Abstract

We sought to compare the incidence of adverse cardiovascular events in older adults with primary hyperparathyroidism (PHPT) treated with parathyroidectomy versus non-operative management.PHPT is a common endocrine disorder that is associated with increased cardiovascular mortality, but it is not known whether parathyroidectomy reduces the incidence of adverse cardiovascular events.We conducted a population-based, longitudinal cohort study of Medicare beneficiaries diagnosed with PHPT (2006-2017). Multivariable, inverse probability weighted Cox proportional hazards regression was used to determine the associations of parathyroidectomy with major adverse cardiovascular events (MACE), cardiovascular disease-related hospitalization, and cardiovascular hospitalization-associated mortality.We identified 210,206 beneficiaries diagnosed with PHPT from 2006-2017. Among 63,136 (30.0%) treated with parathyroidectomy and 147,070 (70.0%) managed non-operatively within one year of diagnosis, the unadjusted incidence of MACE was 10.0% (mean follow-up 59.1 [SD 35.6] months) and 11.5% (mean follow-up 54.1 [SD 34.0] months), respectively. In multivariable analysis, parathyroidectomy was associated with a lower incidence of MACE (HR 0.92 [95%CI 0.90-0.94]), cardiovascular disease-related hospitalization (HR 0.89 [95%CI 0.87-0.91]), and cardiovascular hospitalization-associated mortality (HR 0.76 [95%CI 0.71-0.81]) compared to non-operative management. At 10 years, parathyroidectomy was associated with adjusted absolute risk reduction for MACE of 1.7% (95%CI 1.3%-2.1%), for cardiovascular disease-related hospitalization of 2.5% (95%CI 2.1%-2.9%), and for cardiovascular hospitalization-associated mortality of 1.4% (95%CI 1.2%-1.6%).In this large, population-based cohort study, parathyroidectomy was associated with a lower long-term incidence of adverse cardiovascular outcomes when compared with non-operative management for older adults with PHPT, which is relevant to surgical decision-making for patients with a long life expectancy.
