Obstructive Sleep Apnea Syndrome Affects Left Ventricular Diastolic Function

Obstructive Sleep Apnea Syndrome Affects Left Ventricular Diastolic Function Effects of Nasal Continuous Positive Airway Pressure in Men

Background—The purpose of this study was to determine the role of obstructive sleep apnea syndrome (OSAS) as an independent risk factor for the development of left ventricular diastolic abnormalities. Moreover, we tested the hypothesis that nasal continuous positive airway pressure (nCPAP) improves such alterations in OSAS patients by eliminating apneic events. Methods and Results—In this prosp...

left ventricular mass index and pulmonary artery pressure in patients with the obstructive sleep apnea syndrome

background : sleep apnea is accompanied by some cardiovascular complications. it has even been hypothesized that sleep apnea, itself, can induce some of these complications. given such controversies, we assessed the left ventricular mass index (lvmi) and systolic pulmonary artery pressure in patients with sleep apnea. methods: through convenience sampling, 56 patients with the obstructive sleep...

Left ventricular diastolic dysfunction is linked to severity of obstructive sleep apnea Running head: diastole and sleep apnea

Word count: 199) Background Obstructive sleep apnea has been related to increased cardiovascular risk. The present study examined the relationships between respiratory parameters and left ventricular abnormalities in obstructive sleep apnea. Patients/Methods One hundred and fifty newly diagnosed OSA patients without any known cardiovascular disease were included (age = 49±11 years, BMI = 27.1±3...
