Insights
Resecting pituitary tumors significantly improves cardiac function in patients with pituitary adenoma and dilated cardiomyopathy. Improved cardiac function, including ejection fraction, correlates with reduced growth hormone levels post-surgery.
Area of Science:
- Cardiology
- Endocrinology
- Oncology
Context:
- Pituitary adenoma can lead to dilated cardiomyopathy.
- Growth hormone (GH) plays a role in cardiac function.
- Surgical intervention is a primary treatment for pituitary tumors.
Purpose:
- To evaluate cardiac function changes after pituitary tumor resection in patients with co-existing dilated cardiomyopathy.
- To assess the correlation between GH levels and cardiac function improvements.
Summary:
- Retrospective analysis of 14 patients with pituitary adenoma and dilated cardiomyopathy.
- Echocardiography and GH levels were measured before and after pituitary tumor resection.
- Significant improvements in left ventricular end-diastolic diameter, septal thickness, posterior wall thickness, and ejection fraction were observed post-surgery.
Impact:
- Pituitary tumor resection can reverse cardiac dysfunction in affected patients.
- The degree of cardiac improvement is linked to the reduction in GH levels.
- This study highlights the importance of managing pituitary adenomas to improve cardiac outcomes.
Objective:
To evaluate the cardiac function changing before and after resection of pituitary tumor in patients with pituitary adenoma complicated with dilated cardiomyopathy with retrospective analysis method.
Methods:
The clinical data of 14 cases of patients with pituitary adenoma complicated with dilated cardiomyopathy, treated with resection of pituitary tumor, in PLA General Hospital, from 2005 to 2011, were collected and analyzed. Comparative analysis of cardiac function were made in these patients before and after the surgery, also with the postoperative recovery status, using echocardiography and other noninvasive detection means to detect the growth hormone (GH), left ventricular end-diastolic diameter (LVEDD), septal thickness (ST), left ventricular posterior wall thickness (LVPWT), left ventricular ejection fraction (LVEF) values.
Results:
After the resection of pituitary tumor, the LVEDD, ST, LVPWT, LVEF levels were all significantly better than that before the surgery. Before the surgery the GH, ST, LVPWT, LVEF levels were 93.89 µg/L, 11.13 mm, 43.92% and 10.53 mm, while those after the surgery were 5.16 µg/L, 10.64 mm, 49.28% and 8.87 mm. The difference of the GH level before and after the surgery was correlated with the difference of ST, LVEDD and LVEF in a linear manner.
Conclusions:
Resection of pituitary tumor can significantly improve the cardiac function in patients with pituitary adenoma complicated with dilated cardiomyopathy, and the cardiac function improving level is correlated with the difference of GH levels before and after the surgery.
