Проводилось обследование, включавшее первичный опрос, осмотр, эхокардиографию (ЭхоКГ) и холтеровское мониторирование (ХМ) ЭКГ. В ходе ХМ ЭКГ оценивали mTWA и ТРС. Для ТРС определялись показатели turbulence onset (ТО) и turbulence slopе (TS). В зависимости от результатов ЭхоКГ группа больных с ГБ была разбита на 2 подгруппы: с ГЛЖ (14 мужчин, женщина, средний возраст 59,3 ±10,4 лет) и без ГЛЖ (20 мужчин, 16 женщин, средний возраст 59,1±11,4 лет). Контрольная группа была разделена на 2 подгруппы. Подгруппа №1 (24 мужчины, 26 женщин, средний возраст 38,6±20 лет) использовалась для сравнения с группой ГКМП, подгруппа №2 (24 мужчины, 16 женщин, средний возраст 59±16 лет) - для больных с ГБ. Нарушения ТРС первого встречались у 18% пациентов с ГКМП и у 1 в группе контроля (2%, p&lt;0,05). При анализе показателей mTWA, обнаружено, что больные с ГКМП характеризовались достоверно более высокими значениями mTWA05:00 по сравнению с группой контроля. При проведении корреляционного анализа в группе пациентов с ГКМП не выявлено значимой связи показателей mTWA с толщиной миокарда ЛЖ за исключением слабой обратной корреляции тМЖП и mTWA100 во втором отведении при ФА 1/32 (rs= - 0,320, р&lt;0,05). Таким образом, для больных с ГКМП по сравнению с контролем характерна более высокая частота нарушений ТРС (прежде всего ТО) и более высокие значения mTWA, измеренной в предутренние часы, однако связь выявленных нарушений со степенью ГЛЖ либо минимальна, либо отсутствует. У пациентов с ГБ и ГЛЖ нарушения ТРС встречались достоверно чаще, чем в контрольной группе (40% и 12,5% соответственно, p&lt;0,05). При корреляционном анализе в общей группе больных с ГБ (n=71) выявлена слабая положительная связь ТО с тЗС (rs= 0,376, р&lt;0,05). При анализе показателей mTWA выявлены достоверно более высокие значения mTWA (ФА 1/8 и 1/32, первое отведение) в группе больных с ГБ и ГЛЖ по сравнению с контролем. Таким образом, пациенты с наличием ГЛЖ вследствие ГБ или ГКМП характеризуются большей частотой нарушения ТРС и более высокими значениями mTWA5:00, по сравнению с лицами без сердечно-сосудистой патологии, однако корреляционная связь выраженности данных изменений со степенью ГЛЖ либо отсутствует (mTWA5:00), либо минимальна (TO).</p></abstract><trans-abstract xml:lang="en"><p>To study peculiar features of heart rate turbulence (HRT) and microvolt T-wave alternations (mTWA) in patients with hypertrophic cardiomyopathy and arterial hypertension with the left ventricular hypertrophy (LVH), examined were 50 patients aged 40.6±18.3 years with hypertrophic cardiomyopathy (25 men and 25 women), 71 patients aged 59.2±10.9 years with arterial hypertension (34 men and 37 women), and 90 subjects aged 47.8±20.7 years (48 men and 42 women) free of cardiovascular diseases. The examination was carried out, which included collection of historical data, physical examination, echocardiography, and ECG Holter monitoring. During ECG Holter monitoring, mTWA and HRT were assessed. The turbulence onset (TO) and turbulence slope (TS) indices were calculated when assessing HRT. Based on the results of echocardiographic assessment, the patients with arterial hypertension were distributed into two following subgroups: subjects with LVH (14 men and 21 women aged 59.3±10.4 years) and patients without LVH (20 men and 16 women aged 59.1±11.4 years). The control group was divided into 2 subgroups, as well. Subgroup 1 (24 men and 26 women aged 38.6±20 years) was used for comparison with the hypertrophic cardiomyopathy subjects, Subgroup 2 (24 men and 16 women aged 59±16 years), for comparison with arterial hypertension subjects. Alterations of the first HRT were noted in 18% of patients with hypertrophic cardiomyopathy and 1 patient of control group (2%, p&lt;0.05%). The analysis of mTWA parameters showed that the hypertrophic cardiomyopathy subjects were characterized by higher values of mTWA05:00 as compared with the control group. The correlation analysis in the patients with hypertrophic cardiomyopathy did not show significant correlation of mTWA indices with the width of the left ventricular (LV) myocardium, excluding mild negative correlation of the inter-ventricular septum width and mTWA100 in Lead II in FA 1/32 (rS=-0.320, p&lt;0.05). Thus, the patients with hypertrophic cardiomyopathy as as opposed to control group are characterized by a higher occurrence of HRT disturbances (mainly, TO) and higher levels of mTWA recorded in early pre-morning hours. However, the correlation of the alterations observed with the LVH extent either was not revealed or was of the minimal extent. In patients with arterial hypertension and LVH, the HRT alterations were revealed more frequently than in control group (40% and 12.5%, respectively; p&lt;0.05). The correlation analysis in the overall patient group with arterial hypertension (n=71) showed a slight positive correlation of TO with the posterior wall width (rS=0.376, p&lt;0.05). The analysis of mTWA parameters showed significantly higher levels of mTWA05:00 (FA 1/8 and 1/32, Lead I) in the patients with arterial hypertension and LVH as compared with control group. Thus, the patients with LVH due to arterial hypertension and hypertrophic cardiomyopathy are characterized by a higher incidence of HRT alterations and higher levels of mTWA05:00 as opposed to the subjects free of cardiovascular diseases; however, the correlation of the above alterations with the LVH extent is either absent (mTWA05:00) or is minimal (TO).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>турбулентность ритма сердца</kwd><kwd>микровольтная альтернация зубца Т</kwd><kwd>гипертрофическая кардиомиопатия</kwd><kwd>гипертоническая болезнь</kwd><kwd>гипертрофия левого желудочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart rate turbulence</kwd><kwd>microvolt T-Wave alternations</kwd><kwd>hypertrophic cardiomyopathy</kwd><kwd>essential hypertension</kwd><kwd>left ventricular hypertrophy</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">American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society Scientific Statement on Noninvasive Risk Stratification Techniques for Identifying Patients at Risk for Sudden Cardiac Death // Circulation. - 2008. - Vol. 118. - P. 1497 - 1518.</mixed-citation><mixed-citation xml:lang="en">American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society Scientific Statement on Noninvasive Risk Stratification Techniques for Identifying Patients at Risk for Sudden Cardiac Death // Circulation. - 2008. - Vol. 118. - P. 1497 - 1518.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">ACC/AHA/ESC 2006 guidelines for management of patients with ventricular arrhythmias and the prevention of sudden cardiac death // Europace. - 2006. - Vol. 8. - P. 746-837.</mixed-citation><mixed-citation xml:lang="en">ACC/AHA/ESC 2006 guidelines for management of patients with ventricular arrhythmias and the prevention of sudden cardiac death // Europace. - 2006. - Vol. 8. - P. 746-837.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Casale PN, Devereux RB, Milner M et al.
