So I finally got my (fifth annual) echo results back today. The doctor told me that my mitral valve is leaking more than it did and that my overall heart function has weakened "a hair" in his words. Of course he left a voicemail and I haven't been able to get back in touch with the office today. As much as I don't welcome a second OHS, i'm not as concerned about the valve as much as I am with the EF. I've been staying around 50% which I suppose is the low end of normal. I don't want to lose any more because I know that it isn't easily recoverable. So any thoughts or advice you guys have would be greatly welcomed. Have any of you done anything that helped improve your EF? I know exercise is good from what i've researched and I plan to seriously amp up my cardio when I get the clear to do so.
