It s not a good idea to discontinue such medication without discussing with your doctor first. You don t say what else you are receiving besides the aspirin, but I suspect they are protective drugs for your heart. Aspirin acts as a blood thinner and a small daily dose is strongly recommended in people who have had stents or heart attacks. You do have underlying heart disease which can continue to progress, even without symptoms for a long time. I recommend you talk to your cardiologist and get back on your medicines unless s/he tells you something different, Hope this helps.
