Hi @john6stodolka I see you joined Connect about a year ago, but this is your first post. I'd like to officially welcome you to Connect and thanks for joining the conversation. You will see I moved your discussion to an active post about heart failure with preserved ejection fraction, HFpEF. The benefit in doing this means you can connect with other members who are experiencing the same health concerns as you are and discuss your individual experiences. I would like to invite @robschweiger, @jakedduck1, @bjanderson, @ninimurphy, @predictable, @thankful, @hopeful33250 and @johnbishop to join once again and discuss any updates they may have or just to welcome you.

One of our mentors John also offered some reference information from Mayo Clinic that might be helpful in your search for answers.

The first link that has a presentation by Dr. Timimi does mention a cough as a symptom. When did you first notice the cough? Did s/he suggest anything for relief?

I have exactly the same issue. I have had a persistent cough for a few years now, yet they seem to think it’s not caused by my diastolic heart failure with preserved ejection. I have had a chest x-ray that was clear. I went to an ENT who thinks it might be silent reflux and I’ve been taking Pepcid for many months with no change at all in the cough. I really wonder if it isn’t a side effect of the blood pressure medication, my first one was lisinopril which made me cough like crazy. I switched then to losartan , and then eventually to valsartan. Although the cough was never as bad as on lisinopril, it has remained ever since.
