“…[12][13][14] In the trial by Dreifaldt and colleagues, 3 more than 60% of radial targets had less than 90% stenosis, with approximately 33% of the RAs targeted to a less than 70% stenotic vessel. 2,3 Furthermore, the media of the RA is 1.7-fold thicker than the internal thoracic artery, increasing its propensity for contractility. 15 Thus, it is encouraged to minimize alpha-adrenergic agents perioperatively if possible 16 and use calcium channel blockers (CCBs) at discharge for longitudinal protection.…”
