PURPOSE. The purpose of this study is to test a multicomponent model examining the relationship between estrogen replacement therapy (ERT) use with angina, daily physical activity, and quality of life in postmenopausal cardiac women. RATIONALE. Evaluation of the impact of ERT in the overall energy expenditure of postmenopausal cardiac women is intended to provide some understanding and/or explanation to the hypothesis that estrogen has vasoactive effects on coronary circulation that impact the physical activity and exercise tolerance of postmenopausal cardiac women. DESIGN. This is a prospective, comparative, and cohort study of approximately 180 postmenopausal women enrolled in cardiac rehabilitation (CR) at three CR centers in Northeastern Ohio. Data will be obtained from patient interviews, medical record review, self-report questionnaires, and electronic physical activity monitor. Cardiac women receiving ERT and those women not receiving ERT will be enrolled in the study simultaneously until the targeted number of 90 subjects per group is recruited. Multiple measures will be used for each construct in the model: estrogen use (type, duration, and compliance), physical activity (intensity and energy expenditure), angina (frequency and severity), and quality of life (mental and physical components). STATISTICS. Structural equation modeling using LISREL will be employed to estimate and evaluate the system of hypotheses proposed by the model. The model includes 13 parameters and 4 latent variables. IMPLICATIONS. Studies on the relationship of estrogen and daily physical activity in cardiac women are not available. Estrogen's demonstrated impact on coronary circulation may provide an additional rationale for the prudent use of ERT as an adjunct in secondary prevention efforts for coronary artery disease. This study will also be useful in identifying directions for future research and if the model is supported, its utility will be confirmed in a future study. AN: MN030154
