Abstract
Recent researches have shown significant and persistent cognitive impairment in cardiac patients undergoing myocardial revascularization. At the same time, mild cognitive dysfunction, more amenable to prevention and correction, is less studied. For this reason, we aimed at analyizing the postoperative dynamics of cognitive functions, dependent on biomedical and psychosocial factors, of patients with CHD undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass, without clinically determined signs of dementia. Examination of fifty patients (of average age 57,4 ± 5,2 years) by psychodiagnostic methods (WAIS, TMT-test, Stroop test, TAS, Benton test, etc.) was effected in three stages: before CABG, before discharge, and three months after CABG. The results obtained demonstrate positive dynamics of nonverbal intelligence functions and negative dynamics of verbal functions during postoperative recovery, and also the correlation of the dynamics with clinical characteristics of patients. For instance, three months after CABG the level of visual memory increased (M ± m = 7,81 ± 0,48), whereas the level of short term verbal memory decreased (M ± m = 6,36 ± 0,57), as compared with the preoperative level (M ± m = 6,48 ± 0,25; M ± m = 8,18 ± 0,21, respectively, p <0,05). Upon rehabilitation, the indicators of psychomotor speed, attention switching, and cognitive flexibility, which were reduced at the first and second stages, have regained to the normal level. The data obtained can be helpful in developing rehabilitation programmes for patients undergoing CABG.
