Prevalence of coronary artery diseases risk factors in Sari-Iran (2005-10)

Abstract

Background and Objective: Coronary artery diseases are one of the main causes of mortality and morbidity. This study was done to determine the prevalence of risk factors for coronary artery diseases in patients referred to angiography center in Sari, Northern Iran. Materials and Methods: This descriptive study was performed on 2540 patients referred to angiography center in Sari city, northern Iran, during 2005-10. Risk factors including diabetes, hypertension, hyperlipidemia, smoking, Family history, CRP and also ECG changes, type and number of involved artery and the severity of vascular involvement were recorded for each patient. Results: Hypertension, hyperlipidemia, diabetes, smoking were seen in 40.8%, 40.5%, 29.1%, 12.5% of patients, respectively. Positive family history and CRP were found in 10% and 3.4% of the patients, respectively. 23.8% of patients had abnormal ECG. One, two and three vessel diseases were observed in 26.5%, 48.3%, 48.3% of cases, respectively. Left anterior descending artery constriction was seen in 75.8% and 80.4% of males and females, respectively. A significant relationship was found between diabetes and left coronary circumflex (P<0.04) and left anterior descending artery (P<0.03) constriction. Conclusion: Diabetes, hypertension, hyperlipidemia, smoking, family history, abnormal ECG are among the risk factors of coronary artery diseases in this area
