Gender difference in adiponectin associated with cardiovascular mortality.

Area of Science:

• Cardiology
• Genetics
• Endocrinology

Background:

• Identifying high-risk cardiovascular disease (CVD) patients is crucial.
• Integrating genetic analysis into routine cardiology is under consideration.
• Adiponectin's role in cardiovascular risk requires further elucidation.

Purpose of the Study:

• To assess the association between high-molecular weight adiponectin and cardiovascular risk.
• To investigate genotype differences in cardiovascular risk within the study population.
• To explore potential gender-specific differences in adiponectin-related cardiovascular risk.

Main Methods:

• A cohort of 476 elderly individuals from a rural community was studied.
• Participants underwent clinical examination, echocardiography, and blood sampling.
• Adiponectin single nucleotide polymorphism (SNP) rs266729 was analyzed, with a 6.7-year follow-up.

Main Results:

• Elevated serum adiponectin concentrations were linked to a twofold increase in cardiovascular risk.
• Females with high adiponectin showed a greater than fivefold increased risk, even after adjusting for clinical factors.
• In females, the adiponectin C/C genotype (rs266729) was associated with a ninefold higher risk of cardiovascular mortality, a finding not observed in males.

Conclusions:

• High adiponectin levels are significantly associated with increased cardiovascular risk.
• A notable gender difference was observed in genotype-related risk, with C/C carriers showing higher risk in females.
• Genetic analysis, particularly in females, may offer a valuable tool for early cardiovascular risk stratification, though findings require further validation in larger studies.
