Cardiac computed tomography in asymptomatic siblings of patients with premature coronary disease: illustrations and...

Area of Science:

• Cardiology
• Preventive Medicine
• Medical Imaging

Background:

• Early-onset coronary artery disease (CAD) in a family member signals increased risk for siblings.
• Standard cardiovascular risk scores may underestimate risk in individuals with a strong family history of premature CAD.
• Subclinical atherosclerosis detection is crucial for preventive cardiology in high-risk families.

Purpose of the Study:

• To investigate the role of cardiac computed tomography (CT) in assessing coronary atherosclerosis in apparently healthy siblings of patients with early-onset CAD.
• To evaluate the potential of cardiac CT for reclassifying cardiac risk in middle-aged adults with a familial predisposition to CAD.
• To highlight the prevalence and prognostic value of CAD detection using cardiac CT in this susceptible population.

Main Methods:

• Case report of cardiac CT findings in three individuals from families with early-onset CAD.
• Review of current literature on cardiac CT for coronary atherosclerosis detection.
• Discussion of the utility of non-invasive imaging in managing familial cardiac risk.

Main Results:

• Cardiac CT identified coronary atherosclerosis in individuals without apparent cardiovascular disease from high-risk families.
• The study underscores the potential for cardiac CT to detect subclinical disease.
• Findings suggest standard risk assessment may be insufficient for this population.

Conclusions:

• Cardiac computed tomography (CT) shows promise for detecting coronary artery disease (CAD) in asymptomatic relatives of individuals with early-onset CAD.
• This imaging modality may aid in reclassifying cardiac risk and guiding preventive strategies.
• Increased awareness and utilization of cardiac CT are recommended for managing middle-aged adults at high familial risk for CAD.
