Long-Term Vascular Function in CTO Recanalization: A Randomized Clinical Trial of Ticagrelor vs. Clopidogrel
Abstract
Background
Coronary vascular function of a chronic coronary total occlusion (CTO) immediately after recanalization is known to be poor and to be partially improved by pre-treatment with loading dose of ticagrelor vs. clopidogrel. It is unknown if this vascular dysfunction is maintained at long-term follow-up and may be improved by 1-year dual antiplatelet therapy (DAPT).
