  • Cardiac Structure and Function Before and After Parathyroidectomy in Patients With Asymptomatic Primary Hyperparathyroidism

    • Background: Primary hyperparathyroidism (PHPT) is associated with cardiac disease and increased risk of all-cause and cardiovascular mortality. We investigated cardiac structural and functional parameters before and after successful parathyroidectomy in asymptomatic PHPT patients. Methods and Results: Forty-nine PHPT patients (age: 62.9 +/- 11 years, 5 men) and 48 healthy control subjects, matched for age, sex and smoking status were enrolled in the study. PHPT patients were examined preoperatively and 6 and 12 months postoperatively. Structural and functional cardiac parameters were assessed by transthoracic echocardiography. One year after parathyroidectomy left ventricular (LV) mass, left atrial size, LV enddiastolic and endsystolic diameters, LV posterior wall and interventricular septum diameter, and right ventricular enddiastolic diameter were all increased in PHPT patients, although not significantly. As an indication of worsened LV diastolic function, the heart rate adjusted Doppler-derived deceleration time of the transmittal E-wave increased among PHPT patients (276 +/- 82-303 +/- 54 milliseconds, P = 0.004). There was also deterioration of LV ejection fraction (from 62.7 +/- 7 to 59.9 +/- 7.8%, P = 0.868) and mean atrioventricular plane displacement (from 13.2 +/- 2 to 12.6 +/- 2 mm, P = 0.029). Conclusion: There were no significant differences in heart function between hyperparathyroid and control subjects, and 6 months after parathyroidectomy, there was no change in heart function in hyperparathyroid subjects.

  • Postexercise Cardiac Performance Among Patients With Mild Primary Hyperparathyroidism
  • 2009
  • Ingår i: The Endocrinologist. - 1539-9192. ; 19:6, s. 263-266
  • Tidskriftsartikel (refereegranskat)abstract
    • Primary hyperparathyroidism (pHPT) is associated with cardiac disease. This prospective study was designed to investigate changes in cardiac function before and after parathyroidectomy. Resting and post exercise cardiac function was compared with matched control subjects. Fifty patients (mean age 62.9 +/- 11 years, 45 women) and 50 healthy control subjects, matched for age and sex were studied. Resting and postmaximum exercise echocardiography/Doppler examination were performed at baseline and 6 months after parathyroidectomy. pHPT patients were tested at baseline and 6 months postoperatively. Control subjects were tested only at baseline. Patients were divided into 4 subgroups based on median preoperative levels of PTH and calcium (Ca): high (up arrow) PTI4/ up arrow Ca, up arrow PTH/low (down arrow) Ca, up arrow Ca/ down arrow PTH, and down arrow PTH/ down arrow Ca. No significant difference between pHPT patients and control subjects regarding post exercise systolic function were detected, There was a tendency of lowed E/A among pHPT patients which was significant in subgroup down arrow PTH/ down arrow Ca (1.07 +/- 0.3). Subgroup up arrow PTH/ up arrow Ca showed a lower S/D compared with control subjects at baseline (1.28 +/- 0.3 vs. 1.48 +/- 0.3, P = 0.029). No significant changes regarding post exercise echocardiographic parameters reflecting cardiac function were detected 6 months after parathyriodectomy. Patients with asymptomatic pHPT showed a tendency of elevated filling pressures and signs of impaired diastolic function during exercise.

  • Relationship Between Mild Primary Hyperparathyroidism and Left Ventricular Structure and Diastolic Performance
  • 2009
  • Ingår i: The Endocrinologist. - 1539-9192. ; 19:4, s. 187-191
  • Forskningsöversikt (refereegranskat)abstract
    • Aim: This study aims to investigate cardiac structure and function in patients with asymptomatic primary hyperparathyroidism (pHPT) and if there is any relation to severity regarding serum levels of calcium (Ca) and parathyroid hormone. Methods and Results: We consecutively included 50 patients (mean age 62.9 +/- 11 years, 45 women) with clinically diagnosed pHPT. We prospectively recruited 50 healthy control subjects, matched for age and sex. Standard transthoracic echocardiographic examination was performed using the 4 standard views and structural parameters as well as left ventricular (LV) systolic and diastolic function was determined. Mean LV ejection fraction and atrioventricular plane displacement were on average normal and did not differ between patients and controls. However, pHPT patients had significantly greater LV mass (148 +/- 37 vs. 127 +/- 29 g, P = 0.002), LV end diastolic area (81 +/- 20 vs. 68 +/- 18 cm(2), p = 0.003), LV posterior wall diameter (8.9 +/- 1 vs. 8.1 +/- 1 min, P = 0.006), and LA size (21 +/- 3 vs. 19 +/- 2 mm, P < 0.001). A moderate to severe LV diastolic filling impairment was present in substantially more pHPT patients, compared with control subjects (36% vs. 4%, P < 0:001). Conclusion: Patients with asymptomatic pHPT showed LV structural changes and impaired LV diastolic function.

  • Effect of successful parathyroidectomy on 24-hour ambulatory blood pressure in patients with primary hyperparathyroidism.
  • 2010
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273. ; 142, s. 15-21
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The pathogenesis of hypertension in patients with primary hyperparathyroidism (PHPT) is unclear, and the prevailing opinion is that parathyroidectomy does not affect the blood pressure (BP). Most previous studies have been based on BP measurements at rest in a clinical setting. The aim of this study was to get additional information by 24-hour ambulatory measurements. DESIGN AND PATIENTS: Forty-nine consecutive patients with PHPT (age 63+/-12 years, 44 women) were examined before and 6 months after curative parathyroid surgery. MEASUREMENTS: Serum concentrations of calcium and PTH, and 24-hour ambulatory mean, minimum, and maximum systolic (S) and diastolic BP, and mean arterial BP. RESULTS: On average, the patients showed no BP change after parathyroidectomy. However, those with a history of hypertension (n=20) showed generally increased BP values after parathyroidectomy, with significantly increased minimum and average SBP (P=0.02 and P=0.04, respectively), whereas patients without a history of hypertension (n=29) showed unchanged or slightly reduced BP values after parathyroidectomy, with significantly decreased maximum SBP (P=0.04). Serum concentrations of PTH and calcium were not significantly related to any of the BP variables measured. CONCLUSIONS: The novel finding that patients with both PHPT and hypertension may show increased BP after parathyroidectomy warrants intensified BP control postoperatively in these patients, and motivates early treatment of PHPT in order to prevent the development of complicating hypertension.
