Biomarkers of platelet activation and cardiovascular risk in the DAPT trial.

ABSTRACT: Prolonged use of dual antiplatelet therapy (DAPT) post-percutaneous coronary intervention (PCI) has been shown to reduce the risk of major adverse cardiovascular events (MACE), but with increased bleeding. It remains unknown whether biomarkers of platelet activation may be useful for identifying patients at increased risk of MACE. The DAPT study was a randomized trial of 12 versus 30 months of DAPT in patients who underwent PCI. Serum biomarkers [myeloid-related protein (MRP)-8/14, P-selectin, soluble CD-40 ligand (sCD40L)] were assessed in 1399 patients early post-PCI. On-treatment platelet reactivity index (PRI) using VASP phosphorylation was assessed in 443 patients randomized to continued DAPT at 1 year. MACE was defined as CV death, MI, or ischemic stroke. Multivariable models were ad
