The effects of education and group discussion in the post myocardial infarction patient.

An education and group discussion program administered to a randomly selected group of post myocardial infarction subjects failed to produce any differences in a large number of behavioral and psychological measures. These included smoking behavior, health status, social and recreational status, family and marital life and vocational activities, as well as measures of anxiety, depression, and health locus of control. Treated subjects were slower to return to work than controls and were less likely to have returned to work by the end of the study. More individuals in the treatment group were receiving compensation and this may have been a factor in delaying return to work. Since the majority of our subjects had a very optimistic attitude toward their eventual recovery, there was limited room for improvement. We suggest that cardiac rehabilitation be directed only at those patients with "negative" attitudes, and with more than usual anxiety and depression.
