Abstract |
Cardiac surgery is one of the most commonly performed surgical procedures worldwide with >700,000 surgeries in 2006 in the US alone. Cardiac surgery results in a considerable exposure to physical and emotional stress; stress-related disorders such as depression or post-traumatic stress disorder are the most common adverse outcomes of cardiac surgery, seen in up to 20% of patients. Using information from a genome-wide association study to characterize genetic effects on emotional memory, we recently identified a single nucleotide polymorphism of the glucocorticoid receptor gene (the Bcll single nucleotide polymorphism) as a significant genetic risk factor for traumatic memories from cardiac surgery and symptoms of post-traumaticstress disorder. The Bcll high-risk genotype (Bcll GG) has a prevalence of 16.6% in patients undergoing cardiac surgery and is associated with increased glucocorticoid receptor signaling under stress. Concomitant animal experiments have confirmed an essential role of glucocorticoid receptor activation for traumatic memory formation during stressful experiences. Early cognitive behavioral intervention has been shown to prevent stress-related disorders after heart surgery. |
