Our Summary

This study looked at whether computerized cognitive training (CCT) could help older adults undergoing heart bypass surgery to improve their cognitive abilities, including reducing incidences of delirium, both before and after the surgery. The study had 36 participants, half of whom took part in the CCT, while the other half had the usual care plus weekly phone calls. The training was done before the surgery and started again one month after the surgery. The training involved sessions that lasted between 45 to 60 minutes.

The researchers found that most of the participants stuck to the CCT program. However, they didn’t find any significant improvement on the cognitive abilities of the participants or a reduction in delirium cases.

The researchers believe that the lack of significant results could be due to the small size of the study, which was affected by the COVID-19 pandemic. They also suggest that a combination of different interventions might be more effective. However, they conclude that implementing CCT for patients undergoing heart bypass surgery is feasible.

Doctor’s Tip

One helpful tip a doctor might tell a patient about CABG is to discuss the possibility of incorporating cognitive training as part of their recovery plan. While this particular study did not show significant improvements, it is still worth considering as part of a comprehensive approach to improving cognitive abilities and reducing the risk of delirium after surgery. It is important to consult with your healthcare provider to determine the best course of action for your individual needs.

Suitable For

Patients who are typically recommended for coronary artery bypass grafting (CABG) include those with severe coronary artery disease that cannot be managed effectively with medication or other less invasive procedures. This includes patients with:

  • Severe blockages in multiple coronary arteries
  • Left main coronary artery disease
  • Severe chest pain (angina) that is not relieved by medications
  • High risk of heart attack or other cardiac events
  • Previous heart attack or heart failure
  • Diabetes with coronary artery disease

It is important to note that each patient is unique, and the decision to undergo CABG is individualized based on the patient’s specific medical history, symptoms, and overall health.

Timeline

Before CABG:

  1. Patient is diagnosed with coronary artery disease and recommended for CABG surgery.
  2. Patient undergoes preoperative testing and preparation for surgery.
  3. Patient may receive counseling and education on the procedure and postoperative care.

After CABG:

  1. Patient undergoes CABG surgery, which involves rerouting blood flow around blocked or narrowed arteries in the heart.
  2. Patient is monitored closely in the intensive care unit immediately after surgery.
  3. Patient is transferred to a regular hospital room for further recovery.
  4. Patient undergoes cardiac rehabilitation to improve physical and cardiovascular health.
  5. Patient may experience cognitive changes, including the potential for delirium.
  6. Some patients may undergo cognitive training to improve cognitive abilities post-surgery.
  7. Patient continues to be monitored for long-term outcomes and potential complications.

Overall, the timeline includes preoperative preparation, surgery, immediate postoperative care, rehabilitation, and long-term monitoring and care for patients undergoing CABG surgery.

What to Ask Your Doctor

  1. Can computerized cognitive training (CCT) help improve my cognitive abilities before and after my heart bypass surgery?
  2. How long and how often would I need to participate in CCT sessions?
  3. What are the potential risks or side effects of participating in CCT?
  4. Are there any other interventions or treatments that could be combined with CCT to potentially improve cognitive abilities and reduce the risk of delirium after surgery?
  5. What are the potential limitations of a small study size in determining the effectiveness of CCT in this population?
  6. How feasible would it be for me to participate in a CCT program before and after my heart bypass surgery?
  7. Are there any other cognitive training programs or interventions that may be more effective for improving cognitive abilities in older adults undergoing heart bypass surgery?
