Figure 1. Cardiac troponin improves predicted risk of obstructive coronary artery disease in patients with suspected angina.

Figure 1

The red dots represent the risk of obstructive CAD as estimated by the established CAD Consortium model accounting for age, sex and symptom description. The blue dots represent the revised risk estimates with the addition of cardiac troponin quintiles. The shaded regions correspond to the risk groups and associated recommendations for further investigations as described in the ACC/AHA guidelines on the management of stable CAD.
