| Popis: | Background Ticagrelor presents less thrombotic risk compared to clopidogrel in acute coronary syndromes. However, its role in dual antiplatelet therapy (DAPT)-naive patients with stable ischemic heart disease (SIHD) undergoing elective percutaneous intervention (PCI) remains unclear, including uncertainty in the method of conversion to clopidogrel for adequate coverage without increased bleeding risk. Objective Determine the safety and efficacy of ticagrelor loading and transitioning to clopidogrel in patients with SIHD undergoing elective PCI. Methods This is a retrospective cohort review of patients with SIHD who underwent elective PCI. The Switch Rx patients were treated with ticagrelor immediately before PCI, converted to clopidogrel 300 mg the day after, and discharged with clopidogrel 75 mg daily. Standard Rx patients, who received a clopidogrel load and received clopidogrel 75 mg daily after the procedure, were analyzed as a matched comparator cohort. The safety outcomes were any bleeding event at 24 hours and 30 days. The efficacy outcomes included major adverse cardiac events (MACE) at 24 hours and 30 days. Results Five Switch Rx patients (n = 54) experienced bleeding academic research consortium type I bleeding within 24 hours, with no subsequent bleeding observed out to 30 days. When comparing the Switch Rx patients (n = 39) to their matched Standard Rx cohort (n = 39), no MACEs occurred within 30 days and there were no significant differences in safety and efficacy outcomes. Conclusion In DAPT-naive patients undergoing elective PCI for SIHD, a strategy of in-lab ticagrelor transitioning to clopidogrel with a 300-mg load was not associated with increased bleeding or other adverse events. |
