Ischemic heart disease and resulting heart failure (HF) belong to the leading causes of death in developed countries. In order to prevent HF and improve clinical outcome in patients with myocardial infarction, novel therapies are required to protect the heart against the detrimental effect of ischemic injury. Due to the failure to translate numerous available experimental cardioprotective strategies into clinical practice, the need for novel protective treatments persists. We have, therefore, tried to apply a novel approach to cardiac protection against the postischemic HF induced in rats by ligation of the coronary artery. For this purpose, we have studied (i) the preventive and therapeutic effects of adaptation to continuous normobaric hypoxia (CNH; 12% O2) and exercise training (ExT; treadmill running), and (ii) the possible cardioprotective potential of epoxyeicosatrienoic acid (EET)-based therapy in order to attenuate the postischemic HF in rats. Adaptation to CNH and ExT is known for their cardioprotection in acute ischemia/reperfusion (I/R) injury manifested as reduction of infarct size. EETs exert antihypertensive effects and thus seem to be perspective for the research in clinically relevant models of cardioprotection in hypertensive animals. Our results have revealed that: - CNH prior to...
