Cardiac Magnetic Resonance for Asymptomatic Type 2 Diabetics With Cardiovascular High Risk (CATCH) - Pilot Study — CATCH  

Coronary Artery Disease Clinical Trial

Official title:
Cardiac Magnetic Resonance for Asymptomatic Type 2 Diabetics With Cardiovascular High Risk (CATCH) - Pilot Study

Clinical Trial Summary

The aim of this study is to determine the prevalence of myocardial ischaemia in asymptomatic high risk type 2 diabetic patients using stress cardiac MR and how many stress cardiac MR examinations are false positive.

Clinical Trial Description

Asymptomatic coronary artery disease (CAD) is highly prevalent (ie. 17-59%) in type 2 diabetic patients. In addition, cardiovascular disease remains the most common cause of death in type 2 diabetics. Previous trials using coronary computed tomography angiograms (CCTA) or nuclear myocardial perfusion imaging (MPI) to screen for asymptomatic coronary artery disease requiring intervention have been unsuccessful at reducing cardiovascular and all cause mortality when compared to optimised medical therapy where cardiovascular risk factors are treated in order to reduce cardiovascular complications. Possible reasons for this include, the choice of imaging modality, the intervention chosen (eg. bare metal stents vs drug eluting stents), patient cohort (eg. all diabetics vs high risk diabetics). Stress cardiac magnetic resonance (CMR) is ideally suited to assess this group of high risk patients as there is no radiation exposure and it allows a more complete analysis of the heart including the assessment of myocardial viability, cardiac systolic and diastolic function. The significance of this envisioned randomised controlled trial is firstly to investigate if stress CMR screening will reduce major adverse cardiovascular events including death. Secondly, a study using stress CMR has never been performed. ;
