Цель: проанализировать литературные данные о роли адипонектина, Р-селектина и интегрина β3 в патогенезе развития рестеноза внутри стента у пациентов с ишемической болезнью сердца после коронарного стентирования, а также возможности использования перечисленных биомаркеров в качестве предикторов рестенозирования. Результаты. Были рассмотрены некоторые аспекты патогенеза развития рестеноза внутри стента у пациентов с ишемической болезнью сердца после коронарного стентирования, в том числе роль адипонектина, Р-селектина и интегрина β3, а также их прогностическое значение. Выводы. Приведенные данные свидетельствуют о возможной роли адипонектина, Р-селектина и интегрина β3 в патогенезе развития рестеноза внутри стента у пациентов с ишемической болезнью сердца после коронарного стентирования. Однако результаты выполненных исследований, в которых оценивалось прогностическое значение перечисленных биомаркеров в аспекте развития рестеноза внутри стента, носят противоречивый характер.
At present, there are a number of problems associated with the diagnosis of restrictive type of ventilation disorders: first, to identify restriction, it is necessary to perform body plethysmography, which is a laborious technique and requires the active cooperation of the patient with medical personnel; secondly, methodological issues that concern the criteria for the diagnosis of restriction are still under development. Impulse oscillometry (IOS) is a non-invasive and effortless technique for the patient to identify ventilation disorders, especially obstructive ones. In order to assess the informative value of IOS in the diagnosis of the restrictive ventilation disorders, respiratory impedance and its parameters were measured in 82 patients with various bronchopulmonary pathologies. The restriction was established on the basis of spirometric and bodyplethysmography studies. The results showed that IOS is a low-sensitivity method for detecting the restrictive type of ventilation disorders with mild reduced total lung capacity (TLC≥70%pred.), since in this case, the basic parameters of the IOS, such as the resistive component of the respiratory impedance (Rrs) at 5 and 20 Hz (Rrs5 and Rrs20, respectively), as well as the reactive component of the respiratory impedance at 5 Hz (Xrs5) remain within the normal values. When TLC was less than 70%pred., there was a decrease of Xrs5 with an increase in the resonance frequency and the preservation of the normal values of Rrs5 and Rrs20. The abnormal absolute frequency dependence of Rrs was determined at any degree of change in the TLC, increasing as it decreased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
