The
aim was to investigate the effect of high fat diet on myocardial triglyceride
and function in preclinical model. Male C57/Bl6 mice were maintained on a
high (21%) fat (HF n=6) or a normal (3%) fat diet (C, n=5). Using MRI left ventricular
ejection fraction (LVEF) was measured,
while localized 1H MRS was used to estimate lipids content in the
interventricular septum in animals. Lipid content was significantly increased
in HF group, while trend was observed in LVEF decrease in HF group. These
preliminary results suggest that high fat diet may have implications on
myocardial lipid content and cardiac function.
