Effects of chronic hypoxia on myocardial metabolism

Chronic hypoxia had widespread effects on myocardial metabolism. In understanding these effects, it is necessary to take account of the indirect ways in which hypoxia may act on the heart. Two such important indirect actions are those which follow the development of pulmonary hypertension and anorexia. The experimental design reported here enables one largely to distinguish the effects of pulmonary hypertension and anorexia from the rest. Using such a design, we have presented a number of diverse aspects of myocardial metabolism under conditions of chronic alveolar hypoxia induced by a low atmospheric pressure.
