Low Homoarginine Levels in the Prognosis of Patients With Acute Chest Pain.
2016
Background The endogenous amino acid homoarginine predicts mortality in cerebro‐ and cardiovascular disease. The objective was to explore whether homoarginine is associated with atrial fibrillation ( AF ) and outcome in patients with acute chest pain. Methods and Results One thousand six hundred forty‐nine patients with acute chest pain were consecutively enrolled in this study, of whom 589 were diagnosed acute coronary syndrome ( ACS ). On admission, plasma concentrations of homoarginine as well as brain natriuretic peptide ( BNP ), and high‐sensitivity assayed troponin I (hsTnI) were determined along with electrocardiography ( ECG ) variables. During a median follow‐up of 183 days, 60 ma…
High levels of N-terminal pro B-type natriuretic peptide are associated with ST resolution failure after reperfusion for acute myocardial infarction
2007
Background: B-type natriuretic peptide and the N-terminal fragment of its prohormone, N-terminal pro-brain natriuretic peptide (Nt-proBNP), provide valuable prognostic information on short- and long-term mortality in patients with acute coronary syndrome Aim: To investigate the association between plasma NT-proBNP levels and ST-segment resolution (STR) after reperfusion in patients with ST-segment elevation myocardial infarction (STEMI). Methods: Consecutive patients from the French regional RICO survey with STEMI who were treated by primary PCI or lysis <12 h were included. Blood sample was taken on admission to measure plasma NT-proBNP. Maximal ST segment elevation was measured on the sin…
The Usefulness of Bioelectrical Impedance Analysis in Differentiating Dyspnea Due to Decompensated Heart Failure
2007
Acute dyspnea poses a diagnostic challenge for physicians, and the current methods in differentiating cardiac from non-cardiac causes have been limited to date. Recently, the brain natriuretic peptide (BNP) rapid test has been validated in the emergency room. Nevertheless, the early accumulation of fluid in the interstitial space in the body and in the lungs, which characterizes patients with ADHF, is well estimated by BIA. We investigate whether bioelectrical impedance analysis (BIA) can serve as a noninvasive diagnostic tool in the differential diagnosis of acute decompensated heart failure (ADHF) in the emergency department (ED).A total of 292 patients presenting with acute dyspnea to th…
The glucocorticoid in acute decompensated heart failure: Dr Jekyll or Mr Hyde?
2012
Glucocorticoid administration is not recommended in patients with heart failure because of its related sodium and fluid retention. However, previous experimental and clinical studies have demonstrated that glucocorticoids can also induce a diuretic effect and improve renal function in patients with acute decompensated heart failure (ADHF) with refractory diuretic resistance. We report the case of a 65-year-old man with a known diagnosis of aortic stenosis, systolic ventricular dysfunction, and chronic obstructive pulmonary disease who was admitted for ADHF. After 3 days, during which resistance to conventional therapy was observed, intravenous methylprednisolone (60 mg/d) was added to ongoi…
Association of adiponectin with adverse outcome in coronary artery disease patients: results from the AtheroGene study
2008
In primary prevention, the adipocytokine adiponectin seems to be protective against diabetes mellitus and cardiovascular disease. Data in patients with manifest coronary artery disease (CAD) are scant stimulating the investigation of the association of adiponectin concentrations and cardiovascular outcome in a prospective CAD cohort.In 1890 consecutive patients with documented CAD [1130 with stable angina (SAP) and 760 with acute coronary syndrome (ACS)] baseline concentrations of adiponectin were measured by enzyme-linked immuno assay. During a median follow-up of 2.5 years cardiovascular events were registered (cardiovascular deaths 70; non-fatal myocardial infarction 46). Baseline adipon…
Effect of physical training on exercise capacity, gas exchange and N-terminal pro-brain natriuretic peptide levels in patients with chronic heart fai…
2006
BACKGROUND: Decreased exercise capacity is the main factor restricting the daily life of patients with chronic heart failure. N-terminal pro-brain natriuretic peptide (NT pro-BNP) is strongly related to the severity of and is an independent predictor of outcome in chronic heart failure. DESIGN: The study aimed to evaluate the effect of exercise training on functional capacity and on changes in NT pro-BNP levels and to assess the effect of exercise training on quality of life. MATERIALS AND METHODS: Sixty patients (45 men/15 women, mean age 52.7 years; +/-5.3 SD), with stable heart failure (45 ischaemic/hypertensive and 15 idiopathic patients), in New York Heart Association (NYHA) functional…
Paradoxically, iron overload does not potentiate doxorubicin-induced cardiotoxicity in vitro in cardiomyocytes and in vivo in mice
2015
Doxorubicin (DOX) is known to induce serious cardiotoxicity, which is believed to be mediated by oxidative stress and complex interactions with iron. However, the relationship between iron and DOX-induced cardiotoxicity remains controversial and the role of iron chelation therapy to prevent cardiotoxicity is called into question. Firstly, we evaluated in vitro the effects of DOX in combination with dextran-iron on cell viability in cultured H9c2 cardiomyocytes and EMT-6 cancer cells. Secondly, we used an in vivo murine model of iron overloading (IO) in which male C57BL/6 mice received a daily intra-peritoneal injection of dextran-iron (15mg/kg) for 3weeks (D0-D20) and then (D21) a single su…
Long-term serial kinetics of N-terminal pro B-type natriuretic peptide and carbohydrate antigen 125 for mortality risk prediction following acute hea…
2017
Aim: Baseline values of N-terminal pro B-type natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) predict all-cause mortality in acute heart failure (AHF). However, there is limited information about the added prognostic benefit of using longitudinal values, and how this predictive ability is modified when modelling together. The aim of this study was to determine the mutually-adjusted association between the longitudinal trajectories of NT-proBNP and CA125 with all-cause mortality after an episode of AHF. Methods and results: We included 946 consecutive patients discharged for AHF. NT-proBNP and CA125 were measured at each physician-patient encounter (median (interquartile…
Prognostic Value of Brain Natriuretic Peptide in Acute Heart Failure: Mortality and Hospital Readmission
2008
The prognostic value of brain natriuretic peptide (BNP) measurement in patients with acute heart failure is not well understood. The aim of this study was to investigate the relationship between the BNP level and mortality and readmission for acute heart failure. We studied 569 consecutive patients who were admitted with a diagnosis of acute heart failure. The BNP level was measured after the patient became clinically stable. The relationship between the BNP level and mortality was assessed by Cox regression analysis, and the relationship with readmission, by competing risks regression analysis. During a median follow-up period of 9 (range, 3-18) months, 156 deaths (27.4%) and 140 readmissi…
Troponin I release after intravenous treatment with high furosemide doses plus hypertonic saline solution in decompensated heart failure trial (Tra-H…
2012
Background High values of cardiac troponin in acute decompensated congestive heart failure (ADHF) identify patients at higher risk and worsened prognosis. A cardiac troponin increase during therapy indicates the need for more appropriate intervention, aimed at compensating cardiac disease and effectively minimizing myocardial wall stress and subsequent cytolysis. This study evaluated the effects of an intravenous high dose of furosemide with (group A) or without small volume hypertonic saline solution (HSS) (group B) on myocardial cytolysis in patients with ADHF. Methods A total of 248 consecutive patients with ADHF (148 men, mean age 74.9 ± 10.9 years) were randomly assigned to group A or …
