Hello again, @poppy0344,

I certainly applaud you for all the research you are doing. It is very important these days to be your own advocate for your health needs. Doctors only have a certain amount of time to listen to their patients and research. It is vital that we help them to take care of us. Most doctors worth their salt will not object to you bringing in your research.

Yes, please look at the ACE inhibitors meds. It is especially useful for heart failure with minimal side effects and fewer problems to the kidneys than other meds of its type. It relaxes the heart and helps it to function better.

Here is some info about ACE meds from Mayo's website,

As ACE meds relax the veins and arteries it also relaxes me all over, so I take it at bedtime.
