Dear Kennedy1,
I am glad to hear of the improvement in your heart since after discontinuing the diet drugs. I would suggest the continued use of an ACE inhibitor. There is not a lot of data on what happens to people after stopping these medications. All of the survival data showing benefit is on people who continued using ACE inhibitors. I would discuss this with your doctor, trying a different ACE inhibitor maybe reasonable.
Thanks for your question,
