Cognitive training to prevent cognitive decline after heart surgery

Increasing Preoperative Cognitive Reserve to Prevent Postoperative Delirium and Postoperative Cognitive Decline in Cardiac Surgical Patients. A Randomized Controlled Trial on Cognitive Training

Not applicable Interventional Heart and Brain Research Group, Germany · NCT04493996

This study is testing if doing brain exercises before heart surgery can help prevent memory problems and confusion after the surgery for patients undergoing elective cardiac procedures.

What this trial studies

This study aims to prevent postoperative cognitive dysfunction in patients undergoing elective cardiac surgery by enhancing their cognitive reserve through preoperative cognitive training. It is a randomized controlled trial involving 100 patients who will either participate in a home-based cognitive training program or serve as a control group without any intervention. The cognitive training consists of standardized paper-and-pencil exercises performed for about 40 minutes daily over a period of 2-3 weeks before surgery. The study will assess the impact of this training on the incidence of postoperative delirium and cognitive decline during hospitalization and at follow-up three months post-surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for elective cardiac surgery who have a good understanding of the German language.

Not a fit: Patients with a history of stroke or preexisting psychiatric or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of cognitive decline and delirium in cardiac surgery patients, improving their postoperative recovery and quality of life.

How similar studies have performed: Other studies have shown promising results with cognitive training interventions in similar patient populations, suggesting potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

* Elective cardiac surgery (coronary artery bypass surgery, aortic or mitral valve replacement/reconstruction, or combination surgery) with standardized extracorporeal circulation
* A sufficiently good knowledge of German is necessary as cognitive training and neuropsychological tests are language-dependent

Exclusion Criteria:

* History of stroke and preexisting psychiatric or neurological disorders that may impair the neuropsychological performance
