Abstract:
Objective The purpose of the present study was to identify the relationship between the plasma level of adiponectin and in-stent restenosis of patients with coronary heart disease after coronary stenting. Method The study population comprised 119 individuals (92 men ) who underwent stent implantation, including 65 subjects without in-stent restenosis (group A ) and 54 patients with in-stent restenosis (group B). The level of plasma adiponectin was measured using ELISA. Coronary angiography was performed immediately before and after implanting stent and 9-12 months later. Results Baseline characteristics including drug use after PCI were similar between the groups. The rate of implanting bare metal stent is 8(12. 31% ) and 6(11.11% ), TAXUS drug-eluting stent is 11 (16. 92% ) and 10(18.52%) and CYPHER drug-eluting stent is 46 ( 70. 77% ) and 38 ( 70. 37% ) respectively ( all P > 0. 05 ). Plasma level of adiponectin in patient of group A was significantly higher than that in group B [ ( 15. 16±5.02 )mg/L vs. ( 10. 01±4. 93 ) mg/L, P < 0. 05 ]. The quantitative coronary angiography ( QCA ) showed that lesion length was similar between groups [ ( 15.82±: 6. 67 ) mm vs. ( 13.40±4. 20 )mm, P > 0. 05 ], minimum lumen diameter(MLD) and stenosis rate were also similar before and after implanting stent ( P > 0. 05 ) and acute gain was ( 1.48±0. 65 ) mm vs. ( 1.19±0. 37 ) mm ( P > 0. 05 ). MLD was higher in group A than that in group B [(2.55±0.53)mm vs. (0.57±0.60)mm, P<0.01] at 9-12 months follow up. Restenosis rate [(24.2±11.2)% vs. (81.0±19.1)%,P<0.01] and late lumen loss [(0.50±0.34)mm vs.( 1.60± 0. 54)mm, P < 0. 01 ] were lower in group A than in group B. Conclusions The lower plasma adiponectin level might be associated with in-stent restenosis after coronary stenting.
