摘要

in response to sustained hemodynamic overload, the heart initially compensates with an adaptive hypertrophic growth of the myocardium. Under prolonged stress conditions, the heart eventually develops irreversible changes that result in ventricular dilation and heart failure. At the cellular level, stress-induced cardiac hypertrophy is associated with an increase of myocyte cell size and activation of fetal genes encoding proteins involved in contractility, Ca~(2+) transport, and cell energetics (reviewed in Ref. 16).
