Objective
Coronary angiography (CAG) is the gold standart technique in diagnosing coronary artery disease (CAD). However contrast agents used for coronary angiography may lead to some contrast induced complications. In this study we aimed to compare electroencephalographies of patients before and after angiography.
Methods
Fifty patients who were referred to rutine coronary angiography for suspected CAD were included in this study. Electroencephalography (EEG) was performed to each patient before CAG and 30 minutes and 12 hours after CAG. Contrast dose was recorded for each patient. Pre- and post-CAG EEG’s were compared regarding pathological wave activation.
