CONTEXT: Current evidence of cardiovascular (CV) risk in primary hyperparathyroidism (PHPT) is still inconsistent.
OBJECTIVE: To prospectively investigate changes of early atherosclerosis in patients with PHPT undergoing parathyroidectomy (PTx) or conservative management, according to consensus criteria.
METHODS: Biochemical parameters of PHPT, CV risk factors (systolic and diastolic blood pressure, cholesterol [total, high-density, and low-density], triglyceride, HbA1c, HOMA-IR), and carotid intima-media thickness (IMT) and plaque were assessed in 52 consecutive postmenopausal PHPT patients both at baseline and ≥ 24 months after surgery (PTx, n = 22) or conservative management (non-PTx, n = 30).
RESULTS: At baseline, PTx and non-PTx showed comparable age, BMI, renal function, and 25(OH)D levels, and did not differ for CV risk factors, IMT and plaques, or for prevalence of smoking, diabetes mellitus, or antihypertensive or statin therapy, while all parameters characterizing PHPT differed. Follow-up duration in PTx was longer than in non-PTx (P = .004). Parameters characterizing PHPT significantly improved ≥ 24 months after surgery, whereas in non-PTx serum phosphate slightly decreased and parathyroid hormone increased. Systolic and diastolic blood pressure increased at follow-up in both groups, while other CV risk factors did not significantly vary. In PTx, IMT did not significantly vary after surgery (0.85 ± 0.14 to 0.89 ± 0.22 mm, P = .366), whereas it significantly increased in non-PTx (0.80 ± 0.18 to 0.93 ± 0.23 mm, P = .008), even adjusting for blood pressure. Plaque prevalence and incidence did not significantly differ in the 2 groups.
CONCLUSION: Our results suggest that in postmenopausal patients with PHPT, subclinical atherosclerosis could be halted by PTx, whereas it worsens over time in nonoperated patients with milder disease.
