Abstract
Background: Ischemic heart disease (IHD) is a significant health concern globally, with various risk factors affecting the outcomes of therapeutic interventions like percutaneous coronary interventions (PCIs) and coronary artery bypass grafting (CABG). The use of smokeless tobacco products such as SLT (snus, loose snuff) and Naswar is prevalent in South Asia and poses additional risks due to its cardiovascular implications.
Objective: This study aims to assess the impact of smokeless tobacco (SLT/Naswar) use on the incidence of IHD following coronary interventions, highlighting the need for tailored healthcare strategies to address this modifiable risk factor.
Methods: A prospective observational study was conducted from July 1, 2023, to January 1, 2024, involving 200 participants aged 18 to 80 years diagnosed with IHD. Data collection involved structured interviews and comprehensive reviews of health records. Statistical analyses included Chi-square tests and logistic regression to evaluate the association between SLT/Naswar usage and IHD incidence post-intervention, with SPSS software utilized for all computations.
Results: Among the participants, 40.5% were users of SLT/Naswar. Post-coronary intervention, SLT/Naswar users showed a 66% incidence rate of IHD compared to 48% in non-users, with a statistically significant difference (P=0.032). Successful intervention rates were 62% in SLT/Naswar users versus 78% in non-users. Complication rates such as re-stenosis were higher in SLT/Naswar users (29% vs. 16%).
Conclusion: The study demonstrates that SLT/Naswar use significantly impacts the outcomes of coronary interventions, with a higher incidence of IHD and complications among users. These findings underscore the importance of integrating smokeless tobacco cessation programs into cardiovascular care protocols.
