Eligibility
Inclusion criteria
Inclusion criteria: Stable admitted patients (intermediate or low risk) i.e exertional dyspnea or chest pain referred to the Department of Radiology by the cardiologist with the suspect of obstructive coronary artery disease and have undergone coronary angiography but not revascularization. Chronic total occlusion cases Multi-vessel/ single vessel disease cases( >50 % stenosis) No contraindication to contrast-enhanced MRI
Exclusion criteria
Exclusion criteria: Who have contraindications for adenosine i.e., second- or third-degree A-V block, sick sinus syndrome, known hypersensitivity to adenosine Patients at highest risk for CAD such as those with elevated cardiac enzymes or electrocardiographic ST-segment changes consistent with on-going infarction or ischemia
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Hypointensity if observed both during stress considered to be an artifact/infarct/ischaemia. Stress-induced hypo perfusion/ ischaemia is considered present if a focal region of myocardium showing diminished contrast enhancement is present during stress and not observed at rest or not showing late gadolinium enhancement. If it is showing late gadolinium enhancement it is considered to be an Infarct. Timepoint: immediately after the scan | — |
Secondary
| Measure | Time frame |
|---|---|
| Correlating the coronary artery distribution on coronary angiography with myocardial perfusion abnormality on MRI using cross-sectional AHA myocardial segments classification. Timepoint: 1 year | — |
