Coronary artery lesions and some of its related factors in more than 5000 patients in kosar Angiography Center (Golestan Province) from 2007 to 2009

Coronary heart disease is the most common cause of death in Iran and most parts of the world. Major factors are involved in severity and extension of arterial obstruction. There have been different reports about location and severity of coronary artery lesions. This study determines factors related to the severity of coronary artery obstruction in the patients in kosar Angiography Center. This was a descriptive analytical study and included 5444 patients. The characteristics of every patient were recorded in a check list. After measurement of blood pressure of the patients and recording history of hypertension, diabetes and drug consumption, data were introduced into a special software and then SPSS (16.00) software. Data analysis was performed by ANOVA, Kruskal-Wallis and Chi-square tests. p≤0.05 was considered significant. 52% of the patients were male and 48% were female. 6.7%, 6.47%, 30.32% and18.7% of the lesions was located in LAD, RCA, CX and OMSN respectively. RCA, OMSN, CX and LAD branches had obstructions of less than 50% (28.1%, 16%, 25.8% and 39% respectively). 38.2% of the patients had history of hypertension and 24.6% had history of diabetes. Location and severity of the lesions in some branches showed significant relationships with hypertension, diabetes and gender (p<0.001). But location and severity of the lesions had no relationship with residence and education level. The results of this study showed the location and severity of the lesions in the patients with coronary artery disorders were associated with certain risk factors which were compatible with the results of other studies. Considering the results of this study, it is necessary to take measures for diagnosis and prevention of this disease.
