Background
Rapid Access Chest Pain clinics (RACPCs) were established in the UK in 2000 following the publication of the National Service Framework for Coronary Heart Disease. Patients underwent an exercise test (ETT) in the clinic as part of a ‘one-stop’ protocol with follow-up only if further investigation was required. In 2010, the National Institute for Health and Care Excellence (NICE) produced guidelines for the assessment and diagnosis of chest pain of recent onset (CG95), replacing the recommendation for ETT with non-invasive functional testing for patients with an intermediate pre-test probability of coronary artery disease (CAD), necessitating multiple appointments to evaluate the patient’s symptoms. The guidelines were updated in 2016, with a new recommendation that patients with atypical or typical chest pain should undergo CT coronary angiography (CTCA) as the first diagnostic test.
Purpose
The aim of this study was to investigate the feasibility and potential benefit of performing same -day CTCA in the RACPC.
Method
From November 2016 all patients with atypical or typical chest pain attending the RACPC at this tertiary cardiac centre were referred for CTCA unless alternative investigation was clinically indicated. From February 2018, same day CTCA was offered to some patients. Up to two scans could be performed in each clinic, which was increased to up to three in June 2018.
Results
A total of 985 patients were seen in the nurse-led clinic between 12/02/2018 and 30/11/2019. 473 patients were referred for CTCA (48.0%) and 314 scans were carried out in the clinic (66.4%). Of those scans carried out in clinic, 128 patients had a CTCA which showed no evidence of CAD (40.8%) and 34.4% of scans showed non-obstructive CAD. In 18.2% of patients, the CTCA showed significant CAD and in 21 patients (6.7%) the scan was inconclusive. Patient with inconclusive scans underwent further testing which was negative in all cases. The outcome for patients with significant CAD (57 patients) is shown in the table.
Conclusion
CTCA on the same day as the RACPC appointment is feasible and facilitates rapid further investigation and treatment of patients with potentially significant CAD. It also enables patients with non-significant or no CAD to be reassured that their symptoms are unlikely to be cardiac which will reduce anxiety and allow timely investigation of other causes of the chest pain. Nurses need training in the risks of radiation in order to be able to request the scans and enable the clinic to be nurse-led.
