Abstract
BACKGROUND: Pulmonary embolism (PE) is associated with high short-term mortality in elderly patients, even when hemodynamically stable. METHODS: One hundred and seventy hemodynamically stable patients with confirmed PE (41<65years and 129≥65years) were prospectively followed for one month in order to assess whether comorbidities can predict short-term mortality in elderly patients. Upon admission, patients' clinical characteristics (including instrumental and laboratory parameters) were evaluated, and two clinical scores were calculated: the Cumulative Illness Rating Scale (CIRS), commonly used to evaluate comorbidities in elderly patients, and the Pulmonary Embolism Severity Index (PESI). RESULTS: Fifteen patients (all elderly) died within one month from their PE diagnosis (mortality rate=8.8%; 95%CI:4.6-13.1%). In these non survivors, arterial partial oxygen pressure (p<0.0001) and saturation (p<0.0001), pH (p=0.001) and systolic blood pressure (p=0.017) at admission were significantly lower than in survivors, whereas their respiratory rate (p<0.0001), white blood cells (p<0.0001), lactate dehydrogenase (p<0.0001), troponin T (p=0.001) and D-dimer (p=0.023) were significantly higher. CIRS correlated with PESI (rho=0.54, p<0.0001), and was higher in non-survivors (p=0.002). The age- and sex-adjusted odds ratio of 1-month mortality was 1.91 (95%CI:1.24-2.95) for every 1-point increase in CIRS. The AUC was 0.78 (95%CI:0.67-0.89) for the logistic model containing CIRS, and 0.88 (95%CI:0.79-0.96) for that containing PESI (p=0.059). CONCLUSIONS: In elderly patients with PE, CIRS demonstrated a fairly good performance in predicting short-term mortality. Its easiness and suitability for use in common clinical practice make CIRS a potentially useful prognostic score for short-term mortality in these patients.
