Feel grateful that your EF didn't get any worse. I am sort of in the same situation, diet, excerise and weight loss, except my EF drop from 45% to 40%. I understand there's a 5% room of error but it was depressing. I take 12.5mg of coreg 2x a day and 5mg of linisopril 2x a day. After my last echo I start taking CO-Q 10 that I have read a lot of good things about. I do try to compensate my workout for the coreg which slows your heart down. To my knowledge I never had a HA unless it was a silent one. My cardiomypathy may be genetic, I have never been tested for the cause, I am told it's the weakening of the heart muscle. Had a heart cath with good results. At 40%ef I am still able to live a normal life, so far. I am convince if I get to a point were as my quality of live and longevity is effected greatly I'll travel to Mexico for the gene therapy if I'm a candidate. I wish the FDA here would quit dragging their feet and approve it here in the US. Out of all the trials that I read about showed great results. Before I raise a lot of eyebrows, it would be a last ditch effort. I just seems like a lot of good medicine and therapy, maybe even cures gets placed on the back burners by the FDA.
