Differential Prognostic Value of Galectin-3 According to Carbohydrate Antigen 125 Levels in Transcatheter Aortic Valve Implantation

2019

Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have been associated with adverse outcomes after transcatheter aortic valve implantation (TAVI). Experimental data have suggested a potential molecular interaction. Therefore, we assessed the association of Gal-3 and CA125 with prognosis after TAVI.A total of 439 patients were enrolled. The primary endpoint was a composite of all-cause mortality or readmission for worsening heart failure after TAVI.The primary endpoint occurred in 16.4%. Gal-3 was dichotomized at ≥ 8.71 ng/mL into elevated and not elevated. Gal-3 was elevated in 31.9% and was associated with a higher risk of the primary endpoint (25% vs 12.4%, HR, 2.26; P.001). After m…

Plasma neutrophil gelatinase-associated lipocalin and long-term mortality in patients with acute heart failure and normal renal function

2015

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a renal tubular marker for early renal dysfunction [1]. Recent studies highlighted its role in predicting acute kidney injury (AKI) and clinical outcomes in a wide range of cardiovascular diseases [2], [3], [4] and [5]. However, in heart failure (HF), conflicting results have been reported [4], [5], [6] and [7] and some ambiguities still prevail about the prognostic utility of NGAL beyond standard prognosticators and traditional renal biomarkers. We aimed to evaluate the independent ability of serum NGAL for predicting long-term mortality in patients admitted for acute HF (AHF). We prospectively enrolled 206 patients consecuti…

Prognostic value of the interaction between galectin-3 and antigen carbohydrate 125 in acute heart failure

2015

AIM:Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have emerged as robust prognostic biomarkers in heart failure. Experimental data have also suggested a potential molecular interaction between CA125 and Gal-3; however, the biological and clinical relevance of this interaction is still uncertain. We sought to evaluate, in patients admitted for acute heart failure, the association between plasma Gal-3 with all-cause mortality and the risk for rehospitalizations among high and low levels of CA125. METHODS AND RESULTS: We included 264 consecutive patients admitted for acute heart failure to the Cardiology Department in a third-level center. Both biomarkers were measured on admission. …

2019

Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the st…

Usefulness of the neutrophil to lymphocyte ratio in predicting long-term mortality in ST segment elevation myocardial infarction.

2007

Neutrophil to lymphocyte ratio (N/L) has been associated with poor outcomes in patients who underwent cardiac angiography. Nevertheless, its role for risk stratification in acute coronary syndromes, specifically in patients with ST-segment elevation myocardial infarction (STEMI), has not been elucidated. We sought to determine the association of N/L maximum value (N/L max) with mortality in the setting of STEMI and to compare its predictive ability with total white blood cell maximum count (WBC max). We analyzed 515 consecutive patients admitted with STEMI to a single university center. White blood cells (WBC) and differential count were measured at admission and daily for the first 96 hour…

Relationship between low lymphocyte count and major cardiac events in patients with acute chest pain, a non-diagnostic electrocardiogram and normal t…

2008

Risk stratification of patients with acute chest pain, non-diagnostic electrocardiogram and normal troponin (ACPneg) remains a challenge, partly because no standardized set of biomarkers with prognostic ability has been identified in this population. Lymphopenia has been associated with atherosclerosis progression and adverse outcomes in cardiovascular diseases; although its prognostic value in ACPneg is unknown. We sought to determine the relationship between the lymphocyte count obtained in the Emergency Department (ED) and the risk of the long-term all-cause mortality or myocardial infarction (MI) in patients with ACPneg.We analyzed 1030 consecutive patients admitted with ACPneg in our i…

Prognostic usefulness of white blood cell count on admission and one-year outcome in patients with non-ST-segment elevation acute chest pain.

