Cardiovascular and Lifestyle Risk Factors and Cognitive Function in Patients With Stable Coronary Heart Disease

Background Vascular risk factors have been associated with differences in cognitive performance in epidemiological studies, but evidence in patients with coronary heart disease is more limited. Methods and Results The Montreal Cognitive Assessment score obtained 3.2±0.37 years after randomization to darapladib, a reversible inhibitor of lipoprotein phospholipase A2 or placebo was evaluated for 10 634 patients with coronary heart disease from 38 countries in the STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) trial. The Montreal Cognitive Assessment scores for darapladib and placebo groups were similar (mean±SD, 25.3±3.84 versus 25.4±3.73, respectively; P=0.27) and the adjusted odds ratio (OR) for mild cognitive impairment (Montreal Cognitive Assessment score <26) was 1.00 (95% CI, 0.93–1.09). Mild cognitive impairment was more likely with increasing age (OR, 1.33 [1.27–1.41], +5 years after 65). For other baseline clinical characteristics, the strongest independent ...
