Gender differences in artery wall biomechanical properties throughout life

Area of Science:

• Cardiovascular physiology
• Biomedical engineering
• Endocrinology

Background:

• Elevated large artery stiffness and pulse pressure are key cardiovascular disease risk factors.
• Significant gender disparities exist in large artery biomechanical properties across the lifespan.
• Females exhibit higher arterial stiffness prepuberty and a sharp increase postmenopause, unlike males.

Purpose of the Study:

• To review the influence of anthropometrics and sex steroids on gender differences in large artery stiffness.
• To explore sex-specific effects of estrogen, progesterone, and testosterone on vascular function.
• To understand how these factors contribute to cardiovascular disease pathophysiology and clinical presentation differences between genders.

Main Methods:

• Literature review synthesizing existing research on arterial stiffness and sex differences.
• Analysis of data concerning anthropometric measurements and sex hormone levels.
• Exploration of studies investigating vascular structure and function in relation to sex steroids.

Main Results:

• Females display intrinsically stiffer arteries than males, a difference modulated by sex steroids during reproductive years.
• Males experience a postpubertal increase in arterial stiffness, followed by a linear progression.
• Estrogen, progesterone, and testosterone significantly impact vascular structure and function, influencing arterial stiffness differently between genders.

Conclusions:

• Sex steroids play a crucial role in modulating gender-specific arterial stiffness and pressure dynamics.
• Understanding these sex-specific mechanisms is vital for addressing cardiovascular disease disparities.
• Further research into hormonal influences can refine cardiovascular disease prevention and treatment strategies.
