Abstract

Abstract: Objective To investigate the clinical characteristics of the elderly patients with acute pulmonary thromboembolism (APE) who showed low Wells score. Methods A retrospective analysis was performed on the risk factors, clinical characteristics and auxiliary examination results of 75 elderly patients with low Wells score who were suspected of APE in our hospital from January 2009 to August 2015. Among them, 21 patients finally diagnosed with APE were selected as the case group and the other 54 were selected as the control group. The influencing factors of APE in the elderly patients with low Wells score were analyzed by Logistic regression analysis. Results Compared with the control group, the proportions of the patients with chronic obstructive pulmonary disease (COPD) and coronary heart disease (CHD) in the case group were higher, and the clinical symptoms were mainly acute dyspnea, chronic dyspnea, chest tightness and chest pain (P<0.05 or <0.01). The levels of arterial oxygen partial pressure (PaO₂), arterial carbon dioxide partial pressure (PaCO₂) and International Normalized Ratio (INR) in the case group were statistically significant lower than those in the control group (P<0.01). Logistic regression analysis revealed that the independent influencing factors of APE in the elderly patients with low Wells score were COPD (95%CI: 1.421-261.620), PaO₂(95%CI: 0.883-0.984) and PaCO₂(95%CI: 0.782-0.972). Conclusions Clinical workers should pay attention to the elderly patients with low levels of PaCO₂ and PaO₂, or combined with COPD, even if they Wells score was low, it still need to be alert to the possibility of APE.
