Abstract MP05: N Terminal Pro B Type Natriuretic Peptide as a Stroke Risk Factor in the European Population: Results From the Biomarcare Consortium

Introduction: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a risk factor for atrial fibrillation and a marker of cardiac function used in detection of heart failure. Few studies evaluated the role of NT-proBNP as risk factor for stroke. Hypothesis: Given the link between cardiac dysfunction and stroke, NT-proBNP is a candidate marker of stroke risk. Our aim was to evaluate the association of NT-proBNP with stroke outcomes and to determine the predictive value beyond a panel of established risk factors for stroke. Methods: Based on the Biomarkers for Cardiovascular Risk Assessment in Europe (BiomarCaRE)-project we analysed data of 43,815 participants (48.3% men; mean age 52 yr) free of cardiovascular disease from 6 prospective population-based cohorts across Europe with a maximum follow-up of 22 years. All NT-proBNP measurements were performed on frozen samples in the central BiomarCaRE laboratory. The endpoints considered were validated fatal and non-fatal stroke. Results: We observed 565 stro...
