Scientists find an important but ignored cause of high blood pressure

In a recent study published in the Annals of Internal Medicine, researchers showed that the hormone aldosterone is actually a common and unrecognized contributor to high blood pressure.

It is much more common than previously recognized.

The study is from Brigham and Women’s Hospital and elsewhere. One author is Jenifer M. Brown, M.D.

High blood pressure affects more than 1.5 billion people worldwide and is arguably the leading preventable cause of heart disease and stroke.

Primary aldosteronism is a condition where the adrenal glands produce too much of the hormone aldosterone, which causes high blood pressure and heart disease.

The health condition has traditionally been considered to be an uncommon cause of high blood pressure.

In the study, the team examined patients with normal blood pressure, stage 1 high blood pressure, stage 2 high blood pressure, and resistant high blood pressure to determine the prevalence of excess aldosterone production and primary aldosteronism.

They found that there was a continuum of excess aldosterone production that paralleled the severity of blood pressure.

Importantly, most of this excess aldosterone production would have not been recognized by currently recommended diagnostic approaches.

The finding supports the need to redefine primary aldosteronism from a rare disease to, instead, a common syndrome that manifests across a broad severity spectrum and may be a primary cause of high blood pressure.

Since generic medications that block the deleterious effects of aldosterone already exist and are easily available, these findings suggest that using these drugs more frequently to treat high blood pressure may be an effective way to lower the risk of heart disease.
