I have heard and read that stress testing is not a good way to determine heart failure parameters and things like ejection fraction. If you want an eye-opening book that explains why that is read Beat the Heart Attack Gene by dr. Bradley Bale and Amy Doneen. The Echo is really the test to compute EF

I always upset when my Muga scan came back low. I had so many of those. But the girl doing the scan was so nice to me. Tee tests were so hard! They keep me awake. I was in a zone of somewhere. But they keep saying to me it's almost over. My heart is so with you. God bless you so much 🙏❤️

Thank you everyone 😍for all the information.

I just had my 2nd Muga. have had 3 echos, all read EF 30-35. My 2 stress test said over 50. This past Oct he said I would probably need another defib put in. Instead he has me wearing an external one for 😲at least 3 months,

My dr finally said that, He ordered another Muga scan.
