PRIMARY outcome

Timeframe: 30 days

Population: 130 patients were randomized and exposed to at least one dose of study medication (triple therapy, n=44; dual therapy, n= 43; DAPT, n=43). Of these, 115 patients (triple therapy, n=37; dual therapy, n= 39; DAPT, n=39) had valid primary endpoint data

The primary end point of our study is the comparison of maximal platelet aggregation measured by light transmittance aggregometry using CAT (collagen-ADP-TRAP) between DAPT and DAPT plus vorapaxar after 30 days of treatment.
