Abstract 19105: Predictors of Poor Functional Status One Year Following Cardiac Rehabilitation
Introduction: Functional status is known to significantly improve after participating in cardiac rehabilitation. However, even when participants adhere to rehabilitation, many individuals do not improve in their ability to perform everyday activities such as walking. The purpose of this study was to explore predictors of poor functional status in participants who participated in a cardiac rehabilitation program and 12-month cognitive-behavioral intervention study designed to support behavior change.
Methods: Using a study arm database, a secondary analysis was performed on the 25% of participants with the lowest six-minute walk test scores (N=73). Walk scores ranged from 80 feet to 996 feet walked in six minutes. Linear regression was used to predict total feet walked during the six-minute walk. Study arm was controlled for in the analysis. Age, gender, Charlson comorbidity index score, weight, New York Heart Association (NYHA) Class, and total number of exercise hours reported were considered as potential predictors. The sample mean age was 72.6 years old (SD=7.8, Range=56-89). The sample consisted of 51% men, 49% women, 86% Caucasian, and 14% minority. The majority of the sample was NYHA Class I (74%). Class II made up 14%, Class III made up 11%, and Class IV was 1% of the sample.
Results: Predictors of poor functional status were age (β=-.343; p<.01), gender (β=.338; p<.01), weight (β=-.308, p<.05), and NYHA class (β=-.277; p<.05). Comorbidity score and total number of exercise hours reported were not found to be predictors of poor functional status.
Conclusions: Findings indicated that as age increased, functional status decreased. Similarly as weight increased, functional status decreased. Men were found to have better functional status than women. Furthermore, as NYHA class increased, functional status decreased. Interestingly, comorbidity score and total number of exercise hours reported were not a predictor of functional status. Study arm had no impact on functional status in regard to these variables. Further exploration of these predictors are needed to improve functional status in older patients with cardiac disease.
