Aim The purpose of the current study is to ascertain how educational intervention affects cardiovascular disease prevention. Methods The current investigation is a quasi-experimental study conducted in Shiraz, Iran, in the year 2022, focusing on 200 hypertension patients (by sample random sampling) that were divided into two groups: a control group consisting of 100 participants (63 males and 37 females) and an intervention group also consisting of 100 participants (58 males and 42 females). The data collection instrument comprises inquiries pertaining to demographic factors as well as constructs of the health belief model (HBM) and preventive behaviours for cardiovascular diseases. The participants in both groups completed the questionnaire prior to and three months after the intervention. The intervention group underwent a total of six training sessions, each lasting 55 min. Results The results showed that after the intervention, the intervention group showed a significant increase in all cues of the HBM model except for the perceived barriers. Following a period of three months subsequent to the educational intervention, the experimental group also exhibited a notable reduction in blood pressure in comparison to the control group. Conclusion The findings of the study indicate that the utilisation of the HBM demonstrated positive outcomes in facilitating the promotion of cardiovascular disease prevention among patients diagnosed with hypertension. The promotion of health among individuals with high blood pressure can be both beneficial and feasible. Moreover, this particular model can be utilised as a comprehensive framework for the development, execution, and evaluation of advantageous and effective healthcare initiatives.","PeriodicalId":30457,"journal":{"name":"JRSM Cardiovascular Disease","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135507772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
