Abstract:
BACKGROUND:Postinterventional cognitive dysfunction (PICD) is a known complication of coronary artery bypass grafting (CABG). However, it is largely unknown whether PICD occurs after coronary catheterization. METHODS:Neuropsychologic data were obtained from 37 patients who received coronary catheterization and 47 patients who underwent elective CABG at baseline and 3 months after the interventions. The outcomes were contrasted to 33 healthy volunteers, using analysis of covariance with baseline scores as covariates. Cerebral magnetic resonance imaging with diffusion-weighted imaging (DWI) sequences was performed in 30 catheter and 39 CABG patients 2 to 4 days after the procedures. RESULTS:The rate of acute ischemic lesions amounted to 3.3% in the catheter group and to 17.9% in the CABG group. Postinterventional cognitive dysfunction was detected in 2 (of 10) tests in the catheter group as compared with the healthy controls (verbal memory: total recall, t = -2.61 (P = .005) and nonverbal memory, t = -2.60 [P = .005]). The CABG group showed PICD in 7 of 10 tests as compared with the healthy controls (statistics ranging from t = -1.95 [P = .027] to t = -5.14 [P < .001]). Scores of depression/anxiety and health-related quality of life were not associated with PICD (P > .05). CONCLUSIONS:As compared with CABG, PICD and cerebral lesions appear to be substantially milder after coronary catheter intervention, but not negligible.