2006

Little is known about the prognostic value of leukocyte count on admission for patients with chest pain. In total, 1,461 patients who presented to the emergency department with non–ST-segment elevation chest pain were studied by clinical history, electrocardiography, serial troponin I determination, and leukocyte count on admission. End points were 1-year mortality and major events (mortality or infarction). Overall patient distribution by quartiles of leukocyte count showed increased mortality (6%, 7%, 6%, and 17%, p = 0.0001) and major events (13%, 13%, 15%, and 24%, p = 0.0001) in the fourth quartile. After adjustment for other risk factors, the fourth quartile cut-off value (>10,000 cel…

Overexpression of genes involved in lymphocyte activation and regulation are associated with reduced CRM-derived cardiac remodelling after STEMI

2021

Abstract Aims Lymphopenia after ST-segment elevation myocardial infarction (STEMI) correlates with deleterious cardiac consequences and worse prognosis. An in-depth examination of genes implicated in lymphocyte proliferation, activation and regulation and their association with short- and long-term cardiac structure and function is therefore of great interest. Methods Peripheral blood mononuclear cells were isolated from 10 control subjects and 64 patients with a first STEMI treated with primary percutaneous coronary intervention and submitted to cardiac magnetic resonance after 1 week and 6 months. mRNA expression of genes implicated in lymphocyte activation (CD25 and CD69) and regulation …

International Normalized Ratio and Mortality Risk in Acute Heart Failure and Nonvalvular Atrial Fibrillation Patients Receiving Vitamin K Antagonists

2019

Introduction and objectives: Heart failure patients with nonvalvular atrial fibrillation (NVAF) on treatment with vitamin K antagonists (VKA) often have suboptimal international normalized ratio (INR) values. Our aim was to evaluate the association between INR values at admission due to acute heart failure and mortality risk during follow-up. Methods: In this observational study, we retrospectively assessed INR on admission in 1137 consecutive patients with acute heart failure and NVAF who were receiving VKA treatment. INR was categorized into optimal values (INR = 2-3, n = 210), subtherapeutic (INR 3, n = 267). Because INR did not meet the proportional hazards assumption for mortality, res…

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…

2022

Introduction and objectives: Carbohydrate antigen 125 (CA125) has been shown to be useful for risk stratification in patients admitted with acute heart failure (AHF). We sought to determine a CA125 cutpoint for identifying patients at low risk of 1-month death or the composite of death/HF readmission following admission for AHF.Methods: The derivation cohort included 3231 consecutive patients with AHF. CA125 cutoff values with 90% negative predictive value (NPV) and sensitivity up to 85% were identified. The adequacy of these cutpoints and the risk of 1-month death/HF readmission was then tested using the Royston-Parmar method. The best cutpoint was selected and externally validated in a co…

Prevalence and prognostic implications of active cytomegalovirus infection in patients with acute heart failure

2010

AHF (acute heart failure) causes significant morbidity and mortality. Recent studies have postulated that the expression of inflammatory mediators, such as cytokines and chemokines, plays an important role in the development and progression of heart failure. A pro-inflammatory state has been postulated as a key factor in triggering CMV (cytomegalovirus) reactivation. Therefore we sought to determine the prevalence of active CMV infection in immunocompetent patients admitted for AHF and to quantify the association with the risk of the combined end point of death or AHF readmission. A total of 132 consecutive patients admitted for AHF were enrolled in the present study. Plasma CMV DNAaemia wa…

Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality

2005

Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…

Utilidad de la troponina I para predecir la disfunción sistólica en los síndromes coronarios agudos. Resultados de un estudio prospectivo y cuantitat…

2003

The relationship between troponin I and systolic function (quantitative contrast ventriculography) was evaluated in 137 consecutive patients with a first acute coronary syndrome (60 with and 77 without ST elevation). In general, a larger troponin I peak value was related with a more depressed ejection fraction and poorer regional systolic function (p < 0.0001). Nevertheless, this correlation was weaker than expected, especially in those cases without ST-segment elevation, suggesting that other factors apart from systolic dysfunction must be taken into account in order to explain the worse prognosis of those patients with increased serum levels of this marker of myocardial damage.

[Relationship of C-reactive protein levels with angiographic findings and markers of necrosis in non-ST-segment elevation acute coronary syndrome].

2004

The mechanism responsible for elevated C-reactive protein levels (inflammation of the ruptured atherosclerotic plaque or myocardial necrosis) in acute coronary syndromes is controversial. The aim of this study was to investigate the relationship between C-reactive protein levels and angiographic complexity of the culprit lesion and troponin elevation in patients with non-ST elevation acute coronary syndromes.The study group consisted of 125 patients with single-vessel disease. Troponin-I and C-reactive protein were measured, and the complexity of the culprit lesion was analyzed (TIMI flow and thrombus).

Hyperuricemia in acute heart failure. More than a simple spectator?

