Purpose
Myocardial infarction and sudden cardiac dearth are the first manifestation of coronary atherosclerosis in 50% of men and 64% of women in the world [].
The common reason of acute coronary events is intracoronary thrombosis [].
However the mechanism of thrombosis may be different and depend on the structure of coronary plaques.
According to plaque classification (AHA) thin-cap fibroatheroma (TCFA) is the type of plaques that is prone to rupture.
These plaques are commonly called vulnerable plaques.
Some invasive methods (intravascular ultrasound - IVUS,
optical coherence tomography – OCT) and one non-invasive method (CT-coronary angiography,
CTCA) are applied for coronary plaque visualization in clinical practice.
CTCA has good perspectives as the screening method for detection of vulnerable coronary plaques before the onset or the hospitalization.
The purpose of the study was to evaluate CT-features of coronary plaques (symptom-related,
SRP,
and symptom-nonrelated plaques,
SNP) that are detected with IVUS in gray scale and IVUS with spectral analysis (color-code map) in patients with acute coronary syndrome (ACS).
