What is Atherosclerosis?Diagnosis

Atherosclerosis is the slow process behind most cardiovascular disease — heart attack, stroke, peripheral artery disease, kidney disease, even some types of dementia. It starts decades before any symptom: LDL cholesterol particles slip into the artery wall, immune cells respond, and a sticky deposit called a plaque begins to grow. Over years it narrows the artery (causing angina, claudication, kidney damage) and — worse — can rupture or erode suddenly, triggering a clot that closes the artery in minutes. That is what a heart attack and most strokes actually are.

• The drivers are well-known — high LDL cholesterol, high blood pressure, smoking, diabetes/insulin resistance, obesity, sedentary lifestyle, family history, age, chronic inflammation. Sleep apnea, chronic kidney disease, and rheumatologic disease accelerate the process.
• It is silent for decades — the first symptom is often the heart attack or stroke. That is why prevention is the program: BP control, LDL control, no tobacco, healthy weight, exercise, glucose control. Each one slows the plaque biology directly.
• You can measure your "vascular age" — a Coronary Artery Calcium (CAC) score on a low-dose CT shows calcified plaque. Score 0 means very low 10-year risk. Score >100 means meaningful disease — therapy intensifies.
• Plaque is treatable — high-intensity statin, BP <130/80, A1C control, smoking cessation, a Mediterranean/DASH pattern, and 150+ minutes of weekly activity together can stabilize plaque and may even shrink it. Modern lipid-lowering (PCSK9, bempedoic acid, inclisiran) drops LDL further when needed.

Stable plaque vs. vulnerable plaqueKnow your plan

Not every plaque is equally dangerous. The plaques that rupture and cause heart attacks tend to be young, lipid-rich, and inflamed — often not the ones that look most narrow on imaging. The goal of medical therapy is not just to slow growth — it is to stabilize plaques so they do not rupture.

• Stabilizing biology — High-intensity statin, ezetimibe, PCSK9 inhibitor: lower LDL → less inflammation in the plaque cap → more stable.
• Stabilizing pressure — BP <130/80 reduces shear stress on the endothelium.
• Stabilizing glucose — A1C control reduces glycation damage to the artery wall.
• Stop the smoke — Quitting at any age reduces oxidative stress and endothelial damage; risk drops sharply within months.
• Move — Exercise improves nitric oxide signaling and endothelial function — the inside lining heals.

Your daily Force FieldLive It

• BP target generally <130/80 — daily home cuff. The single most evidence-backed lever in atherosclerosis.
• LDL target by risk — <100 for primary prevention, <70 with diabetes or other risk factors, <55 after any cardiovascular event. Statin first-line, ezetimibe and PCSK9 add-on as needed.
• No tobacco, no vaping — quitting at any age remains the single biggest behavior-change win.
• A1C <7% if you have diabetes — every point of improvement slows plaque progression measurably.
• Mediterranean / DASH eating — the dietary pattern with the most consistent atherosclerosis evidence.
• 150+ min/week moderate activity — improves endothelial function on its own.
• Treat sleep apnea + manage stress + protect sleep — overlooked accelerators.
• Consider a CAC score around age 40-55 if your team thinks risk is borderline — it can change the plan.

Red flags — call nowAction

• Call your clinic the same day for: new chest discomfort with exertion that goes away with rest (stable angina worth evaluating); a missed dose of antiplatelet or statin; medication side effects (muscle aches, bleeding, GI symptoms).
• Bring up at next visit: any change in exercise tolerance, lipid follow-up timing, BP log review, smoking-cessation support, depression screening, sleep concerns.
