[Associations of glycated albumin level with coronary artery disease].

OBJECTIVE

To explore the associations of the level of glycated albumin (GA) with coronary artery disease (CAD).

METHODS

A total of 306 patients undergoing coronary angiography (CA) were collected. There were 201 males and 105 females with an age range of 38-86 years. CA was the major diagnostic criteria of CAD. Metabolic syndrome was diagnosed according to the Guideline on Prevention & Treatment of Blood Lipid Abnormality in Chinese Adults.

RESULTS

(1) CAD was found in 227 patients (74.2%). The levels of 2 h postprandial glucose, GA and hemoglobin A1c in the CAD patients were higher than those in the non-CAD counterparts (all P < 0.05). (2) In the subgroup of normal glucose tolerance (NGR), the CAD patients had a higher level of GA than the non-CAD patients ((15.0 ± 2.1)% vs (13.3 ± 1.7)%, P < 0.01). And the level of GA was higher in the patients with 1-vessel ((14.8 ± 2.1)% vs (13.3 ± 1.7)%, P < 0.05) and multi-vessel lesions ((15.1 ± 2.1)% vs (13.3 ± 1.7)%, P < 0.05) than that in the non-CAD counterparts (all P < 0.05). Similar results were obtained in the hyperglycemia subgroup. (3) Logistic regression demonstrated that the level of GA was independently correlated with CAD after adjusting other traditional factors among all subjects, NGR and hyperglycemia subgroup.

CONCLUSIONS

The serum level of GA becomes significantly elevated the CAD patients. And it is an independent risk factor of CAD in both hyperglycemic and NGR patients.
