This is great if you have no problems with
side effects , but if you do, PLEASE let your
Doctor know. I am a 12 year CHF suvivor, had an initial EF of 18% which is not up 45%. During my adventure with heart diease I found I could not, and in some cases refused to tolerate a number of the most commonly prescribed drugs. Among them were coreg, any beta blocker, lipitor and others.
