Method of testing for heart failure risk
First Claim
Patent Images
1. A method of testing for heart failure risk in an asymptomatic patient, which comprises contacting a body fluid sample from the asymptomatic patient with an antibody which specifically binds to N-terminal Pro-ANF and detecting the formation of an immune complex by immunoassay, and comparing the peptide level thus obtained to control levels as an indication of said risk.

Abstract
The peptide N-terminal pro-ANF, which is present in body fluids such as plasma, has been found to be an effective predictor of heart failure and the invention provides prediction and screening methods based upon in vitro assaying of N-terminal pro-ANF in body fluids.

- 2. A method of screening asymptomatic patients, either for risk of developing heart failure, or lack thereof, which comprises contacting a body fluid sample from the asymptomatic patient with an antibody which specifically binds to N-terminal Pro-ANF and detecting the formation of an immune complex by immunoassay, and assessing the patient'"'"'s risk of developing heart failure upon the basis of said levels.
