Each year, 1.1 million Americans experience acute myocardial infarction (AMI). Diminished heart rate variability (HRV) has been identified as one of the best predictors of morbidity and mortality in this group. Another major determinant of negative outcomes is the extent of myocardial damage, which is influenced by factors impacting myocardial oxygen (MVO2) supply and demand. Increased sympathetic nervous system activity, resulting from multiple psychological and physiological stressors, can substantially increase MVO2 demand. Previous research has shown that music therapy reduces anxiety and MVO2 demand, while it increases HRV. However, intervention issues including optimal time of day and frequency of music delivery have not been tested. The purpose of this randomized six-group experimental design study is to compare effectiveness of music therapy for improving indicators of cardiac autonomic nervous system function and reducing anxiety. The six comparison groups are (1) music once per day (morning); (2 & 3) music twice per day (morning & afternoon; morning & evening); (4) music three times per day (morning, afternoon, & evening); (5) attention (quiet rest); and (6) control (usual treatment). The conceptual framework guiding this study is based on previous work in the areas of stress, relaxation response, music therapy, and physiological theory. Approximately 100 of the 180 subjects have been enrolled. All have experienced AMI during the previous 72 hours. Dependent variables include heart rate, respiratory rate, blood pressure, MVO2 demand, HRV, and state anxiety. Repeated measures MANOVA will be used to compare both pre- and post-intervention measures of the dependent variables. Contrasts of 24-hour summary HRV data also will be completed. Findings will provide preliminary empirical evidence for optimal frequency and time of day for implementing music sessions during acute recovery from MI.
