There was a statistically significant difference in the mean age of diagnosis, the frequency of blood transfusions ≥5 times / year in the group of thalassemia patients with reduced left ventricular ejection fraction with the control group (p<0.05); Mean EF (53.16±1.12), mean FS (31.16±2.46) evaluating left ventricular systolic function of the disease group were lower than the control group, with p<0.05; There was a statistically significant difference between the disease group with blood ferritin ≥ 2500 ng / ml of the patient group and the control group, with p< 0.05.
