named after academician I.P. Pavlov Visokovoltnaya ul. 9, Ryazan, 390026 Russia Aim. To study the structure of risk factors and associated cardiovascular and concomitant non-cardiac diseases in patients with atrial fibrillation (AF) on the base of the data of registry, and to estimate diagnostics and treatment quality in real outpatient practice in the Ryazan region with high cardiovascular mortality rate. Material and methods. A total of 3690 patients with AF, arterial hypertension (HT), ischemic heart disease (IHD) and chronic heart failure (CHF) consulted by general practitioners and cardiologists in three outpatient clinics of Ryazan, were enrolled into the outpatient REgistry of CardioVAScular diseAses (RECVASA). 530 of 3690 (14.4%) patients had the "atrial fibrillation" diagnosis in their outpatient charts: 175 (33.0%) men, 355 (67.0%) women, and mean age -72.3±10.1 years. Results. Permanent, paroxysmal or persistent forms of AF were indicated in outpatient charts of 43.2%, 26.4% and 24.7% of 530 AF patients, respectively, and 5.7% of outpatient charts did not specify AF form. All the AF patients had associated cardiovascular diseases (HT and/or IHD and/or CHF). The history of myocardial infarction, stroke and diabetes was revealed in 20.2%, 14.9% and 21.1% of patients, respectively. Revealed level of diagnostics did not satisfy adequate standard of examination with such cardiac pathology. Prescription of necessary drugs of some groups was insufficient, although indications existed. At the time of being included into the registry only 15.2% of AF patients received cardio-vascular drugs at a privileged price compared to 39.2% in the preceding years (p<0.05). AF diagnosis was confirmed in 84.2% of 76 randomly selected patients at its validation. Conclusion. The RECVASA research revealed high incidence of cardiac comorbidity in patients with the AF, underestimation of cardiovascular risk factors, insufficient use of diagnostic tests and prescription of some drug groups recommended by national and international guidelines. Цель. Изучить структуру факторов риска, сочетанной сердечно-сосудистой и сопутствующей патологии у больных с фибрилляцией предсердий (ФП), а также оценить качество диагностики и лечения в реальной амбулаторно-поликлинической практике с помощью регистра на территории Рязанской области -субъекта РФ с высоким уровнем сердечно-сосудистой смертности. Материал и методы. В амбулаторно-поликлинический РЕгистр КардиоВАскулярных ЗАболеваний (РЕКВАЗА) включены 3690 больных ФП, артериальной гипертонией (АГ), ише-мической болезнью сердца (ИБС) и хронической сердечной недостаточностью (ХСН), обратившихся к терапевтам и кардиологам 3-х поликлиник г. Рязани. У 530 из 3690 боль-ных (14,4%) в амбулаторной карте был зафиксирован диагноз «фибрилляция предсердий», из них -175 (33,0%) мужчин и 355 (67,0%) женщин, средний возраст 72,3±10,1 лет. Результаты. Из 530 больных ФП постоянная, пароксизмальная и персистирующая формы ФП были указаны в амбулаторной карте в 43,2%, 26,4% и 24,7% случаях, соответ-ственно, а у 5...

Relationship between the size of the molecule in the series of organic ions Et3+N--(CH2)5--+NR1R2R3 (Ri--alkyl or cycloalkyl substituents) and their abilities to block nicotinic acetylcholine receptors (AChRs) due to their open-channel blockade in the neurons of autonomic ganglia and in frog end-plate was analyzed. All low-energy equilibrium conformations of the drugs were calculated by the molecular mechanics method. A unique rectangular channel profile 6.1 x 8.3 A, for which the best correlation between blocking activity of the drugs and total population of their conformations being able to penetrate into the channel, was deduced from all those tested.

Outpatient register of cardiovascular diseases in the Ryazan Region (RECVASA): principal tasks, experience of development and first results

Forty-three bisammonium ganglionic blockers were synthesized to study the structure of the ion channel of nicotinic acetylcholine receptor. The conformational parameters of these blockers were studied, and their effects toward the ganglionic transmission in situ on the sympathetic feline upper cervical ganglions and in vitro on the parasympathetic guinea-pig small intestine ganglions were determined. A model of the binding site for the bisammonium ganglionic blockers in the neuronal ion channel was proposed.
