Predictive value of neuropsychological assessment; with regards to life expectancy among cardiac bypass surgery patients
This follow-up study to Keith et al. (2002) sought to explore relations between the cognitive, neuropsychological, and psychosocial sequelae of cardiopulmonary bypass surgery (CPB) and survival. A neuropsychological test battery including the state portion of the State-Trait Anxiety Inventory (S-STAI), reaction time, visual attention (VFA), rotor pursuit, visual spatial memory, verbal memory and paired associations (PA) was administered. PA (P < .05), VFA and S-STAI scores were related with 5–7 year survival. After the Benjamini-Hochberg method was employed to control for multiple comparisons only S-STAI scores remained significant. Results of logistic regression indicate that pre-CPB surgery scores on the S-STAI accurately predicted 5–7 year survival and mortality in 66% and 83% of cases respectively.
