Abstract
Among the factors associated with thalassemic heart disease, endocrine disturbance is also a contributing factor. We present a retrospective, cross sectional study, which aims to establish the prevalence of cardiac complications in thalassaemia major (TM) patients with endocrine complications and to evaluate the influence of endocrine disease on cardiac complications. Endocrinological and cardiological parameters were considered on 957 TM patients who are enrolled in the Myocardial Iron Overload in Thalassemia (MIOT) network in 68 sites in Italy. Patients with pubertal hypogonadism (163 males and 175 females), hypothyroidism (192), diabetes mellitus (87) and hypoparathyroidism (61), were compared according to cardiac complications: global heart T2*, cardiac dysfunction, heart failure, arrythmias, pulmonary hypertension and myocardial fibrosis. Control groups were made up according to the age range of patients with the corresponding endocrinopathy. The prevalence of cardiac dysfunction, arrhythmias and heart failure was significantly increased in patients with endocrinopathies. Cardiac complications tended to increase according to the number of endocrinologies affecting the patient. Aim of our retrospective and cross sectional study was to establish the prevalence of cardiac complications in thalassemia major (TM) patients with endocrine diseases and to evaluate the influence of endocrine diseases on cardiac complications.
