[Comparison of Atherosclerotic Lesions in Patients With Acute Myocardial Infarction and Stable Angina Pectoris Using Intravascular Ultrasound].

Aim: to compare noninfarct-related lesions in patients with acute myocardial infarction (MI) with culprit and non-culprit lesions in patients with stable angina pectoris (SAP) using intravascular ultrasound virtual histology (VH-IVUS).

Material And Methods: Overall 70 patients were enrolled: 38 with ST elevation (STE) MI and 32 with stable angina pectoris (SAP). All patients underwent three-vessel coronary angiography and gray-scale and VH-IVUS after percutaneous coronary intervention (PCI) of infarct-related lesion in STEMI or culprit lesion in SAP.

[Noninvasive Methods of Detection of Vulnerable Atherosclerotic Plaques in Coronary Arteries].

In most cases direct cause of acute coronary syndrome and sudden death is an intracoronary thrombus formed on a surface of unstable atherosclerotic plaque (UAP). The following are main characteristics of UAP: active inflammation; large lipid rich nucleus occupying a40% of plaque volume; thin (< 65 mm) fibrous cap; erosions of intima over plaque; tear of plaque cap; superficially located calcium nodules; intraplaque hemorrhage. Visualization of UAP in coronary arteries is a very important direction in diagnostics.
