title: Clinical aspects of parathyroid hypertensive factor.
abstract: To determine the clinical significance of parathyroid hypertensive factor (PHF), physiological studies previously performed in animal models of hypertension were parallelled by human studies. These studies revealed that PHF-like activity is present in human hypertension, where it correlates with the salt-sensitive, low-renin state. As in spontaneously hypertensive rats, both supplemental calcium and calcium-channel blockers appear to be useful in the treatment of PHF-related hypertension. In primary hyperparathyroid patients, PHF presence is linked with the presence of hypertension. Postparathyroidectomy blood pressure falls in parallel with PHF levels. These preliminary human studies suggest that PHF may be a useful marker in the treatment of hypertension.
