Recently, apoptotic biochemical process and signal transduction has been clarified, that is to say ,apoptotic pathway mediated either by mitochondria or death receptors activate caspase cascade to induce cell apoptosis. The mechanism that apoptosis regulated by mitochondria is widely supported. Myocardium is a kind of tissue with active energy metabolism, and containing abundant mitochondria. Mitochondial chief function is energy metabolism, which plays a vital role in maintenace of cellular physiological functions. Recent studies indicated that mitochondria were tightly related with cell apoptosis, and possessed function of regulating apoptosis. Abnormalities of mintochondrial metabolism includes alteration of energy metabolism pathways and injury of electron transport chain, but their relationship with apoptosis is undiscovered. When hypertrophied, myocardium energy metabolic model markedly cha
