I do not have HFpEF. My case is simular to katekateny in that I have no co-morbidities, naturally low blood pressue, 98/64 this morning, no hardening of arteries, or plaques in my heart vessels, no history of family heart disease, perfect blood chemistry except for calcium score of 40. I was completely healthy. Then in 2023 I started being exhausted all the time, I got dizzy at work whenever I got up from my desk and fainted a few times. I couldn't breathe lying down, couldn't go on bike rides with my husband because I would get dizzy even at a moderate to slow pace. My Physican's Assistant at my annual exam took an EKG and immeditely corrected diagnosed left vententricular abnormality. It took 10 months to get into a cardiologist due to my health insurance. Cardioligist 1, flummoxxed said maybe an unknown virus, so went to Mayo for consult, Mayo cardiologist also said maybe a virus. Still no clear reason.
