    Abstract:
    AIMS: The aim of this study was to evaluate the long-term prognostic utility of mid-region prohormone adrenomedullin (MR-proADM) in stable outpatients with heart failure (HF). METHODS AND RESULTS: Echocardiogram and serum for MR-proADM and BNP levels were obtained in 724 stable outpatients. These patients were followed for up to 6 years for the primary endpoint of all-cause mortality. There were 198 stage A patients, 328 stage B patients, and 200 stage C/D patients, with an average age of 68 ± 12 years. There were 195 deaths during the 6-year follow-up period. MR-proADM was predictive of mortality in the overall patient population. The predictive value of MR-proADM for long-term mortality was independent of BNP, echocardiographic indices of structural heart disease, clinical predictors of mortality, and the Framingham risk score. Patients with elevated MR-proADM had significantly increased risk for mortality in stage A and stage C/D HF, with hazard ratio (HR) 3.780, P < 0.001 and HR 2.744, P < 0.001, respectively. There was a trend toward increased mortality in patients with elevated MR-proADM and stage B HF (HR 1.579, P = 0.05005). MR-proADM added incremental predictive value to clinical predictors and the Framingham risk score. CONCLUSIONS: MR-proADM was a potent independent predictor of long-term all-cause mortality in stable outpatients with stage A-D HF, especially in patients in stage A and stage C/D HF. MR-proADM added incremental predictive value to clinical predictors and the Framingham risk score.
