Major noncardiac surgery is associated with a 5% incidence of serious cardiovascular complications and with a 1 to 2% probability of death from cardiac causes. Over the last few decades, researchers have assessed the perioperative predictive power of several risk indices. Research is currently focused on the evaluation of biomarkers. ⋯ High levels of preoperative and postoperative NT-proBNP are predictors of cardiovascular complications, including all-cause mortality, during the first 30 days after noncardiac surgery in adults with cardiovascular risk factors.

Observational Study
Intraoperative hypotension is associated with myocardial damage in noncardiac surgery: An observational study.
Perioperative myocardial damage and infarction (MI) is associated with increased mortality and other postoperative complications. ⋯ In a cohort of 300 patients undergoing major elective noncardiac surgery, there was a high incidence of myocardial damage and an association between an intraoperative reduction in SBP more than 50% from baseline lasting more than 5 min and myocardial damage.

Postoperative acute kidney injury (AKI) is the second leading cause of hospital-acquired AKI. Although many preventive strategies have been tested, none of them has been totally effective. ⋯ Intravenous hydration with 0.9% normal saline before major open abdominal surgery was not effective in preventing postoperative AKI. No safety concerns were identified during the trial.
