“…Coronary heart disease, diabetes, hypertension, cholesterol, general health status, heart failure, duration of AFIB, and education were unrelated to neuropsychologic test performance and, thus, were not used as statistical controls. Our study differs in several respects from the study of Park et al 31 Foremost among these differences is that we did not use a case-control study with patient volunteers and did not restrict our study to older adults. We used a community-based sample with a large non-AFIB referent group and our patients ranged in age from 37 to 89 years at neuropsychologic testing.…”
