What do you people think of microdosing psilocybin and heart health?

I've read a few articles saying that while we do not know exactly the effects of microdosing psilocybin, it seems that it might affect the heart in e negative way.

Me and my girlfriend are microdosing psilocybin. While I take my capsule every other day, she takes it in a irregulate manner, whenever she remembers, probably a couple of times a week, never two consecutive days, and sometimes she tells me she has heart flutters.

What do you know about heart health in relation with microdosing psilocybin? Do you take something for heart health to balance out the potential negative heart effects of microdosing? Is this real or a myth?

My capsules are about 0.25g of Golden Teacher.
