Sex Differences in Cardiovascular Diseases and Vascular Function in Chronic Kidney Disease

Area of Science:

• Nephrology
• Cardiology
• Endocrinology
• Vascular Biology

Background:

• Cardiovascular disease (CVD) is the primary cause of mortality in patients diagnosed with chronic kidney disease (CKD).
• Understanding sex-based disparities in CVD risk and vascular dysfunction within the CKD population is critical for targeted interventions.
• Existing research indicates significant differences in how CKD affects cardiovascular health between biological sexes.

Purpose of the Study:

• To synthesize current knowledge on sex differences in cardiovascular disease (CVD) and vascular dysfunction among patients with chronic kidney disease (CKD).
• To explore potential mechanisms contributing to sex-based variations in cardiovascular risk in CKD.
• To identify research gaps and challenges concerning sex differences in CVD risk and women's vascular health in CKD, proposing future research directions.

Main Methods:

• Literature review and synthesis of existing research on sex differences in CKD and CVD.
• Analysis of potential mechanistic links, including CKD progression, the hypothalamic-pituitary-gonadal axis, and gonadal hormone production.
• Identification and discussion of current research limitations and future research strategies.

Main Results:

• Significant sex differences exist in cardiovascular disease (CVD) risk and vascular dysfunction in patients with chronic kidney disease (CKD).
• Mechanisms such as differential CKD progression impacting the hypothalamic-pituitary-gonadal axis and gonadal hormone levels may contribute to these sex disparities.
• Research on women's vascular health and sex differences in CVD risk within the CKD population remains incomplete, with notable gaps and challenges.

Conclusions:

• Sex differences play a crucial role in cardiovascular disease (CVD) risk and vascular dysfunction in chronic kidney disease (CKD) patients.
• Further research is imperative to elucidate the specific mechanisms driving these sex disparities and to improve cardiovascular outcomes for all CKD patients.
• Addressing research gaps, particularly concerning women's vascular health, is essential for advancing personalized and effective CKD management strategies.
