Hello @bbuck,
Having access to ones lab results can be a blessing...or a curse...and both at the same time.
Unless you are medically trained to interpret these findings, it may cause confusion or result in more questions than answers. And you even mention you are now "scared!"
There is so much information out there about HCM and elevated Troponin/Pro BNP. There is definitely a link to these abnormal findings.
I was on beta blockers, didn't tolerate them.
Put on calcium channel blocker. Didn't tolerate them.
Put back on beta blockers.
It was a Merry-go-round of pharmaceuticals. And they never worked for me. Like you, I had to push myself to do anything. I was like a limp rag.

My advice to you is to be sure to go over these findings with your cardiologist. Have them address your concerns.
As long as they are up-to-date on all things HCM and HOCM they should be able to reassure you that these labs my not be normal, but "normal" for HCM. If there is any indication of HCM progression based on these results, they can go over that with you too.
HCM is a sneaky disease.
It can take years to progress. Or not progress at all. Or all of a sudden you need open heart surgery! It's good you are paying attention to yourself. You need to be your own best advocate in this HCM journey.

I am not an expert in anything, so there is no way I could answer your question regarding the Covid vaccine. There is a lot we just don't know yet...so not even going to venture out to attempt a guess!
That's my best answer!

When do you see your doctor again? Have they received the lab results too?
