I was diagnosed at Mayo Clinic, a couple of years ago, with HFwpef. They're thinking it was due to chemotherapy 16 years ago. Now they're regularly testing anyone on my particular chemo drug regimen with this specific exercise test to uncover HFwpEF long term heart damage. But they didn't know that 15 years ago, so I was undiagnosed for a long time. My cardiologist put me on jardiance, metapropol, baby aspirin, and spironolactone. I went to cardiac rehab for six months, and graduated to seeing a Mayo physical therapist to manage exercise challenges.
Especially in this heat, and also having asthma, I am really discouraged.
