Coronary Computed Tomography Angiography in Suspected Coronary Artery Disease: A Rapidly Developing Noninvasive Study

Background: The death rate of people in developing countries keeps on increasing, which is due to coronary artery disease (CAD).Coronary computed tomography angiography (CCTA) has improved as a valuable noninvasive diagnostic imaging test to evaluate and manage patients with clinical suspicion of CAD.Aim and objective: This study aims to describe the rapidly developing noninvasive CCTA-based diagnostic imaging test for patients with clinical suspicion of CAD. Materials and methods: We had included 50 patients for this study; patients presenting with signs and symptoms of CAD who were referred for CCTA were included.The patient's blood urea and serum creatinine values were checked before undergoing CCTA.The contrast media used for the study was iohexol (Omnipaque 350 mg/mL).After giving the beta-blockers, the computed tomography (CT) coronary angiogram was done using GE healthcare Optima 660-128 slice CT scanner.Result: Our present study shows 64% (32 out of 50 patients) were diagnosed as normal, 18% (9 out of 50 patients) were diagnosed as low risk, 12% (6 out of 50 patients) were diagnosed as intermediate -risk, and 6% (3 out of 50 patients) were diagnosed as high-risk group based on CAD reporting and data system (CAD-RADS) score.Conclusion: Based on our observations, we have summarized that the CCTA is a noninvasive imaging technique that is clinically useful, cost-effective, and for outpatient investigation.
