Cardiology medical calculators
Stroke prevention, ACS risk, and cardiac indices.
Cardiology calculators include CHA₂DS₂-VASc and HAS-BLED for anticoagulation discussions, HEART and TIMI for acute coronary syndromes, corrected QT, LDL estimation, and hemodynamic indices. Scores guide shared decision-making with patients; they should be applied with ECG, troponin, echocardiography, and guideline-directed therapy.

CHA₂DS₂-VASc Score
CHA₂DS₂-VAScEstimate stroke risk in nonvalvular atrial fibrillation to guide anticoagulation decisions.
Corrected QT (QTc)
QTcCorrect the QT interval for heart rate using Bazett or Fridericia formulas.
HAS-BLED Bleeding Risk Score
HAS-BLEDEstimate major bleeding risk in patients on anticoagulation for atrial fibrillation.
HEART Score for Chest Pain
HEARTRisk-stratify ED chest pain for short-term major adverse cardiac events using HEART.
LDL Cholesterol (Friedewald)
LDLEstimate LDL-C from total cholesterol, HDL, and triglycerides using Friedewald.
Mean Arterial Pressure (MAP)
MAPCompute mean arterial pressure from systolic and diastolic blood pressure.
TIMI Risk Score (UA/NSTEMI)
TIMIEstimate risk in unstable angina / NSTEMI using the TIMI risk score.
Wells Score for PE
Wells PEEstimate pretest probability of pulmonary embolism with the Wells PE criteria.
