A 72-year-old man with a history of type 1 diabetes mellitus and coronary artery disease is scheduled to undergo aortobifemoral bypass surgery. As part of preoperative bloodwork, an N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement is performed and the result is 80 pg/mL. Based on a recent trial evaluating the predictive value of preoperative NT-proBNP, which of the following BEST describes the relationship between the composite of 30-day all-cause mortality or myocardial infarction and preoperative NT-proBNP?
Myocardial injury after noncardiac surgery (MINS) is a significant cause of morbidity and mortality. Several indices have been developed to predict the risk of cardiac complications after surgery based on preoperative variables involving the procedure type and patient comorbidities. Among the most popular are the Revised Cardiac Risk Index (RCRI) and the National Surgical Quality Improvement Program Myocardial Infarction and Cardiac Arrest calculator. In general, these indices have been shown to underestimate risk. N-terminal pro-B-type...
