ABSTRACTHamilton Morris kommenterar studien om koppling mellan psilocybin och kardiotoxicitet:
European countries. The important source of those psychodysleptics may be a spreading growth of Psilocybe genus mushrooms. Material and Methods: To verify a previously published hypothesis on cardiotoxicity of hallucinogens, the experimental study in the form of a three-month test on male Wistar rats was performed. The study groups received intraperitoneally psilocin (PSI) in a dose of 10 μg/kg body weight (b.w.) or beta-phenylethylamine (PEA) in a dose of 1 mg/kg b.w. dissolved in 5% ethanol every second day for 2 and 12 weeks. The control groups received 5% ethanol or 0.9% solution of NaCl for the same time periods. At the end of the experiment, biochemical blood parameters, ECG, and myocardial energetic status were examined, as well as histopathological and electron-microscopic examinations were performed. The decreased serum magnesium concentrations in the PSIexposed animals were noted. Results: The obtained results showed that the repeated (12 weeks) administration of PSI produces in rats ECG abnormalities in the form of tachycardia, myocardial ischaemia and aberrant intraventricular conduction. It was also stated that long-term exposure to PSI and PEA exerts a crucial effect on the energy heart muscle metabolism, which has been reflected in the complex changes in the myocardial profile of purine concentrations. These abnormalities corresponded with degenerative changes in cardiomyocyte mitochondria observed on histopathological and electron microscopy examinations. Conclusions: The results of the study indicated a cardiotoxic effect of psilocin, manifested by functional and structural changes in cardiomyocytes and coronary arteries.

"Like most animal tox studies the dosing regimen does not accurately reflect "normal" patterns of human use, it would be very unusual for anyone to ingest psilocin every other day for 12 weeks, though what is impressive about the study you linked is the very low dose of psilocin administered, which would actually be sub-psychedelic if dosed equivalently in humans.
I certainly do think it's possible for long term, frequent, or high dose use of some psychedelics and empathogens to cause heart valve damage. This is probably more of a concern for people who consume large quantities of 6-APB, DOB or similar high affinity full agonists of 5HT2B, but psilocin could also be a concern if it were used very frequently. So...yeah, don't ingest psilocin everyday would be the takeaway I suppose. "
