BACKGROUND: @entity27 ( @entity27 ) is a highly prevalent @entity25 that is associated with increased risk of @entity101 ( @entity101 ) and @entity301 . This study aimed to evaluate the correlation between the @entity27 and @entity453 ( @entity453 ) severity. METHODS: The cross-sectional study was conducted from September 2012 to December 2013. We enrolled 127 @entity1 with @entity5749 who were referred for coronary angiographic studies in Shahid Chamran and Nour Hospitals in Isfahan, Iran. The Berlin questionnaire (BQ) was used for estimate the probability of @entity27 in @entity1 as a low or high probability. Demographic characteristics and metabolic risk factors including @entity6 , @entity101 , @entity28 , and smoking also were recorded. The severity of @entity453 was assessed and compared based on the Gensini score with Mann-Whitney U statistical test. Independent t-test for continuous variables and chi-square test for categorical variables were used. RESULTS: Totally, 65.4% of subjects were considered as high and 34.6% as low probability for @entity27 , which 81.1% of them had @entity453 . There was a significant difference between body mass index, systolic blood pressure, diastolic blood pressure, and @entity63 heart disease drug consumption with @entity27 probability (P < 0.0500). @entity453 was accompanied by @entity27 significantly (P = 0.0260). The Gensini score was significantly higher in @entity1 with high @entity27 probability (100.4    69.1 vs. 65.3    68.9; P = 0.0030). @entity27 also increase odds of @entity453 based on regression analysis (odds ratio, 95% confidence interval = 2.7). CONCLUSION: This study indicates that more severe @entity453 is associated with high @entity27 probability identified by BQ.
