In a Nutshell

Aspirin doesn't clean or remove arterial plaque but prevents heart attacks and strokes by inhibiting platelet clumping that forms clots on unstable plaque—essential for secondary prevention (post-heart attack/stroke/stent) and anyone with detectable plaque via calcium score, reducing recurrent events by ~20% with low-dose (81 mg) daily. Avoid routine use for primary prevention without plaque, as it raises bleeding risks; take at bedtime with food if stomach-sensitive, and skip if active bleeding, hemorrhagic stroke history, or aspirin allergy. Combine with lifestyle changes and supplements like nattokinase/berberine for optimal plaque stabilization, not replacement.

If you're taking a daily aspirin to prevent a heart attack or you stopped taking that aspirin because you heard it can cause dangerous bleeding. One of those choices is the right one. The other one causes increased risk. The aspirin decision depends on one critical question that most doctors never really ask: do you already have plaque inside your arteries? That single detail completely changes the aspirin decision.

Most heart attacks do not happen because arteries slowly close off. If they did, we'd be able to predict when a heart attack happens and exactly where it's going to happen because we would know how to find that plaque. We can't predict when or where a heart attack is going to happen. Most people that have a heart attack didn't have severely blocked arteries before. It happened in people with less severely blocked arteries because there's a lot more people with that. It's not really how much plaque you have that's causing this. It's something else.

Despite following the best diet at the time (low-fat diet was considered the best thing), exercising on a regular basis (long slow distance), arterial plaque still developed. That was a wake-up call.

If the artery's not fully blocked, what actually triggered that heart attack? It's plaque instability. Plaque sits quietly inside arteries for 20 or 30 years. Instead of a slow blockage, the plaque becomes unstable: leakage of soft plaque forms a clot. If the clot is big enough and goes to the heart, it causes a heart attack. If it goes to the brain, it causes a stroke.

Over time, cholesterol, inflammatory cells, and damaged tissue collect within these plaques when they're softening and getting inflamed. The body tries to seal that area off with a thin protective layer called a fibrous cap. For years, that cap might protect you from heart attack or stroke. But if that cap weakens or erodes, the body treats it like an injury inside the artery. Platelets rush to the area. Clotting proteins activate and a clot begins to form.

Platelets are tiny cells (technically without a nucleus). If you cut your finger, platelets rush to the area and form a clot, saving our lives every day. But the same system can cause problems inside arteries.

Think of plaque like a pimple under the skin of the artery. Tim Russert, longest-standing host of Meet the Press, died of a heart attack. Autopsy showed his arteries looked like the skin of a teenager with a bad case of acne. If the surface tears open, the body forms a clot that can block blood flow to the heart.

That's exactly where aspirin works. Aspirin makes platelets less likely to clump together. That effect lasts about 7 to 10 days.
