[A study on factors related to daily activities of post myocardial infarction patients].

The purpose of this study was to identify factors related to daily activities of post myocardial infarction patients. Data were collected from Aug. 1 to Aug. 31, 1988 through an interview schedule lasting for about 30-60 minutes by the investigators. Tools for this study were a daily activities scale and a subjective physical symptom scale developed by the researchers, and Zung's self rating depression scale. The subjects were 45 men 18 women post myocardial infarction patients who were receiving follow up care at SNU Hospital. The data were analyzed by percentage, mean, t-test, ANOVA, the Pearson moment Correlation Coefficient test, and Cronbach's a reliability test. The results were as follows. 1. Reliability of the daily activities scale was 0.91 by Cronbach's a. In the daily activities scale, items about transfer, exercise, and job related activities were most highly rated as meaningful to the post myocardial infarction patients. 2. The average daily activities score of these patients was 3.30 (maximum point:4) all scores were high except for exercise and job related activities. 3. There was a significant difference in daily activities according to sex; men had a higher daily activities score than women (T=2.32, P less than 0.05). 4. There was a significant difference in daily activities according to job status. Subjects having a job had a higher daily activities score. 5. The lower the depression score, the higher the daily activities score (gamma=-0.5748, P less than 0.05). 6. The lower the subjective physical symptoms score, the higher the daily activities score (gamma=-0.6015, P less than 0.05).
