We not past nor future a review of the English-language literature from 1972 between the walls of 2000 pertaining to systemic high BP in patients with sleep-disordered breathing (SDB) We reviewed studies assessing the relationship between obstructive lie in the grave apnea, central sleep apnea or periodic breathing, and systemic high BP and existing an approach to the management of these patients. Complications of obesity and the part of the sympathetic nervous rule are reviewed as well. It is the aim of these reviews to draw qualified conclusions, based in succession the current literature, with regard to SDB as a causative or contributory factor in systemic hypertension.

**********

Sleep-disordered breathing (SDB) is as a common thing [i]or[/i] matter found in conjunction with systemic hypertension. Determining cause and tenor in that relationship has been same difficult to demonstrate. An association between systemic hypertension and SDB was first recognized in the 1970 on Coccagna et al, (1) Lugaresi et al, (2) and Motta et al (3) in case reports of improvement in BP following surgical intervention for a variety of SDB question s The authors raised the possibility of cause-and-effect relationship between SDB and systemic hypertension. Since the publication of those case reports, numerous studies have been guarded to try to confirm or clarify this relationship. The American guild of Chest Physicians asked this panel to management a systematic and critical review of the literature, and to provide relevant conclusions regarding the evidence supporting SDB as a causative or contributory factor in systemic hypertension.

Several questions are addressed: Do patients with SDB have an increased incidence of systemic hypertension, and vice versa? Are there everyday factors to both, such as obesity, that contribute to the relationship? What is the part of the sympathetic nervous system? Does SDB treatment affect hypertension control? We report conclusions based upon an extensive literature review covering studies performed from 1970 by means of 2000. We begin with definitions. We identify inconsistencies in the literature. Discussions of cardiovascular pathology of SDB follow

Questions addressed include the following: Do patients with systemic hypertension have an increased incidence of nap apnea and altered response to hypoxia? Do the increased catecholamine plains associated with sleep apnea affect daytime systemic hypertension, or alter the risk of arrhythmias and ischemic issues in patients with coronary artery disease? What character is played by the sympathetic nervous system? What is the interplay of obesity, hypertension, and rest apnea, and can resulting hypoxia and hypercapnic acidosis be improved? Is there a relationship between be still apnea and ischemic heart disease and/or idiopathic dilated cardiomyopathy? Will SDB treatment affect hypertension control? Finally, we tabulate and summarize those clinical studies that have directly addressed these relationships, and issue to a consensus as to the conclusions that can commonly be drawn from these studies.

MATERIALS AND METHODS

Database Searches

For this review, the PubM database was systematically searched for articles published between 1972 and 2000 using keywords and the medical control heading terms to identify all human clinical studies specifically designed to assess the association between SDB and systemic hypertension, (3-61) and sympathetic nervous theory SDB, and systemic hypertension. (62-80) Studies were considered relevant if they addressed hypertension, arterial hypertension, or systemic hypertension in conjunction with obstructive or central be dead apnea, snoring, or periodic breathing disorders. the couple medical subject headings and keywords were used in searches, fit to concerns about potential accuracy of National Library of Medicine indexing.

Inclusion/Exclusion Criteria

solely randomized or nonrandomized control trials, observational, rule cohort (longitudinal), case control, cros sectional, uncontroll case series/cohort, time series, cross-cultural, ecologic, descriptive epidemiologic, and case reports were included. The literature search exclud pulmonary hypertension, editorials, position papers, editorial opinions, abstracts, and alphabetic characters to the editor. Exceptions to this authority were editorials, position papers, editorial opinions, or literal meanings to the editor that provided additional respects thought to be of relevance and not construct in the original search. All English-language articles identified in these searches and fitting these criteria were included for review.
