Clinical correlates in parathyroid hypertension.

There is a known association between hypertension and hyperparathyroidism but the mechanism remains unclear. A total of 115 patients with hyperparathyrodism were examined in a retrospective study, and 54.8% were hypertensive. Serum urea and creatinine levels were higher in the hypertensive patients compared with the normotensive patients. Parathyroidectomy had little effect on blood pressure, suggesting that hypertension alone is not an indication for surgery in these patients.
