Plasm N-terminal pro-B-type natriaretic peptide (NT-proBNP) levels and severity of coronary artery lesions in patients with acute coronary syndrome / 解放军医学杂志

ABSTRACT

Objective To investigate the relationship between plasm N-terminal pro-B-type natriuretic peptide(NT-proBNP) levels and severity of coronary artery disease and coronary artery lesions. Methods 150 patients complaining of chest pain and suspected to have coronary artery disease (CAD) were enrolled in the study. Plasm NT-proBNP contents were determined with ELISA method within 48h, and left ventricular ejection fraction (LVEF) was assessed with echocardiography 5-7 days after admission. All patients underwent coronary artery angiography(CAG) 2-17 days after admission and the severity of coronary artery lesions was estimated by coronary angiographic Gensini scores. According to the clinical data and results of CAG, 78 patients were diagnosed as acute coronary syndromes (ACS), 33 patients as stable angina, and 39 patients in whom angiography showed negative findings, served as normal controls. The correlation of plasm NT-proBNP levels with clinical severity of coronary artery disease and Gensini scores were analysed. Results Plasm NT-proBNP levels in patients with ACS, stable angina and in normal controlls were 526.96?376.90, 95.61?56.32 and 41.75?24.26pg/ml,respectively(P
