Plasma B-Type Natriuretic Peptide Levels in Ambulatory Patients With Established Chronic Symptomatic Systolic Heart Failure

Abstract

In the ambulatory care setting, both symptomatic and asymptomatic patients with chronic, stable systolic HF may present with a wide range of plasma BNP levels. In a subset of symptomatic patients (up to 21% in our cohort), plasma BNP levels are below what would be considered "diagnostic" (<100 pg/mL).
