Insights
Coronary artery calcium scoring and coronary computed tomography offer improved diagnosis for acute chest pain patients, potentially reducing hospitalizations. Evidence and applications are reviewed, considering cost and radiation exposure.
Area of Science:
- Cardiology
- Medical Imaging
- Emergency Medicine
Background:
- Acute chest pain evaluation is challenging due to limitations of traditional diagnostic methods.
- Non-invasive imaging technologies show promise for improving diagnostic efficiency and patient outcomes.
- Controversy exists regarding the evidence base for newer imaging technologies.
Purpose of the Study:
- To review the role of coronary artery calcium score and coronary computed tomography (CCT).
- To assess their usefulness in evaluating individual coronary risk and guiding emergency department disposition.
- To describe evidence, clinical applications, cost-effectiveness, and radiation exposure.
Main Methods:
- Review of existing evidence on coronary artery calcium scoring.
- Review of existing evidence on coronary computed tomography (CCT).
- Analysis of clinical applications, cost-effectiveness, and radiation exposure.
Main Results:
- Coronary artery calcium scoring aids in assessing individual coronary risk.
- Coronary computed tomography (CCT) can facilitate appropriate emergency department disposition decisions.
- Evidence supports the use of these non-invasive techniques, but further research may be needed.
Conclusions:
- Coronary artery calcium score and CCT are valuable tools for acute chest pain assessment.
- These imaging modalities can improve diagnostic efficiency and reduce unnecessary hospitalizations.
- Consideration of cost-effectiveness and radiation exposure is crucial for implementation.
Abstract:
Accurate and efficient evaluation of acute chest pain remains clinically challenging because traditional diagnostic modalities have many limitations. Recent improvement in non-invasive imaging technologies could potentially improve both diagnostic efficiency and clinical outcomes of patients with acute chest pain while reducing unnecessary hospitalizations. However, there is still controversy regarding much of the evidence for these technologies. This article reviews the role of coronary artery calcium score and the coronary computed tomography in the assessment of individual coronary risk and their usefulness in the emergency department in facilitating appropriate disposition decisions. The evidence base and clinical applications for both techniques are also described, together with cost- effectiveness and radiation exposure considerations.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
