Welcome, @lpfnp. People with stiff heart often have high diastolic numbers, diastolic dysfunction. To help you connect with other members living with stiff heart, I moved your question to this existing discussion:

- Stiff Heart - diastolic heart failure https://connect.mayoclinic.org/discussion/stiff-heart-diastolic-heart-failure/

I did this so you can read previous posts and connect easily with members like @janet23 @deb2018 @tcokeefe @hopeful33250 @retirement75 @robschweiger @susikelley @susie7 @jam5 @mysisterbitme @annierae and many more.

I think you might appreciate also this video with Mayo Clinic's Dr. Timimi and the ensuing discussion among members.

Do you measure your blood pressure regularly? Has your cardiologist recommended any lifestyle changes to help manage the diastolic dysfunction?
