[Sleep-related breathing disorders and (resulting) cardiovascular diseases].
Sleep-related breathing disorders occur in cardiology patients mostly as obstructive or central sleep apnea with Cheyne-Stokes respiration. The prevalence and incidence are clearly increased in comparison to the general population. Depending on the underlying cardiac disease up to 75% of patients can have obstructive or central sleep apnea and up to 50% have indications for therapy according to the current guidelines. Obstructive sleep apnea is considered to be an independent and well treatable risk factor for the development and deterioration of many cardiovascular diseases. This review briefly describes examples of prevalence, pathophysiology and current study situation with respect to the association between sleep-related breathing disorders and arterial hypertension, atrial fibrillation, arteriosclerosis with coronary heart disease, myocardial infarction and heart failure. Although the role of obstructive sleep apnea as a risk factor for the development of these diseases is well documented, central sleep apnea is less of a risk factor per se but is considered to mirror an underlying cardiac disease with then further negative consequences for this disease. It is not the sleep apnea per se but the subsequent cardiovascular diseases which limit the prognosis of these patients and therefore bring them into the focus of cardiology. Obstructive and central sleep apnea can be successfully and sustainably treated by various forms of nocturnal positive airway pressure therapy. Furthermore, there are several therapeutic procedures which are currently being tested and the significance will be investigated in the coming years.
