Abstract
Background: Heart failure (HF) is one of the leading causes of hospitalizations in both developed as well as developing nations. The natriuretic peptide N-terminal pro-BNP (NT-proBNP) has long been used for diagnosing and managing HF. The study aimed to determine the correlation of NT-proBNP levels with clinical and echocardiographic features in evaluation of patients admitted with heart failure.
Methods: This is retrospective observational study of 37 patients admitted to the hospital with acute onset dyspnea, over a period of 18 months. In addition to detailed history and physical examination, complete blood counts, random blood sugar, blood biochemistry, and electrocardiography (ECG), bedside echocardiography and x-ray chest were performed on admission to the hospital. Measurement of serum NT-proBNP level was performed as part of evaluation of dyspnea.
Results: Average age of the study population was 64 years. The co morbidities among the patients were hypertension (91%), diabetes mellitus (68%), obstructive airway disease (21%), coronary artery disease (16%) and chronic kidney disease (4%). The mean NT-proBNP for each group was LVEF ≥ 50%= 2272, LVEF 40–49% = 8161.5, and LVEF < 40% = 17302.7 (pg/ml).
Conclusion: NT-proBNP levels are proven to be useful in diagnosing and management of heart failure. However, the levels can be affected by many factors such as age, renal function, anaemia and body mass. When interpreting NT-proBNP levels, these factors have to be taken into account while making clinical decision and initiation of appropriate therapy.
