The effects of a nutrition program on knowledge and behavior after balloon angioplasty at Banpong Hospital, Ratchaburi Province.

Abstract

      This quasi experimental research aimed to investigate the effects of a nutritional program on knowledge and dietary behavior among patients with coronary artery disease after percutaneous coronary intervention. The sample consisted of 35 patients who had undergone coronary artery dilation. Participants were selected using simple random sampling. The research instruments included a demographic data questionnaire, a nutritional knowledge questionnaire for patients with coronary artery disease, and an interview form regarding dietary behavior for prevention of recurrent coronary artery stenosis. Data were analyzed using frequency, percentage, mean, standard deviation, and paired t-test.

      The results revealed that after participating in the nutritional program, patients demonstrated improved knowledge regarding appropriate nutrition for coronary artery disease. Before participation, most patients had a high level of knowledge (68.57%), which increased to 97.14% after the program. The mean knowledge score significantly increased from 18.43 ± 2.51 to 23.66 ± 1.08 (p = 0.001). Regarding dietary behavior, before participation, most patients demonstrated moderate dietary behavior (77.14%), whereas after participation, most patients improved to a good level of dietary behavior (82.86%). The mean dietary behavior score significantly increased from 26.17 ± 2.64 to 31.83 ± 2.41 (p = 0.001).
