The new American Heart Association algorithm: is it progress?
The new 2014 American College of Cardiology (ACC) and American Heart Association (AHA) guideline for the perioperative cardiovascular evaluation and management of patients undergoing non-cardiac surgery was published in 2014.1 There are a number of fundamental changes to this guideline, of which the practising anaesthetist should be aware. Furthermore, the changes in the guideline give an idea of the change in the philosophy of cardiovascular risk stratification and risk reduction in the USA. This paper reviews the changes to the algorithm, and the publications that resulted in these recommendations.
