Insights
Patients with acromegaly experience significant electrical heart disturbances, including prolonged QT intervals and arrhythmias. Early cardiac monitoring by a cardiologist is recommended for these patients.
Area of Science:
- Cardiology
- Endocrinology
Background:
- Hormonal imbalances, particularly in the thyroid, parathyroid, adrenal, and gonadal glands, are well-researched regarding circulatory effects.
- The relationship between growth hormone and the cardiovascular system requires further investigation.
Purpose of the Study:
- To describe cardiovascular complications in acromegaly detectable by standard electrocardiogram (ECG) and 24-hour Holter monitoring.
Main Methods:
- Compared 28 acromegaly patients (15 with hypertension) with 20 hypertensive patients and 20 healthy controls.
- All subjects underwent physical examination, resting ECG, and 24-hour Holter monitoring.
- Evaluated heart rate, arrhythmias, QRS, QT, QTc intervals, and atrial/ventricular hypertrophy.
Main Results:
- Acromegaly patients exhibited significant electrical cardiac disturbances.
- Substantial QT and QTc interval prolongation and QRS complex prolongation were observed.
- Supraventricular and ventricular arrhythmias were more frequent in acromegaly patients.
Conclusions:
- Acromegaly is associated with significant, potentially life-threatening electrical heart function disturbances.
- Acromegaly patients warrant early and regular cardiological monitoring.
Unlabelled:
Aberrations in circulation related to improper thyroid, parathyroid, adrenal and gonadal function were well researched and recognized. Our knowledge of relation between growth hormone and cardiovascular system is somewhat limited.
Aim Of The Study:
Our attention was describe occurring in acromegaly complications of cardiovascular function detectable by standard 12-lead ECG and 24-hour Hotter monitoring.
Material And Methods:
Our research compared 28 patients (15 with hypertension among them) with acromegaly with mean 10-years duration of disease, 20 patients with hypertension and 20 normal subjects. All subjects underwent physical examination followed by standard resting ecg and 24-hour Holter monitoring. Several different ECG parameters were compared: heart reate, arrhythmia (in Holter), times of QRS, QT and QTc intervals and features of atrial and ventricle hypertrophy.
Results:
Result of this comparison indicates presence of substantial electric cardiac disturbances in acromegaly patients. Patients with acromegaly have substantial QT and QTc prolongation. ECG analysis showed QRS complex prolongation in this group. Much often they had supraventricular and ventricular arrhythmias. Those are complex aberrances which may have important implications for patient's well-being.
Conclusion:
In acromegaly patients significant electrical heart function disturbances were shown. These could be threatening for their life. This group should be early monitored by cardiologist.
