OBJECTIVE: The midregional fragment of proadrenomedullin (MR-proADM) is a marker of endothelial dysfunction and has been associated with a variety of diseases. Our aim was to investigate whether MR-proADM is associated with new-onset albuminuria and cardiovascular (CV) and all-cause mortality in patients with type 2 diabetes treated in primary care.
RESEARCH DESIGN AND METHODS: Patients with type 2 diabetes participating in the observational Zwolle Outpatient Diabetes Project Integrating Available Care (ZODIAC) study were included. Cox regression analyses were used to assess the relation of baseline MR-proADM with new-onset albuminuria and CV and all-cause mortality. Risk prediction capabilities of MR-proADM for new-onset albuminuria and CV and all-cause mortality were assessed with Harrell's C and the integrated discrimination improvement.
RESULTS: In 1,243 patients (mean age 67 [±12] years), the median follow-up was 5.6 years (interquartile range 3.1-10.1); 388 (31%) patients died, with 168 (12%) CV deaths. Log2 MR-proADM was associated with CV (hazard ratio 1.96 [95% CI 1.27-3.01]) and all-cause mortality (1.78 [1.34-2.36]) after adjusting for age, sex, BMI, smoking, systolic blood pressure, cholesterol-to-HDL ratio, duration of diabetes, HbA1c, ACE inhibitor/angiotensin receptor blocker, history of CV diseases, log serum creatinine, and log albumin-to-creatinine ratio. MR-proADM slightly improved mortality risk prediction. The age- and sex-adjusted, but not multivariate-adjusted, MR-proADM levels were associated with new-onset albuminuria.
CONCLUSIONS: MR-proADM was associated with CV and all-cause mortality in patients with type 2 diabetes after a median follow-up of 5.6 years. There was no independent relationship with new-onset albuminuria. In the availability of an extensive set of risk factors, there was little added effect of MR-proADM in risk prediction of CV and all-cause mortality.
