Abstract

Objective: Shortness of breath is a common complaint for which the elderly seek medical attention in the emergency department (ED). Differentiating cardiac from respiratory causes of dyspnoea in this population is quite a challenge. N Terminal pro brain-natriuretic-peptide (NT proBNP) has been studied extensively as a biomarker of left ventricular (LV) failure. Methods: The NT proBNP was measured in 100 patients above 60 years of age who presented to the ED with shortness of breath. The level was compared with echocardiographic findings to assess correlation with ejection fraction (EF). Results: The NT proBNP values increased significantly as the functional severity of heart failure (HF) increased (P < 0. 001). The mean NT proBNP level was 1503. 33 pg/mL. Patients with respiratory causes of dyspnoea had a mean NT proBNP level of 309. 28 pg/mL with normal LV function. Conclusion: The NT proBNP levels had a good correlation with worsening LVEF. © 2012, Cardiological Society of India. All rights reserved.
