I'm not sure what to do next, or what to think:
I am a 51 year-old male with a family history of cardiomyopathy (Father and older sister). I had an EKG which led me down the path of having an echo-cardiogram and radio-isotope stress test. The echo showed 45% ejection fraction, and the stress test said there was "evidence of a previous heart attack". I have not had a heart attack to my knowledge.
So yesterday I had a heart catheter in which I was told there was only 25(ish) percent blockage with a 50% ejection fraction. This was done by a different specialist than my regular cardiologist, and was given minimal information.
I am supposed to have a follow-up with my regular cardiologist in three weeks, and was told not to worry about anything.
Just FYI - I am not overweight, and am athletic (bicycle rider). With an EF of 45% or 50% with my history, I am not sure what to do to keep on top of things. I do get tired and feel the need to nap every day, which came on over the last year or so.
I am trying to decipher if I am borderline caridomyopathy, or what to do in order to get myself back to a place where I am not exhausted and feel "normal" again. I'm at a loss as to what to do next.
Any advice would be helpful. Thank you for your time.
