In recent years, the even more subtle normocalcemic (NC) variant is being increasingly recognized. We sought to compare the prevalence of CV risk factors in patients with NC- and hypercalcemic (HC)-PHPT, and to examine whether they differ on a battery of non-invasive vascular parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design\/subjects\/methods<\/jats:title><jats:p>A retrospective study of two cohorts of patients with PHPT in a referral center: 32 subjects with NC-PHPT and 81 subjects with HC-PHPT, compared for the presence of clinical and biochemical risk factors, and CV morbidity. Non-invasive parameters of arterial stiffness (augmentation index; pulse wave velocity; and vascular compliance indices, C1 and C2) were extracted from the data of gender- and age-matched subsets of these patients, and were related to those of a group of matched control subjects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Despite a similar prevalence of hypertension (\u223c62%), hyperlipidemia (\u223c30%), and impaired glucose metabolism in both PHPT groups, CV or cerebrovascular disease was more common in the HC-PHPT group (24.7 vs 3.1%,<jats:italic>P<\/jats:italic>=0.007). Arterial stiffness parameters did not differ in the three groups, and were unrelated to serum calcium or parathyroid hormone concentration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>NC-PHPT and HC-PHPT subjects exhibit similar high rates of traditional CV risk factors, and have comparable indices of arterial stiffness. The lower clinical CV morbidity observed with NC-PHPT remains unexplained, and requires confirmation.
