Just like with vaccine regret and it not being helpful to go 'we told you so', this is another way to help and possibly save a life....
Trying to save a life is not the best time for might work and experimental/not known when there is something vetted and established that works.
You may be right for all I know but that is sorta the point, absolutely certain is always the better choice when it comes to life or death...
"Melatonin and methylene blue belong in every emergency medical kit. In cases of an acute heart attack or stroke, melatonin can help limit the damage, while methylene blue augments cytochromes to allow the continued production of ATP even without the use of oxygen, which also helps minimize cell death and tissue damage"

I think it's not a substitute for known protocols but a way to reduce damage to the heart. Personally I wouldn't take melatonin every day as some do but it's good to know it has a lot of benefits.
