The relationship between mean platelet volume and reverse dipping blood pressure pattern in patients with essential hypertension.

Objective An association between increased mean platelet volume (MPV) and cardiovascular events is well established. Recent studies suggest that a nondipper blood pressure pattern is closely related to increased MPV. Because little information has been revealed about the relationship between reverse dipper hypertension (RDHT) and MPV, we aimed to investigate this relation. Methods A total of 317 patients were retrospectively evaluated by analyzing the records of ambulatory blood pressure monitoring (ABPM). Patients were categorized into three groups according to their ABPM values as RDHT (n = 63), non-dipper hypertension (NDHT) (n = 95), and dipper hypertension (DHT) groups (n = 159). MPV and biochemical analyses were recorded from the hospital database. Results The largest MPV was found in patients with RDHT, followed by patients with NDHT and DHT group (9.1 ± 0.4 fl, 8.8 ± 0.6 fl, and 8.6 ± 0.5 fl, respectively, for all p 9,1 fl with a sensitivity of 60% and specificity of 69%, respectively (AUC = 0.696 ± 0.035, 95% CI: 0.627-0.764). Our data show that the RDHT pattern is associated with increased MPV values in patients with essential hypertension.
