Morise et al developed a score for determining the risk of coronary artery disease (CAD) in women based on findings during exercise testing. The authors are from West Virginia University.
Parameters:
(1) maximal heart rate in beats per minute
(2) ST depression during exercise
(3) age in years
(4) angina history
(5) current or prior smoking
(6) diabetes mellitus
(7) exercise-induced angina
(8) estrogen status

where:
• Since “prior smoking” could be almost anything, recent smoking will be used instead.
total score =
= SUM(points for all 8 parameters)
Interpretation:
• minimum score: -5
• maximum score: 105
• The higher the score the greater the risk for coronary artery disease (CAD).
