Prevalence of Coronary Artery Disease and the Associated Risk Factors in the Adult Population of Borujerd City, Iran
Background: Cardiovascular events are the leading cause of mortality and are highly associated with lifestyle. We aimed to evaluate the prevalence of coronary artery disease (CAD) and its major risk factors in the western Iranian city of Borujerd.
Methods: This cross-sectional study was conducted on 801 subjects older than 35 years of age, recruited via cluster sampling in Borujerd. The diagnosis of CAD was based on the positive results of Rose Angina Questionnaire, Minnesota coding, or prior history of CAD. Then, the risk factors were measured by biochemistry and relevant laboratory examinations, or data extraction from the subjects’ history.
Results: The study sample consisted of 412 men and 389 women at a mean age of 54.82±12.11 years. The prevalence of risk factors including hypertension, diabetes mellitus, dyslipidemia, smoking, and obesity was 38.2%, 17.4%, 64%, 23.2%, and 22.8%, respectively. Based on the criteria, 19.1% and 31.7% of the CAD cases were definite and probable, respectively. Furthermore, 12.5% had definite signs and symptoms of CAD, and 5.4% had positive Rose Angina Questionnaire outcomes.
Conclusion: The current study demonstrated the distribution of CAD in the Iranian city of Borujerd and it was demonstrated that obesity and smoking are the most common risk factors, respectively.
