Insights
Coronary CT angiography (CCTA) is a reliable, noninvasive tool for detecting coronary artery disease (CAD). This study shows CCTA has high accuracy in identifying coronary stenosis, making it valuable for early diagnosis.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Coronary artery disease (CAD) is a leading cause of mortality globally and in India.
- Conventional catheter examinations are invasive and primarily diagnostic.
- A noninvasive, reliable method for early CAD detection and coronary artery imaging is needed.
Purpose of the Study:
- To evaluate the effectiveness of coronary CT angiography (CCTA) for diagnosing coronary artery disease.
- To compare CCTA findings with conventional coronary angiography.
- To assess the diagnostic accuracy of CCTA in symptomatic patients.
Main Methods:
- 101 symptomatic patients advised for coronary CT angiography (CCTA) were included.
- Coronary vessel patency was assessed using both CCTA and conventional coronary angiography.
- Data analysis focused on lesion detection and diagnostic performance metrics.
Main Results:
- The study included 101 symptomatic patients.
- CCTA identified 124 lesions, with 101 deemed serious, predominantly in the left anterior descending artery.
- CCTA demonstrated high diagnostic accuracy: 98.4% sensitivity, 91.7% specificity, 95% positive predictive value, and 97.05% negative predictive value.
Conclusions:
- Coronary CT angiography (CCTA) is a highly accurate noninvasive method for evaluating coronary artery disease.
- CCTA exhibits excellent negative predictive value for detecting coronary stenosis.
- The findings support CCTA as a trustworthy technique for early CAD diagnosis and imaging.
Introduction:
One of the main causes of illness and death in both India and globally is coronary artery disease, or CAD. Previously, the majority of conventional catheter examinations were performed simply for diagnostic purposes. So, a noninvasive and trustworthy method was highly desirable for early CAD detection and coronary artery imaging.
Material And Methods:
Symptomatic patients attending the routine cardiac outpatient department at RIMS, Ranchi, who were advised to undergo coronary CT angiography (CCTA) for further evaluation in the Department of Radiodiagnosis were included.
Results:
A total of 101 symptomatic patients were studied for patency of coronary vessels in both CCTA and conventional coronary angiography. Based on the CCTA of the 101 patients, majority of the patients belong to single vessel disease. CCTA revealed 124 lesions, of which 101 were considered serious with a majority of lesions in the left anterior descending. The sensitivity, specificity, positive predictive value, and negative predictive value of the multidetector computed tomography were 98.4, 91.7, 95, and 97.05%.
Conclusion:
CCTA is a good negative predictive value technique for coronary stenosis and is relatively trustworthy.

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...
