Sleep Medicine Laboratory


Sleep Medicine Laboratory was opened in 2013 as an independent structural Division and part of the Research Department for Hypertension of the Institute of Heart and Vessels of Federal Almazov North-West Medical Research Centre. However, medical staff of the Research Department for Hypertension has been consulting patients for sleep disorders since 2002. Doctor Yurri Sviryaev is the Head of the laboratory (Hirsh index Russian Citation index – 4.0, Hirsh index Scopus – 2.0).

The staff of the Sleep Medicine Laboratory had passed the training in the leading worldwide laboratories (Center for Circadian and Sleep Medicine, Northwestern University Feinberg School of Medicine, Chicago, Il, USA; Neurocentro della Svizzera Italiana, Lugano, Switzerland; Sleep-Wake-Epilepsy Centre, Bern University Hospital, Switzerland; ESRS Marie Curie project “Training in Sleep Research”), and are certified by ESRS (certificates “Somnologist – Expert in Sleep Medicine”).


Clinical, research and education activities are implemented by the lab staff.

Clinical work

Clinical work includes both out-patient and in-patient consulting in the Federal Almazov North-West Medical Research Centre.

All 4 types of diagnostic devices (according to the AASM classification) are available in the lab, including attended in-lab full video-polysomnography; unattended polysomnography; cardiorespiratory monitoring (with a simultaneous 12-channel ECG monitoring) and night pulseoximetry with a simultaneous oronasal airflow registration. The last 2 types are considered to be screening tools, and are used for the primary diagnostics only. For the diagnostics of circadian rhythm disorders actigraphy is also available.

In addition, different types of therapeutic devices for CPAP/BiPAP-therapy are available in the laboratory, and titration sleep studies are performed for better choice of treatment regimen and pressure level. Patients who get CPAP/BiPAP therapy are followed-up, and the impact of pathogenetic treatment on clinical and laboratory parameters, prognosis, and the benefits of therapy in the management of heart rhythm and conductive disturbances are assessed. A complex application of non-invasive ventilation is performed in the laboratory, and if necessary oxygen-concentrator is used along with CPAP/BiPAP-therapy.

Besides sleep breathing disorders, the diagnostics and management of circadian rhythm disorders are also implemented. We are involved in the complex diagnosis of patients with insomnia and other sleep disorders. We collaborate with experts in various fields (neurology, endocrinology and Ear Nose Throat doctors) working in the Federal Almazov North-West Medical Research Centre and other leading institutions in St. Petersburg. It allows us to provide an integrated approach to the diagnosis and treatment of various sleep disorders.

Diagnosis and correction of sleep disorders in children is provided by the medical staff of the Perinatal Center of Federal Almazov North-West Medical Research Centre.


Clinical research focuses on sleep disorders and their association with cardiovascular diseases, their prognostic role and prevention approaches. As a result, 3 candidate and one doctoral theses were defended.
The ongoing research includes the studies of effects of PAP-therapy on heart rhythm and conduction disorders. Within the International Project “Seventh Framework Programme” patients with congestive heart failure are also examined and followed-up in sleep laboratory. A project directed at sleep disorders assessment in patients referred for heart transplantation has been initiated. We provide a survey of the St. Petersburg population with the Research Laboratory for Epidemiology of Hypertension as a part of the large-scale epidemiological studies to assess cardiovascular disease in different regions of the Russian Federation.
Together with pediatricians from the Perinatal Centre we assess the role of sleep disorders for neurocognitive development, emotional and behavioral characteristics and metabolic parameters in children.

Sleep Medicine Laboratory collaborates within colleagues from Almazov North-West Federal Medical Research Centre (neurologists, endocrinologists, ENT-doctors, psychologists and psychotherapists), as well as with different national and foreign institutions. The national collaborators include Institution of the evolutionary physiology and biochemistry n.a. I.M. Sechenov, First Pavlov State Medical University of St. Petersburg, Herzen State Pedagogical University of Russia, Clinical Multidisciplinary Clinic № 2, St Petersburg Clinical Hospital of Russian Academy of Sciences, Sleep Medicine Centre at the Federal Research Clinical Centre FMBA in Moscow etc. Together with INKART company the sleep diagnostic algorithms are being developed for the further implementation in the portable electrocardiogram and blood pressure monitoring systems.
The international collaborators include Bern University Hospital (Professor CL Bassetti, Head, Department of Neurology, Switzerland), Medical University of Gdansk (Professor K. Narkiewicz, Head, Department of Hypertension and Diabetology, Poland), S. Luca Hospital, IRCS Istituto Auxologico Italiano (Professor G. Parati, Department of Cardiology, Milan).

Social activities

The personnel of the Sleep Medicine Laboratory actively participates in different social events, propagates healthy sleep and popularizes prevention and treatment of sleep disorders: presents lectures for people with cardiovascular and other diseases, gives interviews on TV, radio and other media.
In 2014 and 2015, together with somnologists from Moscow different activities for the World Sleep Day were organized. The activity was awarded by the World Association of Sleep Medicine: “Distinguished Activity Award” 2014 and 2015.
