Brief Summary:
Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular morbidity. The benefit of surgical treatment in this respect is unclear.
This study was performed to evaluate the impact of parathyroidectomy (PTX) on cardiovascular risk profile.
This study was performed to evaluate the impact of parathyroidectomy (PTX) on cardiovascular risk profile.
Detailed Description:
Patients with primary hyperparathyroidism (PHPT) have been shown to have an increased morbidity and mortality mainly due to cardiovascular disease. The precise mechanism of cardiovascular disease in PHPT is not well understood and probably multifactorial. Functional or structural alterations of vascular endothelial and smooth muscle cells may impair the vascular reactivity and lead to accelerated atherogenesis. Several cardiovascular risk factors such as obesity, hypertension, insulin resistance and hyperlipidemia are more prevalent in PHPT compared with controls.Patients with severe form of PHPT had a greater probability of metabolic syndrome (MS) and insulin resistance than patients with mild PHPT and eucalcemic subjects. Although the excess in cardiovascular mortality is significantly and independently related to serum calcium, the connection between the biochemical disturbances and the cardiovascular disorders in PHPT patients is not necessarily a cause-and-effect relationship. Indeed, the impact of surgical cure of hyperparathyroidism on cardiovascular risk factors and mortality is controversial. Some studies suggest that hypertension, dyslipidemia, and derangement of glucose metabolism improve after removal of overactive parathyroid tissue. Others have shown that cardiovascular risk markers remained unaltered after parathyroidectomy (PTX).
The aim of this study was to evaluate whether successful PTX is associated with decreased cardiovascular risk. We investigated indices of metabolic syndrome and insulin resistance as well as various cardiovascular risk factors in patients with manifest PHPT before and one year after successful PTX.
