Sleep apnea syndrome (SAS) disturbing the structure of normal sleep causes many diseases. Contemporary studies prove that apnea is an independent risk factor for hypertension and myocardial infarction. Moreover it is emphasized that SAS plays important role in the initiation of arrhythmias, left ventricle dysfunction, pulmonary hypertension, endocrinological disorders and many others. That is the reason of worsened quality of life and increased mortality, mainly as a consequence of cardiovascular complications or high accident rate. Early diagnosis and treatment's application allows to improve the prognosis in these patients. This article recapitulates the knowledge in the field of SAS complications and the potential mechanisms of their development.
