Gender Differences in Vascular Compliance in Young, Healthy Subjects Assessed by Pulse Contour Analysis
Why the study?
Does female gender affect vascular compliance in young, healthy subjects compared to male gender?
Population
151 young, healthy, predominantly nonsmoking, medication-free men and women, mean age 24+/-4 years.
Comparison
Female gender (observational) vs Male gender
Design
Cross-sectional

Implication
Does not support sex-specific vascular screening in young adults; leaves open hormonal effects on compliance and requires prospective validation.

O
Outcome
Large (C1) and small (C2) vessel compliance derived from arterial pulse wave contour analysissurrogate
Young, healthy women demonstrate reduced small vessel compliance compared to men despite having more favorable cardiovascular risk profiles, suggesting potential negative effects of female sex hormones on small resistance vessels.
