Death caused by Acute Coronary Syndrome (ACS) remains high because people do not have sufficient knowledge in interpreting the perceived sign and symptoms. This has an impact on the lack of people’s attitudes and belief in seeking health services. Providing information is a key factor in increasing knowledge, attitude, and belief toward ACS. This study aimed to determine the effect of health education on knowledge, attitudes, and belief about the acute coronary syndrome in Public Health Centre Tabanan III. This research implemented a pre-experimental design. There were 38 samples involved in this research, which were selected through purposive sampling. Health education was provided through 30 minutes’ presentation with the media of brochure and flyer. ACS Response Index questionnaire was used to collect the data. The method of data collection in this study was a self-completed questionnaire and analysed by using the Wilcoxon Signed Rank Test. Among 38 respondents, 55.3% were male. The median age was 37.2 years old. The result of the Wilcoxon Signed Rank Test showed there was a statistically significant increase in knowledge, attitudes, and belief after they were given health education. On the domain of knowledge, z = –5.40, p
