Troponin to Risk Stratify Patients for Computed Tomography Coronary Angiography — PRECISE-CTCA  

Coronary Artery Disease Clinical Trial

Official title:
Troponin Within the Normal Reference Range to Risk Stratify Patients With Acute Chest Pain for Computed Tomography Coronary Angiography

Clinical Trial Summary

Most patients presenting to hospital with chest pain are discharged home without further tests once a heart attack has been ruled out. Current strategies to assess patients with a suspected heart attack involve blood tests to measure troponin, a protein released into the bloodstream when the heart muscle is damaged. Despite having had a heart attack ruled-out, some patients have unrecognised coronary heart disease and are at risk of having a heart attack in the future. However, we do not know what is the best approach to identify and treat these patients. This study will use a heart scan known as computed tomography coronary angiogram (CTCA) to look for underlying coronary heart disease in patients who have had a heart attack ruled out. In an earlier study, we performed this scan in patients referred to the outpatient cardiology clinic with stable chest pain and found that this improved the diagnosis of coronary heart disease, leading to improvement in patient care that prevented many future heart attacks. Our research has also demonstrated that troponin levels below the threshold used to diagnose a heart attack identify those who are at greater risk of having a heart attack in the future. The aim of this study is to confirm whether these low levels of troponin can identify patients who have underlying coronary heart disease and may benefit from further testing and preventative treatment.

Clinical Trial Description

Using a newer, more sensitive troponin test, we now know that troponin levels even below the threshold used to diagnose a heart attack identify patients who are at risk of having a heart attack in the future. Our research in patients with stable chest pain demonstrated that computed tomography coronary angiogram (CTCA) improved the diagnosis of coronary heart disease, leading to improvement in patient care that prevented many future heart attacks. This study will build on these two major strands of research to confirm whether these low levels of troponin can identify patients who have underlying coronary heart disease and may benefit from further testing and preventative treatment. The investigators will evaluate consecutive patients presenting to hospital with suspected acute coronary syndrome and cardiac troponin concentration within the normal reference range for the presence of underlying coronary artery disease. All participants will be invited for an outpatient CTCA. Findings from this study will help inform a randomised controlled trial to evaluate the role of CTCA in patients who have a heart attack ruled out, but are identified as intermediate risk on troponin testing. ;
