Abstract:
OBJECTIVETo analyze the risk factors of cognitive impairment after off-pump coronary artery bypass grafting (OPCABG).
METHODSA total of 102 patients [male: 82, age: (65.7 ± 7.1) years] undergoing OPCABG in our hospital between January 2009 and December 2010 were divided into postoperative cognitive dysfunction (POCD) group and non-POCD group by the MMSE questionnaire survey conducted at 7 days pre- and post-operation respectively.
RESULTSThe incidence of POCD was 48.0% (49/102). Multivariate logistic stepwise regression analysis showed: advanced age (OR = 1.32, 95%CI: 1.10 - 1.46, P = 0.002), smoking (OR = 1.26, 95%CI: 1.18 - 1.32, P = 0.001), hypertension (OR = 1.66, 95%CI: 1.36 - 1.78, P = 0.023), diabetes (OR = 1.62, 95%CI: 1.02 - 2.84, P = 0.032), stroke (OR = 3.32, 95%CI: 1.68 - 6.49, P < 0.001), mitral regurgitation (OR = 1.48, 95%CI: 1.26 - 1.89, P < 0.001), and time of wall clamp (OR = 4.84, 95%CI: 1.08 - 7.28, P < 0.001) were independent risk factors of POCD.
CONCLUSIONAdvanced age, smoking, hypertension, diabetes, stroke, mitral regurgitation, and prolonged time of wall clamp are major risk factors for POCD in patients undergoing OPCABG.
