4. Results
27 of 51 participants were female (52.9%) and mean ages of two study population were similar (27.66 + 1.62 vs 27.13 + 1.01 for patients with T2* ≤20ms and >20ms, respectively). Baseline characterisitcs of study population shown in Table 1. We found that LVEF3D (53.25 +2.33 vs 58.81 +1.02), SDI12 (6.53 +0.56 vs 2.85 +0.48), SDI16 (7.65 +0.75 vs 3.26 +0.49), FMD (6.08% + 0.34 vs 14.46% + 1.12), aortic strain (7.79% + 2.19 vs 12.76% + 4.19); and also serum ferritin values were significantly different between groups with T2* ≤20ms and >20ms, respectively (Table 2). For all parameters found significantly different between two study groups, there were also significant positive or negative correlations with T2* value (Figure 3). Echocardiographic measurements were performed by two experienced operators and repeated by same operator at another time; and perfect inter-observer (k=0.89) and intra-observer (k = 0.92) agreements were achieved.
