5 cm and the intraventricular septum of the left ventricle was 0.
The interventricular septal thickness was assessed as an independent variable in both the groups, but was not found to be statistically significant to reject the null hypothesis, suggesting that the intraventricular septum (IVS) is significantly thickened in both the groups.
But it's noteworthy that investigators at the University of Cagliari (Italy) have demonstrated that these abnormalities--including left ventricular posterior wall thickening, increased intraventricular septum thickness, increased left ventricular end-diastolic dimension, and an associated diminished exercise tolerance--are reversible by titrating the levothyroxine dose down to the minimum still capable of inducing TSH suppression (J.
