Well, the link you provided answered my question. Taurine can lower BP (through neural mediation), affect calcium in the heart and act as a diuretic. All of these would be contraindicated I think. I will ask my cardiologist when I see him next but I can already hear the answer. Not sure I would even want to upset the wagon at this point.

Sadly, this just emphasizes my point mentioned earlier that not all conditions can be treated naturally (diet, supplements, etc). Supplements have their own side-effects and care/caution needs to be taken when using them. This is just another example of certain instances where intervention with medicine (and most have some sort of nasty side-effects) is sometimes the only options. Even more sad is that many of the very medicines that are needed to help one problem, create another. I don't know what the answer is.
