Prognostic value of human mature adrenomedullin in patients with acute myocardial infarction.

Adrenomedullin (ADM) correlates with adverse cardiovascular outcomes in patients with acute myocardial infarction (AMI) and in patients with heart failure. Measurement of human mature ADM (mADM) has been difficult, and recent studies have used its surrogate - the mid-regional pro-ADM (MRproADM). Our objective was to determine whether mADM measured by a novel sandwich immunoassay, using the anti-C-terminal and an anti-mid-regional monoclonal antibody, was prognostic of 30-day, 90-day, 1-year, and 2-year major adverse cardiovascular events (MACEs) in 1111 consecutive patients who have suffered an AMI.

Prognostic significance of adrenomedullin in patients with heart failure and with myocardial infarction.

We undertook this systematic review to determine the prognostic significance of adrenomedullin (ADM) in patients with heart failure and acute myocardial infarction (AMI). Given the difficulty in measuring mature ADM, its surrogate, midregional proadrenomedullin (MRproADM) has been used in most studies. Systematic search of original published studies through MEDLINE and the Cochrane Collaboration databases restricted to reports in English from January 1, 1993, to June 30, 2014, in humans was undertaken.

Pre-discharge risk stratification in unselected STEMI: is there a role for ST2 or its natural ligand IL-33 when compared with contemporary risk markers?

Background: Soluble ST2 is a marker of cellular stress and injury whose natural ligand is interleukin-33. We investigate, for the first time, the relationship of IL-33 and ST2 with death at 30-days, 1-year and beyond in unselected STEMI patients. We assess the incremental value they offer over GRACE score and NT-proBNP.

Interleukin 33 and ST2 in non-ST-elevation myocardial infarction: comparison with Global Registry of Acute Coronary Events Risk Scoring and NT-proBNP.

Background: Soluble ST2 is a marker of biomechanical strain for which the natural ligand is interleukin 33 (IL-33). They have not been studied together in non-ST-elevation myocardial infarction (NSTEMI). We investigated their relationship with death, heart failure (HF) readmission, and reinfarction combined (termed major adverse cardiac events [MACE]) and, separately, in unselected patients using Global Registry of Acute Coronary Events Risk Scoring (GRACE-RS) and n terminal pro B type natriuretic peptide (NT-proBNP) as benchmark comparators.

Prognostic value of mid-regional pro-adrenomedullin levels taken on admission and discharge in non-ST-elevation myocardial infarction: the LAMP (Leicester Acute Myocardial Infarction Peptide) II study.

Objectives: The purpose of this study was to assess the prognostic value of admission and discharge mid-regional pro-adrenomedullin (sAM) levels in non-ST-elevation myocardial infarction (MI) and identify values to aid clinical decision making. N-terminal pro-B-type natriuretic peptide and GRACE (Global Registry of Acute Coronary Events) score were used as comparators.

Background: sAM is a stable precursor of adrenomedullin.

Matrix metalloproteinase-2 predicts mortality in patients with acute coronary syndrome.

The aim of the present study was to investigate the predictive value of MMP (matrix metalloproteinase)-2, MMP-3 and MMP-9 levels in patients with acute coronary syndrome for death, readmission with HF (heart failure) or recurrent MI (myocardial infarction) and to compare them with established markers, NT-proBNP (N-terminal pro-B-type natriuretic peptide) and the GRACE (Global Registry of Acute Coronary Events) score. A single blood test was taken 4 days after admission in 1024 consecutive patients with acute MI with end points observed over 519 (134-1059) days [value is median (range)]. MMP-2 and MMP-3 were increased in patients who died (n=111) compared with survivors (P<0.
