I believe cardiologists have gone back and forth on whether coffee is detrimental to their patients and I believe the consensus now is that it's pretty neutral with moderate consumption. Doctor's didn't tell me to limit hospital coffee when I was in heart failure in connection to covid. Strangely they didn't even mention the snus pouches they saw me use.
Coffee of course appears to confer many apparent health benefits, liver protection, antidiabetic, which could protect the CV system indirectly, and so on. Obviously excessive is bad for heart patients, but I remember when Redbull became popular the papers were full of stories of users ending up in the ER. It was speculated the taurine was the culprit. It was actually an elegant way to smooth out the caffeine stimulus and now they don't think it's bad, the taurine may be the reason I don't
feel energy drinks the same way I feel coffee. In Sweden they don't sell energy drinks to under 15s, but as far as I know there's no law against it, they collectively made that decision themselves. Some time ago a couple of fatty cashiers were telling me and my nephew, 21, how the energy drinks he purchased would kill us, "they are horrible for you."
Red Bull 
As kids we were buying the uncarbonated Thai bottles which Redbull was later based on. There were rumors they contained some illegal "speed" type drug. It was baloney.
