Increased mean platelet volume is associated with arterial stiffness

Area of Science:

• Cardiovascular Research
• Hematology
• Biomarker Discovery

Background:

• Arterial stiffness, measured by brachial-ankle pulse wave velocity (baPWV), is a significant predictor of cardiovascular events.
• Mean platelet volume (MPV), a marker of platelet activation, is linked to conditions such as hypertension and stroke.
• The relationship between MPV and arterial stiffness remains under-researched.

Purpose of the Study:

• To investigate the association between platelet count, MPV, and baPWV in a large cohort of apparently healthy Chinese adults.
• To determine if MPV is an independent predictor of arterial stiffness.

Main Methods:

• A cross-sectional study involving 2645 apparently healthy Chinese participants.
• Analysis of demographic, metabolic, and hematological parameters, including platelet count and MPV.
• Statistical analysis, including univariate and multivariate models, to assess the relationship between MPV and baPWV.

Main Results:

• Mean baPWV values showed a gradual increase across increasing MPV quintiles.
• Univariate analysis identified age, sex, BMI, SBP, FPG, platelet count, and MPV as significantly associated with baPWV.
• Multivariate analysis confirmed MPV as a significant independent determinant of baPWV (β=0.198; P<0.001).

Conclusions:

• Elevated MPV is positively correlated with increased arterial stiffness (baPWV).
• MPV may serve as a valuable, accessible biomarker for assessing arterial stiffness and cardiovascular risk in apparently healthy populations.
• Further research is warranted to explore the clinical implications and mechanistic links between MPV and vascular health.
