Platelet Indices in Patients with Type 2 Diabetes Mellitus Undergoing Percutaneous Coronary Intervention

Acta Endo (Buc) 2021, 17 (4): 543-547

Context. Platelet indices change in relation to cardiovascular risk factors, including type 2 diabetes mellitus (T2DM). An increase of platelet indices over time in patients undergoing percutaneous coronary intervention (PCI) could be a predictor of mortality. The objective of this study was to assess differences in platelet indices in patients with and without T2DM undergoing PCI, prior and more than one month after the procedure. Subjects and Methods. In this retrospective observational study, patients undergoing PCI were included. Data were extracted from PCI Registry of the Emergency Institute for Cardiovascular Diseases and Transplantation of Tirgu Mures, Romania. Results. Of the 718 patients included in the study, 222 (30.9%) had T2DM; 61% of patient underwent PCI for SCAD, the rest for NSTE-ACS or STEMI. Prior to PCI, MPV, PDW and P-LCR were not higher in T2DM patients irrespective of the indication for PCI. At a follow-up time of 69 (46-98) days, platelet indices were not different between TD2M+ and T2DM-, except from MPV (11.0 vs. 10.6, p=0.02) which were higher in TD2M patients with SCAD. Intraindividual variability of platelet indices was not different in diabetics, but MPV, PDW and platelet count decreased over time (3.5% and 8.4% respectively) in diabetics with STEMI (p=0.02). Conclusions. Platelet indices were not higher in patients with T2DM undergoing PCI, but we observed an important variation in platelet indices in diabetics after STEMI related PCI.
