In 208 patients with pulmonary embolism who were evaluated for 100-day mortality, Sen et al. studied complete blood counts, markers of renal function, c-reactive protein, and the simplified pulmonary embolism severity index (sPESI) scoring system and discovered that RDW and sPESI may be reliable guidelines for predicting 100-day mortalit (33). This evidence concerns the gene CRP and pulmonary embolism.
