В исследование включены 56 пациентов с ФП (средний возраст – 57,1±8,4 лет, из них 25 женщин), в том числе 47 с пароксизмальной и 9 с персистирующей ФП, госпитализированных в клинику с целью первичной катетерной аблации (КА). Для оценки структурно-функционального состояния сердца выполнялась трансторакальная эхокардиокардиография. На основании расчетов индекса массы миокарда ЛЖ (ИММЛЖ) и относительной толщины стенки (ОТС) ЛЖ все пациенты были разделены на группы по типу геометрии ЛЖ: 1) нормальная геометрия (n=27): нормальный ИММЛЖ (≤95 г/м2 для женщин и ≤115 г/м2 для мужчин) и ОТС≤0,42; 2) концентрическое ремоделирование (n=13): нормальный ИММЛЖ и ОТС&gt;0,42; 3) концентрическая гипертрофия (n=6): увеличение ИММЛЖ и ОТС&gt;0,42; 4) эксцентрическая гипертрофия (n=10): увеличение ИММЛЖ и ОТС≤0,42. Оценка размеров фиброза ЛП была основана на выделении низковольтажных зон (&lt;0,5 мВ) во время биполярного вольтажного электроанатомического картирования (ВЭК) как первого этапа КА. Рассчитывались следующие показатели: общая площадь фиброза (Sф), доля фиброза (%) от общей площади ЛП Sф (%), степень фиброза (по аналогии со шкалой оценки фиброза UTAH) и количество зон фиброза. У всех пациентов определялся уровень NT-proBNP в крови. Фракция выброса ЛЖ (ФВЛЖ) была в норме у всех пациентов.Результаты. С помощью анализа по Спирмену подтверждено наличие положительной связи Sф, Sф (%) с диаметром ЛП, ИММЛЖ и уровнем NT-proBNP, а также выявлена отрицательная связь Sф, Sф (%), степени фиброза ЛП с ФВЛЖ. Было установлено, что такой тип геометрии ЛЖ, как эксцентрическая гипертрофия ассоциируется со статистически значимо более высоким количеством зон фиброза по сравнению с нормальной геометрией сердца, в то время как при других типах геометрии статистически значимых различий показателей фиброза по сравнению с нормальной геометрией сердца не получено.Заключение. Таким образом, выраженность фиброза ЛП ассоциирована с размерами ЛП, функциональным состоянием ЛЖ и типом геометрического ремоделирования ЛЖ.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To investigate the relationships between left atrial (LA) fibrosis extent and left ventricular (LV) structural and functional status in patients (pts) with nonvalvular atrial fibrillation (AF).Material and Methods. The study enrolled 56 pts (mean age 57.1±8.4 years, 25 females), admitted to hospital for primary catheter ablation (CA), including 47 pts with paroxysmal AF and 9 pts with persistent AF. All pts had scheduled transthoracic echocardiography to measure size and volume of cardiac chambers and systolic and diastolic functions of the left ventricle. Based on the calculation of the LV mass index (LVMI) and relative wall thickness (RWT), we categorized all pts into 4 groups: (1) normal geometry (n=27); (2) concentric remodeling (normal LVMI and high RWT, n=13); (3) concentric hypertrophy (high LVMI and high RWT, n=6); and (4) eccentric remodeling (high LVMI and normal RWT, n=10). The assessment of LA fibrosis sizes was based on the allocation of low voltage zones (&lt;0.5 mV) in the process of voltage electroanatomic mapping (VEM) as the first stage of CA. Following indicators were calculated: total square of fibrosis (Sf), % of fibrosis from the total LA square (Sf%), the degree of LA fibrosis (an analog of the UTAH score), and number of LA fibrosis zones. Level of NT-proBNP in blood was determined among other laboratory tests. All pts had preserved LV ejection fraction (LVEF).Results. Results of the study confirmed positive relationships between Sf, Sf% and LA diameter, LVMI, and NT-proBNP level. Negative relationship was noted between Sf, Sf%, the UTAH degree and LVEF. Such LV geometry type as eccentric hypertrophy was associated with a higher number of LA fibrosis zones compared to the normal LV geometry, while significant differences in other types of geometry were not found.Conclusion. Thus, LA fibrosis extent was associated with LA size, LV function, and LV geometric remodeling pattern.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>фиброз левого предсердия</kwd><kwd>ремоделирование левого желудочка</kwd><kwd>диастолическая дисфункция левого желудочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>left atrial fibrosis</kwd><kwd>left ventricular remodeling</kwd><kwd>left ventricular diastolic dysfunction</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">Majeed A., Moser K., Carroll K.
