Patient selection: male referred for treadmill testing
Parameters:
(1) age in years
(2) history of acute myocardial infarction and/or Q waves on ECG
(3) history of congestive heart failure (CHF)
(4) exercise capacity in METs

Interpretation:
• minimum score: 0
• maximum score: 4
• The higher the score the greater the mortality.
