How would you characterize this patient’s level of risk of suffering a fatal or nonfatal myocardial infarction in the next 14 days? Score: 1 = low risk, 2 = moderate risk, 3 = high risk;
How would you characterize this patient’s chest pain? Score: 1 = noncardiac, 2 = possibly cardiac, 3 = definitely cardiac;
Estimate the probability that this patient has significant coronary artery disease (CAD) (stenosis greater than 70%). Score: 1 = very unlikely to 5 = very likely;
How much does the patient’s opinion influence your decision to refer them for cardiac catheterization (CC)? Score: 1 = not very much to 5 = very much
