Modestly overweight women have vascular endothelial dysfunction.

Area of Science:

• Cardiovascular Health
• Vascular Biology
• Preventive Medicine

Background:

• Vascular endothelial dysfunction is an early indicator in atherosclerosis and predicts cardiovascular prognosis.
• The link between specific cardiovascular risk factors and endothelial dysfunction in women is not well understood.
• This study investigated endothelial dysfunction in relation to common cardiovascular risk factors in women, including those undergoing treatment.

Purpose of the Study:

• To examine the relationship between endothelial dysfunction and cardiovascular risk factors in women.
• To identify predictors of endothelial dysfunction in a female population.
• To assess the impact of risk factors like BMI, smoking, and age on vascular health.

Main Methods:

• Assessed endothelial function using brachial artery ultrasound flow-mediated vasodilation (FMD).
• Included 185 women without a history of coronary heart disease.
• Allowed participants with hypertension, diabetes, or hyperlipidemia to continue their prescribed therapies.

Main Results:

• Found an inverse linear association between age and FMD.
• Active smokers and women with a body mass index (BMI) >= 25 kg/m(2) exhibited lower FMD.
• Multivariate analysis identified BMI, current smoking, and age as independent predictors of endothelial dysfunction.

Conclusions:

• Modestly elevated BMI, smoking, and age are significant predictors of endothelial dysfunction in women.
• These findings emphasize the role of even modest BMI elevation in impairing vascular health.
• Underscores the importance of lifestyle modifications for cardiovascular disease prevention in women.
