What it is

Atherosclerotic cardiovascular disease is the buildup of cholesterol-rich plaque in arteries, which can narrow or block them and cause heart attacks, strokes, and peripheral artery disease. It develops silently over decades before any event.

Why it matters

ASCVD is a leading cause of death worldwide, yet it is largely preventable: it is driven by modifiable factors — chiefly ApoB-containing particles and blood pressure — and lowering them early and durably changes the trajectory.

An orientation to how this topic is typically approached — not medical advice.

Who is at risk

  • Elevated ApoB / LDL cholesterol
  • High blood pressure
  • Smoking
  • Diabetes
  • Elevated lipoprotein(a) (inherited)
  • Older age and family history

How it's diagnosed

Risk is estimated with clinical calculators and refined by tests such as a coronary artery calcium (CAC) score and lipid/inflammatory markers; established disease is confirmed by events or imaging (e.g., angiography).

  • ApoB / LDL-C / Lp(a)
  • Blood pressure
  • Coronary artery calcium score
  • hs-CRP
  • Risk calculators (e.g., pooled cohort / SCORE2)

Frequently asked questions

What's the single most important thing I can do?

Lower your ApoB (or LDL) and control blood pressure — the two most causal, modifiable drivers — as early as possible, and don't smoke. Measuring Lp(a) once reveals inherited risk that standard panels miss.

Is heart disease inevitable in my family?

Family history raises risk, including through inherited Lp(a), but ASCVD is largely driven by modifiable factors. Aggressively managing them can offset much of that inherited risk.

Evidence summary

That lowering ApoB/LDL and blood pressure reduces cardiovascular events is among the best-established causal relationships in medicine, supported by genetics and randomized trials across many therapies.
