No obvious association exists between mean platelet volume and hypertension subtypes

Abstract

Aims: To determine the association between mean platelet volume (MPV) and hypertension subtypes. Participants & results: 44,281 Chinese individuals were enrolled in this cross-sectional study. The mean blood pressure decreased with increasing MPV in females (p = 0.001) and increased MPV seemed to be a potential protective factor for isolated diastolic hypertension in models 1 and 2. The OR (CI) was 0.878 (0.789–0.976) for model 1 and 0.880 (0.789–0.981) for model 2 in males and 0.646 (0.495–0.841) for model 1 and 0.657 (0.503–0.858) for model 2 in females, when MPV was analyzed as a categorical variable. The OR (CI) was 0.947 (0.911–0.985) for Model 1 and 0.947 (0.910–0.985) for Model 2 in males, and 0.886 (0.807–0.973) for Model 1 and 0.892 (0.813–0.978) for Model 2 in females when MPV was analyzed as a continuous variable. However, the statistical difference of OR disappeared when we added blood-related covariates in Model 3. Conclusion: No obvious association exists between MPV and hypertension subtypes. Other blood parameters might have a greater impact on hypertension subtypes.
