Title: Relationship of Cystatin-C with coronary artery disease in the elderly patients with diabetes
Abstract: Objective: To study the relationship between Cystatin C (Cys-C) level and the development of coronary heart disease in elderly patients with type 2 diabetes mellitus (T2DM). Methods: 120 cases of elderly diabetic patients were involved in this study from October 2013 to November 2015 in Department of Endocrinology and Cardiology. All patients underwent the detection of routine flash dual-source coronary computed tomography angioplasty (CCTA), Cys-C, hemoglobin A1c (HbA1c). According to the difference of CCTA results, the patients were divided into DM1 group (with normal coronary CTA), DM2 group (with a coronary artery stenosis rate < 50%), DM3 group (with a coronary artery stenosis rate of 50%-74%) and DM4 group (with a coronary artery stenosis rate of ≥ 75%). The levels of Cys-C and HbA1c were compared in the four groups. Results: The blood levels of Cys-C and HbA1c showed significant differences between DM1, DM2, DM3 and DM4 group ( p < .05). The age, heart rate, blood pressure showed no statistical differences between the groups. The level of Cys-C was positively correlated with HbA1c. Conclusions: The blood level of Cys-C in the elderly patients with T2DM increased with the increase of the degree of coronary artery stenosis. Blood Cys-C may be used as an early predictor of coronary artery lesions in elderly patients with T2DM.
