10-year cardiovascular disease risk and its contributing factors in primary hyperparathyroidism.

objectiveSurgery indications for primary hyperparathyroidism (PHPT) mostly concern kidney and bone outcome, but not cardiovascular disease (CVD). Age less than 50 and eGFR less than 60 ml/min/1.73m2 are two surgery indications. This study aims to evaluate factors influencing the 10-year CVD risk in PHPT patients.

method159 PHPT patients diagnosed between January 2024 - March 2025 were enrolled. The relationships between biochemical and echocardiographic parameters with 10-year CVD risk score calculated by PREVENT™ were analyzed. Univariate, multivariate, logistic regression and receive operation curve (ROC) analysis were employed.

results10-year CVD risk score was positively corelated with age (R2adjusted = 0.604, β = 0.541), systolic blood pressure (R2adjusted =0.149, β = 0.185), eGFR (R2adjusted =0.452, β=-0.252), triglyceride (R2adjusted =0.134, β = 3.629) with P < 0.001.These parameters together with smoking, diabetes and left ventricular end-diastolic diameter were responsible for 10-year CVD risk (R2adjusted =0.849, P < 0.001). Age and eGFR were the two strongest factors to discriminate moderate-to-high risk and low risk, with area under the curve 0.935 (95%CI 0.896–0.974) and 0.827 (95%CI 0.763–0.891), respectively. The optimal cutoffs to identify moderate-to-high CVD risk were age at 56.5 and eGFR at 98.5 ml/min/1.73m2, PHPT patients older or lower than these two thresholds had significantly higher CVD risk than their counterparts (P < 0.001).

conclusionAge and eGFR were significant contributors to CVD risk in PHPT. Patients should be closely monitored and managed for dysregulated gluco-lipid metabolism. Less restrictive surgery indication for PHPT, such as age < 56, irrespective of renal function might be considered.
