I was diagnosed with heart failure at a 20% ejection rate in January 2020. No heart disease. But I have left bundle branch blockage. After a period of exercise follow up echocardiogram showed 40% ejection rate. I am wondering if, given no heart disease, if I can beat this thing? I continued exercise whereas I work out 4 to 5 days a week on cardio equipment. I give the exercise the credit and diet of course. Thanks George
