Abstract
AIMS
Dyspnoea is a well known symptom of acute pulmonary embolism (PE). We assess the prognostic role of different patterns of dyspnoea onset regarding in-hospital mortality, clinical deterioration and the composite of the outcomes in PE patients, according to their haemodynamic status at admission.
METHODS
Patients from the prospective Italian Pulmonary Embolism Registry (IPER) were included in the study. At admission, patients were stratified, according to their haemodynamic status, as high- (haemodynamically unstable) and non-high-risk (haemodynamically stable) patients.
RESULTS
Overall, 1623 consecutive patients (mean age 70.2 ± 15.2 years, 696 males), with confirmed acute PE, were evaluated for the features of dyspnoea. Among these, 1353 (83.3%) experienced dyspnoea at admission. No significant differences were observed regarding in-hospital mortality and the composite outcome of in-hospital mortality and clinical deterioration between patients with and without dyspnoea. However, in non-high-risk patients, clinical deterioration was more frequently observed when dyspnoea was present compared with absence of dyspnoea (P = 0.002). Multivariate Cox regression analyses showed that non-high-risk patients had an increased risk of clinical deterioration when experiencing dyspnoea within 24 h [hazard ratio (HR): 1.57, 95% confidence interval (CI): 1.49-1.65, P < 0.0001] and between 25 h and 7 days before admission (HR: 1.66, 95% CI: 1.58-1.77, P < 0.0001), independently of age, sex, right ventricular dysfunction, positive cardiac troponin and thrombolysis.
CONCLUSIONS
Non-high-risk PE patients experiencing dyspnoea within 7 days before hospitalization had a higher risk of clinical deterioration compared with those without and, therefore, they may require more aggressive management.
