Background Coronary artery bypass graft (CABG) surgery has been found to be associated with post-operative cognitive decline. Despite the large and growing numbers being conducted in South Africa, the associated or ensuing cognitive symptoms or impairment have received little research attention. Aim The aim of this pilot study was to describe the nature and extent of subjective cognitive complaints (SCCs) and objective cognitive impairments in patients 6-week post-CABG surgery in a clinical sample in KwaZulu-Natal (KZN) Province, South Africa. Setting A cross-sectional survey was conducted among outpatients attending their 6-week post-CABG surgical review at a cardiology clinic in a KZN provincial hospital. Method Socio-demographic and clinical data were captured, with SCCs being determined by using standardised questions; cognition was assessed with the Montreal cognitive assessment (MoCA). Results The mean age of the sample (n = 28) was 58.72 years. The mean MoCA score was 23.96 (SD = 4.32); 60.71% (n = 17) screening positive (< 25/30) and more likely to be older, male, hypertensive and diabetic. A third (n = 9; 35.71%) reported at least one new SCC; their mean age was 55.36 years which was lower than those without subjective complaints (59.81). Conclusions Subjective and objective cognitive impairments were evident in patients 6-week post-CABG surgery identifying a need for longitudinal cognitive screening both pre- and post- operatively in patients undergoing CABG surgery.

冠状动脉旁路移植术后 6 周的主观和客观认知：一项描述性试验研究。

背景 已发现冠状动脉旁路移植术 (CABG) 手术与术后认知能力下降有关。尽管在南非进行了大量且不断增长的研究，但相关或随之而来的认知症状或损害几乎没有受到研究关注。目的 本试验性研究的目的是在南非夸祖鲁-纳塔尔省 (KZN) 省的临床样本中描述 CABG 手术后 6 周患者主观认知主诉 (SCC) 和客观认知障碍的性质和程度。设置 在 KZN 省级医院的心脏病科门诊就诊的 CABG 术后 6 周手术复查的门诊患者中进行了一项横断面调查。方法 收集社会人口统计学和临床​​数据，使用标准化问题确定 SCC；认知评估采用蒙特利尔认知评估（MoCA）。结果样本的平均年龄（n = 28）为58.72岁。平均 MoCA 得分为 23.96 (SD = 4.32)；60.71% (n = 17) 筛查阳性 (< 25/30) 并且更有可能是老年人、男性、高血压和糖尿病患者。三分之一（n = 9；35.71%）报告了至少一个新的 SCC；平均年龄55.36岁，低于无主观主诉者（59.81）。结论 CABG 手术后 6 周患者的主观和客观认知障碍很明显，这表明需要在接受 CABG 手术的患者术前和术后进行纵向认知筛查。25/30)，更有可能是老年人、男性、高血压和糖尿病患者。三分之一（n = 9；35.71%）报告了至少一个新的 SCC；平均年龄55.36岁，低于无主观主诉者（59.81）。结论 CABG 手术后 6 周患者的主观和客观认知障碍很明显，这表明需要在接受 CABG 手术的患者术前和术后进行纵向认知筛查。25/30)，更有可能是老年人、男性、高血压和糖尿病患者。三分之一（n = 9；35.71%）报告了至少一个新的 SCC；平均年龄55.36岁，低于无主观主诉者（59.81）。结论 CABG 手术后 6 周患者的主观和客观认知障碍很明显，这表明需要在接受 CABG 手术的患者术前和术后进行纵向认知筛查。
