Shouldnt be a prob. Might even exibit some pros as far as lowering gear induced bp issues. Ive noticed some anxiety issues on certain kinds of gear. so perhaps the blocking of epinephrine would reduce some of those symptoms to a degree.
my ex's mother had angina and i would swipe em whenever i had a chance. Controlled that fight or flight feeling that i had from speed withdrawl.
Anyway, should be fine. just ask your doc honestly.
