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.

Outcome Measures

Primary Outcomes (1)

  • Is the PCI operator capable of identifying the culprit lesion based on ECG-changes and CAG? (CMR is the golden standard)

    Correlation between operator identification of the culprit and CMR/OCT. The location of the culprit on CAG/ECG and OCT versus CMR will be evaluated by the chi2-test

    Through study completion, an average of 1 year

Secondary Outcomes (2)

  • Positive predictive value of PCI operator identification of culprit lesion with CAG and ECG.

    Through study completion, an average of 1 year

  • Improvement in identification of culprit lesions evaluated by identification of an additional diagnostic value of OCT compared to CAG/ECG

    Through study completion, an average of 1 year

Study Arms (1)

CMR and OCT in NSTEMI patients with MVD

NSTEMI patients with multi vessel disease

Diagnostic Test: CMR and OCT in NSTEMI patients with MVD

Interventions

Lesions \>50% stenosis i patients with NSTEMI are examined by OCT. All patients will have CMR performed prior to angiography

Sampling MethodNon-Probability Sample
Study Population

Eligible NSTEMI patients scheduled for CAG at one center

You may qualify if:

  • Patients \> 18 years of age
  • NSTEMI (ECG changes and/or troponin/creatine kinase myocardial band (CK-MB) rise) within 48 hours after symptom debut.
