I think it is rather reactionary of you guys to see the word "heart" and automatically assume they should never take drugs
Obviously, no one here would be fit to give advice to you though... as we simply aren't doctors. OP, you would really be better off asking your doctor (and they will probably say no no matter what

). If you aren't comfortable with doing that, then you probably shouldn't risk it at all.
Also, "molly" isn't a drug.... MDMA is sometimes sold under that name, but more often than not meth, methylone, mephedrone and other cathinone stimulants and research chemicals ("bath salts") make their way into capsules to be sold as "molly"
MDMA might be an alright drug to take with your condition... but meth? HELL NO.
wll I used to do ecstacy a lot whn I was 18 but now..... I have palpitations but I really want to do it uggh but I don't no

this sux its the end of the world guys I gotta party
Many people have rolled with this condition and have come out just fine. But, the risk of complications and even death is extremely high. Ask your doctor, seriously. If by some miracle he says yes, then go ahead

Otherwise you're taking your life into your hands.
