Abstract
BACKGROUND: -Elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) is associated with clinically overt heart failure (HF). However, whether it provides additive prognostic information for incident HF beyond traditional risk factors and the left ventricular (LV) mass index among multi-ethnic asymptomatic individuals has not yet been determined. We studied the associations of plasma NT-proBNP and magnetic resonance imaging (MRI) defined LV mass index with incident HF in an asymptomatic multi-ethnic population. METHODS AND RESULTS: -A total of 5597 multiethnic participants without clinically-apparent cardiovascular disease underwent baseline measurement of NT-proBNP, and were followed for 5.5 ± 1.1 years. Among them, 4163 also underwent baseline cardiac MRI. During follow-up, 111 participants experienced incident HF. Higher NT-proBNP was significantly associated with incident HF, independent of baseline age, sex, ethnicity, systolic blood pressure, diabetes, smoking, estimated glomerular filtration rate, medications (anti-hypertensive and statin), LV mass index and interim myocardial infarction [HR 1.95 per 1 unit log NT-proBNP increment, 95% CI 1.54-2.46, p10%) =0.175, p=0.019; category-less NRI=0.561, phttp://www.clinicaltrials.gov.
