Myocardial cells and extracellular matrix fulfil their goal thanks to the energetic availability. Indeed, mechanical electrical properties of heart are strongly depended on production-consumption equilibrium. The produced energy is used under several forms including kinetic, dynamic, thermal etc. Notably, as time goes by; aging well in case failure, although total remains almost constant contribution each form altered. Thermal increased, whereas dynamic kinetic decreased hence unable satisfy adequately cardiac work. Consequently, toxic products, unfolded /misfolded proteins, free radicals accumulated within myocardium. cell contraction – relaxation coupling, ion exchange, growth function failed, control apoptosis necrosis lacking micro macro-architecture change final result. Energy production consumption depends metabolic resources functional status silhouette cardiomyocytes non-cardiomyocytes - behavior. Mitochondria, intra-cellular organelles producing more than 95% ATP fulfill all above prerequisites being thus very important such we have better understand anatomy, homeostatic properties.
