  • Title: [Pathophysiology of restenosis following percutaneous transluminal coronary angioplasty].
    Author: Holm AM, Haunsø S, Hansen PR.
    Journal: Ugeskr Laeger; 1998 Feb 23; 160(9):1302-6. PubMed ID: 9495077.
    Abstract:
    Symptomatic restenosis occurs in approximately 30-40% of patients after percutaneous transluminal coronary angioplasty (PTCA). Despite intensive research, the primary pathophysiological mediators have not been defined, and pharmacological therapy has not been effective in preventing restenosis. Restenosis is a multifactorial and sequential process, which is initiated by mechanical injury of the vessel wall, and involves neointima formation caused by the local proliferation of smooth muscle cells and production of an extracellular matrix, followed by vascular remodelling. Numerous mediators are involved in these processes, e.g., protooncogenes, growth factors, cytokines and nitric oxide. This review discusses the pathobiological mechanisms underlying coronary restenosis, and outlines the prospects for future therapy.
