Quality of life post-myocardial infarction: effects of a transtelephonic coronary intervention system.
The impact of an outpatient, risk-management system, including a transtelephonic electrocardiographic monitor and lidocaine injector, on the quality of life in post-myocardial infarction patients was examined. Patients (n = 238) were assigned randomly to either the system or to standard medical care (control). Quality of life was defined in terms of psychological status, return to work, and social functioning. Relative to control patients, system patients showed a significant decrease in concerns about physical functioning and symptoms, and, over time, reported less depressive affect. At 9-month follow-up, control patients were more than twice as likely to be in the range of clinical depression. Patients' perceptions of their ability to manage a recurrence of cardiac symptoms appeared to be related inversely to depressive affect. Moreover, a larger percentage of system patients (92%) had returned to work by the 9-month follow-up, compared with control patients (76%). There were, however, no significant differences between groups in the degree of impairment in social interaction. Overall, these results indicate that the use of a "system" encouraging patient participation in treatment can significantly improve qualify of life after a myocardial infarction.
