[Cognitive dysfunction after coronary artery bypass grafting]

Area of Science:

• Cardiology
• Neurology
• Geriatrics

Background:

• Coronary artery bypass grafting (CABG) is increasingly performed in elderly patients with comorbidities.
• Neurological complications, notably postoperative cognitive dysfunction (POCD), persist despite surgical and anesthetic advances.
• Current prevention and rehabilitation strategies for POCD are insufficient.

Purpose of the Study:

• To explore the potential of physical training as a preventive and rehabilitative measure for POCD following CABG.
• To identify the mechanisms through which physical training might mitigate POCD.

Main Methods:

• The study reviews existing literature on CABG, POCD, and the physiological effects of physical training.
• Analysis focuses on mechanisms like endothelial dysfunction, systemic inflammatory response syndrome, and lipid peroxidation.

Main Results:

• Physical training demonstrates efficacy in addressing endothelial dysfunction.
• It also shows potential in correcting systemic inflammatory response syndrome and lipid peroxidation.
• These corrected mechanisms are implicated in the development and severity of POCD.

Conclusions:

• Physical training presents a safe and effective method for managing key pathophysiological mechanisms contributing to POCD after CABG.
• It offers a promising avenue for POCD rehabilitation in the context of cardiac surgery.
• Further research into structured physical training protocols for POCD is warranted.
