Abstract: In randomized clinical trials, ticagrelor has been substituted in roughly one-third of the patients during follow-up. To date, there are no studies addressing safety and modalities of switching from ticagrelor to clopidogrel. The aim of our study is to describe the occurrence, causes, and outcome of the switch from ticagrelor to clopidogrel in a real-life scenario. From June 2013 to March 2015, 586 patients were treated with ticagrelor in our centre. Overall, 101 (17%) patients were switched to clopidogrel through a standardized protocol, and they were followed-up for 12 months. Ischemic and bleeding events were prospectively recorded. The switch from ticagrelor to clopidogrel occurred mostly after discharge (69 ± 40 days), and the most frequent cause was the need of oral anticoagulation treatment, followed by bleeding events. Patients requiring ticagrelor discontinuation were older, more frequently female, with lower body mass index and creatinine clearance if compared to the “non-switched” group. In the 10 days after the switch, we did not observe ischemic adverse events. No definite/probable stent thrombosis was recorded. Before the switch, there was a significant higher occurrence of BARC bleedings in the “switched” group, particularly BARC 1 and 2. Our data confirm that the switch from ticagrelor to clopidogrel is common, and it occurs for several reasons. Our analysis did not demonstrate a significant increase in adverse cardiovascular events in the days following the switch from ticagrelor to clopidogrel, although larger studies are needed to validate our findings.
