Развитие артериальной гипертензии (АГ) сопряжено с нарушениями кожной микроциркуляции крови. Лазерная допплеровская флоуметрия — объективный, количественный, инструментальный метод, позволяющий проводить оценку кожной микроциркуляции крови. Однако метод не нашел широкого клинического применения из-за высокой вариабельности показателей перфузии и небольшой величины различий этого показателя у здоровых людей и пациентов с АГ и, как следствие, низкой диагностической значимости.</p><p>Цель исследования — обосновать подходы, позволяющие повысить информативность изучения кожной микроциркуляции методом лазерной допплеровской флоуметрии у пациентов с АГ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование было проведено на пациентах с АГ (n = 13, медиана возраста составила 60 (49; 63) лет) и молодых условно здоровых добровольцах без АГ (n = 12, медиана возраста — 26 (25; 27) лет). Измерение микроциркуляции крови осуществляли методом лазерной допплеровской флоуметрии при помощи прибора ЛАКК-02. Регистрацию микроциркуляции на коже предплечья проводили в ходе окклюзионно-тепловой пробы. Для сравнения параметров в двух группах использовали критерий Манна–Уитни. Диагностическую точность метода при обратной классификации обследуемых по группам оценивали с применением ROC-анализа.</p></sec><sec><title>Результаты</title><p>Результаты. У пациентов с АГ медиана базовой перфузии составила 3,1 (1,84; 4,31) перфузионных единиц (ПЕ), у здоровых добровольцев 4,29 (3,66; 8,14) ПЕ (p = 0,04). Медиана площади под кривой микроциркуляции за 2 первые минуты нагрева у пациентов с АГ составила 1206,7 (813; 1449) ПЕ, у здоровых добровольцев 1552,3 (1310; 1624) ПЕ (p = 0,035). У здоровых добровольцев на фоне нагрева перфузия выросла на 596% (386 %; 878 %), а у пациентов с АГ — всего на 265 % (180%; 318%) (p = 0,01). Относительный прирост перфузии в период постокклюзионной гиперемии с продолжающимся нагревом по сравнению с базовым уровнем у здоровых добровольцев составил 651 % (493%; 999 %), а у пациентов с АГ — 302% (182 %; 436 %) (p = 0,005). Таким образом, при сравнении средних параметров на каждом из участков пробы значимые различия были получены только для базовой перфузии. Однако при переходе от абсолютных параметров к относительным (анализ увеличе ния микроциркуляции на фоне вазодилатирующих воздействий в процентах) удалось достичь не только статистической значимости различий, но и 75% чувствительности и 84,6% специфичности методики при обратной классификации групп.</p></sec><sec><title>Заключение</title><p>Заключение. Применение физиологических (использование локального нагрева кожи предплечья со скоростью 2 °C в секунду, комбинация вазодилатирующих воздействий) и математических (переход от абсолютных к относительным значениям) подходов позволило увеличить информативность метода лазерной допплеровской флоуметрии и добиться повышения его чувствительности и специфичности.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Hypertension (HTN) is associated with impaired skin microcirculation. Laser Doppler ﬂowmetry is an objective, quantitative, instrumental method that allows evaluating skin microcirculation. However, the method was not widely used clinically due to high variability of perfusion and small difference between healthy people and HTN patients and, as a consequence, low diagnostic signifcance.</p></sec><sec><title>Objective</title><p>Objective. To provide the grounds for the approaches increasing the informative value of skin microcirculation measurement by laser Doppler ﬂowmetry in HTN patients.</p></sec><sec><title>Design and methods</title><p>Design and methods. The study involved HTN patients (n = 13, the median age was 60 (49; 63) years) and young otherwise healthy volunteers without HTN (n = 12, the median age 26 (25; 27) years). Microcirculation measurement was performed by laser Doppler ﬂowmetry using LAKK-02 device. Registration of microcirculation on the forearm skin was carried out during the occlusionheating test. The Mann-Whitney test was used to compare the parameters in two groups. The diagnostic accuracy of the method for the inverse classifcation of the subjects was evaluated using ROC analysis.</p></sec><sec><title>Results</title><p>Results. In HTN patients, the median baseline perfusion was 3,1 (1,84; 4,31) perfusion units (PU), in healthy volunteers — 4,29 (3,66; 8,14) PU (p = 0,04). The median area under the microcirculation curve for the frst 2 minutes of heating in HTN patients was 1206,7 (813; 1449) PU × s, in healthy volunteers — 1552,3 (1310; 1624) PU × s (p = 0,035). In healthy volunteers, the heating increased the perfusion by 596 % (386%; 878%), and in HTN patients perfusion increased only by 265% (180 %; 318%) (p = 0,01). The relative increase in perfusion during postocclusion hyperemia with continued heating compared with the baseline in healthy volunteers was 651% (493 %; 999%), and in HTN patients — 302 % (182 %; 436%) (p = 0,005). Thus, when comparing the average parameters for each period in the occlusion-heating test, only basic perfusion showed signifcant differences. However, when changed from absolute to relative parameters (the increase in microcirculation in relation to the vasodilating effects), the difference was signifcant. Moreover, sensitivity achieved was 75 % and specifcity — 84,6% (the inverse classifcation of groups).</p></sec><sec><title>Conclusions</title><p>Conclusions. The physiological (the local heating of the forearm skin at a rate of 2 degrees Celsius per second, a combination of vasodilating effects) and mathematical (the transition from absolute to relative values) approaches provided an increase of the informative value of the laser Doppler ﬂowmetry, as well as its sensitivity and specifcity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертензия</kwd><kwd>лазерная допплеровская флоуметрия</kwd><kwd>микроциркуляция крови</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypertension</kwd><kwd>laser Doppler ﬂowmetry</kwd><kwd>blood microcirculation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Riva C, Ross B, Benedek GB.
