We appreciate the valuable comments on our study (1). As stated, early mortality after acute pulmonary embolism (PE) can be predicted using well-documented prognostic scores, including the original and simplified versions of the PE severity index (PESI) (2, 3). However, the data on long-term mortality are scarce (4). Due to the lack of such scoring for the late mortality after acute PE, we investigated the value of both versions of the PESI to predict long-term mortality in acute PE patients. Thus, our results reflect the usability of the PESI as an option to evaluate the longterm mortality after acute PE.
