I have the same thing but 6%. I was prescribed the same things. This all just happened within the last week for me. The Cardiologist said that mine is like a 6% chance of having a heart attack right now. So, I'm assuming yours is 15%. I'm hesitant on taking the Amlodipine because it lowers blood pressure and mine is already low. As far as drinking, I wouldn't advise it especially with the Isosorbide, that is basically Nitroglycerin in a daily form. I'm not a Doctor but I hope this helps you! Good luck.