2007

Hyperuricemia is a prevalent condition in chronic heart failure (CHF), describing increased oxidative stress and inflammation. Although there is evidence that serum uric acid (UA) predicts mortality in CHF, its role as a prognostic biomarker in acute heart failure (AHF) has not yet been well assessed. The aim of this study was to determine if UA levels predict all-cause mortality. Additionally, as a secondary endpoint we sought the clinical predictors of UA serum level in this population.We analyzed 560 consecutive patients with AHF admitted in a single university center. UA (mg/dl) was measured during early hospitalization. Patient survival status was followed up after discharge (median fo…

Clinical utility of antigen carbohydrate 125 for planning the optimal length of stay in acute heart failure.

2021

BACKGROUND: The optimal length of stay (LOS) in patients hospitalized for acute heart failure (AHF) remains controversial. Plasma antigen carbohydrate 125 (CA125) has emerged as a reliable proxy of congestion. We aimed to evaluate whether there is a differential impact of LOS on the risk of 6-month AHF readmission across CA125 levels. METHODS: This is a retrospective study that included 1,387 patients discharged for AHF in two third-level centers. CA125 was measured 48±24h after admission. The association between CA125 and LOS with the risk of subsequent AHF readmission at 6 months was analyzed by Cox regression analysis accounting for death as a competing event. RESULTS: The median (IQR) a…

The primary endpoint was the composite of death, spontaneous myocardial infarction, heart failure (HF), or stroke. The association between symptoms-guided revascularization after a negative stress-CMR and the endpoint was assessed using the multivariable Cox proportional hazar…

Diuretic Strategies in Acute Heart Failure and Renal Dysfunction: Conventional vs Carbohydrate Antigen 125-guided Strategy. Clinical Trial Design

2017

Abstract Introduction and objectives The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic str…

Differential prognostic effect of systolic blood pressure on mortality according to left-ventricular function in patients with acute heart failure.

2009

Aims To evaluate the relationship between systolic blood pressure (SBP) and long-term mortality in patients with acute heart failure (AHF) stratified by ejection fraction (LVEF): reduced (≤40%) vs. preserved (≥50%). Methods and results We studied 1049 consecutive patients admitted with AHF. Systolic blood pressure was determined in the emergency department. Left-ventricular ejection fraction was categorized as ≤40% (n = 288), 41–49% (n = 174), or ≥50% (n = 587). Cox regression analysis was used for multivariable analysis. Mean age and SBP were 73 ± 11 years and 150 ± 36 mmHg, respectively. During a median follow-up of 18 months, 290 deaths (33.1%) were identified. Higher SBP was associated …

Early serum creatinine changes and outcomes in patients admitted for acute heart failure: the cardio-renal syndrome revisited.

2017

Background: The changes in renal function that occurred in patients with acute decompensated heart failure (ADHF) are prevalent, and have multifactorial etiology and dissimilar prognosis. To what extent the prognostic role of such changes may vary according to the presence of renal insufficiency at admission is not clear. Accordingly, we sought to determine whether early creatinine changes (Cr) (admission to 48-72 hours) had an effect on 1-year mortality relative to the presence of renal insufficiency at admission. Methods: We included 705 consecutive patients admitted with the diagnosis of ADHF. Admission renal insufficiency was defined as serum creatinine 1.4mg/dl (A-RIcr) or estimated gl…

CA125 but not NT-proBNP predicts the presence of a congestive intrarenal venous flow in patients with acute heart failure

2021

Abstract Background Intrarenal venous flow (IRVF) measured by Doppler ultrasound has gained interest as a potential surrogate marker of renal congestion and adverse outcomes in heart failure. In this work, we aimed to determine if antigen carbohydrate 125 (CA125) and plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with congestive IRVF patterns (i.e., biphasic and monophasic) in acute heart failure (AHF). Methods and results We prospectively enrolled a consecutive cohort of 70 patients hospitalized for AHF. Renal Doppler ultrasound was assessed within the first 24-h of hospital admission. The mean age of the sample was 73.5 ± 12.3 years; 47.1% were female, and…

Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.

2015

BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4).

