Prior probability of coronary artery disease | Investigative strategy and rationale |
---|---|
<10% (and/or non-anginal chest pain) | Trust your clinical judgement: no further testing for CAD |
10-30% | Rule-out test needed: CT calcium +/− CT angiography |
30-60% | Uncertainty: non-invasive functional imaging |
61-90% | Rule-in test needed: invasive coronary angiography |
>90% (with typical angina) | Trust your clinical judgement: no further diagnostic testing |
