Кардиоселективные β-адреноблокаторы (например, метопролол) рекомендованы для лечения больных с АГ [1]. Появление β-адреноблокаторов (БАБ) с вазо-дилатационной активностью (карведилол), влияю-щих на периферическое сосудистое сопротивление по-средством блокады α 1 -рецепторов, представляется до-статочно перспективным. Сравнительных исследова-ний влияния кардиоселективных БАБ и БАБ с вазоди-латационной активностью на вегетативную дисфунк-цию у больных АГ не проводилось.Существует мнение, что низкочастотные колебания с частотой около 0,1 Гц, выявляемые в различных от- Цель. Изучить влияния карведилола и метопролола на вегетативную регуляцию сердца и микроциркуляторного русла (МЦР) у больных артериальной гипертонией (АГ) 1-2-й степени и избыточной массой тела/ожирением. Материал и методы. В исследование включили 25 больных АГ 1-2-й степени в возрасте 51±8 лет. Регистрация колебаний вариабельности сердечного ритма (ВСР) в диапазоне 0,1 Гц и кровенаполнения МЦР производилась в ходе пассивной ортостатической пробы при спонтанном дыхании продолжительностью каждого этапа пробы 10 мин. Синхронизацию 0,1 Гц-ритмов оценивали вычислением разности фаз и численной меры синхронизации. Дополнительно получали частотные оцен-ки спектра ВСР в высокочастотном и низкочастотном диапазонах. Результаты. Карведилол и метопролол оказывали сопоставимый гипотензивный эффект и влияние на вегетативную регуляцию системы кровообращения у больных АГ. При исходно высоком уровне систолического артериального давления (>150 мм рт.ст.) применение обоих препаратов негативно влияло на синхронизацию 0,1 Гц-ритмов. Заключение. Карведилол и метопролол оказывают сопоставимое влияние на синхронизацию 0,1 Гц-ритмов в системе кровообращения. Aim. To study effects of carvedilol and metoprolol on vegetative regulation of heart and microcirculatory vessels in patients with arterial hypertension (HT) of 1-2 degrees and high body mass/obesity. Material and methods. Patients with HT of 1-2 degrees (n=25; aged 51±8 y.o.) were included in the study. Registration of 0,1 Hz-fluctuations in heart rhythm variability and microcirculation change was performed during passive orthostatic test at spontaneous breath (duration of each test stage 10 min). Synchronization of 0,1 Hz-rhythms was estimated by calculation of phases difference and a numerical measure of synchronization. Frequency estimations of heart rhythm variability spectrum were performed in high and low frequency ranges additionaly.Results. Carvedilol and metoprolol have the comparable antihypertensive effect and influence on vegetative regulation of cardiovascular system in patients with HT. Both drugs have negative influence on synchronization of 0,1 Hz-rhythms in initially high systolic blood pressure level (>150 mm Hg). Conclusion. Carvedilol and metoprolol have comparable influence on synchronization of 0,1 Hz-rhythms in cardiovascular system.
Aim. To study possibility of using the evidence-based clinical-andmorphological appropriate use criteria for percutaneous coronary interventions (PCIs) for expert evaluation of high-technology procedures implementation in patients with acute coronary syndrome (ACS) in Russia.Materials and methods. The appropriateness of performed PCI was assessed in patients with ACS, underwent coronary revascularization. The potential need in PCI was determined in ACS patients refused from coronary revascularization. Assessment was performed with the help of ACCF/SCAI/STS/AATS/AHA/ASNC/HFSA/SCCT 2012 Appropriate Use Criteria for Coronary Revascularization Focused Update (ACCF 2012). Data from 65,912 ACS patients, containing in Russian ACS Registry (2010–2011) were examined.Results. ACCF 2012 criteria allow to assess the clinical appropriateness of PCI in 79.2% of patients underwent coronary revascularization and to determine the potential need in PCI in 80.6% of patients, refrained from coronary revascularization. Among ACS patients underwent PCI (n=9147), intervention was appropriate in 68.9% of cases. Inappropriate PCI was revealed in 4.6% of cases. Among patients refrained from PCI (n=56765), coronary revascularization was potentially appropriate in 57.9% of cases.Conclusion. ACCF 2012 clinical-and-morphological criteria allow to judge on appropriateness of performed PCI and to evaluate the potential need in PCI among the most part of Russian ACS patients. In present study coronary revascularization was appropriate in the majority of ACS patients. It was shown possible to use the evidence-based clinical-andmorphological criteria for expert evaluation of high-technology procedures implementation in Russian ACS patients.
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.
