球囊血管成形术后，血管内皮受损和扩张性损伤弓l发机体一系列生物学反应，血管平滑肌细胞（Vascu－larsmoothmusclecell，VSMC）增殖并向内膜下移行，形成扩张血管段的再狭窄。在此过程中，有多种血管活性肽参与。国内外研究已证实，降钙素基因相关肽（Caf－citoningene－rela
After balloon angioplasty, vascular endothelial damage and dilatation injury bow l a series of biological reactions in the body, vascular smooth muscle cells (Vascu-larsmoothmusclecell, VSMC) proliferation and submucous migration, the formation of dilatation of vascular restenosis . In the process, there are a variety of vasoactive peptides involved. Domestic and foreign studies have confirmed that calcitonin gene-related peptide (Caf-citoningene-rela
