI and coronary bypass surgery lead to lowering of VEGF level and elevation of levels of TGFbeta in 6 days after intervention. In remote period reverse dynamics was observed: of VEGF level rose and those of TGFbeta and endostatin increased.
