Abstract

Background: Atrial fibrillation is associated with cognitive dysfunction. Atrial cardiomyopathy has been correlated with both entities. We aimed to characterize the association of echocardiographic parameters of atrial cardiomyopathy with cognitive function and cerebral changes.

Methods: Participants of the population-based Hamburg City Health Study underwent in-depth transthoracic echocardiography and cognitive function testing, the Animal Naming Test (ANT), the Trail Making Test A (TMT-A) and B (TMT-B), 10-word learning test and cerebral magnetic resonance imaging.

Results: After excluding individuals with stroke or depression, data from 7852 individuals were available. In multi-variable-adjusted regression analyses, the E/e'-ratio was associated with the level of impairment in the ANT (- 0.19 per one standard deviation [SD] increase, 95% confidence interval [CI] - 0.36-[- 0.01]) and the TMT-A (0.01 per one SD increase, 95% CI 0.003-0.020). Left atrial global peak strain was associated with positive performance in the TMT-A and B (-0.01 per one SD increase [95% CI - 0.02-(- 0.002)] and - 0.02 per one SD increase [95% CI - 0.03-(- 0.01)], respectively) and the immediate recall of the 10-word learning test (0.11 per one SD increase, 95% CI 0.02-0.20). The E/e'-ratio was positively associated with the total and periventricular white matter hyperintensity load in age- and sex-adjusted regression analyses though statistical significance was lost after multi-variable adjustment.

Conclusions: Subclinical echocardiographic signs of atrial cardiomyopathy and left ventricular diastolic dysfunction are associated with impaired performance in cognitive tests in the population. Our data provide evidence of the clinically important cardio-cerebral axis, relating cardiac dysfunction with cognitive performance.
