Three clinician-facing tools in one page. AF, PREVENT/Pooled Cohort risk, and device calculations run locally in the browser; entered values are not intentionally transmitted by this plugin.
Clinical use: Decision support only. Confirm indications against current guidelines, reversible causes, patient goals, prognosis, and specialist judgment.
ATRIAL FIBRILLATION
CHA₂DS₂-VASc + HAS-BLED
CHA₂DS₂-VASc
0 / 9
Stroke-risk score
HAS-BLED
0 / 9
Bleeding-risk score
Age
CHA₂DS₂-VASc
Age contributes 0 points.
HAS-BLED
Age >65 contributes 0 points.
Interpretation: HAS-BLED ≥3 flags patients for closer review and correction of modifiable bleeding risks; it should not by itself be used to deny anticoagulation.
PRIMARY PREVENTION
PREVENT™ + Pooled Cohort Risk
Browser-based implementation of the PREVENT base equations with optional comparison to the 2013 ACC/AHA Pooled Cohort Equation and the 2018 revised PCE. PREVENT estimates 10- and 30-year risk; PCE estimates 10-year ASCVD risk.
Clinical inputs
Eligibility / clinical caution: PREVENT is intended for primary-prevention adults ages 30–79 without known cardiovascular disease. Do not use in established CVD, severe subclinical CVD, end-stage kidney disease, or limited life expectancy. This implementation uses the PREVENT base model; optional HbA1c, UACR and SDI extensions are not applied.
Implementation reference: preventr 0.12.0 (MIT), implementing the AHA PREVENT equations and Pooled Cohort Equations. Results should be confirmed against an authoritative calculator before a treatment decision when clinically material.