Comparison of Carbohydrate Antigen 125 and N-Terminal Pro-Brain Natriuretic Peptide for Risk Prediction After Transcatheter Aortic Valve Implantation

2017

Elevated carbohydrate antigen 125 (CA125) and N-terminal pro-brain natriuretic peptide (NTproBNP) have been associated with adverse outcome after transcatheter aortic valve implantation (TAVI). This study performs a comparison of both biomarkers for prognosis after TAVI. The study includes 363 patients. The primary end point was all-cause death or readmission for worsening congestive heart failure within 1 year after TAVI, and this end point occurred in 16% of the population. The optimal cutoff to predict the primary end point was 18.4 U/ml for CA125 and 2,570 ng/L for NTproBNP. Elevated CA125 levels were present in 52% and were associated with a higher rate of the primary end point (27% vs…

Differential mortality association of loop diuretic dosage according to blood urea nitrogen and carbohydrate antigen 125 following a hospitalization …

2012

Recent observations in chronic stable heart failure suggest that high-dose loop diuretics (HDLDs) have detrimental prognostic effects in patients with high blood urea nitrogen (BUN), but recent findings have also indicated that diure- tics may improve renal function. Carbohydrate antigen 125 (CA125) has been shown to be a surrogate of systemic congestion. We sought to explore whether BUN and CA125 modulate the mortality risk associated with HDLDs following a hospitalization for acute heart failure (AHF). Methods and results We analysed 1389 consecutive patients discharged for AHF. CA125 and BUN were measured at a mean of 72+12 h after admission. HDLDs (≥120 mg/day in furosemide equivalent d…

Estrategia de revascularización invasiva en el síndrome coronario sin elevación del segmento ST. El debate continúa

2009

Revascularization strategy in the setting of non-ST-segment acute coronary syndromes remains a controversy. Evidence obtained from clinical trials, generally performed in selected patients, reveals heterogeneous and insufficient results when a routine invasive revascularization strategy and a conservative one are compared. The conflicting results among trials are due to differences in: a) baseline characteristics; b) methodology and protocols applied and; c) objectives and outcomes definitions. Although present guidelines recommend that a routine invasive strategy should be used in high risk non-ST-segment elevation acute coronary syndromes, there is no consistent evidence that supports thi…

Low Lymphocyte Count and Cardiovascular Diseases

2011

Inflammation plays a crucial pathophysiological role in the entire continuum of the atherosclerotic process, from its initiation, progression, and plaque destabilization leading ultimately to an acute coronary event. Furthermore, once the clinical event has occurred, inflammation also influences the left ventricular remodelling process. Under the same paradigm, there is evidence that lymphocytes play an important role in the modulation of the inflammatory response at every level of the atherosclerotic process. Low lymphocyte count (LLC) is a common finding during the systemic inflammatory response, and clinical and animal studies suggest that LCC plays a putative role in accelerated atheros…

Right ventricular function and iron deficiency in acute heart failure

2021

Abstract Aims Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. Methods and results We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was de…

Usefulness of C-reactive protein and left ventricular function for risk assessment in survivors of acute myocardial infarction.

2004

The additional prognostic information provided by C-reactive protein (CRP) to parameters of left ventricular function in survivors of acute myocardial infarction (AMI) was investigated in 665 patients (326 with ST elevation and 339 with non-ST elevation). Cox multivariable analysis identified the following predictors of 6-month cardiac death: age (per 5 years hazard ratio [HR] 1.2, 95% confidence interval [CI] 1.1 to 1.4, p = 0.004), Killip class >I at presentation (HR 2.4, 95% CI 1.3 to 4.5, p = 0.0001), a reduced ejection fraction (per 5% HR 1.3, 95% CI 1.2 to 1.4, p = 0.0001), and greater CRP (per 5 mg/L HR 1.02, 95% CI 1.01 to 1.04, p = 0.02); the C-index of the model was 0.77 without a…

P864Histopathological damages in the epicardial coronary artery after ischemia and reperfusion injury in swine

2019

Abstract Background The microscopic consequences in the myocardial capillaries after myocardial infarction (MI) have been widely addressed, but little attention has been paid to epicardial coronary arteries. Since epicardial circulation is responsible for providing blood flow to the heart, understanding the microscopical changes on the epicardial artery after MI becomes also crucial. Purpose To evaluate the dynamics of the microscopic damages in the coronary arteries post-MI in swine model of reperfused MI. Methods MI was induced in swine by transient 90-min coronary occlusion of the left anterior descending (LAD) coronary artery using angioplasty balloons. One control group and four MI gro…

