Hubbard et al reported a score for predicting severe coronary artery disease in a patient based on simple clinical parameters. This can help to identify a patient who may benefit from more aggressive management. The authors are from the Mayo Clinic.
Outcome: 3-vessel or left main coronary artery disease
Parameters:
(1) sex
(2) history of myocardial infarction and/or Q waves
(3) typical symptoms of angina pectoris
(4) diabetes mellitus
(5) age in years

total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk for severe coronary artery disease (CAD).
