| Popis: | There is a dearth of evidence to characterize longitudinal changes in domain-specific cognitive function related to atrial fibrillation (AF).Methods and Results: This study enrolled 2,844 participants from the Systolic Blood Pressure Intervention Trial (SPRINT). Cognitive function was assessed at baseline and biennially during the follow-up period. Declines in global function and 4 major cognitive domains (i.e., memory, processing speed, language, and executive function) were fitted and compared between participants with and without AF using robust linear mixed-effect models. There were 252 participants with prevalent AF (mean [±SD] age 72.0±8.5 years; 30% women) and 2,592 participants without AF (mean age 67.9±8.4 years; 38% women). The annual decline in global function scores was greater among participants with than without AF (-0.016 vs. -0.012 points); however, the difference was not statistically significant (P=0.33). Processing speed declined faster in participants with prevalent AF, with a distinct difference of -0.013 points/year (95% CI -0.024~-0.001 points/year; P=0.02). For the memory, executive function, and language domains, there were no significant differences in the rate of cognitive decline between participants with and without AF.In this post hoc analysis of the SPRINT trial, processing speed was the most prominent cognitive domain affected by AF, which may be beneficial for the early screening of cognitive dysfunction. |
