Clinical Scorecard: CT Imaging Advances: Non-Invasive Detection of Coronary Artery Disease Through ESR Bridges

At a Glance

Key Highlights

• CT shows high diagnostic accuracy compared to invasive coronary angiography (ICA) for detecting CAD.
• CT use leads to improved patient outcomes including reduced death or non-fatal myocardial infarction in stable chest pain patients.
• CT enables better prevention, individualized treatment decisions, and improved procedural planning for CAD management.

Guideline-Based Recommendations

Diagnosis

• Use CT for early detection of non-obstructive and obstructive CAD in patients with stable chest pain.
• Employ CT as a first-line diagnostic tool to reduce need for invasive coronary angiography.

Management

• Increase preventive therapy (aspirin, statins) based on CT detection of coronary atherosclerosis.
• Use CT findings to guide individualized decisions on revascularisation and additional functional testing.
• Plan revascularisation strategy (percutaneous or surgical) using CT-derived quantitative coronary imaging biomarkers.

Monitoring & Follow-up

• Monitor statin adherence and cholesterol reduction in patients diagnosed by CT to improve long-term outcomes.
• Use CT to reassess coronary anatomy and guide ongoing management decisions.

Risks

• CT reduces procedure-related complications compared to invasive coronary angiography.
• Current evidence limited in acute presentations and outside stable chest pain with intermediate CAD likelihood.

Patient & Prescribing Data

Stable chest pain patients with intermediate likelihood of CAD

CT-guided management increases aspirin and statin use and adherence, resulting in significant reduction in CAD mortality and myocardial infarction.

Clinical Best Practices

• Integrate CT early in diagnostic pathways for stable chest pain to detect non-obstructive CAD and initiate preventive therapy.
• Use CT findings to tailor further functional testing and revascularisation decisions individually.
• Leverage multidisciplinary collaboration to optimize CT image acquisition, interpretation, and clinical integration.
• Consider CT for procedural planning in patients with confirmed obstructive CAD to guide revascularisation approach.
• Recognize current limitations of CT in acute CAD presentations and the need for further research on AI applications.
