Abstract :

Background: There are few studies that compared CTCA in patients presenting with chest pain, probably ischaemic (i.e., atypical) with negative or inconclusive TMT in outpatient department. Objective: To assess 64–slice CTCA findings in patients with suspected ischaemic chest pain and negative or inconclusive TMT. Methodology: Enrolled patients underwent TMT and classified as TMT negative or inconclusive patients. These patients underwent CTCA and findings were analysed. Results: 50 patients completed the study protocol. Of these, 31 (62%) were TMT negative and 19 (38%) were TMT inconclusive. CTCA showed obstructive CAD in 19 (38%) patients; 7 (36%) with negative TMT and 12 (63%) with inconclusive TMT. Overall, CTCA was more predictive of diagnosing obstructive lesion in TMT inconclusive group as compared to TMT negative group. Conclusion: In patients with atypical chest pain with negative or non–diagnostic TMT, CTCA provides an important diagnostic tool for rapid triaging of such patients.
