Evaluation of subclinical right ventricular dysfunction in obstructive sleep apnea patients using velocity vector imaging.
BACKGROUND The aims of this study were to evaluate subclinical regional right ventricular (RV) dysfunction in newly diagnosed obstructive sleep apnea (OSA) patients without systemic and pulmonary arterial (PA) hypertension, and to correlate OSA severity to RV dysfunction, using both velocity vector imaging (VVI)-derived strain imaging and tissue Doppler imaging (TDI). METHODS AND RESULTS The ...
متن کاملAssessment of regional right ventricular systolic function in patients with obstructive sleep apnea syndrome using velocity vector imaging
Obstructive sleep apnea syndrome (OSAS) is the most common type of sleep disorder which is associated with a series of cardiovascular disorders, including right ventricular (RV) dysfunction. However, it is difficult to assess the RV function systematically using a conventional echocardiography because RV has a complex geometrical shape. A case-control study was performed to assess the regional ...
متن کاملExecutive dysfunction in patients with obstructive sleep apnea syndrome.
AIMS To clarify whether patients with obstructive sleep apnea syndrome (OSAS) have executive dysfunction, to identify the domains of executive function affected and to establish the severity of any dysfunction. METHODS A full-night polysomnography and a comprehensive neuropsychological assessment focusing on executive functions were conducted on 40 newly diagnosed OSAS patients and 20 healthy...
متن کاملRight ventricular dysfunction in patients with obstructive sleep apnoea syndrome.
There is conclusive evidence that obstructive sleep apnoea syndrome (OSAS) influences right heart haemodynamics and can also induce pulmonary hypertension. It is not known, however, whether right ventricular dysfunction can occur in patients with OSAS in the absence of lung disease. We studied 107 patients (94 males, 13 females, mean age 55 +/- 11 yrs) with polysomnographically verified OSAS in...
متن کاملApert Syndrome with Obstructive Sleep Apnea: A Case Report
Apert syndrome is a rare kind of craniosynostosis which is identified with fusion of cranial sutures during prematurity period and causes physical and intellectual disorders in younger ages. These patients may show symptoms of obstructive sleep apnea due to abnormal craniofacial shape. This article introduces a patient with Apert syndrome, with apnea symptoms, cyanosis, snoring, restlessness, n...
