Background Cognitive impairment is a phenomenon that appears late in many diseases. Many clinicians do not seriously consider cognitive impairment until there has been significant deterioration over time. Cognitive function can be assessed using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Methods Using an observational case-control study design, we examined the relationship between coronary artery disease (CAD) and cognitive impairment. Participants (57 patients with CAD and 60 healthy controls; age: 30-60 years) were recruited and sampled using a non-probability quota sampling technique. Self-administered questionnaires were used to collect data about participants' demographic information. Blood chemistry samples were obtained to evaluate patients for CAD. Mini-Mental State Examination (MMSE) and CANTAB using three subsets including intra-extra dimensional set shift, spatial span (SSP), and pattern recognition memory (PRM) were used to assess participants' cognitive function. Results The SSP and PRM were significantly lower in patients with CAD as compared with healthy controls. There were significant relationships of PRM with creatine kinase- muscle/brain, aspartate aminotransferase, and total cholesterol. On the other hand, SSP was found to have a significant relationship with triglycerides. Conclusion There is cognitive impairment in CAD patients that needs to be assessed for early interventions to maintain cognitive functions.
