Perioperative cardiac complications pose the greatest risk to the estimated 100 million people undergoing non-cardiac surgery each year. Most of these complications are related to underlying pre-existing coronary artery disease (CAD). For over 40 years researchers have been studying perioperative cardiac risk and how best to estimate it. The goal ...

Valvular heart disease can be an important finding in patients presenting for noncardiac surgery. Valvular heart disease and resulting comorbidity, such as heart failure or atrial fibrillation, significantly increase the risk for perioperative adverse events. Appropriate preoperative assessment, adequate perioperative monitoring, and early intervention, should hemodynamic disturbances occur, may help ...

Perioperative myocardial infarctions occur in 1 to 4% of unselected noncardiac surgical patients, and are associated with high mortality. Detection of these events can be challenging, because 'typical' symptoms of myocardial ischemia may not be present or may be masked in the perioperative period. Therefore, surveillance by means of intraoperative ...
