Obesity and cardiovascular disease in women

Area of Science:

• Cardiovascular Science
• Endocrinology
• Women's Health

Background:

• Rising global obesity rates contribute to a significant health and financial burden from related comorbidities.
• Cardiovascular disease (CVD) is strongly linked to increased adiposity, with women facing a disproportionately higher risk.
• Obese women, particularly those with insulin resistance, exhibit elevated risks for heart failure with preserved ejection fraction and ischemic heart disease.

Purpose of the Study:

• To review evidence on the differential cardiovascular impact of adiposity in women versus men.
• To explore proposed pathophysiological mechanisms underlying these sex-specific differences.
• To discuss women-specific risk factors for CVD in the context of obesity and insulin resistance.

Main Methods:

• Literature review of existing evidence.
• Analysis of proposed pathophysiological mechanisms.
• Discussion of epidemiological data and clinical observations.

Main Results:

• Obesity presents unique cardiovascular risks for women, differing from those in men.
• Mechanisms include altered aldosterone, mineralocorticoid receptor activation, estrogenic signaling, and androgen levels.
• Women-specific factors like pregnancy weight gain, preeclampsia, gestational diabetes, and menopause exacerbate CVD risk.

Conclusions:

• Understanding sex-specific impacts of obesity on cardiovascular health is crucial.
• Targeted interventions considering women's unique risk factors are needed to combat the CVD epidemic.
• Further research into the mechanisms driving differential CVD risk in obese women is warranted.
