Non-invasive and Invasive Plaque Characterisation

September 10, 2014 updated by: Gabija Pundziute, University Medical Center Groningen

Coronary Artery Plaque Characterisation With Non-invasive Multi-Slice Computed Tomography and Invasive Intravascular Ultrasound and Optical Coherence Tomography in Patients With Acute Coronary Syndromes Without ST-segment Elevation

The accuracy of coronary plaque characterization with Multi-slice computed tomography as compared to intravascular ultrasound and optical coherence tomography will be investigated in patients presenting with acute coronary syndrome without ST-elevation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Accuracy of detection of thrombus with MSCT as compared to IVUS and OCT will be investigated.
Time Frame: 24 hours
All imaging methods will be performed in each patient. A 24 hour period is the maximum allowed time gap between MSCT and invasive imaging (OCT/IVUS).
24 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Accuracy of atherosclerotic plaque characterisation with MSCT as compared to IVUS and OCT will be investigated.
Time Frame: 24 hours
A maximum interval of 24 hours between MSCT and IVUS/OCT is allowed in this study.
