목적 : 관상동맥질 환자에서 항산화 비타민 C와 E, 항산화제 probucol 병합요법이 스텐트 시술 후 혈중 P-selectin, chemokine, 사이토카인의 농도변화와 스텐트 재협착에 미치는 영향을 연구하였다.방법 : 관상동맥 질환으로 일반 스텐트 시술을 시행한 총 90명의 환자를 항산화제를 복용하지 않은 대조군과 비타민 C와 E, Probucol을 병합 투여한 군으로 나누었으며 이 중 6개월 후 추적관상동맥 조영술을 시행한 환자 71명을 대상으로 비교하였다. 항산화제 치료 전과 6개월 후 혈장내 전체 항산화지수, P-selectin, MCP-1, IL-6과 IL-10을 측정 비교하였고, 6개월 후 관상동맥 조영술을 시행하여 재협착 유무를 조사하였다.결과 : 스텐트 시술 전 임상적 소견, 위험인자, 생화학지표 등은 양 군 간에 유의한 차이가 없었으며 전체 항산화지수, P-selectin, MCP-I, IL-6, IL-10도 양 군 간 유의한 차이가 없었다. 6개월 후 추적검사에서 전체 항산화 지수 P-selectin, MCP-I, IL-6 및 IL-10 역시 양 군 간 유의한 차이가 없었고, 재협착 발생률도 양 군 간 유의한 차이가 없었다.
Background : Oxidative stress might be a role in atherosclerosis and increased intake of antioxidant appear to be protective and modify neointimal formation. An antioxidant and probucol prevents endothelial dysfunction and low density lipoprotein oxidation and also inhibits the secretion of cytokine by macrophages. We aimed 1) to study the effects of antioxidant (Vitamin C, E and probucol) supplementation on serum level of antioxidant status (TAS), P-selectin, MCP-1, IL-6 and IL-10 and 2) to investigate the effects of antioxidant intake on in-stent restenosis. Methods : Total 90 patients were assigned to control or antioxidant group (probucol; 500 mg, vitamin C; 1,000 mg, vitamin E; 400 mg). We performed follow up coronary angiography in 35 patients of antioxidant group and 36 patients of control group after 6 months of coronary bare metal stent implantation. We counted the stenotic lesions more than 50% of implanted stent lumen as a restenosis by quantitative coronary angiography. The serum levels of total antioxidant status, P-selectin, MCP-1, IL-6 and IL-10 were measured. Results : The serum levels of total antioxidant status was not elevated in antioxidant group. Antioxidant supplementation did not change the serum levels of P-selectin, MCP-1, IL-6 and IL-10. The 6-month angiographic in-stent restenosis rate was 27% versus 30% (p=NS) with an associated late loss of 0.76±1.01 mm versus 0.91±1.00 mm (p=NS) for antioxidant group and control group. The serum levels of total antioxidant status did not correlate with the restenosis or late loss after stent implantation. Conclusions : Vitamin C, E and probucol did not elevate the serum level of antioxidant status and could not prevent in-stent restenosis after bare metal stent implantation.(Korean J Med 71:158-165, 2006)
