Examining the Dominant Factors Affecting Smoking Cessation in Patients with Coronary Heart Disease

Abstract

Background: Smoking poses a significant public health issue and is a major risk factor for cardiovascular diseases, especially coronary heart disease (CHD). Effective smoking cessation strategies are crucial for improving health outcomes in patients with CHD. Objective: This study aims to identify factors influencing smoking cessation compliance in CHD patients, focusing on family support, environmental support, knowledge, and perception. A cross-sectional study was conducted at Mitra Medika Amplas Hospital, Medan, Indonesia, involving 100 participants from June to December 2022. Methods: Data were collected using structured questionnaires. Bivariate and multivariate statistical analyses, including logistic regression, assessed the relationships between the variables and smoking cessation compliance. Results: Family support significantly predicted smoking cessation compliance, with an odds ratio of 16.454 (P=0.044). While environmental support, knowledge, and perception showed significant associations in the bivariate analysis, multivariate analysis revealed these factors were not independent predictors when adjusted for other variables. Thus, family support remains the dominant factor influencing successful cessation. Conclussion: The findings underscore the critical role of family support in smoking cessation among CHD patients. Although environmental support, knowledge, and perception are related to compliance, they do not have the same level of impact. Enhancing family involvement may improve cessation rates, offering valuable insights for healthcare providers in Indonesia.
