Here is a complete, textbook-verified summary of the Framingham Criteria for CHF:
Framingham Criteria for Congestive Heart Failure (CHF)
Diagnosis requires: 2 major criteria OR 1 major + 2 minor criteria
Major Criteria
| # | Criterion |
|---|---|
| 1 | Paroxysmal nocturnal dyspnea (PND) or orthopnea |
| 2 | Neck vein distension (elevated JVP) |
| 3 | Pulmonary rales (crackles) |
| 4 | Cardiomegaly on chest X-ray |
| 5 | Acute pulmonary edema |
| 6 | S3 gallop |
| 7 | Increased venous pressure (>16 cm H2O at right atrium) |
| 8 | Positive hepatojugular reflux |
| 9 | Weight loss >4.5 kg in 5 days in response to treatment* |
*This is classified as "major or minor" criterion in some sources (Braunwald's), but counted as major in the original criteria.
Minor Criteria
| # | Criterion |
|---|---|
| 1 | Bilateral ankle edema |
| 2 | Nocturnal cough |
| 3 | Dyspnea on ordinary exertion |
| 4 | Hepatomegaly |
| 5 | Pleural effusion |
| 6 | Vital capacity decreased by ≥1/3 from maximum |
| 7 | Tachycardia (HR >120 bpm) |
Important caveat: Minor criteria are only valid if they cannot be attributed to another medical condition (e.g. pulmonary hypertension, COPD, cirrhosis, ascites, nephrotic syndrome).
Diagnostic Performance
| Parameter | Value |
|---|---|
| Sensitivity | 97-100% |
| Specificity | 78-79% |
The high sensitivity makes this tool best for ruling out heart failure. However, it is relatively non-specific.
Limitations
- Less sensitive for early or mild HF
- Not well-validated for HF with preserved ejection fraction (HFpEF)
- Subjective clinical findings (rales, JVP estimation) carry inter-observer variability
- Does not account for comorbidities that mimic HF features
Modern Context
In current practice, the Framingham criteria are supplemented with:
- BNP / NT-proBNP (highly sensitive biomarker)
- Echocardiography (to assess EF and classify HFrEF vs HFpEF)
- CXR for pulmonary congestion and cardiomegaly

Based on exhaustive searching through Harrison's Principles of Internal Medicine 22nd Edition, here is the honest answer:
Framingham Criteria in Harrison's 22nd Edition - Honest Finding
Harrison's 22nd Edition (2025) does NOT include a dedicated Framingham Criteria table or checklist for CHF diagnosis.
This is a well-known characteristic of Harrison's - it focuses on the pathophysiology, clinical features, and modern diagnostic approach to heart failure rather than reproducing the classical Framingham scoring table. The 22nd edition's HF chapter (Chapter 264) covers diagnosis through:
What Harrison's Does Cover on HF Diagnosis
Symptoms described in detail:
- Dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea
- Fatigue, reduced exercise tolerance
- Nocturia, oliguria (advanced disease)
- Peripheral edema, abdominal distension
Physical exam findings (from the Physical Examination section, p. 2027):
- Elevated JVP - quantified as height of venous column >8 cm H2O; positive hepatojugular reflux
- Pulmonary rales - heard at lung bases; throughout lung fields in severe HF
- Bilateral pleural effusions - dullness to percussion at bases
- S3 gallop - present with volume overload and tachycardia; carries negative prognostic significance
- S4 gallop - suggests HFpEF
- Pulsus alternans - sign of severe HF
- Displaced apical impulse, right ventricular heave
- Cardiomegaly on CXR
Harrison's modern diagnostic approach instead relies on:
| Tool | Role |
|---|---|
| BNP / NT-proBNP | Most sensitive biomarker; primary diagnostic tool |
| Echocardiography | Assess EF, classify HFrEF vs HFpEF vs HFmrEF |
| Chest X-ray | Cardiomegaly, pulmonary congestion |
| ECG | Arrhythmia, LVH, ischemia |
| Comprehensive metabolic panel, CBC | Rule out precipitants |
Why the Framingham Criteria Are Not in Harrison's
Harrison's editorial position is to present evidence-based, current clinical management. The Framingham criteria (originally published by McKee et al. in 1971 from the Framingham Heart Study) are primarily used in epidemiological/population screening contexts. In modern clinical practice, Harrison's 22nd ed. emphasizes that the diagnosis of HF should be confirmed with natriuretic peptides and echocardiography, not clinical scoring alone.
If you specifically need the Framingham criteria table as a diagnostic checklist for an exam or clinical reference, it is best sourced from Braunwald's Heart Disease (Table 50.4) or the original McKee et al. 1971 paper, as covered in the previous answer. Harrison's simply does not present it as a named criteria set.
