Heart fat and carotid artery atherosclerosis progression in recently menopausal women: impact of menopausal hormone therapy: The KEEPS trial.

OBJECTIVE: Heart fat deposition has been linked to atherosclerosis, and both accelerate after menopause. Hormone therapy (HT) may differentially slow heart fat deposition and progression of atherosclerosis, depending on the specific HT agent or its route of administration. Our objective was to evaluate the effects of different HT agents, oral and transdermal, on associations between heart fat accumulation and atherosclerosis progression, measured by carotid intima-media thickness (CIMT), in recently menopausal women from the Kronos Early Estrogen Prevention Study (KEEPS) trial. METHODS: KEEPS was a randomized, placebo-controlled trial of the effects of 0.45 mg/d oral conjugated equine estrogens (o-CEE) or 50 mcg/d transdermal 17ß-estradiol (t-E2), compared with placebo, on 48 months progression of CIMT. Epicardial adipose tissue (EAT) and paracardial adipose tissue (PAT) volumes were quantified by computed tomography. RESULTS: In all, 467 women (mean age [SD] 52.7 [2.5]; 78.2% White; 30% on o-CEE, 30.8% t-E2, 39.2% placebo) with heart fat volumes and CIMT at baseline and 48 months were included. EAT and PAT changes were not associated with CIMT progression; however, the assigned treatment significantly modified the association between PAT (but not EAT) change and CIMT progression. In the o-CEE group, adjusted CIMT progression was 12.66 µm (95% confidence interval [CI] 1.80, 23.52) lower than in t-E2 group (P = 0.02), and 10.09 µm (95% CI 0.79, 19.39) lower than in placebo group (P = 0.03), as per 1-SD increase in PAT. CONCLUSION: Compared with t-E2, o-CEE appears to slow down the adverse effect of increasing PAT on progression of atherosclerosis. Whether this beneficial association is specific to CEE or to the oral route of CEE administration is unclear and should be assessed further.

Brain health and cognitive and mood disorders in ageing women.

Improved medical, economic and socio-cultural conditions have increased life expectancy, especially for women. The incidence of hypertension, diabetes mellitus, psychiatric and degenerative brain diseases, especially stroke and dementia, are more frequently seen in older people. Each of these conditions can separately, or in combination, result in similar signs and symptoms of cognition, memory, mood and motor function disorders. Therefore, it is important to understand the effects of normal ovarian ageing and the menopause on the nervous system, as well as the hallmarks of disease entities; many of these are described here. Also, the complexity of these issues is increased by the similarity of their effects to those of the polypharmacy and metabolic imbalances that are common in this population. These are complex issues, and it may be difficult and time-consuming to discern between normal brain functional changes and specific pathology in practice. Early evaluation of correctable possibilities, including imaging studies, may be key to management. Referral to specialists for diagnosis before starting clinical treatment is useful to address these issues.
