A Review of a Tertiary Referral Centre's CT Coronary Angiography Programme.

Aims To investigate the implication of outpatient CT coronary angiogram (CTCA) waiting times on patient outcomes and service provision. Methods All outpatient CTCAs requested for stable chest pain during 2017 in our catchment area were included. Rate of major adverse cardiovascular events (MACE), presentations with chest pain to the emergency department (ED), cardiology outpatient attendance, time interval in alteration of Coronary artery disease (CAD) prognostic treatment, rate of angiography and percutaneous coronary intervention (PCI) were noted. Results 172 CTCAs were included. 11 (6.4%) presented to ED with chest pain. 38 (22.1%) attended outpatients prior to scan completion. 17 (9.9%) required alteration of prognostic treatment, taking on average 10.4 (+/-4.5) months to occur. 21 (12.2%) underwent coronary angiography and 7 (4.1%) had PCI, which took on average 9.9 (+/-6.6) months. One non-fatal MI requiring CABG was noted. Conclusion The low rate of MACE and revascularisation likely represents appropriately low risk patient selection for CTCA. Presentation to clinic prior to scan completion highlights a need for better administration support.
