Cognitive Function in Adults With Cardiac Disease

Study Summary

The purpose of this study is to identify cardiac patients' degree of unappreciated mild impairment in cognitive function patterns of cognitive function, and influencing factors related to cognitive functioning during hospitalization. The results from the study will contribute to tailoring the delivery of patient education to optimize patient understanding of information in future clinical practice. It is hypothesized that the study will demonstrate the following: 1. The degree of cognitive function for patients hospitalized in a CICU will be below the scores for normal functioning adults. 2. Patients with acute cardiovascular conditions will score differently in cognitive functioning at various times throughout their hospitalization. 3. Relationships between cognitive function and following variables: * Patients with greater sleep deprivation or fatigue will exhibit lower cognitive functioning. * Patients with greater hunger will exhibit lower cognitive functioning. * Patients who are experiencing greater anxiety will exhibit lower cognitive functioning. * Patients who are experiencing depression will exhibit lower cognitive functioning. * Patients who have undergone or will undergo shortly treatment or procedures will exhibit lower cognitive functioning.
