The 2013 ACC/AHA Pooled Cohort Equations estimate the 10-year probability of a first hard atherosclerotic cardiovascular event (nonfatal MI, coronary death, or fatal/nonfatal stroke) in adults aged 40 to 79 without known ASCVD. This is a legacy equation: current AHA materials position PREVENT as the race-free tool for contemporary primary-prevention risk estimation.
A weighted score (0 to 9) that refines stroke risk in non-valvular atrial fibrillation beyond the older CHADS2 schema, adding vascular disease, age 65 to 74, and female sex. It identifies the low-risk patients who can safely avoid anticoagulation and stratifies everyone else.
A simple bedside score (0 to 9) estimating the 1-year risk of major bleeding in atrial fibrillation patients on antithrombotic therapy. Its main value is highlighting reversible bleeding risk factors, not vetoing anticoagulation in patients who need it.
A five-domain score (0 to 10) for adults presenting to the emergency department with chest pain, estimating the 6-week risk of major adverse cardiac events (MACE: death, MI, or coronary revascularisation). Low scorers can often be discharged early; high scorers warrant an early invasive strategy.
The QT interval shortens as heart rate rises, so it is corrected to a standard rate (QTc) before judging whether repolarisation is prolonged. This tool reports both the Bazett correction (the long-standing clinical default) and the Fridericia correction (more stable at extreme heart rates). Per the AHA/ACCF/HRS statement, a QTc at or above 450 ms in men or 460 ms in women is prolonged, and a QTc at or above 500 ms marks a substantially increased risk of torsades de pointes.
A seven-item bedside score (0 to 7) for unstable angina or NSTEMI that estimates the 14-day risk of a composite of all-cause death, new or recurrent myocardial infarction, and severe recurrent ischaemia requiring urgent revascularisation. Higher scores identify patients who derive more benefit from an early invasive strategy and potent antithrombotic therapy.
A score is a start. The product is asked.
Calculators give a number. When the patient in front of you needs the reasoning behind it, with the sources, the product does the looking-up.
Medical AI returns evidence-grounded answers backed by real citations. It is a reference tool, and these terms describe how it should and should not be used.
01 Educational purpose
Medical AI is an information and reference tool intended for educational use only. The answers it returns are not medical advice, diagnosis, or treatment. Always consult a qualified doctor or healthcare professional with any question concerning a medical condition.
02 Professional use
Medical AI is designed for use by practicing clinicians. It is not intended for direct patient use and is not a substitute for professional clinical judgment. Apply your own training and current guidelines to every decision an answer informs.
03 Privacy and data
We do not collect, store, or process personally identifiable patient information (PHI or PII). Do not enter names, dates of birth, medical record numbers, or any other patient identifiers into the composer.
04 Information currency
Medical knowledge evolves rapidly. Citations carry their publication date, so consult the primary source and the most recent clinical guideline before acting on anything material.
