Higher Cardiovascular Health Scores Linked to Lower Mortality in Postmenopausal Women
A recent study has documented an inverse association between higher scores on the American Heart Association's Life's Essential 8 (LE8) and Life's Crucial 9 (LC9) cardiovascular health metrics and lower risks of all-cause and cardiovascular mortality in postmenopausal women. The research, published in Menopause, the journal of The Menopause Society, also indicated that adiposity-related and inflammation-related indicators partially mediated these observed associations.
Understanding Cardiovascular Health in Postmenopausal Women
Cardiovascular disease remains a primary cause of morbidity and mortality globally. For women, the risk of developing cardiovascular disease increases significantly after menopause, a period characterized by hormonal shifts, metabolic changes, and vascular aging. Comprehensive assessment of cardiovascular health is considered essential for identifying populations at high risk and for developing targeted prevention strategies for postmenopausal women.
The American Heart Association's LE8 and LC9 metrics are designed to summarize overall cardiovascular health. While previous research has established links between higher LE8 and LC9 scores and reduced risks of cardiovascular events and mortality, the specific underlying causes for these associations had not been fully identified. This study aimed to examine these relationships further and evaluate the statistical mediation by adiposity-related and inflammation-related indicators. Postmenopausal women frequently experience changes in body composition and fat redistribution, which can elevate cardiometabolic risk, with higher adiposity often associated with increased inflammatory markers and metabolic dysregulation in this demographic.
Research Uncovers Mediating Factors
The study involved more than 7,800 postmenopausal women, during which 1,313 deaths were recorded among the participants. Researchers examined the relationships between LE8 and LC9 scores and both all-cause and cardiovascular mortality. They also evaluated whether adiposity-related and inflammation-related indicators statistically mediated these associations.
Key findings include:
- Higher LE8 and LC9 scores were associated with lower risks of all-cause mortality in postmenopausal women.
- Higher LE8 and LC9 scores were associated with lower risks of cardiovascular mortality in postmenopausal women.
- Adiposity-related and inflammation-related indicators were found to partially mediate these associations.
Implications for Postmenopausal Health
These findings highlight the importance of comprehensive cardiovascular health assessment in postmenopausal women and suggest that maintaining favorable cardiometabolic profiles may offer benefits.
Dr. Stephanie Faubion, medical director for The Menopause Society, noted that the study's findings underscore the impact of lifestyle factors on heart health. She indicated that women with better overall cardiometabolic health profiles after menopause are observed to have a higher likelihood of living longer.
