Head of Group
Somnology Group was established in 2013 as a separate division of the Research Department for Arterial Hypertension of the Heart and Vessels Institute. The specialists of the Research Department for Arterial Hypertension have been diagnosing and consulting patients for sleep disorders since 2002.
The specialists of Somnology Group carry out research on sleep disorders associated with cardiovascular, neurological and endocrine diseases and their influence on prognosis in various conditions. Based on these results, the Research Department for Arterial Hypertension performed and defended theses, including 3 PhD and 1 doctoral theses. Since 2014, more than 120 publications have been published, incl. more than 40 in Scopus and Web of Science.
Major areas of ongoing research
- Possibility of eliminating cardiac rhythm and conduction disorders in CPAP /BiPAP therapy at night time;
- Studies in patients with HF, sleep assessment before and after heart transplant surgery;
- Survey of St. Petersburg population as part of a large-scale epidemiological study to assess CVD in various regions of the Russian Federation (ESSE-RF);
- Studies on the role of sleep breathing disorders in arterial hypertension, resistant hypertension and metabolic disorders.
Collaboration and International Cooperation
- Bauman Moscow State Technical University (Moscow) – for developing non-contact methods for sleep disorder assessment
- With specialists in different areas (neurologists, endocrinologists, ENT specialists, psychologists and psychotherapists) of the leading institutions of St. Petersburg, Moscow, Petrozavodsk, Khanty-Mansiysk for an integrated approach to the diagnosis and treatment of various sleep disorders.
Somnology Group has been actively involved in international projects.
Since 2018, a multicenter randomized eSATIS study “Early Sleep Apnea Treatment in Stroke: A Multicenter, Randomized, Rater-Blinded, Clinical Trial of Adaptive Servo-Ventilation” (2018—2020) is being performed in the Almazov National Medical Research Centre. Main Centre and Sponsor) /Principal Investigator: Professor Claudio Bassetti (Department of Neurology, University Hospital Bern, Switzerland).
From 2018 to 2019, a new study was carried out with Tech Company Huawei (China) — «Automatic human sleep monitoring via smartphone and fitness tracker signals».
Since 2019, the study «Obstructive sleep apnea therapy in patients after bariatric surgery» was carried out with the support of «Lowenstein» company (Germany).
Membership in professional societies
European Sleep Research Society, Assembly of National Sleep Societies, International Society of Hypertension.
The specialists of Somnology Group regularly take part in international and national congresses and conferences of professional societies (Russian Society of Cardiology, European Society of Cardiology, International Society of Hypertension, National Sleep Society, European Sleep Research Society, World Sleep Society, All-Russian Society of Neurologists) and hold symposia, round tables, etc.
In 2019, the annual Assembly of National Sleep Societies was organized for the first time in Russia (in St. Petersburg).
The specialists of Somnology Group conduct outpatient appointments at the Diagnostic Centre, provide consultations to inpatients admitted to Almazov Centre.
All types of diagnostic devices (according to the AASM classification) are available to perform the following sleep tests: attended in-lab full video-polysomnography; unattended polysomnography in cardiology wards; cardiorespiratory monitoring (with a simultaneous 12-channel ECG monitoring) and night pulse oximetry with a simultaneous oronasal airflow recording. The last 2 types are screening tests and are used for as primary diagnostic tools only. Actigraphy is used for the evaluation of circadian rhythm disorders.
The laboratory can also select the treatment for sleep-related breathing disorders, primarily various modes of PAP (positive airway pressure) therapy, which is the treatment of choice for sleep apnea. If necessary, complex treatment using an oxygen concentrator is used. Patients receiving PAP therapy are followed up to assess the effect of therapy on the main clinical and laboratory parameters.
In addition to the diagnosis and treatment of sleep-related breathing disorders, somnology specialists focus on the detection, assessment and treatment of circadian rhythm sleep-wake disorders, and provide comprehensive diagnosis for patients with insomnia and other sleep disorders.
Together with the specialists of the Perinatal Centre, somnologists provide diagnosis and treatment of sleep disorders in children.
