Summary
Acromegaly patients often have subclinical cardiac issues. Echocardiography is key for detecting and monitoring these heart abnormalities, even when growth hormone (GH) levels decrease.
Area of Science:
- Cardiology
- Endocrinology
- Medical Diagnostics
Background:
- Acromegaly, caused by excess growth hormone (GH), is linked to cardiovascular complications like hypertension and diabetes.
- Cardiac decompensation and arrhythmias in acromegaly may indicate a specific GH-induced cardiomyopathy, independent of other risk factors.
Purpose of the Study:
- To assess the presence and progression of subclinical cardiac alterations in acromegaly patients.
- To evaluate the effectiveness of echocardiography in diagnosing and monitoring cardiac involvement in acromegaly.
Main Methods:
- Echocardiography was used to examine cardiac structure and function in 8 acromegaly patients.
- Patients were reassessed 2-4 years after treatment to observe changes in cardiac parameters and GH levels.
Main Results:
- Initial echocardiography revealed subclinical cardiac abnormalities, including left ventricular hypertrophy, in most patients.
- Despite some reduction in GH and IGF-1 (Insulin-like Growth Factor 1) levels post-treatment, cardiac function showed deterioration in several cases.
- Echocardiography demonstrated significant changes in diastolic diameter and ejection fraction over time.
Conclusions:
- Acromegaly patients frequently exhibit subclinical cardiac abnormalities.
- Echocardiography is a highly sensitive non-invasive tool for diagnosing and following cardiac involvement in acromegaly.
- The progression of cardiac alterations is only partially influenced by reduced GH and IGF-1 levels.
