Findings from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, have revealed that adding the medication known as spironolactone (Aldactone) to existing therapy did not significantly reduce the composite time to either death from cardiovascular causes, surviving a cardiac arrest, or hospitalization to manage heart failure in patients with heart failure and a preserved ejection fraction in a study funded by the National Heart, Lung and Blood Institute, National Institutes of Health.

Pregnenolone is produced from cholesterol and depending upon the environmental needs it will form into various amounts of progesterone, cortisol, aldosterone and DHEA.

Production of aldosterone by the adrenals depends on how much cortisol - stimulating hormone (ACTH) is being sent from the brain.

The brain takes its signals from the amount of circulating cortisol — not circulating aldosterone — so high cortisol tends to lower the brain's ACTH production, which in turn decreases aldosterone secretion, leading to lower blood pressure.

Another consequence of low aldosterone is electrolyte imbalance and cell dehydration, which both have negative effects on almost all physiological reactions in the body: aside from salt cravings, low blood pressure and light - headedness, patients with adrenal fatigue often experience an irregular heart beat, lethargy, muscle weakness, and increased thirst.

Like cortisol, aldosterone follows a diurnal pattern of secretion, peaking at 8 a.m., and at it's lowest from 12 - 4 a.m.
