Abstract

Objective
Coronary computed tomographic angiography (CCTA) is a modality used to aid in the diagnosis of patients suspected of having coronary artery disease (CAD). This study describes patients with chronic coronary syndrome in whom CCTA evaluations were indicated at the Siloam Diagram Heart Hospital.
Materials and Methods
This study is descriptive research that was conducted at Siloam Diagram Heart Hospital between January 2021 and December 2022. The samples were taken from patients who were diagnosed with chronic coronary syndrome and indicated to have CCTA examinations. The obtained data include the computed tomography calcium score (CAC), Coronary Artery Disease Reporting and Data System 2.0 (CAD-RADS) categorization, and the individual results for each coronary artery. Data collection, compilation, and processing occurred between June 2023 and December 2023.
Results
CCTA was performed on 593 outpatients with suspected CAD in Siloam Diagram Heart Hospital, Indonesia. The average patient age was 51 years old. The ratio of male patients to female patients was 1.3:1. Nine patients had a history of stenting. A total of 286 (48.2%) patients had CAC=0 (very low risk of CAD), while 60 (10.1%) patients had CAC ≥300 (moderate-severely increased risk). Three hundred twenty-two (54.3%) patients were categorized as CAD-RADS 0, while 4 (0.7%) patients were on CAD-RADS 5. The most common stenosis occurred in the left anterior descending (LAD), which was identified in 250 (42.2%) patients, and 163 (27.5%) patients were also found to have myocardial bridging in the LAD. The most frequently affected area is the proximal part of the LAD.
Conclusion
CCTA is very useful for assessing the anatomical condition of the coronary blood vessels. Using the results of a CCTA examination, physicians can assess a patient’s prognosis as well as determine the appropriate therapy. CAD-RADS is another tool that can be used to help determine optimal therapies, but it should still be based on the clinical findings.
