Severe aortic stenosis can cause chest pains. The angiogram will determine definitively if you have coronary artery blockages. In addition, an echocardiogram, which you have undoubtedly had as part of the work-up of aortic stenosis, would show whether you have had a major heart attack. If you had a very small heart attack, it could conceivably be missed unless you went to the ER right away. Good luck with your angiogram.
