I now have sufficient information from the textbooks to compile a comprehensive answer. Here is a structured overview of all major cardiology risk scoring systems:
Major Cardiology Risk Scores
π« Acute Coronary Syndrome (ACS) / Chest Pain
TIMI Risk Score (UA/NSTEMI)
7 variables β 1 point each:
- Age > 65 years
- Known CAD (stenosis > 50%)
- β₯ 2 episodes of chest pain in 24 hours
- ST-segment or T-wave changes on ECG
- Elevated cardiac biomarkers (troponin/CK-MB)
- Aspirin use in prior 7 days
- β₯ 3 CAD risk factors (family Hx, DM, HTN, hyperlipidemia, tobacco)
Interpretation: Score 0β2 = low risk; 3β4 = intermediate; 5β7 = high risk for death/MI/revascularization at 14 days.
Used to determine need for early invasive strategy; score β€ 1 favors ischemia-driven (conservative) strategy.
β Goldman-Cecil Medicine; Washington Manual of Medical Therapeutics
GRACE Risk Score (ACS β NSTEMI/STEMI)
8 continuous variables (requires nomogram or calculator):
- Age
- Heart failure β Killip class
- Heart rate
- Systolic blood pressure
- ST-segment deviation
- Cardiac arrest at presentation
- Serum creatinine
- Elevated cardiac biomarkers
Key advantage: Better calibration than TIMI; includes hemodynamic status and renal function. Calculator at www.outcomes-umassmed.org/grace. High-risk score (> 140) favors early invasive strategy.
β Goldman-Cecil Medicine; Fuster & Hurst's The Heart 15e
HEART Score (ED Chest Pain)
5 variables β 0/1/2 points each (max 10):
| Variable | 0 | 1 | 2 |
|---|---|---|---|
| History | Non-specific | Mixed | Highly suspicious for ACS |
| ECG | Normal | Non-specific repolarization changes | Significant ST deviation |
| Age | < 45 yrs | 45β64 yrs | β₯ 65 yrs |
| Risk factors | None | 1β2 risk factors | β₯ 3 risk factors or known atherosclerosis |
| Troponin | β€ normal limit | 1β3Γ normal | > 3Γ normal |
Interpretation:
- 0β3: Low risk β early discharge
- 4β6: Moderate risk β observation + further evaluation
- 7β10: High risk β urgent/emergent intervention
Designed specifically for ED use; not validated outside ED.
β Rosen's Emergency Medicine
EDACS Score (ED Chest Pain β Alternative to HEART)
Derived from age, sex, history of CAD/risk factors, and chest pain descriptors (diaphoresis, radiation, pleuritic pain, reproducibility). Divides patients into "low risk" vs "not low risk" and pairs with serial troponin at 0 and 2 hours (EDACS-ADP).
β Rosen's Emergency Medicine
CRUSADE Bleeding Score (Post-MI)
Estimates major bleeding risk after NSTEMI for patients on intensive antithrombotic therapy. Variables include: female sex, older age, renal insufficiency, low body weight, tachycardia, extreme SBP, anemia, DM. β₯ 3 variables = high risk.
β Goldman-Cecil Medicine
π« Atrial Fibrillation
CHAβDSβ-VASc Score (Stroke Risk in AF)
Points:
| Factor | Points |
|---|---|
| Congestive heart failure | 1 |
| Hypertension | 1 |
| Age β₯ 75 years | 2 |
| Diabetes mellitus | 1 |
| Stroke/TIA (prior) | 2 |
| Vascular disease (MI, PAD, aortic plaque) | 1 |
| Age 65β74 years | 1 |
| Sex category (female) | 1 |
Annual stroke risk by score:
0 β 0% | 1 β 1.3% | 2 β 2.2% | 3 β 3.2% | 4 β 4.0% | 5 β 6.7% | 6 β 9.8% | 7 β 9.6% | 8 β 12.5% | 9 β 15.2%
Anticoagulation thresholds: Omit therapy at score 0; OAC recommended for men β₯ 2, women β₯ 3.
β Washington Manual; Braunwald's Heart Disease
CHADSβ Score (Older/Simpler AF Stroke Score)
CHF (1), HTN (1), Age β₯ 75 (1), DM (1), Stroke/TIA (2). Less granular than CHAβDSβ-VASc; largely superseded in current guidelines but still referenced for DOAC bridging decisions.
β Textbook of Family Medicine 9e
HAS-BLED Score (Bleeding Risk in AF)
Estimates 1-year major bleeding risk in anticoagulated AF patients:
- Hypertension (uncontrolled, SBP > 160)
- Abnormal renal or liver function (1 each)
- Stroke history
- Bleeding history/predisposition
- Labile INR (if on warfarin)
- Elderly (age > 65)
- Drugs (antiplatelets/NSAIDs) or alcohol (1 each)
Score β₯ 3 = high bleeding risk (not a contraindication to OAC, but prompts caution and correction of modifiable factors).
β Braunwald's Heart Disease; Fuster & Hurst's The Heart 15e
π« Coronary Artery Disease / Revascularization
SYNTAX Score (CAD Complexity)
Angiographic tool scoring coronary anatomy complexity for PCI vs. CABG decision-making. Summation of points per individual lesion across 16 coronary segments based on location, severity, bifurcation, calcification, thrombus, and tortuosity.
- Low SYNTAX (β€ 22): PCI reasonable
- Intermediate (23β32): CABG preferred
- High SYNTAX (β₯ 33): CABG strongly preferred
Used alongside clinical factors in Heart Team decisions.
β Sabiston Textbook of Surgery; Fuster & Hurst's The Heart 15e
EuroSCORE II
Estimates 30-day operative mortality for cardiac surgery. Variables include age, sex, renal impairment, extracardiac arteriopathy, poor mobility, prior cardiac surgery, chronic lung disease, active endocarditis, critical pre-op state, DM on insulin, NYHA class, CCS angina class, LV function, recent MI, pulmonary hypertension, urgency, and type of procedure.
β widely cited in surgical cardiology literature
π« Heart Failure
MAGGIC Risk Score
Predicts 1- and 3-year mortality in both HFrEF and HFpEF. Variables: age, EF, SBP, BMI, serum creatinine, NYHA class, DM, male sex, current smoker, COPD, HF diagnosis > 18 months, beta-blocker/ACEi/ARB use.
Killip Classification (Acute MI β HF Severity)
| Class | Description | Mortality |
|---|---|---|
| I | No HF signs | ~6% |
| II | Rales, S3, JVD | ~17% |
| III | Pulmonary edema | ~38% |
| IV | Cardiogenic shock | ~67% |
Used as a component in GRACE score.
β Goldman-Cecil Medicine
π« Pulmonary Embolism
PESI / sPESI (Pulmonary Embolism Severity Index)
sPESI (simplified) β 1 point each:
- Age > 80 years
- Cancer
- Chronic cardiopulmonary disease
- Heart rate β₯ 110 bpm
- SBP < 100 mmHg
- SpOβ < 90%
Score 0 = low risk (30-day mortality ~1%) β outpatient treatment candidate
Score β₯ 1 = high risk β hospitalization
