I just found out I have this condition. I had a stent placed in my left subclavian artery.. I mentioned that my symptoms have not come back but that I was still really out of breath with the least exertion. My doctor pulled up an echo from two years ago and said it showed diastolic insufficiency. I am scheduled for a new echo in two weeks. I also saw it written in my appt review that I have chronic diastolic congestive heart failure. That is why I am having a new echocardiogram. Not sure why this was missed since I kept telling them that I also get chest pain and palpitations. So I am in a waiting game to find out more. I think I am going to go to Mayo ‘s for a second opinion. I am on a beta blocker, a calcium channel blocker, a statin, a blood thinner and an aspirin. Thank you for the nice information. I will ask my cardiologist to order those tests. Please take care and thank you for responding. I am new at this posting program. Gibbs.
