Risk of acute coronary syndrome and relationship with the use of khat and tobacco products in the Jazan region, Saudi Arabia: A prospective case-control study
Abstract
Introduction Previous studies have identified several risk factors for acute coronary syndrome (ACS). This study was intended to examine the potential risk of ACS associated with khat and tobacco use. Methods A case-control study of 344 people (172 cases and 172 controls) was conducted at Prince Mohammed Bin Nasser Hospital in Jazan, Saudi Arabia, from April to September 2019. The cases and controls were matched for age (±5 years) and gender. Data were analyzed using descriptive, inferential, and modeling analyses. We utilized the adjusted odds ratio (AOR) to express the results. Results The prevalence of ever khat chewing among all study participants was 29.1%, significantly higher for the cases with ACS than for the control group (43.6% vs 14.5%, p 0.05). In the final model, tobacco use was more likely to be reported among cases with myocardial infarction (MI) (AOR=4.58; 95% CI: 1.01–4.73, p<0.05) as was khat chewing (AOR=3.4; 95% CI: 1.55–7.46, p<0.05), after controlling for other traditional risk factors. Conclusions Khat chewing was reported more by those who reported ACS. ACS cases were more likely to be frequent khat users with chewing sessions of five or more days per week. Regular tobacco use was also reported in those who reported ACS, and this increases with the amount of tobacco used. Implementing early intervention strategies can help mitigate the impact of khat chewing and smoking on the development of ACS.
