But there are partial patients who have the possibility of re-stenosis. This paper had discussed about coronary artery stenosis in the mechanism, happening time, correlative factors and pathogenesis. The relationship between matrix metallo proteinase, fibrinolysin system and re-stenosis of coronary artery were also investigated.
