Class I Guidelines

 * 1) A DES should be considered as an alternative to a BMS in those patients for whom clinical trials indicate a favorable effectiveness/safety profile. (Class I Level of Evidence: A)
 * 2) Before implanting a DES, the interventional cardiologist should discuss with the patient the need for and duration of dual antiplatelet therapy and confirm the patient’s ability to comply with the recommended therapy for DES. (Class I Level of Evidence: B)
 * 3) In patients who are undergoing preparation for PCI and are likely to require invasive or surgical procedures for which dual antiplatelet therapy must be interrupted during the next 12 months, consideration should be given to implantation of a BMS or performance of balloon angioplasty with a provisional stent implantation instead of the routine use of a DES. (Class I Level of Evidence: C)
