Diastolic Doppler changes in beta-thalassemia may reflect preload or iron overload; leaves open prospective validation for risk stratification.
What are the left ventricular diastolic Doppler characteristics in patients with beta-thalassemia major compared to normal individuals?
Doppler diastolic indexes in beta-thalassemia major patients with normal LV systolic function resemble conditions with increased preload, while severe iron loading leads to restrictive LV filling abnormalities.
Kremastinos et al. (1993) studied this question.
