High blood pressure, low energy -- a recipe for heart failure
...enses how much energy is needed. When a heart cell finds itself short on energy, say because it's being called on to contract harder or faster, its ERR is activated by an inducible co-activator called PGC-1, turning on genes that increase the heart's capacity to burn fats for fuel. In mice that lacked ERR...Cardio exercise benefits in male vs. female hearts
