Temporal Trends in the Use of Antiplatelet Therapy in Patients With Acute Coronary Syndromes.

Background: Current clinical guidelines of acute coronary syndromes (ACS) recommend the use of potent antiplatelet therapy, prasugrel or ticagrelor, because both drugs consistently reduce cardiovascular events.

Purpose: The aim of this study was to examine temporal changes in the use of optimal antiplatelet therapy in patients with ACS.

Methods: A total of 1717 consecutive patients admitted for ACS in 3 tertiary hospitals from February 2014 to December 2015 were enrolled.
