Assessment of left ventricular diastolic function and the Tei index by tissue Doppler imaging in patients with primary hyperparathyroidism.

Background: The aim of this study was to assess left ventricular (LV) systolic and diastolic function and myocardial performance (the Tei index) by tissue Doppler imaging (TDI) in patients with primary hyperparathyroidism (PHPT).

Methods: We prospectively evaluated 21 patients with PHPT [nine women, 12 men; aged 50 +/- 11 years, serum calcium 2.9 +/- 0.
