PCI with coronary stenting should not be performed if the patient is not likely to be able to tolerate and comply with DAPT.208 211 (Level of Evidence: B) 2. DES should not be implanted if the patient is not likely to be able to tolerate and comply with prolonged DAPT or this cannot be determined before stent im- plantation.208,460 462 (Level of Evidence: B) Coronary stent implantation is commonly performed during PCI to prevent recoil, abrupt closure, and late restenosis.463,464 BMS are composed of either stainless steel or cobalt chro- mium alloys. Because the risk of stent thrombosis is greatest within the first 30 days after implantation, the use of DAPT is required for 30 days after implantation of BMS.208 In the United States, 4 types of DES are currently ap- proved: sirolimus-eluting stents, paclitaxel-eluting stents, zotarolimus-eluting stents, and everolimus-eluting stents. DES vary according to stent scaffold material and design, drug content, and the polymer used for drug elution; however, several common clinical features are present.
