Fig. 8From: Left ventricular mechanical dysfunction in diet-induced obese mice is exacerbated during inotropic stress: a cine DENSE cardiovascular magnetic resonance studyLeft ventricular circumferential systolic strain rates at baseline (top) and stress (bottom) at the indicated times with respect to diet initiation. No statistical differences between groups were observed at baseline. Strain rates increased for both groups with stress; however, the obese group did not maintain this contractile reserve over time and, beginning at week 22, they had significantly lower values than controlsBack to article page
