Abstract 11949: Glycated Hemoglobin Correlates with the SYNTAX Score of Candidate for First Coronary Angiography
Background Glycated hemoglobin is associated with risks of cardiovascular disease and death from any cause. However there is no previous study to evaluate the predictive value of glycated hemoglobin for the complexity of coronary artery disease.
Methods Subjects were 494 consecutive patients who underwent first coronary angiography and were measured glycated hemoglobin from December 2008 to May 2011. Study patients were divided into 5 groups according to the glycated hemoglobin value. The complexity of the coronary artery lesions were evaluated by using the SYNTAX score. The SYNTAX score was calculated using the SYNTAX score algorithm on the SYNTAX website.
Results The glycated hemoglobin value was significantly associated with the SYNTAX score. Glycated hemoglobin values of less than 5.0%, 5.0 to less than 5.5%, 5.5 to less than 6.0%, 6.0 to less than 6.5%, and 6.5% or greater, the SYNTAX score were 6.1±13.2, 8.2±15.6, 7.8±13.0, 10.6±13.6, and 12.8±14.8, respectively (p=0.038). In contrast, fasting glucose level did not have correlation with the severity of the SYNTAX score.
Conclusions Glycated hemoglobin significantly associates with the complexity of coronary artery disease, but fasting glucose does not, in the candidates for elective coronary angiography.
