Abstract:

Objective To explore the correlation between urinary transferrin to urinary creatinine ratio (uTRF/Cr) and new onset cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM). Methods A total of 8 163 T2DM patients who participated in the 6th health examination in Kailuan and underwent urinary transferrin and urinary creatinine detection were recruited. Subjects were divided into the first group (n=2 721), the second group (n=2 721), and the third group (n=2 721) based on baseline uTRF/Cr. The effects of uTRF/Cr on the risk of CVD were analyzed by multivariate Cox regression model. Results The baseline age of the study population was (60.46±9.96) years, with 78.30% of males, and 0.24(0.16-0.47) mg/mmol of baseline uTRF/Cr. The median follow-up time was 3.85(3.43-4.22) years, with 411(6.79%) of CVD events occurred. The cumulative incidence of total CVD events in the first, second and third groups was 3.81%, 4.65%, and 7.29%, respectively. After adjusting for relevant influencing factors, the risk of total CVD events in the second and third groups of uTRF/Cr was 1.12(95%CI 0.86-1.46) times and 1.52(95%CI 1.18-1.97) times that in the first group, respectively. Conclusion Increased uTRF/Cr is an independent risk factor for CVD in T2DM populations, and the risk of CVD increases with increased uTRF/Cr, even before the onset of macroalbuminuria.
