RT Journal Article SR Electronic T1 Acute pulmonary embolism in patients of advanced age JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP p2355 VO 38 IS Suppl 55 A1 Thomas Berghaus A1 Wolfgang von Scheidt A1 Martin Schwaiblmair YR 2011 UL http://erj.ersjournals.com/content/38/Suppl_55/p2355.abstract AB Background: It has been speculated that the atypical clinical presentation of acute pulmonary embolism (PE) in older patients leads to a delay in diagnosis and therefore contributes to the worse prognosis of older patients presenting with acute PE.Methods: In this single-centre study we investigated the delay in diagnosis and its relation with in-hospital mortality in 202 consecutive patients with acute PE in a period of 14 months. The study population was divided in a younger (≤ 65 years) and an older age group (> 65 years).Results: Older patients present more often hypoxic (p = 0.017) and with a history of syncope (p = 0.046) than younger patients. Delay in diagnosis was not statistically different in both age groups (3.1±3.0 days in the younger and 3.5±3.1 days in the older age group, p = 0.450). Age above 65 years was significantly associated with an increased risk for in-hospital mortality (OR 4.36, 95% CI 0.93-20.37, p = 0.043). Delay in diagnosis was not associated with an increase of in-hospital mortality in univariate or multivariate analysis.Conclusions: The atypical clinical presentation of acute PE in patients older than 65 years cannot be considered as a risk factor for late diagnosis. Moreover, delay in diagnosis is not related to the higher in-hospital death rate of older patients suffering from acute PE.
