Key result
Intravascular imaging reduces ACS mortality by aiding the detection of atherosclerotic mechanisms.
Why the study?
Intravascular imaging plays crucial roles in reducing ACS mortality, identifying atherosclerotic and nonatherosclerotic mechanisms, and optimizing PCI, prompting a review of its clinical and prognostic roles, guideline recommendations, and a comparison between IVUS and OCT.
What is the role of intravascular imaging (IVUS and OCT) in identifying mechanisms, optimizing PCI, and improving outcomes in patients with acute coronary syndrome?
What is the role of intravascular imaging (IVUS and OCT) in identifying mechanisms, optimizing PCI, and improving outcomes in patients with acute coronary syndrome?
This review highlights the critical role of intravascular imaging (IVUS and OCT) in understanding ACS pathophysiology and optimizing PCI to improve patient outcomes.
Supports intravascular imaging in ACS per consensus; leaves open definitive outcome benefits pending higher-level evidence.
Acute coronary syndrome (ACS) represents the most severe manifestation of coronary artery disease. Intravascular imaging, both intravascular ultrasound (IVUS) and optical coherence tomography (OCT), have played crucial roles for the impressive reduction in mortality of ACS. Intravascular imaging is useful for the detection of atherosclerotic mechanism (plaque rupture, calcified nodules, or plaque erosions) and for the evaluation of nonatherosclerotic and nonobstructive types of ACS. In addition, IVUS and OCT play a crucial role in the optimization of the PCI. The aim of the current review is to present the role of intravascular imaging in identifying the mechanisms of ACS and its prognostic role in future events, to review the current guidelines suggesting intravascular imaging use in ACS, to summarize its role in PCI in patients with ACS, and to compare IVUS and OCT.