Antigen carbohydrate 125 and creatinine on admission for prediction of renal function response following loop diuretic administration in acute heart …

2014

The use of loop diuretics in acute heart failure (AHF) is largely empirical and has been associated with renal function impairment by reducing renal perfusion but also renal improvement by decreasing renal venous congestion. Antigen carbohydrate 125 (CA125) has emerged as a proxy for fluid overload. We sought to evaluate whether the early changes in creatinine (ΔCr) induced by intravenous furosemide doses (ivFD) differ among clinical groups defined by overload status (CA125) and creatinine on admission (Cr).We included 526 consecutive patients admitted for AHF. All patients received intravenous furosemide for the first 48 hours. CA125 and Cr were dichotomized at 35 U/ml and 1.4 mg/dl, respe…

Left ventricular ejection fraction recovery in patients with heart failure treated with intravenous iron: a pilot study

2016

Aims In patients with heart failure with reduced ejection fraction (HFrEF) and iron deficiency, treatment with intravenous iron has shown a clinical improvement regardless of anaemic status. Cardiac magnetic resonance (CMR) T2* sequence has shown a potential utility for evaluating myocardial iron deficiency. We aimed to evaluate whether T2* sequence significantly changes after ferric carboximaltose (FCM) administration, and if such changes correlate with changes in left ventricle ejection fraction (LVEF). Methods and results In this pilot study, we included eight patients with chronic symptomatic (New York Heart Association II–III) HFrEF and iron deficiency. A CMR, including T2* analysis, w…

Benefits of Statin Therapy Based on Plasma Carbohydrate Antigen 125 Values Following an Admission for Acute Heart Failure

2011

The prognostic benefit of statins in patients with heart failure is a topic of controversy. Under the hypothesis that statins may provide greater benefit in a subgroup of patients with heightened inflammatory activity, we sought to explore whether statins are associated with a decreased risk of long-term mortality in patients with acute heart failure based on elevated levels of carbohydrate antigen 125, a biomarker related to systemic congestion and proinflammatory status.We analysed 1222 consecutive patients admitted with acute heart failure in a single teaching center during a median follow-up of 20 months. carbohydrate antigen 125 was measured during index hospitalization and dichotomize…

P674Metabolic deregulation in myocardial infarction is mediated by PGC-1 alpha pathway

2014

Purpose: In the context of myocardial infarction (MI) the availability of metabolites is clearly restricted, therefore a fuel metabolic shifts takes place. Previous studies have indicated that peroxisome proliferator activated receptor co-activator alpha (PGC-1α) pathway is a crucial regulator of cardiac metabolism in response to cardiac stress. Here we address the role of PGC-1α in regulating metabolic changes of MI. Methods: We studied a group of 12 common swine in which anterior MI was induced by means of angioplasty balloon inflation. A series of 6 swine were sacrificed at 48h post-infarction (acute infarction group) and another series of 6 swine were sacrificed at 3 weeks (chronic infa…

Early urinary sodium trajectory and risk of adverse outcomes in acute heart failure and renal dysfunction.

2021

Introduction and objectives: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24 hours (Delta UNa24 h) adds any additional prognostic information over baseline values. Methods: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydra…

2006

Introduction and objectives Advanced diabetes can be associated with diffuse coronary artery disease that is difficult to treat by revascularization. We studied angiographic findings and disease progression in patients with advanced diabetes (either insulin-dependent or taking antidiabetic drugs for >5 years) and non-ST-elevation acute coronary syndrome who were being treated using an invasive strategy. Methods The study included 141 patients. The extent of the coronary artery disease was quantified using a score derived from a 29-segment coronary angiogram. The composite endpoint was death, myocardial infarction, or readmission for unstable angina within one year of follow-up. Results The …

Prognostic Implications of Tissue Doppler Imaging-Derived E/Ea Ratio in Acute Heart Failure Patients

2014

Background Tissue Doppler–derived transmitral to mitral annular early diastolic velocity ratio (E/Ea), as a noninvasive estimation of left ventricular (LV) filling pressures, is a strong prognosticator in various cardiac scenarios including chronic heart failure; nevertheless, its utility for risk stratification in the whole spectrum of acute heart failure (AHF) patients remains elusive. Thus, the aim of this study was to determine the association between E/Ea ratio and 1-year mortality in nonselected patients with AHF. Methods The study included 417 consecutive patients admitted for AHF. Twenty-two patients were excluded due to nonaccurate Ea measurements, leaving the final sample to be 39…

