Response to Letter Regarding Article, “Myocardial Injury After Noncardiac Surgery and Its Association With Short-Term Mortality”
We thank Dr Xue and colleagues for their careful reading of our study1 on the association between postoperative myocardial injury and short-term mortality. In this study, we showed that postoperative myocardial injury, identified by routine troponin measurement monitoring, predicts short-term mortality after noncardiac surgery. By adjusting this association for preoperative variables known to predict mortality, we showed that myocardial injury was an independent predictor of mortality.
In response to the important comments raised by Dr Xue et al, we point out the following.
First, Dr Xue and colleagues state that the association reported may be confounded by other preoperative and intraoperative factors that were not adjusted for. We wish to underline that we aimed to determine the prognostic value of postoperative myocardial injury on the occurrence of short-term death to answer the question of whether patients at higher …
