RT Journal Article SR Electronic T1 The PESI, the simplified PESI and the shock index for identification of high-risk and low-risk patients with acute pulmonary embolism JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P3885 VO 40 IS Suppl 56 A1 Burcu Koyden A1 Fusun Alatas A1 Selma Metintas YR 2012 UL http://erj.ersjournals.com/content/40/Suppl_56/P3885.abstract AB We compared the test characteristics of the pulmonary embolism severity index (PESI), the simplified pulmonary embolism severity index (sPESI) and shock index (SI) for predicting 30-day outcomes in a prospective study of 132 patients with objectiveliy confirmed pulmonary embolism (PE). The primary outcome of the study was 30-day mortality.Overall, 13 (9,8%) out of 132 patients died during the first month. The SI classified fewer patients as high-risk (41 (31,1%) out of 132 patients, compared to sPESI (45 (34,1%) and compared to PESI (57 (43,2%). High-risk patients based on the SI had a higher mortality than those based on the sPESI and PESI (31,7% versus 22,2% and17,5%). Low-risk patients based on the SI had a lower mortality than those based on sPESI and PESI (0% versus 3,4% and 4%).The SI quantified the prognosis of patients with PE beter than sPESI and PESI.