CA125-Guided Diuretic Treatment Versus Usual Care in Patients With Acute Heart Failure and Renal Dysfunction

2020

BACKGROUND: The optimal diuretic treatment strategy for patients with acute heart failure and renal dysfunction remains unclear. Plasma carbohydrate antigen 125 (CA125) is a surrogate of fluid overload and a potentially valuable tool for guiding decongestion therapy. The aim of this study was to determine if a CA125-guided diuretic strategy is superior to usual care in terms of short-term renal function in patients with acute heart failure and renal dysfunction at presentation. METHODS: This multicenter, open-label study randomized 160 patients with acute heart failure and renal dysfunction into 2 groups (1:1). Loop diuretics doses were established according to CA125 levels in the CA125-gui…

Procalcitonin and long-term prognosis after an admission for acute heart failure

2014

Abstract Background Traditionally, procalcitonin (PCT) is considered a diagnostic marker of bacterial infections. However, slightly elevated levels of PCT have also been found in patients with heart failure. In this context, it has been suggested that PCT may serve as a proxy for underrecognized infection, endotoxemia, or heightened proinflammatory activity. Nevertheless, the clinical utility of PCT in this setting is scarce. We aimed to evaluate the association between PCT and the risk of long-term outcomes. Methods and results We measured at admission PCT of 261 consecutive patients admitted for acute heart failure (AHF) after excluding active infection. Cox and negative binomial regressi…

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…

Length of stay and risk of very early readmission in acute heart failure

2016

In patients admitted for acute heart failure (AHF), optimal length of stay (LOS) remains controversial. Longer hospitalizations are associated with worse prognosis, but little is known about short hospitalizations. The aim of this work was to evaluate the relationship between LOS and the risk of short-term readmission in patients discharged after a hospitalization for AHF.We included 2110 consecutive patients. The independent associations between LOS and unplanned 10, 15 and 30-day readmissions were evaluated by Cox regression analysis adjusted for competing events. LOS was categorized as LOS1: ≤4days, LOS2: 5-7days, LOS3: 8-10days, and LOS4:10days.The mean age was 73±11years and 52.6% exhi…

Antigen carbohydrate 125 as a biomarker in heart failure: a narrative review.

2021

Congestion explains many of the signs and symptoms of acute heart failure (AHF) and disease progression. However, accurate quantification of congestion is challenging in daily practice. Antigen carbohydrate 125 (CA125) or mucin 16 (MUC16), a large glycoprotein synthesized by mesothelial cells, has emerged as a reliable proxy of congestion and inflammation in patients with heart failure. In AHF syndromes, CA125 is strongly associated with right-sided heart failure parameters and a higher risk of adverse clinical events beyond standard prognostic factors, including natriuretic peptides. Furthermore, CA125 has the potential for both monitoring and guide HF treatment following a decompensated H…

Effectiveness of the Relative Lymphocyte Count to Predict One-Year Mortality in Patients With Acute Heart Failure

2011

Several works have endorsed a significant role of the immune system and inflammation in the pathogenesis of heart failure. As indirect evidence, an association between a low relative lymphocyte count (RLC%) and worse outcomes found in this population has been suggested. Nevertheless, the role of RLC% for risk stratification in a large and nonselected population of patients with acute heart failure (AHF) has not yet been determined. Thus, the aim of this study was to determine the association between low RLC% and 1-year mortality in patients with AHF and consequently to define whether it has any role for early risk stratification. A total of 1,192 consecutive patients admitted for AHF were a…

Antigen carbohydrate 125 in heart failure: Not just a surrogate for serosal effusions?

2011

Wehave readwith interest the letter CA-125andheart failure:Deja vu or “still to be seen” by Topatan B and Basaran A [1] where the authors concisely reviewed the current pathophysiological knowledgeof CA125 in heart failure (HF). As discussed by these authors, the pathogenesis of this biomarker's elevation inHF is complex andmultifactorial,with apparently different driven forces. For instances, a proinflammatory stimulus (IL-1, tumour necrosis factor-α, lipopolysaccharide) and mesothelial-induced stress appear thekeymechanisms related to the increaseof this biomarker in HF [1–5]. However, no clear evidence exists in regard to how these two mechanisms differentially participate in CA-125 elev…
