Cardiac function and cognitive function in patients with obstructive sleep apnea

Abstract Objectives This study was designed to evaluate echocardiographic findings in patients with obstructive sleep apnea (OSA) cognitive impairment and compare it the control group. Methods Sixty-seven OSA 52 group of healthy controls were evaluated prospectively by Mini-Mental State Examination questionnaire trans-thoracic echocardiography. Results The diastolic dysfunction 19.6% ( P = .002) 18.4% .016) more prevalent compared mean tricuspid regurgitant gradient, pulmonary artery size, transmitral A velocity higher, but right ventricular peak systolic velocity, annular plane excursion (TAPSE), fractional area change (FAC), E/A ratio, E’ lower than Comparing without disorders, showed significant differences regarding size atrium, TAPSE FAC < .05). Conclusions need accurate cardiac examinations, early diagnosis, interventions prevent progression dysfunction, especially older male higher BMI impaired cognition. Further studies are needed determine exact link between OSA, obesity, physiology.
