PURPOSE The American Society of Anesthesiology (ASA) classification remains the most widely used risk-stratification system in the world. However, it is not practical in patients undergoing revascularization procedures because most are classified as ASA III. We hypothesized that ASA III patients can be subdivided into two subgroups, ASA IIIA and ASA IIIB, simply based on their preoperative functional capacity measured in metabolic equivalents (METS) of <4 or > or =4, which would allow the… CONTINUE READING
