Abstract

BACKGROUND: Diabetes mellitus (DM) is associated with an adverse outcome in heart failure (HF). Increased concentrations of midregional proadrenomedullin (MR-proADM) have been associated with DM and are predictors of mortality in HF patients. The aim of this study was to elucidate the impact of DM on MR-proADM concentrations and the prognostic value regarding all-cause mortality and hospitalization among HF patients.

METHODS AND RESULTS: We included 366 patients from an HF clinic; 69 (19%) had a history of DM and 40 (11%) had newly diagnosed DM (HbA1c ≥48 mmol/mol). The median MR-proADM concentration was unaffected by DM status (P = .20) but increased in HF patients with impaired renal function (P < .001). During a median follow-up of 55 months, 189 died, and 292 either died or were hospitalized. After adjustment for clinically relevant parameters, MR-proADM was associated with all-cause mortality (hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.1-1.4; P = .01) and the combined end point of death and hospitalization (HR 1.2, 95% CI 1.1-1.4; P = .02) per 1 SD increment of ln-transformed variable. No interaction between DM and MR-proADM was found regarding mortality or hospitalization.

CONCLUSIONS: Diabetes status had no impact on MR-proADM concentrations or in the predictive ability of MR-proADM in HF patients.
