The Framingham Criteria for Heart Failure
The Framingham Criteria are classic clinical diagnostic criteria used to establish a diagnosis of heart failure. Unlike many modern tools that rely on echocardiograms or advanced laboratory assays, the Framingham criteria are purely clinical—based entirely on bedside history and physical examination findings.
To establish a formal diagnosis of heart failure using this system, a patient must concurrently manifest at least two major criteria OR one major criterion combined with two minor criteria.
Major Criteria
Paroxysmal nocturnal dyspnea (PND) or orthopnea
Neck vein distension (elevated jugular venous pressure)
Pulmonary rales (crackles on auscultation)
Cardiomegaly (enlarged heart demonstrated on chest X-ray)
Acute pulmonary edema
Third heart sound gallop (S3 gallop)
Increased venous pressure greater than 16 cm H2O
Hepatojugular reflux (positive test)
Weight loss of 4.5 kg or more over 5 days in response to treatment (diuretic therapy) for suspected heart failure
Minor Criteria
Minor criteria are only valid if they cannot be attributed to another concurrent medical condition (such as chronic obstructive pulmonary disease, liver cirrhosis, or localized venous insufficiency).
Bilateral ankle edema
Nocturnal cough
Dyspnea on ordinary exertion
Hepatomegaly (enlarged liver)
Pleural effusion
Decrease in vital capacity by one-third from maximum recorded value
Tachycardia (heart rate greater than or equal to 120 beats per minute)
Clinical Rule for Diagnosis
A clinical diagnosis of heart failure is satisfied if the patient fulfills either of the following combinations:
Combination A: At least 2 Major Criteria.
Combination B: 1 Major Criterion AND at least 2 Minor Criteria.
