Heart failure diagnostic criteria.

Framingham [3]	Boston [4]	European Society of Cardiology [60]	Gothenburg Score [5] Item and method of assessment
MAJOR CRITERIA Paroxysmal nocturnal dyspnea or orthopnea Neck vein distension Rales Cardiomegaly Acute pulmonary edema S3 gallop Increased venous pressure ≥ 16cm water Circ.time ≥ 25 sec Hepatojugular reflux MINOR CRITERIA Ankle edema Night cough Dyspnea on exertion Hepatomegaly Pleural effusion Vital capacity decreased 1/3 from maximum Tachycardia rate of ≥ 120/min) MAJOR OR MINOR CRITERION Weight loss ≥ 4.5 kg in 5 days in response to treatment HEART FAILURE present with 2 major or 1 major and 2 minor criteria	CATEGORY I: History Rest dyspnea (4pts) Orthopnea (4pts) Paroxysmal nocturnal dyspnea (3 pts) Dyspnea on walking on level (2pts) Dyspnea on climbing (1pt) CATEGORY II: Physical examination Heart rate abnormality (1–2pts) Jugular venous pressure elevation (1–2 pts) Lung crackles (1–2pts) Wheezing (3 pts) Third heart sound (3 pts) CATEGORY III: Chest radiography Alveolar pulmonary edema (4 pts) Interstitial pulmonary edema (3 pts) Bilateral pleural effusions (3 pts) Cardiothoracic ratio ≥0.50 (3 pts) Upper-zone flow redistribution (2 pts) Definite HEART FAILURE 8–12 pts, possible 5–7pts, unlikely 4 pts or less	Symptoms of heart failure (at rest or during exercise) and Objective evidence of cardiac dysfunction (at rest) and Response to treatment directed towards heart failure (in cases where diagnosis is in doubt). Criteria 1 and 2 should be fulfilled in all cases	CARDIAC SCORE
			History of heart disease (1–2pts)	Self-report
			Angina (1–2pts)	Self-report
			Edema (1pt)	Self-report
			Nocturnal Dyspnea (1pt)	Self-report
			Rales (1pt)	Physical exam
			Atrial fibrillation (1pt)	ECG
			PULMONARY SCORE
			History of Chronic bronchitis/asthma (1–2pts)	Self-report
			Cough, phlegm, or wheezing (1pt)	Self-report
			Rhonchi (2pts)	Physical exam
			Cardiac and pulmonary score are calculated and used to differentiate Cardiac form pulmonary dyspnea
