Background. Cardiovascular disease (CVD) is one of the main causes of morbidity and mortality among adults worldwide. On another hand, obstructive sleep apnea syndrome (OSAS) is common in patients with CVD, and can worsen the patients prognosis due to late diagnosis. Aim: to analyze and summarize the published researches about interrelation between CVD and OSAS, its influence on CVD, and the effects of continuous airway pressure (CPAP) treatment of OSAS on CVD in order to pay attention to OSAS potential risks, improve the investigation of this syndrome and management. Materials and methods. Review of scientific literature in the international electronic scientometric databases PubMed, Google Scholar by key words for the period 2008-2023. The search was carried out by two independent authors. 150 sources were selected, 48 English–language articles of which met all the search criteria and were used for analysis. Results. OSAS is one of the widespread sleep disorders that frequently occurs in patients with CVD, impairs quality of life. Its increases cardiovascular and all-cause mortality and cardiovascular morbidity. OSAS is observed in patients with arterial hypertension in 30-83%, coronary heart disease in 38-65%, stroke in 57-65%, heart failure in 12-55%, heart rhythm disorders - in 20-50%. In addition, the relationship between OSAS and diabetes, metabolic syndrome, insulin resistance, depression, and cognitive impairment has been established. OSAS is often not diagnosed or not diagnosed in time. Thus, there are data that 86-95% OSAS, clinically manifestated, were missed diagnosis, that worsens the prognosis of such patients. Conclusions. OSAS is a common sleep breathing disorder in patients with CVD that is often diagnosed late. Most studies have shown that OSAS worsens the CVD course and outcomes. Therefore early diagnosis and timely appropriate treatment reduce morbidity and mortality.

Coronary artery disease (CAD) is a significant cause of morbidity and mortality globally, and hypertension, dyslipidemia, diabetes mellitus, and smoking are major cardiovascular (CV) risk factors. Obstructive sleep apnea (OSA) and CAD share an exciting relationship, and recently, OSA has emerged as a non-traditional CV risk factor. OSA is characterized by episodic sleep state-dependent collapse of the upper airway, resulting in periodic reductions or cessations in ventilation, with consequent hypoxia, hypercapnia, or arousals from sleep. The oxidative stress and vascular inflammation resulting from the nocturnal hypoxia followed by reoxygenation cycles predispose the patients to the development of atherosclerotic cardiovascular disease (CVD). Untreated OSA is associated with long-term health consequences, including CVD, metabolic disorders, cognitive impairment, and depression. Paradoxically, some recent studies have reported that patients with OSA may suffer less severe CAD due to the development of collateral circulation due to repetitive hypoxia experienced due to OSA.

“…It also has an impact on brain function and alters the architectural structure of the brain. The most common symptoms of the OSA is linked to reduced excessive daytime drowsiness through a number of processes, such as impaired blood–brain barriers, brain edema, and amyloid deposition, alterations in cerebral anatomy, altered anatomical brain connections, and blood—brain barrier failure 1 .…”

“…As a result, it's probable that impairments in the regional functional magnetic resonance imaging (fMRI) responses to emotions, evoked cognitive function, dyspnea, and sensorimotor function are the result of abnormalities in different insular sub regions. Studies on the functional activity of the brain in OSA patients have significantly highlighted deviations in the insula 1 . Fractional anisotropy (FA) measurement was suggested by Lee et al 6 as a way to check if people with OSA have changed brain network connections.…”

Obstructive sleep apnea (OSA) is a disorder which blocks the upper airway during sleep. The severity of OSA will lead heart attack, stroke and end of life. This proposed study explored the classification of OSA and healthy subjects using brain connectivity analysis from electroencephalogram (EEG) signals. Institute of System and Robotics—University of Coimbra (ISRUC) database were used for acquiring 50 EEG signals using 4 channels and noise removal has been accomplished by 50 Hz notch filter. The Institute of System and Robotics—University of Coimbra (ISRUC) database contained 50 EEG signals, with four channels, and a 50 Hz notch filter was applied to remove noise. Wavelet packet decomposition method was performing the segregation of EEG signals into five bands; Gamma (γ), beta (β), alpha (α), theta (θ) and delta (δ). A total of 4 electrode positions were used for the brain connectivity analysis for each EEG band. Pearson correlation method was effectively used for measuring the correlation between healthy and OSA subjects. The nodes and edges were highlighted the connection between brain and subjects. The highest correlation was achieved in delta band of OSA subjects which starts from 0.7331 to 0.9172 respectively. For healthy subjects, the positive correlation achieved was 0.6995. The delta band has been correlated well with brain when compared other bands. It has been noted that the positive correlation well associated with brain in OSA subjects, which classifies OSA from healthy subjects.
