Subclinical Left Ventricular Dysfunction in Patients with Obstructive Sleep Apnea
OBJECTIVE We aimed to investigate whether fragmented QRS (fQRS) is associated with subclinical left ventricular (LV) dysfunction in patients with obstructive sleep apnea (OSA). SUBJECTS AND METHODS A total of 141 patients with OSA who had normal LV ejection fraction (LVEF) were included in the study. The fQRS was defined as the presence of an additional R wave, notching of R or S wave or the ...
متن کاملCentral sleep apnea in left ventricular dysfunction: prevalence and implications for arrhythmic risk.
BACKGROUND The prevalence and characteristics of sleep-disordered breathing in patients with asymptomatic left ventricular (LV) dysfunction are unknown. Therefore, we evaluated the prevalence of sleep-disordered breathing in patients with LV dysfunction without overt heart failure and tested the hypothesis that sleep-disordered breathing is linked to greater hemodynamic and autonomic impairment...
متن کاملLeft 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...
متن کاملLeft ventricular systolic dysfunction in patients with obstructive sleep apnea syndrome.
STUDY OBJECTIVES Conflicting results have been reported regarding the effects of obstructive sleep apnea syndrome (OSAS) on daytime left ventricular (LV) systolic function. This study aimed to assess the prevalence and causes of LV systolic dysfunction, using radionuclide angiography, in a large group of patients with OSAS. DESIGN AND SETTING A prospective study in the pneumology department o...
متن کاملHigh myocardial 18F-FDG uptake after chemotherapy in the presence of left ventricular dysfunction as well as 3-month later with no left ventricular dysfunction
Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...
