Hello. I was surprisingly diagnosed with HCM about 5 years ago when I was 65. After a big check up last November where I was told all was ok, stable, and come back in 6 months for another check up, I started to become more symptomatic late December. I was experiencing constant dizziness with chest discomfort. After it progressed to where I was out of breath while walking etc. I learned in early February 2020 that it had progressed to HOCM and was told the obstruction had changed and I needed a septal myectomy immediately. I had it done late February and am now recuperating. It was my dizziness and chest pains that made me more aware that the issue had changed. I hope this helps and it is not meant to alarm you, just to pay attention to symptoms and be proactive to take care of it. I thank my lucky stars I had it done before Covid became so pronounced. The week I returned home was when the world stopped which has become another issue of its own.
Good luck,
Barb.
