Hi,
Welcome to the ehealthforum and I am glad to help you out. I do understand the problems youâre facing due to the cardiomyopathy.
However, there shouldnât be any concerns in getting the tattoos done apart from the pain during the making of tattoos which anyone suffers. In no way does it interfere in the disease (cardiomyopathy) process.
You can go ahead with the tattoos if you intend to. I sincerely hope that helps. Take care.
