A Prospective Evaluation of Natriuretic Peptide Based Referral of CHF Patients in Primary Care

This low interventional study, whose unique intervention was to measure the blood level of a biomarker called NT-proBNP in chronic heart failure patients daily followed-up by Primary Care Physicians (PCPs) in Europe, assessed if the cardiologist referral guided by NT-proBNP measurement in patients who were currently judged by PCPs as being stable, would lead to optimization of HF treatment, defined in adherence to treatment recommendations of the current European Society of Cardiology guidelines for the treatment of heart failure.
