Objectives: To date studies evaluating the relation between circulating aldosterone levels and mortality in elderly female individuals are lacking. We therefore aimed to assess the relationship between circulating aldosterone levels and mortality in a population-based cohort study of female nursing home residents.
Methods: Individuals aged 70years and older were recruited from 95 nursing homes in Austria. Participants were enrolled and followed up by mobile study teams. All participants underwent an extensive health examination and were followed until death or end of the study. Serum aldosterone concentration (SAC) was measured at baseline after exclusion of twenty seven patients taking mineralocorticoid-receptor (MR) blockers.
Results: Median SAC was 171.1 (IQR: 103.2-303.4) pg/mL (normal range: 30-400) in 471 female individuals (mean age: 83.7±6.2years). After a median follow-up of 27±8months, a total of 121 (25.7%) participants died. In multivariable Cox proportional hazard analysis, SAC levels stratified in quartiles were significantly associated with all-cause mortality. Compared with the reference (first) SAC quartile, the Cox proportional hazard ratio (confidence interval 95%) for the fourth SAC quartiles was 1.94, 95% CI=1.08-3.46, p=0.026. We found statistically significant interaction terms between SAC-related mortality and the presence of advanced heart failure (NYHA functional class III; p=0.038), HbA1c (p=0.043) and eGFR levels (p=0.030).
Conclusions: Higher circulating aldosterone levels are related to an increased mortality risk in elderly female nursing home residents. Interventional studies are needed to assess the potential influence of MR blockade on "hard" clinical outcomes in individuals aged 70years and older.

A healthy lifestyle plays a key role for maintaining the cardiovascular health (CVH) status and prevent cardiovascular disease occurrence. In fact, a healthy lifestyle was included in the AHA Cardiovascular Health score (Life's Simple 7 [LS7]), subsequently updated to Life's Simple 8 [LS8]. Apart from the importance of controlling conventional cardiovascular risk factors, increasing evidence supports the contributory role of cardiovascular hormones.

The Fontan operation has become the primary palliative treatment for patients with a functionally univentricular heart. The population of patients with Fontan circulation is constantly growing and aging. As the number of Fontan patients surviving into adulthood increases, there is a clear need for research on how best to follow these patients and manage their complications.

Aldosterone, the primary adrenal mineralocorticoid hormone, as an integral part of the renin-angiotensin-aldosterone system (RAAS), is crucial in blood pressure regulation and maintaining sodium and potassium levels. It interacts with the mineralocorticoid receptor (MR) expressed in the kidney and promotes sodium and water reabsorption, thereby increasing blood pressure. However, MRs are additionally expressed in other cells, such as cardiomyocytes, the endothelium, neurons, or brown adipose tissue cells.

Two billion people worldwide suffer from anemia, which can lead to the onset of cardiac disorders; nevertheless, the precise mechanisms remain unclear. There are at least three distinct mechanisms by which iron deficiency (ID) contributes to the development of cardiac disorders. First, ID increases concentrations of intact fibroblast growth factor-23 (iFGF-23), which promotes left ventricular hypertrophy.

Orchidectomy and estrogenization of the male represent a procedure that is applicable in sex reassignment or in prostate cancer therapy. This approach has an influence on the hypothalamic-pituitary-adrenal axis and thus affects cardiovascular function and metabolism. We utilized orchidectomized rats to evaluate the effects of estradiol on the structure and hormonal output of the adrenal gland.
