Back in the 80’s...there was a drug called bretylium. In HUMAN studies...it suppressed or eliminated a very serious cardiac dysrhythmia known as ventricular febrillation. So successful it was called a “chemical defibrillator”...it was approved for human use in usa. Didn’t work. Off usa market for a long time now.
This study is done in isolated sheep heart muscle. This is a very long way from safe human use for the indication.
Only thing I could say is if it is used and the patient dies at least he will have a smile on his face if for a short time...(no pun intended)..
“In 2016, our study of patients with diabetes showed that incidental use of Viagra was linked with reduced heart attack risk and improved heart attack survival.”
Next point?
