Cardiovascular Morbidity in Patients Undergoing Successful Surgery for Primary Hyperparathyroidism

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Surgical Outcomes

Background:

• Primary hyperparathyroidism (pHPT) is linked to cardiovascular disease.
• Previous studies suggest parathyroidectomy (PTX) may reduce cardiovascular events.
• Contemporary PTX outcomes in milder pHPT require further investigation.

Purpose of the Study:

• To assess cardiovascular event incidence after PTX in a nationwide cohort.
• To evaluate cardiovascular disease manifestations in pHPT patients before and after PTX.
• To identify predictors of cardiovascular events in pHPT.

Main Methods:

• A nationwide cohort of 5009 PTX patients was identified.
• Patients were matched with 14,983 population controls.
• Cardiovascular event rates (myocardial infarction, stroke, TIA, heart failure, valve stenosis, aortic aneurysm) were compared pre- and post-PTX using linked national registries.

Main Results:

• Heart failure and mitral valve stenosis incidence decreased post-PTX.
• Transient ischemic attack (TIA) and aortic aneurysm (AA) incidence remained elevated post-PTX.
• Acute myocardial infarction and stroke rates were not significantly altered by PTX.

Conclusions:

• PTX normalizes heart failure and mitral valve stenosis in pHPT patients.
• TIA and AA incidence persist post-PTX, indicating ongoing cardiovascular risk.
• Long-term cardiovascular monitoring is crucial for pHPT patients after PTX.
