This study found that diabetic patients have significantly higher platelet reactivity and a higher prevalence of high platelet reactivity after percutaneous cutaneous intervention. High platelet reactivity is associated with an increased risk of major adverse cardiac and cerebrovascular events in diabetic patients, but not in non-diabetic patients.
Background Diabetes mellitus (DM) is associated with thrombogenicity, clinically manifested with atherothrombotic events after percutaneous cutaneous intervention (PCI). This study aimed to investigate association between DM status and platelet reactivity, and their prognostic implication in PCI-treated patients. Methods The Platelet function and genoType-Related long-term Prognosis-Platelet Function Test (PTRG-PFT) cohort was established to determine the linkage of platelet function test (PFT) with long-term prognosis during dual antiplatelet therapy including clopidogrel in patients treated with drug-eluting stent (DES). We assessed platelet reactivity using VerifyNow and 'high platelet reactivity (HPR)' was defined as >= 252 P2Y12 reaction unit (PRU). Major adverse cardiac and cerebrovascular event (MACCE) was a composite of all-cause death, myocardial infarction, stent thrombosis or stroke. Results Between July 2003 and Aug 2018, DES-treated patients with available PFT were enrolled (n = 11,714). Diabetic patients demonstrated significant higher levels of platelet reactivity (DM vs. non-DM: 225.7 +/- 77.5 vs. 213.6 +/- 79.1 PRU, P < 0.001) and greater prevalence of HPR compared to non-diabetic patients (38.1% vs. 32.0%, P < 0.001). PRU level and prevalence of HPR were significantly associated with insulin requirement and Hb(A1c) level, as well as diabetic status. DM status and HPR phenotype had a similar prognostic implication, which showed the synergistic clinical impact on MACCE. Association between PRU level and MACCE occurrence seemed higher in diabetic vs. non-diabetic patients. In non-DM patients, HPR phenotype did not significantly increase the risk of MACCE (adjusted hazard ratio [HRadj]: 1.073; 95% confidence interval [CI]: 0.869-1.325; P = 0.511), whereas HPR was an independent determinant for MACCE occurrence among diabetic patients (HRadj: 1.507; 95% CI: 1.193-1.902; P < 0.001). Conclusion The levels of on-clopidogrel platelet reactivity are determined by diabetic status and the severity of DM. In addition, HPR phenotype significantly increases the risk of MACCE only in diabetic patients.
