Objective: We aimed to evaluate the accuracy of the original and simplified Pulmonary Embolism (PE) Severity Index (PESI) to predict all-cause mortality after 30 days of acute PE diagnosis up to five years within consecutive sub-periods. Methods: Adult patients diagnosed with acute PE between January 1, 2003, and June 30, 2013, were retrospectively included. Data on baseline characteristics and mortality during a 5-year follow-up were collected. Results: The study included 414 patients (M/F=192/222). The median age at diagnosis was 61.5 (minimum-maximum, 18-93) years. Mortality rates were 13.3% at 30-d, 21.8% at 90-d, 32.6% at 1-year, and 51.0% at 5-year. Both stratification into risk classes according to the original PESI and low- vs. high-risk classification of original and simplified PESI were significantly correlated with 30-d, 31-90-d, 91-d-1-year, and 1-5-year mortality. Significant PESI predictors for mortality were history of cancer (HR=3.31, CI95%: 1.64-6.68; p=0.001) and heart failure (HR=2.35, CI95%: 1.04-5.32, p=0.041) at 31-90-d, history of cancer (HR=5.45, CI95%: 2.86-10.40, p<0.001) at 91-d-1-year, advancing age (HR=1.04, CI95%: 1.02-1.06, p<0.001) and history of cancer (HR=5.53, CI95%: 3.41-8.98, p<0.001) at 1-5-year after acute PE diagnosis. Conclusion: All-cause long-term mortality in high-risk acute PE patients according to original or simplified PESI significantly increased up to five years of follow-up. This survival disadvantage was mainly related to cancer and comorbidities rather than acute clinical manifestations. Future prospective studies are needed to demonstrate the effect of various comorbidities on long-term mortality in these patients.
