Abstract
To analyse the clinical characteristics and to explore the prognostic factors of acute pulmonary thromboembolism in the elderly. The medical records of inpatients with acute pulmonary thromboembolism discharged from Peking Union Medical College Hospital from January 1, 2012, to February 1, 2019 were retrospectively reviewed. The eligible patients were divided into elderly group (≥ 60 years old) and non-elderly group (<60 years old). The clinical symptoms, complications, laboratory results, pulmonary embolism severity index (PESI) and mortality were compared between the two groups. Mortality was further compared among elderly patients of different age groups. Cox regression analysis was used to analyze the risk factors of 7-day and 30-day death in elderly patients with pulmonary embolism. A total of 503 patients with acute pulmonary embolism were included, including 279 cases in the elderly group and 224 cases in the non-elderly group. The incidence of cardiac arrest was higher in the elderly group compared with non-elderly group, while the incidence of chest pain and hemoptysis was less common in the elderly group. The proportions of comorbidities, including diabetes, hypertension, and coronary heart disease were higher in the elderly group while the proportion of autoimmune diseases was higher in the non-elderly group. In terms of prognosis, the PESI score and 7-day and 30-day mortality in the elderly group were higher than those in the non-elderly group. The mortality of elderly patients increased with age. Cox univariate regression analysis showed that infection, hypoalbuminemia, hypocalcemia, elevated cardiac troponin(cTnI), elevated N-terminal prohormone of brain natriuretic pepride(NT-proBNP) and PESI grade were associated with 30-day death. Multivariate Cox regression analysis showed that PESI grade and decreased serum calcium concentration were independent risk factors for 7-day death of pulmonary embolism in elderly patients. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death. The mortality of elderly patients with pulmonary embolism was higher than that of non-elderly patients, and the mortality increased gradually with age. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death of pulmonary embolism in elderly patients.
