Lifestyle first — and always
Lifestyle modification is the foundation under every other treatment, because it lowers several risk factors at once and has no downside. It does not replace medication when risk is high, but it makes every medication work better and is sometimes enough on its own when risk is low.
- Stop smoking. Quitting starts lowering risk within months and is the highest-value single change for a smoker.
- Move regularly. Aim for roughly 150 minutes of moderate physical activity a week — brisk walking counts.
- Eat for your arteries. Favor vegetables, whole grains, legumes, nuts, and fish; cut processed foods, refined sugar, and excess salt (salt especially affects blood pressure).
Controlling pressure and sugar
Two conditions deserve focused control because they silently damage arteries. Treating high blood pressure — through diet, exercise, and medication when needed — eases the strain that accelerates plaque. Managing diabetes protects vessels throughout the body; because diabetes is such a strong heart-risk condition, its targets and treatments overlap heavily with heart prevention.
Statins and how targets differ
Statins are the cornerstone drug of prevention. They lower LDL by reducing how much cholesterol the liver makes, and they also calm inflammation inside plaque, making it more stable and less likely to rupture. For most people at meaningful risk, the benefit clearly outweighs the small chance of side effects like muscle aches.
Here is where primary and secondary prevention split. In primary prevention, a statin is offered when your risk score is high enough to justify it. In secondary prevention — after a heart attack, stroke, or stent — risk is already proven high, so a high-intensity statin is standard and the LDL target is pushed much lower. The further along the disease, the firmer and the lower the target.
