Transformation of myocardial energy metabolism pattern during myocardial remodeling caused by volume overload

Objective To elucidate the transformation of energy metabolism patterns in the process of myocardial remodeling induced by volumeoverload and to explore a novel intervention target for the prevention,delay or even reversal of structural heart dysfunction.Methods Thirty C57/BL6 mice,20-30 g,half male and half female,were randomly divided into model group(n=15)and sham operation group(n=15).Each group was divided into subacute phase(2 weeks after surgery,n=5),cardiac functional compensation phase(5 weeks after surgery,n=5)and decompensation phase(15 weeks after surgery,n=5).
