Letter by Nezami et al Regarding Article, “Platelet Reactivity and Cardiovascular Outcomes After Percutaneous Coronary Intervention: A Time-Dependent Analysis of the Gauging Responsiveness With a VerifyNow P2Y12 Assay: Impact on Thrombosis and Safety (GRAVITAS) Trial”

To the Editor: Price et al1 have reported the results of the Gauging Responsiveness With a VerifyNow P2Y12 Assay: Impact on Thrombosis and Safety (GRAVITAS) trial in patients who had undergone percutaneous coronary intervention with ≥1 drug-eluting stents for the treatment of stable coronary artery disease or acute coronary syndrome at 83 sites in the United States and Canada. They reported that achievement of on-clopidogrel reactivity <208 P2Y12 reaction units at 12 to 24 hours after …
