Show moreBackgroundA very high erythrocyte sedimentation rate (ESR) is usually an indication of underlying pathology. Additionally, a moderately elevated ESRmay also be attributable to biological ageing. Whether the ESR is a prognostic factor for mortality, regardless of age, has been scarcely investigated. Therefore, the objective was to analyse the association between elevated ESR levels and the risk of mortality in a prospective cohort of the general population.MethodsWe studied data from the Rotterdam Study (1990-2014). ESR levels were measured at baseline and individuals were followed until death or end of study. Associations between moderately (20-50mmh(-1)) and markedly (>50mmh(-1)) elevated ESR levels and all-cause mortality were assessed using multivariate Cox proportional hazard models.ResultsIn total, 5226 participants were included, and the mean age was 70.3years. During a median follow-up time of 14.9years, 3749 participants died (71.7%). After adjustment, both a moderately elevated ESR and a markedly elevated ESR were associated with a significantly higher risk of overall mortality [hazard ratio (HR) 1.23, 95% confidence interval (CI) 1.12-1.35 and HR 1.89, 95% CI 1.38-2.60, respectively]. Although the ESR becomes higher with age, in a group aged above 75years, without any comorbidities, an ESR>20mmh(-1) remained associated with a significantly increased risk of mortality (HR 1.29, 95%CI 1.01-1.64).ConclusionAn elevated ESR is an independent prognostic factor for mortality. Despite the fact that ESR increases with age, it remains associated with an increased risk of mortality and warrants close follow-up. Show less
