B-Type Natriuretic Peptide
B-type natriuretic peptide (BNP) and its inactive fragment NT-proBNP are critical biomarkers in the diagnosis, risk stratification, and management of heart failure and other cardiovascular conditions. The B-Type Natriuretic Peptide session explores the physiology of natriuretic peptides, their release in response to myocardial wall stress, and the many clinical scenarios in which measurement adds value. Participants will examine how BNP and NT-proBNP levels can distinguish cardiac from non-cardiac dyspnea, gauge severity of heart failure, and guide therapy over time. The session emphasizes practical interpretation in emergency, inpatient, and outpatient settings.
Many clinicians seek a cardiology conference to sharpen their understanding of test limitations and optimal use. This session reviews factors that influence peptide levels—age, obesity, renal function, atrial fibrillation, and right heart pressures—and how to adjust interpretation accordingly. Attendees will learn about recommended cut-off values in acute versus chronic settings, the role of peptide trends over time, and how natriuretic peptides integrate with imaging, physical examination, and other biomarkers. Real-world cases will demonstrate pitfalls such as falsely low levels in obese patients or elevated levels from non-cardiac causes.
A key focus is on natriuretic peptide–guided heart failure management. Participants will explore evidence on using BNP and NT-proBNP trajectories to assess response to diuretics, neurohormonal blockade, and device therapy. The session addresses how peptide data can inform decisions about hospitalization, discharge timing, and follow-up intensity in chronic heart failure clinics. Discussion will extend to their role in screening high-risk populations, refining prognosis, and identifying patients who may benefit from advanced therapies.
Beyond heart failure, the session touches on BNP use in conditions such as pulmonary hypertension, valvular disease, and cardiotoxicity surveillance. Attendees will gain practical tips for ordering tests appropriately, communicating results to patients, and avoiding overreliance on numbers without clinical context. By the end, participants will have a nuanced, evidence-based approach to incorporating B-type natriuretic peptide into daily cardiovascular decision-making.
