Correlations between global circumferential strain (GCS), global radial strain (GRS) and torsion with other global parameters in 116 patients. Strain and torsion derived from DENSE, FT and tagging with Pearson correlation with left ventricular ejection fraction (EF), systolic blood pressure (SBP), left ventricle end diastolic volume (LVEDV), left ventricle end systolic volume (LVESV), late gadolinium enhancement (LGE) and left ventricle mass index (LVMI). **Correlation is significant at the 0.01 level and *at the 0.05 level
