Summary

This trial is testing if giving insulin through the nose can help older patients and those having major heart surgery avoid memory and thinking problems after their operation. The idea is that insulin might protect the brain and improve its function. Insulin administered this way has shown potential in improving cognitive function and reducing side effects by directly affecting the brain.

Who is the study for?
This trial is for adults scheduled for elective open heart surgery with cardiopulmonary bypass. Participants must be able to consent, speak English or French, and not have any sensory impairments that affect cognitive testing. It's not suitable for those allergic to insulin or pregnant individuals.
What is being tested?
The study tests if intranasal insulin can improve memory and cognition after heart surgery, aiming to reduce Postoperative Cognitive Dysfunction (POCD) and Delirium (POD). Patients will receive regular human insulin or a saline solution as a comparison.
What are the potential side effects?
Intranasal insulin may cause local irritation in the nose, low blood sugar levels if absorbed systemically, headache, runny nose, or cough. However, since it's administered nasally rather than injected into the bloodstream directly, systemic side effects are expected to be minimal.

Other Research
Common treatments for heart disease include beta-blockers, ACE inhibitors, statins, and antiplatelet agents. Beta-blockers reduce heart rate and blood pressure by blocking adrenaline effects, ACE inhibitors relax blood vessels by inhibiting the angiotensin-converting enzyme, statins lower cholesterol by inhibiting HMG-CoA reductase, and antiplatelet agents prevent blood clots by inhibiting platelet aggregation. These treatments are crucial for heart disease patients as they help manage symptoms, prevent complications, and improve overall cardiovascular health. Similar to intranasal insulin, which improves cognitive function, these treatments can also have secondary benefits, such as reducing the risk of stroke and improving quality of life.
