Brief Summary: Acute myocardial infarction owes to a plaque rupture resulting in total STEMI or partial occlusion NSTEMI of the coronary artery In patients with a partial occlusion and multi vessel disease MVD identification of the lesion responsible for the current event culprit at the time of the examination coronary angiogram CAG can be difficult

Meanwhile identification of the culprit lesion is vital to conduct proper treatment Furthermore treating an artery with no plaque rupture non-culprit imposes a small risk for complications which may be fatal Precise identification of the culprit lesion in NSTEMI patients with MVD remains unsettled

The purpose of this study is proper and precise identification of the culprit lesion in NSTEMI patients with MVD
Detailed Description: Background

Acute myocardial infarction owes to a plaque rupture resulting in total STEMI or partial occlusion NSTEMI of the coronary artery Current guidelines in NSTEMI recommend an invasive coronary angiogram CAG and possible treatment with percutaneous intervention PCI within 2-72 hours In NSTEMI patients and multi vessel disease MVD identification of the lesion responsible for the current event culprit at the time of the examination can be difficult

Meanwhile identification of the culprit lesion is vital to conduct proper treatment in order to restore blood flow to the myocardium Furthermore treating an artery with no plaque rupture non-culprit imposes a small risk for complications which may be fatal In addition since the symptoms relate to the culprit lesion it is currently unclear whether all stenosis or only the culprit should be treated by PCI Today precise identification of the culprit lesion in NSTEMI patients with MVD remains unsettled

Purpose

The overall objective of this study is proper and precise identification of the culprit lesion in NSTEMI patients with MVD

Methods

The study employs cardiac magnetic resonance CMR which allows detection of myocardium exposed to even brief periods of ischemia Furthermore Optical Coherence Tomography OCT which visualises the coronary artery lumen and wall OCT allows for direct visualization of atherosclerotic plaques presence of thrombus and atherosclerotic plaque ruptured that cannot be seen on a CAG alone

Patients will have CMR performed prior to CAG The PCI operator determines culprit based on CAG and ECG changes alone OCT is subsequently performed on culprit lesions and stenosis 50

Sample size calculation

Assuming the culprit lesion can be correctly identified with historyangiographyECG in 95 of cases a positive predictive value 90 with 95 accuracy can be reached with 100 patients
