Abstract
This study aimed to analyze of the structure and frequency of detection of cognitive decline in patients undergoing on-pump coronary artery bypass grafting (CABG). It was found that the development of early postoperative cognitive dysfunction (POCD) was observed in 62% patients 7–10 days after CABG. Long-term POCD was detected in 56% cases1 year after CABG. The early POCD structure consisted of cognitive decline with combination of two domains (neurodynamic and memory) more often – 31.3% cases, less – three domains (neurodynamic, memory and attention) – 13.7%. The cognitive decline in one domain was found the most frequently in neurodynamic (23.7%). In the structure of the long-term POCD the changes in cognitive functions identified in the early postoperative period was saved, the combination of two domains (neurodynamic and memory) was found the most frequently – in 31.3% cases. In addition, a one year after CABG increased the number of patients with neurodynamic disorders to 27.5% and with cognitive decline in three domains (neurodynamic, memory and attention) to 19.3%. Results of the study showed that the cognitive status of patients deteriorates one-year followup after on-pump CABG.
