Abstract
The number of patients with diabetes with a risk of cardiovascular diseases (CVDs) is increasing worldwide, leading to a higher demand for evaluating atherosclerosis. Recently, the mean platelet volume (MPV) available from complete blood count is gaining attention as a marker of underlying atherosclerotic lesions. In the current study, we examined whether MPV can predict carotid atherosclerosis in patients with diabetes at an intermediate or high risk for CVD. A total of 224 patients with diabetes aged 36-85 years who underwent carotid ultrasound examination were assessed. The risk of CVD was evaluated using the Suita score. The greatest carotid intima-media thickness (IMT) in each common carotid artery (CCA Max-IMT), carotid bulb, internal carotid artery, or external carotid artery (Total Max-IMT) was measured. Subsequently, the relationship between MPV and IMT was analyzed. Patients were divided into three groups according to their MPV values (<9.5 fl, tertile 1; 9.5-10.2 fl, tertile 2; and >10.2 fl, tertile 3). A correlation was observed between MPV and platelet count (P < 0.001), platelet distribution width (P < 0.001), and glycated hemoglobin (P = 0.04); however, multivariate logistic regression analyses demonstrated no relationship between MPV and CCA Max-IMT [odds ratio, 0.89 (0.60-1.29), P = 0.54] or Total Max-IMT [odds ratio, 0.87 (0.61-1.24), P = 0.45]. MPV did not correlate with carotid artery thickness. Therefore, it is difficult to determine the significance of MPV in atherosclerotic conditions from this study.
