Abstract P312: High State and Trait Hopelessness Levels Predict Lower Home-based Exercise Participation in Patients With Coronary Heart Disease

Abstract

Introduction: Hopelessness is associated with increased adverse events and decreased survival in patients with coronary heart disease (CHD). Hopelessness can persist in these patients and reduce their participation in hospital-based cardiac rehabilitation (CR) exercise following an acute event. Because the majority of CHD patients do not attend a hospital-based CR exercise program, examination of factors affecting home exercise is needed. The purpose of this study was to describe the impact of hopelessness levels on both home- and hospital based CR exercise participation in patients with CHD. Hypothesis: It was hypothesized that higher state and trait hopelessness levels would adversely affect both home- and hospital-based CR exercise participation. Methods: The Theory of Hopelessness Depression was used as a foundation for study aims. Using a descriptive, longitudinal design, 282 patients who had been hospitalized with a CHD event were asked to complete the State-Trait Hopelessness Scale (STHS) during their hospitalization and the STHS and the Cardiac Rehabilitation Exercise Participation Questionnaire at 3, 8, and 12 months after hospital discharge. Patients who provided data at any two concurrent time points over the year were included in the analyses. Regular exercise was defined as walking or biking ≥3 days/week in a home- or hospital-based Phase II CR exercise program. Logistic regression was used to evaluate the relationship between STHS scores on the likelihood that patients would participate in regular exercise in home- or hospital-based Phase II CR settings. Results: Patients were predominantly male (64.9%) with a mean age of 65.4±9.7 years. Patients had persistent, modest levels of state and trait hopelessness across all time points. High levels of state and trait hopelessness were predictive of lower home-based exercise participation (state: OR 0.4, 95% CI [0.1, 0.7], p=0.002; trait: OR 0.4, 95% CI [0.2, 0.8], p=0.01) but not hospital-based Phase II CR exercise, after adjusting for age and sex. Conclusions: These findings demonstrate the importance of assessing hopelessness in patients with CHD and provide critical evidence of the need for clinicians to encourage CHD patients who are feeling hopeless to participate in CR exercise, particularly in the home setting.
