The Five-Year Trend of Coronary Artery Diseases Based on Angiography Results in Central Part of IRAN

Introduction: Coronary artery disease (CASD) is the most common cause of mortality and morbidity in the world. Given the increasing prevalence of CAD in Iran, it is essential to determine its trend. Method: In this retrospective study, angiography reports of all patients admitted for coronary angiography due to stable angina or acute coronary syndromes in Noor and Sina Hospitals from 2005 to 2009 were included in this study. All of the results were evaluated by 3 expert cardiologists, and recorded in one format. Data on age, sex, angiography, and coronary artery involvement were collected and analyzed using the ANOVA model. Results: We evaluated 33388 angiography reports. The mean age of the patients was 59.48±10.49 years in 2005, 59.94±10.66 years in 2006, 60.17±10.49 years in 2007, 60.37±10.64 years in 2998, and 61.25±10.58 years in 2009, respectively. Significant involvement of coronary arteries was found in 21.7% of the males and 33.5% of the females with a mean age of 63.45 vs. ± 59.17 years, respectively (p value≤0.001). The mean age of CAD increased from 2005 to 2009 significantly (p value =0.002). Conclusion: Given the increased prevalence rate of CAD, we need broad primary and secondary CAD prevention programs. Furthermore, the early occurrence of CAD in women requires more extensive preventive plans to control their risk factors
