Variation in serum visfatin levels 24 hours after coronary stent implantation / 中国组织工程研究

ABSTRACT

BACKGROUND:Coronary stent implantation can cause blood vessel damage and wal reconstruction, leading to vascular stent restenosis. Studies have found that visfatin is associated with inflammatory reaction, and exhibits an increased expression at the site of plaque rupture in acute myocardial infarction. OBJECTIVE:To investigate the influence of percutaneous coronary intervention on the levels of visfatin in patients with coronary heart disease. METHODS:Thirty patients with acute myocardial infarction within 12 hours after the onset of the chest pain, 30 patients with unstable pectoris and 30 patients with stable angina pectoris were included. Al patients were successfuly treated by percutaneous coronary intervention. Meanwhile, 30 patients only undergoing coronary angiography but not stenting treatment were selected, and another 30 patients without any treatment served as normal control group. RESULTS AND CONCLUSION:According to enzyme-linked immunosorbent method, the visfatin levels of acute myocardial infarction, unstable angina, stable angina and coronary angiography groups continue to rise at pre-operation, 30 minutes, 6 hours, 12 hours, 24 hours after operation, al of which were higher than that in the normal control group (P < 0.05). The results confirmed that within 24 hours after coronary stent implantation the visfatin levels continue to rise.
