Insights

Screening asymptomatic individuals for coronary artery disease (CAD) is crucial for preventive treatment. Coronary artery calcium scoring shows the most promise for identifying intermediate-risk individuals.

Area of Science:

  • Cardiology
  • Preventive Medicine
  • Biomarkers and Imaging

Background:

  • Cardiovascular disease remains the leading global cause of mortality, with coronary artery disease as the primary contributor.
  • Preventive strategies for asymptomatic individuals are of significant clinical interest.

Purpose of the Study:

  • To evaluate the added value of novel biomarkers and imaging techniques for screening asymptomatic individuals for coronary artery disease.
  • To identify the most effective methods for risk stratification in intermediate-risk populations.

Main Methods:

  • Review of established risk scores (e.g., Framingham, SCORE) and emerging diagnostic tools.
  • Assessment of biomarkers including high-sensitivity C-reactive protein and phospholipase A2 variants.
  • Evaluation of imaging modalities such as coronary artery calcium score, carotid intima-media thickness, and ankle-brachial index.

Main Results:

  • The added value of new biomarkers and imaging methods over traditional risk scores varies.
  • Coronary artery calcium scoring demonstrates the most convincing evidence for improving risk assessment.
  • This method is particularly beneficial for asymptomatic individuals classified as intermediate-risk.

Conclusions:

  • Coronary artery calcium scoring is a valuable tool for refining risk assessment in asymptomatic individuals.
  • It aids in identifying those who may benefit from early preventive interventions for coronary artery disease.
  • Further research may elucidate the roles of other emerging markers in cardiovascular risk stratification.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
