Association of Acute Hyperglycemia and Diabetes Mellitus with Platelet-derived Microparticle (PDMP) Levels During Acute Myocardial Infarction.

This research investigates whether there is an association between acute hyperglycemia and diabetes mellitus and the level of circulating platelet-derived microparticles (PDMPs) during an initial episode of acute myocardial infarction (AMI). This was a cross-sectional study involving hospitalized AMI patients. Demographic and clinical data were obtained from hospital records. Diabetes mellitus was defined by the history of the disease, anti-diabetes medication use and/ or level of HbA1C ≥6.5%. Levels of HbA1c, admission random and fasting blood glucose levels were measured. Flow-cytometry method was used to determine the levels of PDMPs from collected venous blood through tagging with CD-41 FITC and CD-62 PE markers and a threshold size of <1 μm. The number of circulating PDMPs 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 groups was conducted with Student T-test or Mann-Whitney test, where applicable. A total of 108 subjects were included and their data analyzed. The level of circulating PDMPs 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, Acute hyperglycemia and diabetes mellitus are significantly associated with a lower circulating PDMP level during an initial AMI episode.
