Fleisher-Eagle Algorithm for Preoperative Cardiac Risk Assessment

Fleisher-Eagle Algorithm for Preoperative Cardiac Risk Assessment  
[select value="NO=0|YES=1" name="ischemic"]  <-- Ischemic heart disease (angina or prior MI)? 
[select value="NO=0|YES=1" name="chf"]  <-- Heart failure? 
[select value="NO=0|YES=1" name="riskysurg"]  <-- High-risk surgery (including intraperitoneal, intrathoracic, and suprainguinal vascular procedures)?
[select value="NO=0|YES=1" name="diabetes"]  <-- Diabetes mellitus (especially insulin-requiring)? 
[select value="NO=0|YES=1" name="renal"]  <-- Renal insufficiency?
[select value="NO=0|YES=1" name="poorfunc"]  <-- Poor functional status (defined as the inability to walk four blocks or climb two flights of stairs)?
