[Exercise therapy for heart failure].
In chronic heart failure of CAD, therapeutic approach will be available either with drugs or exercise. With exercise, coronary risk factors such as BP, lipid, DM and obesity will be controlled. In addition, ischemia will also be controlled by decreasing oxygen demand related to BP and HR, and with increasing oxygen supply by increased ECNOS gene expression, collateral formation and regression of coronary stenosis. Infarct size is also reported to be decreased by increasing MnSOD in the cell by exercise. Prognosis of CHF is also good in various evidence of exercise therapy. Recent advances of molecular biology have revealed various mechanisms of exercise effect. Thus, exercise if properly prescribed without provoking ischemia will be basically and clinically effective therapy for patients with CHF.
