cardiac risk index (CRI)

The cardiac risk index (CRI) is a numerical estimate of perioperative cardiac morbidity using Goldman criteria. Also see Revised Cardiac Risk Index, a simplifed risk score. observation Points history - age > 70 years 5 myocardial infarction within 6 months 10 physical - S3 gallop or JVD 11 aortic stenosis, hemodynamically significant 3 electrocardiogram (ECG) - rhythm other than sinus or PAC's on pre-op ECG 7 greater than 5 PVC's/min (any time prior to surgery) 7 poor medical condition 3 pO2 < 60, pCO2 > 50 mm Hg - K+ < 3.0 meq/L, HCO3- < 20 meq/L - BUN > 50 mg/dL or creatinine > 3 mg/dL (> 2 mg/dL [2]) - abnormal serum aspartate transaminase (AST, SGOT) - chronic liver disease - bedridden due to non-cardiac disease - operation - intraperitoneal, intrathoracic, aortic surgery 3 emergency surgery 4 - - total points 53 JVD: jugular venous distension PAC: premature atrial contraction PVC: premature ventricular contraction
