ASCVD Risco Cardiovascular (simplificado)

ASCVD risk: 10-year cardiovascular event probability

The ASCVD risk score tells you the 10-year probability that someone will have a first atherosclerotic cardiovascular event (MI, stroke, CV death). It runs on the Pooled Cohort Equations from AHA/ACC 2013, refined in later updates. What it asks for: age, sex, race, total cholesterol, HDL, systolic blood pressure, hypertension treatment, diabetes, smoking. Reading the result: <5% low, 5–7.5% borderline/moderate, ≥7.5% consider statin, ≥20% high. Example: take a 55-year-old man, non-smoker, treated HTN, total cholesterol 220 mg/dL, HDL 45, SBP 135 → the 10-year risk lands around 10–12%, moderate-high, so a statin is indicated.

Clinical context

It comes into play for primary prevention in adults aged 40–75 who have no established CVD. The score feeds the shared decision about starting a statin, the lifestyle conversation (diet, exercise, smoking cessation), and the BP and glucose targets you set. In Brazil, the Sociedade Brasileira de Cardiologia (SBC) leans on the Global Risk Score (an adapted Framingham) as its reference, though ASCVD gets cited all the time too. A word of caution: it overshoots risk in some non-white populations and undershoots in others, and risk enhancers like family history, CAC score, hs-CRP or Lp(a) can sharpen the call.

FAQ

Does ASCVD replace clinical judgment? No. It's a number to anchor the conversation with the patient, nothing more. Comorbidities, frailty and life expectancy still have to go on the scale.

Should I use ASCVD for someone with prior MI? No. Once CVD is established the patient is already high-risk, this is secondary prevention, and a high-intensity statin is indicated no matter what the score says.

What about ages outside 40–75? The equations were never validated below 40 or above 75. For young adults, look at lifetime risk instead; for older patients, tailor the decision around frailty and polypharmacy.

Do I need the lab values to use it? Yes. Total cholesterol and HDL are both required. Without the lipid panel, all you can manage is a rough, qualitative estimate.
