Aldosterone sensitivity: an opportunity for investigation into the pathogenesis of hypertension.
Aldosterone sensitivity: an opportunity for investigation into the pathogenesis of hypertension. American journal of physiology. Renal physiology Gray, Z. n., Tu, W. n., Chertow, G. M., Bhalla, V. n. 2021Abstract
Aldosterone sensitivity is defined as an outcome variable for a given circulating level of aldosterone. In basic and translational studies, this has been measured in differential tissue responses, e.g. lower urine sodium and higher urine potassium, as an index of renal response; and in clinical studies has been measured in differential blood pressure. This concept of aldosterone sensitivity disrupts the conventional wisdom of the renin-angiotensin-aldosterone system and has the potential to uncover novel mechanisms of hypertension. We review basic and translational science studies that uncovered differential renal responses to aldosterone and connect this earlier work to more recent observational and randomized trials that have demonstrated differential blood pressure for a given level of aldosterone in healthy and hypertensive subjects. Black race and age are associated with higher aldosterone sensitivity and blood pressure. We also discuss gaps in the field and how future basic and clinical studies can inform mechanisms of differential sensitivity.
