Ticagrelor versus clopidogrel for recovery of vascular function immediately after successful chronic coronary total occlusion recanalization: A randomized clinical trial

Abstract Coronary vascular function of a chronic coronary total occlusion (CTO) immediately after recanalization is known to be poor. We sought if ticagrelor may augment adenosine-induced coronary blood flow vs. clopidogrel immediately after successful CTO percutaneous coronary intervention (PCI).
