Cardiovascular risk factors in primary hyperparathyroidism.

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Metabolic Disorders

Background:

• Severe primary hyperparathyroidism (PHP) is linked to cardiovascular issues.
• The cardiovascular impact of mild PHP remains unclear.
• This study investigates cardiovascular risk factors in mild and severe PHP.

Purpose of the Study:

• To assess the correlation between mild and severe primary hyperparathyroidism (PHP) and emergent cardiovascular risk factors.
• To determine if serum calcium predicts metabolic syndrome and insulin resistance in PHP patients.

Main Methods:

• Cross-sectional study of 139 PHP patients (72 severe, 67 mild) and 111 controls.
• Measured fasting blood levels of calcium, PTH, lipids, glucose, insulin, and inflammatory markers.
• Evaluated BMI, waist circumference, blood pressure, insulin resistance (IR), and metabolic syndrome (MS).

Main Results:

• Severe PHP patients exhibited higher rates of MS (37.5%) and IR (38.9%) compared to mild PHP (34.3%, 23.9%) and controls (14.4%, 14.4%).
• Severe PHP was significantly associated with increased likelihood of MS (OR 3.5) and IR (OR 3.7).
• Serum calcium levels significantly predicted the presence of MS (OR 1.875) and IR (OR 2.043).

Conclusions:

• Patients with severe primary hyperparathyroidism (PHP) face a greater probability of developing metabolic syndrome and insulin resistance.
• Serum calcium is a significant predictor of these cardiovascular risk factors in PHP.
• These findings highlight the importance of monitoring cardiovascular health in PHP patients.
