Why do the recommend low doses of aspirin to help prevent heart attacks? I dont have heart issues but I do have anxiety issues. Anxiety attacks feel like heart attacks so I have been told. I have had a few tests on my heart while having anxiety attacks and luckily my problem is just anxiety. However, my docs still tell me to take a low dose of aspirin daily. What does the aspirin do to help with heart health? How does it work and exactly what does it do to help prevent heart attacks ?
