Bösner clinical decision rule to predict Coronary Artery Disease as a cause of chest pain
.....................................................................................................
Factors:

[select name="agesex" value="yes (1 point)=1|no (0 points)=0"] <-- Man 55 years or older OR Woman 65 years or older
[select name="vascular" value="yes (1 point)=1|no (0 points)=0"] <-- Known vascular disease (CAD, occlusive vascular disease, cerebrovascular disease)
[select name="exercise" value="yes (1 point)=1|no (0 points)=0"] <-- Pain worse with exercise
[select name="palpation" value="yes (1 point)=1|no (0 points)=0"] <-- Pain NOT elicited with palpation
[select name="assume" value="yes (1 point)=1|no (0 points)=0"] <-- Patient assumes pain is of cardiac origin
