[Echocardiographic and polycardiographic findings in multiple-transfused patients with thalassemia major]
Insights
Echocardiography can detect early cardiac changes in thalassemia major patients, even when other tests show normal function. This non-invasive method aids in monitoring treatment effectiveness.
Area of Science:
- Cardiology
- Hematology
- Pediatrics
Background:
- Thalassemia major patients often experience cardiac complications due to anemia and iron overload.
- Chelation therapy is crucial for managing iron overload in these patients.
Purpose of the Study:
- To evaluate cardiac function in thalassemia major patients undergoing chelation therapy.
- To assess the utility of echocardiography and polycardiography in detecting cardiac alterations.
Main Methods:
- Echocardiographic and polycardiographic measurements were performed on 11 thalassemia major patients (ages 2-24).
- Patients received subcutaneous Deferoxamine and Vitamin C therapy.
- Cardiac parameters including left ventricular dimensions, aorta, and left atrium were assessed.
Main Results:
- Echocardiography revealed normal cardiac values in 7 patients.
- Four patients showed left ventricular enlargement, with progressive involvement of the aorta and left atrium in three.
- Polycardiography indicated normal cardiac efficiency in most patients, with one exception.
Conclusions:
- Echocardiography is a valuable, non-invasive tool for early detection of cardiac alterations in thalassemia major.
- Findings suggest anemia and iron overload contribute to cardiac changes.
- Echocardiography facilitates long-term monitoring of cardiac function and chelation therapy efficacy.
Abstract:
Echocardiographic and policardiographic measurements were carried out in 11 thalassemic major patients between 2 and 24 years of age, kept at on average Hb level of 9,77 gr.% (+/- 1,13) and who underwent chelation therapy with Deferoxamine subcutaneous and Vit. C. The echocardiographic examination gave normal values in 7 patients. In 4 patients underwent enlargement of the left ventricle: only in the telediastolic diameter in one case, with progressive involvement of the aorta and the left atrium in another 3 cases. Such alterations, as have already been recorded by various researchers, are probably the result of a condition due to the anemia state of the younger patients, whereas in older and polytransfused patients may be attributed to iron overload. No parameters surveyed by the polycardiographic examination indicated significant alterations in cardiac efficiency, except of one patient. The importance of echocardiography should be stressed; it is a simple, non invasive way of recording early cardiac alterations in thalassemic major patients and enables long-term monitoring of cardiac function in the assessment of the effectiveness of the chelation therapy.
