HYPOPHOSPHATEMIA IN PATIENTS WITH ESSENTIAL ARTERIAL-HYPERTENSION

The concentration of serum inorganic phosphorus was determined in 162 patients with essential arterial hypertension (EAH) and in 71 control subjects. The serum phosphorus level was lower in patients with essential arterial hypertension than in the control subjects, and the differences were higher in the advanced stages of the disease. The lowest level of serum phosphate concentration was noted in overweight hypertensive patients, probably in relation to an enhanced insulin secretion. In control subjects the serum concentration of phosphate decreased with advancing age.
