Summary

This study aims to test the hypothesis that cardiogoniometry (CGM) is helpful to identify the site of the culprit vessel in patients with NSTEMI in comparison to 12-lead ECG.

NSTEMI constitutes a clinical syndrome subset of acute coronary syndrome which is most usually caused by atherosclerotic coronary artery disease. It is defined by "electrocardiographic (ECG) ST-segment depression or prominent T-wave inversion and/or positive biomarkers of necrosis (e.g., troponin) in the absence of ST-segment elevation and in an appropriate clinical setting (chest discomfort or angina equivalent)". The standard 12 lead ECG is not commonly sensitive at localising the site of the culprit lesion and even coronary angiography may not always be helpful as the majority of lesions will not have angiographically evident thrombus. Patients with an ACS may have multivessel disease and it is often not possible to identify the precise site of the culprit lesion. In patients with multivessel disease, interventionists will frequently target the most severe stenosis even though this is not necessarily the acute lesion.

CGM (Cardiogoniometry cardiologic explorer, Enverdis GmbH medical solutions, Germany) is a form of 3D vector electrocardiography which can provide quantitative analysis of myocardial depolarisation and repolarisation. It has CE mark and has been shown to be more sensitive and specific than standard 12-lead ECG at diagnosing stable coronary artery disease. Furthermore, recent work has shown CGM to be more sensitive at detecting patients with NSTEMI than conventional 12-lead ECG

In summary, there is evidence that CGM is more efficacious than 12-lead ECG at the diagnosis of both stable CAD and ACS. The hope is this that the clinical application can be extended to localising ischaemia in the culprit vessel and be a valuable diagnostic aid.

The primary objective of this study is to investigate the efficacy of CGM to identify the culprit vessel in patients presenting with NSTEMI. Secondary endpoint will be to evaluate the efficacy of CGM to detect a significant coronary stenosis (defined as ≥70%) as compared to a standard 12-lead ECG
