Abstract

INTRODUCTION: Perioperative myocardial injury (PMI) is associated with increased mortality. We describe risk factors for and outcomes of PMI in patients undergoing tracheotomy.

METHODS: Retrospective study of patients undergoing tracheotomy from 2007 to 2016. PMI was defined by a postoperative cardiac troponin I (cTnI) > 99th percentile. Demographics and comorbidities were extracted from the electronic medical record and compared between patients with and without PMI. Significant univariate predictors were included in a multivariable logistic regression model to determine independent predictors of PMI. Thirty-day and 1-year mortality of patients with and without PMI were compared.

RESULTS: Of 861 patients undergoing tracheotomy, 41 (4.76%) had PMI and 820 (95.24%) did not. PMI was associated with higher mortality at both 30 days (40.5% vs. 11.2%,

CONCLUSION: Patients with PMI following tracheotomy had increased short- and long-term mortality. Increased age and history of prior MI were independent predictors of PMI, while cancer was associated with a lower risk of PMI following tracheotomy. ICU patients likely have more acute ailments contributing to a higher risk of PMI and poorer outcomes compared to cancer patients requiring tracheotomy. We propose routine screening for PMI with cTnI in the postoperative period in all tracheotomy patients.
