TOHETI aims to improve the management of patients that attend A&E with an episode of acute chest pain, where a heart attack is ruled out through initial tests including heart trace electrocardiograph (ECG) and blood tests including troponin.
Upon discharge, sometimes concerns remain high regarding the possibility of significant underlying coronary artery disease (narrowing(s) of the heart blood vessels) and resulting risk of a potential future heart attack. Currently these patients who have been discharged from A&E are referred to their GP to be subsequently referred onwards to a cardiology clinic, if deemed appropriate.
A new Hot Chest Pain Clinic is being established at Guy’s and St Thomas’, where patients can be directly referred to from A&E, depending on concerns regarding the risk of the presence of significant underlying coronary artery disease.
TOHETI aims to evaluate whether the use of the non-invasive imaging techniques of Computed Tomography Coronary Angiography (CTCA) and Cardiac Magnetic Resonance (CMR), in patients referred to the Hot Chest Pain Clinic contributes to a quicker and more efficient diagnosis in ruling in or ruling out Coronary Artery Disease.
