“…To date, only persistent use of statin therapy and β blockers have been shown to reduce intimal hyperplasia in SVGs (9) while Edifoligide (8) and aspirin + clopidogrel (10), have both failed to do so, respectively, at 12-18 months after CABG. Mechanical external stents for SVGs have shown considerable promise in pre-clinical testing with reduction of proliferative intimal hyperplasia by reducing wall tension, improving lumen uniformity and creating a protective "neo-adventitia" layer rich with micro vasculature (11)(12)(13).…”
