Dynamic Integrated CVD Risk Assessment

Intelligent Routing to MESA, QRISK3, ASCVD PCE or WHO HEARTS
⚙ Diagnostic Cascade: This engine prevents decision paralysis by actively selecting the most reliable cardiovascular risk model (MESA, QRISK3, ASCVD, or WHO) based on the clinical parameters and biomarkers you provide.

1. Core Demographics & Vitals

2. Lipid Profile (Required for ASCVD/QRISK)

3. Advanced Biomarkers & Comorbidities

⚠ Warning: Secondary Prevention Bypass
Never use ANY 10-year risk estimator (MESA, QRISK, or ASCVD) for a patient who already has established cardiovascular disease (prior MI, Stroke, Stent, CABG) or Familial Hypercholesterolaemia (LDL ≥ 190 mg/dL). These patients require immediate, high-intensity statin therapy (Secondary Prevention). Risk scores are strictly for Primary Prevention.

1. MESA (Multi-Ethnic Study of Atherosclerosis)

Trigger: Coronary Artery Calcium (CAC) Score > 0.

Pathophysiology & Why it Wins: ASCVD and QRISK are probabilistic—they guess risk based on risk factors. A CAC scan directly visualises actual, physical atherosclerotic plaque in the coronary arteries. If plaque is present (CAC > 0), the patient has disease, instantly overriding probabilistic models. A CAC of 0 is the most powerful "de-risking" tool available, often safely allowing statin deferral in borderline patients.

2. QRISK3 (UK Paradigm)

Trigger: Presence of RA, SLE, CKD, Severe Mental Illness, or Atypical Antipsychotic use.

Pathophysiology & Why it Wins: The standard American ASCVD PCE fails to account for systemic inflammatory burdens. Conditions like Rheumatoid Arthritis and SLE drive massive endothelial dysfunction and accelerated atherosclerosis via cytokine storms (TNF-α, IL-6). Atypical antipsychotics drive severe metabolic syndrome. QRISK3 natively ingests these variables, making it vastly superior for rheumatology and nephrology patients.

3. ASCVD PCE (American Paradigm)

Trigger: Standard lipid profile available, no systemic inflammatory modifiers.

Indian Context: The baseline ASCVD equation historically underestimates risk in South Asians by up to 20-30%. The Lipid Association of India (LAI) considers South Asian ancestry an independent risk enhancer. This engine applies a mathematically validated 1.2× scalar to the baseline ASCVD output for patients of Indian subcontinent descent to prevent statin under-utilisation.

4. WHO HEARTS (Resource-Limited Paradigm)

Trigger: Missing Lipid Profile (TC/HDL).

Utility: Designed for peripheral health centres or rural camps where blood tests are unavailable. It relies purely on age, sex, smoking, diabetes, and BMI/BP to deliver a pragmatic, non-laboratory risk estimate.
