OBJECTIVES/HYPOTHESIS Sleep apnea is associated with hypertension and diabetes, putting these patients at high risk for developing cardiovascular disease. The goal of this study was to identify the individual cardiovascular risk profile and to detect premature and undiagnosed disease in patients with various degrees of sleep apnea. STUDY DESIGN Cross-sectional. METHODS Over a 6-month period...

STUDY OBJECTIVES The objective was to investigate the prevalence of heart attack, angina pectoris, stroke, hypertension, diabetes mellitus, chronic obstructive pulmonary disease, asthma and obesity in relation to the presence and severity of obstructive sleep apnea. METHODS The sample consisted of 1887 patients, with mean age of 48.6 years (range 16-83 years), referred to a university hospita...

The aim of this study was to analyze one year survival outcome of the patients with sleep apnea in acute stroke in order to type and localisation of lesion. Patients and Methods: It was analyzed 110 patients with acute stroke (AS) and verified sleep apnea, treated at Department of Neurology, University Clinical Center Tuzla in the period December 2009 thorough may 2010. Acute stroke has been ve...

What We Found § Though far fewer than the 1995 study found, 4.7% of commercial drivers in the study were found to have severe sleep apnea. Another 5.8% had moderate sleep apnea and 17.6% has mild sleep apnea. § Prevalence of moderate to severe sleep apnea is twice as high among CDL holders no longer currently employed as drivers, suggesting that the industry may be losing valuable drivers becau...

STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

STUDY OBJECTIVES Some patients with apparent obstructive sleep apnea hypopnea syndrome (OSAHS) have elimination of obstructive events but emergence of problematic central apneas or Cheyne-Stokes breathing pattern. Patients with this sleep-disordered breathing problem, which for the sake of study we call the "complex sleep apnea syndrome," are not well characterized. We sought to determine the p...

OBJECTIVE To examine whether circulating leptin levels correlate with the severity of disease in patients with obstructive sleep apnea. DESIGN Prospective nonrandomized study. SETTING Referral sleep laboratory for patients with sleep-disordered breathing and biochemistry laboratory. Patients Thirty-two subjects (mean +/- SD age, 47 +/- 12 years) who were referred for suspected sleep apnea u...

OBJECTIVE To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. METHODS We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth ...

Over the past few decades, sleep apnea has emerged as an important potential etiologic factor in a broad range of cardiac and vascular diseases. These disease conditions include hypertension, coronary artery disease, myocardial infarction, heart failure, and stroke. Recognition of the role of sleep apnea in clinical cardiology is also increasing in Japan. Although sleep apnea has been strongly ...
