In the clinical research organoprotective effect of ACE inhibitor was widely discussed, the ACE inhibitor being connected with the suppression of the activity of renin-angiotensin-aldosterone system and the sympathetic nervous system. This notwithstanding, there are no well-outlined information about regression of the earliest evidence for remodeling of heart and blood vessels on extracellular level against the background of antihypertensive therapy. To determine the relation between remodeling of myocardium and blood vessels in different variants of accompanying vegetative stress we have compared the morphometrical data in rats of Vistar line under the influence of chronic adrenergic and cholinergic stress with the effect of medicine from ACE inhibitor group - Enap. The results showed that the remodeling of left ventricular myocardium, aorta and femoral artery took place under the conditions of all variants of vegetative provision of chronic stress being compared with the control group. Protective effect of ACE inhibitors was not observed in aorta and femoral artery under different models of chronic stress; moreover, in cases of chronic stress Enap administration increased remodeling of extracellular space of femoral artery. In the left ventricular myocardium, the protective effect of Enap was observed on remodeling of extracellular space only in case of chronic adrenergic stress.</abstract><trans-abstract xml:lang="ru">Проведено сравнение данных морфометрии для определения взаимосвязи между ремоделированием миокарда и сосудов и различными вариантами вегетативного сопровождения стресса крыс-самцов линии Вистар при хроническом адренергическом и хроническом холинэргическом стрессе и под влиянием препарата из группы ингибиторов АПФ - энапа. Результаты показали, что ремоделирование миокарда ЛЖ, аорты и бедренной артерии с изменением объемной плотности внеклеточных пространств наблюдалось при всех вариантах вегетативного обеспечения хронического стресса по сравнению с контролем. В аорте и бедренной артерии при различных моделях хронического стресса не был выявлен протективный эффект ингибитора АПФ, более того, при хроническом ХС (холинэргический ситресс) введение энапа усиливало ремоделирование внеклеточных пространств бедренной артерии. В миокарде ЛЖ наблюдался протективный эффект энапа на ремоделирование ВКП только при хроническом АС (адренэргический стресс).</trans-abstract><kwd-group xml:lang="en"><kwd>remodeling</kwd><kwd>heart</kwd><kwd>blood vess</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ремоделирование</kwd><kwd>сердце</kwd><kwd>сосуды</kwd><kwd>внеклеточные пространства</kwd><kwd>стресс</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Grassi G.
