Well, there's a reason a screening EKG and sometimes periodic monitoring is recommended for people taking stimulants. There seems to be a general medical opinion that stimulants tax an already-taxed heart. It seems more ambiguous for people with healthy hearts. And given that obesity and drug addiction are common consequences of untreated ADHD, even if they are mildly cardiotoxic, they may still reduce the risk of heart disease when properly prescribed. (I'm no doctor, FWIW.)
