Діастолічна функція лівого шлуночка та рівень N-кінцевого промозкового натрійуретичного пептиду у хворих на фібриляцію передсердь
In our study 100 consecutive non-valvular permanent atrial fibrillation patients with NYHA I – III heart failure, 43 - 86 years old (65 men and 35 women) were examined. Control group consisted of 30 patients with arterial hypertension and coronary artery disease matched by age, sex with basic group. Relationship of NT-proBNP with echocardiographic parameters of left heart were studied. Transthoracic echocardiography with tissue doppler measurements were performed on echocardiograph “SONOS7500”. For left ventricular filling pressure assessment ratio Em/Ea was used due to its diagnostic value in atrial fibrillation (regardless of left ventricular ejection fraction). Mean left ventricular filling pressure was increased in patients with heart failure: in atrial fibrillation group and controls as well. In comparison with controls atrial fibrillation group was more likely to have higher both systolic and diastolic left atrial square and volume. According to Em/Ea in 95% of patients with non-valvular atrial fibrillation high left ventricular filling pressure was observed, this testifies to diastolic dysfunction. This parameter correlated well with left atrial square and volume during systole and diastole. Correlation between NT pro-BNP level and NYHA class of heart failure, left ventricular filling pressure was determined in patients with atrial fibrillation. Tissue doppler echocardiography makes it possible to diagnose left ventricular diastolic dysfunction in atrial fibrillation patients.Обследовано 100 пациентов с постоянной формой фибрилляции предсердий неклапанного генеза и хронической недостаточностью І – ІІІ функционального класса в возрасте 43 – 86 лет, из них 65 мужчин и 35 – женщин. Контрольную группу составили 30 пациентов с ИБС и ГБ, сопоставимых по возрасту и полу с основной группой. Изучали уровень N-проМНП и его связь с эхокардиографическими показателями функции левых отделов сердца у данной категории больных. Эхокардиографическое исследование и тканевая допплерография проводились на аппарате «SONOS 7500». Для оценки давления наполнения левого желудочка рассчитывали соотношение Em/Ea, которое полностью сохраняет свое диагностическое значение (независимо от фракции выброса левого желудочка) при фибрилляции предсердий. Средний показатель давления наполнения левого желудочка был увеличен у больных с хронической сердечной недостаточностью, как при постоянной фибрилляции предсердий, так и на фоне синусового ритма. Было установлено достоверное увеличение размеров левого предсердия, его площадей и объемов в систолу и диастолу в группе пациентов с фибрилляцией предсердий в сравнении с группой контроля. По данным показателя Еm/Eaу 95% пациентов с фибрилляцией предсердий неклаппаного генеза выявлено повышение давления наполнения левого желудочка, что свидетельствует о нарушении диастолической функции. Данный показатель достоверно коррелировал с объемами и площадями левого предсердия в систолу и диастолу. Установлена достоверная связь между уровнем N-проМНП и функциональным классом сердечной недостаточности, уровнем давления наполнений левого желудочка у пациентов с фибрилляцией предсердий. Использование тканевого допплеровского исследования позволяет диагностировать нарушение диастолической функции левого желудочка при фибрилляции предсердий.In our study 100 consecutive non-valvular permanent atrial fibrillation patients with NYHA I – III heart failure, 43 - 86 years old (65 men and 35 women) were examined.

ASSOCIATION OF DNA REPAIR GENE POLYMORPHISM WITH CHROMOSOMAL ABERRATIONS IN THE BLOOD LYMPHOCYTES OF PATIENTS WITH LUNG CANCER
Analysis of association, between several DNA repair gene polymorphisms and the level of chromosomal aberrations (CAs) in lymphocytes was performed in two groups: a group of 215 patients with lung cancer and a control group of 152 donors. In the group patient with lung cancer the level of CAs shows a significant increase in the carrier of genotypes: XPD TG and XPD GG vs XPD TT. In the control group level of CAs shows a significant increase in the carrier of genotype ADPRT ТС vs ТТ
THE ASSOCIATION OF IMMUNE RESPONSE TO XENOAND ENDOBIOTIKS AND THEIRS BIOTRANSFORMATION ENZYME GENE POLYMORPHISM WITH CONGENITAL MALFORMATIONS OF THE FETUS
The correlation between immune response to benzo(a)pyrene and progesterone in combination with detoxification enzyme gene polymorphism (CYPIA2*1F and GSTTI) and the occurrence of congenital malformations of the fetus was revealed. It is shown that at high ratio of IgA-antibodies to benzo(a)pyrene and to progesterone in conjunction with the mutant allele of the gene CYPIA2*1F and the deletion genotype of the gene GSTTI chance of the reproductive pathology developing increases to 41 times
