Barbarash Medicina Alpha Rhythm Cognitive Dysfunction Coronary Artery Bypass Neurophysiological Tests Postoperative Cognitive Complications Introduction: This study aims to evaluate late postoperative neurophysiological outcomes in patients after coronary artery bypass grafting (CABG).Methods: Forty-five male patients with stable coronary artery disease aged 45-69 years underwent extended neuropsychological assessment using the software Status PF and electroencephalographical examination 3-5 days before CABG and 5-7 years after CABG. Postoperative decline in cognitive functions was determined by a 20% decrease in the cognitive indicator compared to that at baseline on 20% of the tests included in the Status PF battery. Statistical analysis was performed using the software STATISTICA 10.0. Multiple regression was used to identify demographic, clinical, and electroencephalographical variables associated with adverse cognitive outcomes.Results: Cognitive decline was observed in 54% of the patients in the long-term postoperative period. Five to seven years after CABG, all patients have shown an increase in the theta rhythm power compared to the preoperative values, which is most pronounced in the frontal and temporal areas of the right hemisphere (P=0.04), along with a decrease in the alpha rhythm in the posterior areas of the cortex (P=0.005). Multiple regression has reported that the main predictors of cognitive impairment are slower mean alpha frequency, decreased theta-2 rhythm with eyes closed in the right temporal area, and increased theta-2 rhythm with eyes open in the left temporal area (F(5.39)=8.81; P<0.00007; adjusted R-squared=0.57).Conclusion: Our findings indicate that 54% of the patients suffer from postoperative cognitive decline associated with increased theta and decreased alpha rhythms 5-7 years after CABG. 2021 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398969709019 https://www.redalyc.org/journal/3989/398969709019/ https://www.redalyc.org/journal/3989/398969709019/html/ https://www.redalyc.org/journal/3989/398969709019/398969709019.epub https://www.redalyc.org/journal/3989/398969709019/movil 10.21470/1678-9741-2020-0390 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.5 Vol.36 |
