Sex-Specific Patterns in Blood Pressure and Vascular Parameters: The MUJER-EVA Project.

Recent evidence suggests that sex-related differences in cardiovascular health extend beyond traditional risk factors, affecting vascular structure and function. This study aimed to examine sex differences in vascular parameters, including central and peripheral blood pressure, pulse wave velocity (PWv), augmentation index at 75 bpm (AIx75), cardiac output, stroke volume, and peripheral vascular resistance, using harmonized data from three population-based cohorts (EVasCu, VascuNET, and ExIC-FEp) as part of the MUJER-EVA project. A total of 669 adult participants were included in this pooled cross-sectional analysis. Sex-stratified comparisons were conducted using multiple linear regression models adjusted for anthropometric, sociodemographic, and clinical covariates. The results showed that men had significantly higher values for central and peripheral blood pressure ( < 0.001), PWv ( = 0.003), cardiac output ( < 0.001), and stroke volume ( < 0.001), whereas women presented higher values of AIx75 ( < 0.001) and peripheral vascular resistance ( = 0.002). These differences remained statistically significant after full adjustment for potential confounders. These findings highlight the need to consider sex as a key biological variable in cardiovascular research and clinical decision-making. Incorporating sex-specific reference values and personalized treatment strategies could improve vascular health assessment and the effectiveness of cardiovascular disease prevention.
