Abstract

• This study was attempted to investigate the main factors affecting health perception of the patients following cardiac valve replacement surgery. Data were collected from Sept. 1 to Oct. 31, 1984 through administration of questionnaire developed for this study by the researcher. The subject was 95 patients who received follow up care following cardiac valve replacement surgery at S.N.U.H. The data were analyzed by T-test, oneway ANOVA, pearson correlation and multiple regression according to dependent variables. The results were as follows. (1) Average self-health perception of those patients were 4.62, (maximum;7 minimum;1) and they showed on affirmative response for their health condition. (2) There was significant difference in health perception according to sex difference. Men had higher health perception than women. (t=2.83, p=0.006) (3) There was significant difference in health perception according to occupation. Those who had occupation showed higher health perception those who had no occupation. (t=3.25, p=0.002) (4) The longer post-operative period elapsed, the higher health perception was, and there was significant difference in health perception. (gamma=-0.2958, p=0.002) (5) The higher age was, the lower health perception was, and there was a significant difference in health perception. (gamma=-0.2485, p=0.008) (6) The fewer subjective psychosomatic symptoms were, the higher health perception was, and there was a significant difference in health perception. (gamma=-0.4988, p=0.0000) (7) The more active daily activities were, the higher health perception was, and there was a significant difference in health perception. (gamma=0.6359, p=0.0000) (8) The main factors predicting health perception are like these. Daily activities (42.7%), highest variable. Psychosomatic symptoms (7.29%) Elapsed period after cardiac valve replacement (1,89%) Existence of occupation (1.87%) Sex (1.78%) Age (0.8%)
