Researchers have used cognitive psychology paradigms to evaluate emotional sequela of cardiovascular disease, although there have been no prior studies assessing implicit memory bias in a population of patients with cardiac problems. The purpose of the present investigation was to assess whether cardiac events precipitate disease-specific information processing changes in implicit memory. Results provided very limited support for a cardiac-specific memory bias, using a measure of conceptual implicit memory. A trend for patients with cardiac problems to rate white noise surrounding cardiac words as less loud, indication of an implicit memory bias, was present only at one white noise level evaluated, t(15) = −1.91, p = .08. Despite limited evidence for a cardiac-specific threat schema, further investigation appears warranted. Information processing paradigms adapted from cognitive psychology offer an alternative to experimental approaches entirely dependent on participant self-report.
