Abstract | <p><b>BACKGROUND: </b>Sudden cardiac death (SCD), the cause of 250,000-450,000 deaths per year, is a major public health problem. The majority of those affected do not have a prior cardiovascular diagnosis. Elevated B-type natriuretic peptide levels have been associated with the risk of heart failure and mortality as well as with sudden death in women.</p><p><b>OBJECTIVE: </b>The purpose of this study was to examine the relationship between N-terminal pro-B-type natriuretic peptide (NT-proBNP) and SCD in the Cardiovascular Health Study population.</p><p><b>METHODS: </b>The risk of SCD associated with baseline NT-proBNP was examined in 5,447 participants. Covariate-adjusted Cox model regressions were used to estimate the hazard ratios of developing SCD as a function of baseline NT-proBNP.</p><p><b>RESULTS: </b>Over a median follow-up of 12.5 years (maximum 16), there were 289 cases of SCD. Higher NT-proBNP levels were strongly associated with SCD, with an unadjusted hazard ratio of 4.2 (95% confidence interval [2.9, 6.1]; P <.001) in the highest quintile compared with in the lowest. NT-proBNP remained associated with SCD even after adjustment for numerous clinical characteristics and risk factors (age, sex, race, and other associated conditions), with an adjusted hazard ratio for the fifth versus the first quintile of 2.5 (95% confidence interval [1.6, 3.8]; P <.001).</p><p><b>CONCLUSION: </b>NT-proBNP provides information regarding the risk of SCD in a community-based population of older adults, beyond other traditional risk factors. This biomarker may ultimately prove useful in targeting the population at risk with aggressive medical management of comorbid conditions.</p> |
