Key result
OCT detects plaque rupture in 73% of acute MI cases, outperforming angioscopy and IVUS.
Why the study?
Optical coherence tomography is a high-resolution intravascular imaging method that may allow detailed in vivo assessment of vulnerable plaques, prompting evaluation of its ability to assess culprit lesion morphology in acute myocardial infarction compared with IVUS and CAS.
Does optical coherence tomography (OCT) improve the detection of culprit lesion morphology in patients with acute myocardial infarction compared to intravascular ultrasound (IVUS) and coronary angioscopy (CAS)?

OCT may better characterize vulnerable plaques in AMI but should not yet change practice; leaves open incremental value versus IVUS and CAS.

OCT provides superior in vivo detection of vulnerable plaque morphologies, such as plaque rupture and fibrous cap erosion, in patients with acute myocardial infarction compared to IVUS and CAS.
Kubo et al. (2007) conducted an observational in Acute Myocardial Infarction (n=30). Optical coherence tomography (OCT) vs. Intravascular ultrasound (IVUS) and coronary angioscopy (CAS) was evaluated on Detection of plaque rupture (p=0.009). Optical coherence tomography detected plaque rupture in acute myocardial infarction more frequently (73%) than coronary angioscopy (47%, p=0.035) and intravascular ultrasound (40%, p=0.009).
