@jc76 Oh, thank you so much for taking precious time to offer me such an informative reply! It is so helpful to me to know that others with low EF are having the same issues. I don't feel so alone and afraid and it is so encouraging to know that life has gone on for you despite being diagnosed in 2000! I was diagnosed December 2025 but am sure I had this long before. I thought it was my lungs because gradually I was getting more and more winded when I was walking with my neighbor (5 days a week for 2-1/2 miles until one day I almost passed out and she helped me home. Haven't walked since.) I am hoping to start Cardio Rehab so I can get some exercise in because I am so afraid to overdo it and pass out. I sure missing walking each morning with my neighbor and I know my heart needs the exercise but not sure how much it can handle at this point. I guess it must be my blood pressure that is causing such dizziness and strange feelings in my body. I take Entresto twice a day and only 12.5 mgs Metoprolol because when I took 25 mgs my dizziness was even worse. I tried adding Jardiance but forget that! Even worse. I do have a blood pressure cuff and take it several times a day. It varies so much depending on how I am feeling and whether I've eaten enough, etc. I do feel very blessed that I was accepted at Mayo Clinic. I am meeting with an Electrophysiologist for the first time. May I ask if you have an ICD, Pacemaker or combo? This is my next hurdle. Thank you, again, for your kind reply!
