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

<-- Man 55 years or older OR Woman 65 years or older
<-- Known vascular disease (CAD, occlusive vascular disease, cerebrovascular disease)
<-- Pain worse with exercise
<-- Pain NOT elicited with palpation
<-- Patient assumes pain is of cardiac origin
