From volume\u2013time curves of cine MRI, the time for deceleration (Tdec) was determined to assess the left ventricle (LV) chamber stiffness. Based on phase\u2010sensitive reconstructed LGE images, a fibrosis index called enhancement value (EV) was computed as the signal intensity change in the myocardium over blood before and after contrast. Both Tdec and EV were compared between patients and controls. The association between Tdec and EV was investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Patients showed a significantly higher EV (0.43 \u00b1 0.05 vs. 0.36 \u00b1 0.07; <jats:italic>P<\/jats:italic> = 0.002) and a significantly shorter Tdec (11.5 \u00b1 3.5 %RR vs. 15.3 \u00b1 2.4 %RR; <jats:italic>P<\/jats:italic> = 0.004) than controls.
