Can an Aspirin a Day Help Prevent a Heart Attack?

Since my stroke in July I have been on a low-dose "pirin" regiment (think Robin Williams, "The Birdcage" with Nathan Lane).  Being that I have also had 2 heart-attacks in the last 10 years, I never thought twice about my doctors recommendation and I was in no shape to question it. (Long story but I am not happy with the medical care I am receiving or received at the hospital ER.  Bare bones basics, and the ER twit doctor labeled me in his report as a "non-compliant patient with an excuse for everything" after a 10-15 minute 'consult' and not aware of my patient history.)

Now based on articles elsewhere (ie. U.S. Task Force Narrows Recommendation for Aspirin Use), one would think some new insight was recently discovered.  But alas, this is "old" news (from 2014) although still pertinent.

Scientific evidence shows that taking an aspirin daily can help prevent a heart attack or stroke in some people, but not in everyone. It also can cause unwanted side effects.

According to Robert Temple, M.D., deputy director for clinical science at the Food and Drug Administration (FDA), one thing is certain: You should use daily aspirin therapy only after first talking to your health care professional, who can weigh the benefits and risks.

The bottom line is that in people who have had a heart attack, stroke or cardiovascular problems, daily aspirin therapy is worth considering. And if you're thinking of using aspirin therapy, you should first talk to your health care professional to get an informed opinion, Temple says.

If your health care professional recommends daily aspirin to lower the risk of a heart attack and clot-related stroke, read the labels carefully to make sure you have the right product. Some drugs combine aspirin with other pain relievers or other ingredients, and should not be used for long-term aspirin therapy.
