Insights

Primary hyperparathyroidism (PHP) can impair cardiac systolic function, even in asymptomatic patients. Surgical treatment improved global longitudinal strain (GLS) detected by strain echocardiography, suggesting its value in managing PHP cardiac complications.

Area of Science:

  • Cardiology
  • Endocrinology
  • Medical Imaging

Background:

  • Primary hyperparathyroidism (PHP) is a common cause of hypercalcemia with known cardiac complications like arrhythmia and hypertrophy.
  • Existing data on cardiac systolic function and surgical treatment effects in PHP are limited.
  • This study investigates the impact of surgery on left ventricular systolic function in PHP patients using strain echocardiography.

Purpose of the Study:

  • To evaluate postoperative changes in left ventricular systolic function in patients with primary hyperparathyroidism (PHP).
  • To compare strain echocardiography (STE) parameters, specifically global longitudinal strain (GLS) and global circumferential strain (GCS), before and after surgical intervention.
  • To determine if STE can detect subclinical myocardial dysfunction in PHP patients that may not be apparent with conventional echocardiography.

Main Methods:

  • Prospective study of 29 patients with primary hyperparathyroidism (PHP).
  • Echocardiographic assessments, including conventional and strain echocardiography (STE), were performed preoperatively and 6 months post-surgery.
  • Preoperative and postoperative STE parameters (GLS, GCS) were compared; patients with specific exclusions were not included.

Main Results:

  • No significant change was observed in ejection fraction post-surgery.
  • Global longitudinal strain (GLS) significantly improved from 18.53 ± 3.06 preoperatively to 20.25 ± 3.89 at 6 months post-surgery (P = .004).
  • Other echocardiographic parameters showed no significant changes.

Conclusions:

  • Global longitudinal strain (GLS) values deteriorated preoperatively and improved post-surgery, indicating subclinical systolic dysfunction in PHP.
  • Strain echocardiography (STE) may detect early myocardial dysfunction in asymptomatic PHP patients, potentially offering a new treatment indication.
  • Further extensive studies with longer follow-up are needed due to limited current literature.
