Insights

Coronary atherosclerosis primary prevention uses cardiac computed tomography (CT) to identify risk. Coronary CT angiography (CCTA) and coronary artery calcium (CAC) scoring are key tools for early detection and guiding therapy.

Area of Science:

  • Cardiology
  • Radiology
  • Preventive Medicine

Background:

  • Primary prevention of coronary atherosclerosis aims to prevent sudden cardiac death and myocardial infarction.
  • Accurate identification, effective therapy, and monitoring of at-risk individuals are crucial for successful prevention.
  • Cardiac computed tomography (CT) offers methods for identifying and monitoring atherosclerosis burden.

Purpose of the Study:

  • To explore the role of coronary CT angiography (CCTA) and coronary artery calcium (CAC) scoring in subclinical atherosclerosis.
  • To review the use of CCTA and CAC scoring in screening and guiding primary prevention strategies.
  • To examine therapeutic trials investigating plaque-modifying therapies guided by CCTA.

Main Methods:

  • Utilizing cardiac CT to determine coronary artery calcification (CAC) as a surrogate for atherosclerosis burden.
  • Employing coronary CT angiography (CCTA) to identify arterial lumen narrowing and mural atherosclerosis.
  • Analyzing data from screening studies and therapeutic trials that used CCTA for primary prevention guidance.

Main Results:

  • Cardiac CT, specifically CAC scoring and CCTA, can identify subclinical coronary atherosclerosis.
  • CCTA highlights arterial lumen narrowing and mural plaque not visible through other anatomical methods.
  • Evidence suggests CCTA's utility in guiding primary prevention strategies and assessing plaque-modifying therapies.

Conclusions:

  • Coronary CT angiography (CCTA) is essential for detecting and managing clinical coronary artery disease.
  • While its role in subclinical atherosclerosis is evolving, CCTA is poised to become more prominent in primary prevention.
  • Modern CT technology and pharmacotherapy advancements will likely enhance CCTA's contribution to preventing coronary atherosclerosis.

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

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...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
