title: Elevated risk of an intermediate or high SYNTAX score in subjects with impaired fasting glucose.
abstract: OBJECTIVE
  This study was designed to determine the SYNTAX score under different fasting plasma glucose (FPG) states in Chinese patients undergoing coronary angiography, particularly subjects with impaired FPG.
  
  
  METHODS
  Four hundred and forty-six subjects undergoing coronary angiography were enrolled in this study and divided into four groups based on the FPG level or a history of type 2 diabetes mellitus (T2DM): normal FPG, impaired FPG, known and previously unknown T2DM.
  
  
  RESULTS
  The angiographic SYNTAX scores were higher in the subjects with known (p<0.001) or previously unknown (p<0.001) T2DM than in those with normal FPG. There were significant differences in the number of diseased coronary artery vessels between the subjects with known (p<0.01) or unknown T2DM (p<0.05) and the subjects with normal FPG. However, there were no significant differences in the SYNTAX score or the number of diseased coronary artery vessels between the subjects with impaired FPG and those with normal FPG. The subjects with impaired FPG (2.917-fold, p=0.004) and known (3.064-fold, p=0.000) or previously unknown (3.301-fold, p=0.000) T2DM exhibited a significantly elevated risk of having an intermediate or high SYNTAX score compared with the subjects with normal FPG.
  
  
  CONCLUSIONS
  Chinese subjects with impaired FPG have a significantly elevated risk of having an intermediate or high SYNTAX score, indicating a risk of severe coronary artery lesions. Subjects with known or previously unknown T2DM may have severe coronary artery lesions. These findings suggest the importance of achieving better glycemic control in order to prevent coronary atherosclerosis and improve the cardiovascular prognosis.
