Stages of atherosclerotic plaque development and unstable plaque types: pathophysiologic and histologic characteristics

Abstract: Российский кардиологический журнал № 5 (103) | 2013Согласно данным многих исследований, в основе развития атеросклероза лежит последовательное взаи-модействие многих этиопатогенетических факторов, ведущее, в конечном счете, к образованию атеросклеро-тической бляшки [1][2][3].Начальная стадия атеросклероза характеризуется появлением в интиме артерий пятен и полосок, содер-жащих липиды. Липидные пятна появляются в арте-риях с раннего детства. В возрасте 10 лет липидные пятна занимают около 10% интимы аорты, а к … Show more

“…Plaque evolution begins with the stage of “fatty streaks”, which are formed already in childhood and adolescence due to the accumulation of low- and very-low-density lipoproteins, their binding to proteoglycans in the intima, and the development of an inflammatory reaction leading to endotheliocyte activation. In the early stages, an increase in endotheliocyte permeability to low-density lipoproteins rich in cholesterol is observed, as well as an increase in the adhesive properties of the endothelial surface, which promotes monocyte migration from the vascular lumen to the subendothelial space [ 9 ]. The driver of increasing the adhesive properties of the endothelium is the adhesion molecules expressed on the cell surface, among which VCAM-1 and ICAM-1 (from the immunoglobulin superfamily) and P-selectins play a special role [ 10 ].…”

“…Muller et al in 1989 to designate atherosclerotic plaques that do not affect hemodynamics, but at the same time are dangerous from the point of view of thrombosis [8]. Histopathologically vulnerable plaques are usually described as thin-capsule fibroatheromas [9]. The concept of unstable plaque is more often used for symptomatic plaques that have realized their potential by giving rise to a vascular event (ischemic stroke, acute coronary syndrome, etc.).…”

“…В частности, разрыв бляшек в ЭКА приводит к острому несоответствию объема кровоснабжения головного мозга его потребности в кислороде (острое нарушение мозгового кровообращения (ОНМК) по ишемическому типу), в то время как постоянное стабильное стенозирование просвета ЭКА клинически проявляется хронической ишемией головного мозга (ХИГМ). Таким образом, клинически бляшки можно подразделить на нестабильные (вызвавшие ОНМК) и стабильные (характеризующиеся постепенным развитием ХИГМ) [2]. Несмотря на принципиальные отличия клинического фенотипа стабильного и нестабильного атеросклероза ЭКА, патофизиологические факторы нестабильности атеросклеротических бляшек (АСБ) и особенно механизмы их регуляции остаются в значительной степени неизвестными.…”
