Hello @john6stodolka

I'm glad that you posted about this. I have a similar diagnosis as you and I also have a chronic dry cough. One of the groups of meds that are often used to treat this type of heart problem are called Ace Inhibitors. Perhaps you are taking one of those? I take Vasoctech which is an ACE Inhibitor. I've gotten used to the cough as I know the medication works really well to ease the burden on the heart. If you are comfortable sharing more information, what meds are you currently taking?

Here is some information from Mayo's website where you can see a list of the ACE Inhitibors and see if your med is one of them. As you can see, a cough is the first side-effect listed.

Will you post again?
