McKee 1971 Framingham CHF criteria
McKee 1971 Framingham CHF criteria. Definite if two major, or one major plus two minor, are concurrent. Nine major and seven minor caller-assigned flags. Weight loss ≥4.5 kg in 5 days in response to treatment is dual: major if that is definite, else minor if that is definite, else unused. major_count and minor_count are the fixed flags only. Not a medical device, not an echocardiographic diagnosis, and not HFrEF or HFpEF staging.
