[Non-obstructive coronary artery disease documented by cardiac computed tomography: Discrepancy between...

Area of Science:

• Cardiology
• Radiology
• Preventive Medicine

Background:

• Cardiac computed tomography (CT) is effective in identifying coronary artery disease (CAD).
• The prognostic significance of non-obstructive CAD detected by cardiac CT is established.
• Current guidelines lack clarity on managing patients with non-obstructive CAD, particularly regarding primary prevention pharmacological interventions.

Observation:

• The case study highlights a discrepancy between estimated cardiovascular risk and actual atherosclerotic burden.
• A competitive athlete with a high calcium score (above 90th percentile) and non-obstructive CAD presented with a very low estimated cardiovascular risk.
• This patient was asymptomatic and lacked traditional cardiovascular risk factors or history.

Findings:

• The study emphasizes the challenge in deciding on pharmacological primary prevention for individuals with unexpected atherosclerotic burden.
• Discrepancies between risk scores and cardiac CT findings complicate clinical decision-making.
• Non-obstructive coronary artery disease on cardiac CT necessitates careful consideration in risk stratification.

Implications:

• This case underscores the need for refined guidelines in managing non-obstructive coronary artery disease.
• Further research is required to balance the benefits and risks of primary prevention in such cases.
• Integrating cardiac CT findings into risk assessment models may improve patient management strategies.
