Plasma Amyloid β42 and Amyloid β40 Levels Are Associated With Early Cognitive Dysfunction After Cardiac Surgery

Decreased preoperative plasma levels of Aβ42 and Aβ40 in patients who exhibit postoperative cognitive dysfunction at 3 months suggest that postoperative cognitive dysfunction at this time may share a common mechanism with mild cognitive impairment and Alzheimer's disease. This process may be exacerbated by anesthesia.
