Abstract

Summary

Pulmonary hypertension is common in adults with thalassaemia and other haemolytic anaemias. It was hypothesised that regular transfusions in thalassaemia major should both decrease the chronic haemolytic rate and be protective from pulmonary hypertension (PHT). To reduce the contribution of existing cardiac disease to PHT, the subjects were limited to patients with normal left ventricular shortening fractions. Associations with multiple laboratory markers of haemolysis, serum ferritin levels, chest X-rays findings and splenectomy status were also considered. We found no biochemical, transfusional, or clinical (except gender) differences in transfused thalassaemia patients with or without pulmonary hyper tension.
