Metoprolol
"I have an ascending aortic aneurysm and was put on metoprolol to help control chest pain and lower my heart rate. I've been on it 1 month and have about half a much pain and my heart rate has dropped from 100's down to 80's. Only side effected noted is mild dizziness every once in a while. I'd like to have no pain, but considering my situation that's not realistic so I'd say I'm happy with the results so far."
