Cardiac CT angiography in current practice: An American society for preventive cardiology clinical practice...

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Coronary artery disease (CAD) remains a leading cause of mortality worldwide.
• Non-invasive diagnostic modalities are crucial for early detection and management of CAD.
• Cardiac computed tomography (CT) is an evolving imaging technique with growing applications in cardiovascular health.

Purpose of the Study:

• To summarize current evidence and clinical applications of cardiac CT for CAD evaluation.
• To appraise the established and emerging indications for cardiac CT in clinical practice.
• To provide an expert consensus on the role of cardiac CT in cardiovascular prevention.

Main Methods:

• Expert panel review of current evidence and clinical practice guidelines.
• Synthesis of data on the diagnostic and prognostic utility of cardiac CT.
• Exploration of emerging applications such as CT-derived fractional flow reserve, peri-coronary inflammation, and AI.

Main Results:

• Cardiac CT, particularly coronary CT angiography (CCTA), is a frontline non-invasive test for CAD.
• CCTA excels in identifying and characterizing stenosis severity and atherosclerotic changes.
• Evidence supports CCTA's utility in both diagnosis and prevention of CAD.

Conclusions:

• Cardiac CT is an essential tool for cardiovascular prevention, risk assessment, and early management of CAD.
• Emerging applications like functional assessment and AI promise personalized risk stratification and treatment.
• Further research is needed to fully explore the potential of advanced cardiac CT techniques.
