Abstract

Introduction: The simplified PuImonary Embolism Severity Index (sPESI) score has been using to estimate the risk of 30-day mortality in patients with acute pulmonary embolism (PE). However, there is no trial studied the predictive value in long term outcome. The hypothesis of this study is sPESI score also has a predictive value of mortality rate at 1-year. Methods: Retrospective medical records review of 156 patients diagnosed with PE determined the severity by simplified pulmonary embolism severity index (sPESI). The high sPESI risk factors include age > 80 years old, history of cancer, history of chronic cardiopulmonary disease, heart rate > 110, systolic blood pressure < 100 mmHg, and oxygen saturation < 90%. The demographics, clinical manifestation, laboratory findings, 1-year mortality were collected and compared between high sPESI group and low sPESI group. Results: From 134 patients (mean 59.6 ± 19 years old, 42.9% male), 69 patients are in the high risk group, whereas 65 patients are in the low risk group. Overall, 22 patients died after 1 year. The 1-year mortality rates are 21.6% and 4.4% (p=0.02) in high risk and low risk group, respectively. Conclusions: From our analysis, we found that patient who has high sPESI score has higher mortality rate at 1 year compared to patient in low sPESI score. The sPESI score still has validation as prognosticator of PE at 1 year.
