Objectives: This research aims to investigate whether there is an association between acute hyperglycemia and diabetes mellitus and the amount of circulating platelet-derived microparticles (PDMPs) during acute myocardial infarction (AMI) initial episode. Methodology: This was a cross-sectional study. Subjects were AMI patients underwent hospitalization. Demography and clinical data were obtained from hospital records. Diabetes mellitus was defined from history of disease, antidiabetic use and/or level of HbA1C ≥6.5%. Levels of HbA1c, admission random and fasting blood glucose levels were measured in hospital laboratory. The PDMPs was measured by flow-cytometry method, by tagging with CD-41 FITC and CD-62 PE markers and threshold size of <1 µm, from venous blood. The circulating PDMPs amount was compared according to glucometabolic state, namely acute hyperglycemia (admission random glucose ≥200 mg/dL and fasting glucose ≥140 mg/dL) and diabetes mellitus. The comparative analysis between group was conducted with Student T tests or Mann-Whitney tests, where applicable. Results: A total of 108 subjects were included and their data analyzed. Circulating PDMPs amount was significantly lower in subjects with admission random glucose ≥200 mg/dL as compared to those with below level (median (interquartile range (IQR)): 2,710.0 (718.0-8,167.0) count/mL vs. 4,452.0 (2,128.5-14,499.8) count/mL, p=0.05) and in subjects with fasting glucose ≥140 mg/dL as compared to those with below level (median (IQR): 2,382.0 (779.0-6,619.0) count/mL vs. 5,972.0 (2,345.7-14,781.3) count/mL, p=0.006). Circulating PDMPs amount was also significantly lower in diabetes mellitus as compared to non diabetic (median (IQR): 2,655.0 (840.0-5,821.0) count/mL vs. 4,562.0 (2,128.5-15,055.8) count/mL; p=0.007). Conclusion Acute hyperglycemia and diabetes mellitus significantly associated with lower amount of circulating PDMPs during the initial episode of AMI.
