Ask the doctor. My father has severe heart failure. The doctors say his ejection fraction is only about 10%, and he gets short of breath during any physical activity. I've read that beta blockers are useful for heart failure, but his doctors say they're too risky for my father. I'm worried that he's missing out on a beneficial treatment.
