That sounds kind of worrisome, doesn't it? Have you had follow up yet with your doctor to go over these findings? Your SDS score still has you in the mild range for ischemia but I'm sure you'd like that score to be lower. Partially reversible could put you at a lower score, to even no ischemia. So, could be worth it! Your EF of 51% puts you just outside of borderline. This is probably going to get your doctor's attention. Can you tell me what they said? The shortness of breath is likely related to this and I'd consider treatment that they recommend. It sounds like you have ischemia to me based on what you've written which reduces cardiac function. But your doctor needs to give you that diagnosis. Do what they say! My friend had a heart Cath done and lived 20 years after. So, they CAN treat you. I take an angiotensin 2 and am working on cholesterol. Please update me, I'll be following.
