Cardiac surgery is commonly associated with brain ischemia. Few studies addressed brain electric activity changes after on-pump operations. Eyes closed EEG was performed in 22 patients (mean age: 45.2 ± 11.2) before and two weeks after valve replacement. Spouses of patients were invited to participate as controls. Generalized increase of beta power most(More)
Computer EEG is commonly used in longitudinal clinical studies though physiological changes of electrical brain activity during repeated EEG recordings are poorly known. Resting eyes-closed EEG was recorded twice in two weeks in 14 healthy subjects (13 women, aged 25-69 years). At follow-up, the significant decrease of alpha and theta-2 power, along with(More)
Background. Microemboli are a widely recognized etiological factor of cerebral complications in cardiac surgery patients. The present study was aimed to determine if size of left cardiac chambers relates to cerebral microembolic load in open heart operations. Methods. Thirty patients participated in the study. Echocardiography was performed in 2-3 days(More)
