Cardiac and extracardiac lipid metabolism is known to be significantly altered in the course of the heart failure with reduced ejection fraction (HF-REF), however the precise mechanisms are not fully elucidated. The aim of the study was to use of untargeted metabolomics to identify and validate changes in the blood metabolites profile, occurring as a result of HF-REF development. The analyses were performed first in the derivation set (36 chronic HF-REF patients and 19 controls without the disease) and repeated in validation cohort (31 chronic HF-REF patients and 20 controls)...

BACKGROUND: The designation of some cardiac-specific proteins as prognostic biomarkers in chronic obstructive pulmonary disease (COPD) exacerbations suggest that the process of exacerbation involves cardiomyocyte injury. Among these cardiac biomarkers, heart-type fatty acid binding protein (h-FABP) is considered a very sensitive diagnostic marker for cardiomyocyte injury and a prognostic marker in chronic heart failure. However, the prognostic usefulness of h-FABP in patients with COPD remains unclear...

This review article summarizes the relevant English literature on gout from 2010 through April 2017. It emphasizes that the current epidemiology of gout indicates a rising prevalence worldwide, not only in Western countries but also in Southeast Asia, in close relationship with the obesity and metabolic syndrome epidemics. New pathogenic mechanisms of chronic hyperuricaemia focus on the gut (microbiota, ABCG2 expression) after the kidney. Cardiovascular and renal comorbidities are the key points to consider in terms of management...

BACKGROUND AND AIMS: Elevated serum uric acid (sUA) concentrations have been associated with worse prognosis in heart failure (HF) but little is known about elderly patients. We aimed to assess long-term additive prognostic value of sUA in elderly patients hospitalized for HF. METHODS AND RESULTS: Clinical and echocardiographic characteristics of 310 consecutive elderly patients hospitalized for HF were collected. During index period, 206 had sUA concentrations available, which were obtained within 24 h prior to discharge; 10 patients were lost to follow-up, leaving 196 patients available...

BACKGROUND: The prognostic impact of hyperuricemia on long-term clinical outcomes in patients with chronic heart failure (HF) has been investigated in observational registries and clinical trials, but the results have been often inconclusive. We examined the prognostic impact of elevated serum uric acid levels on long-term clinical outcomes in the GISSI-HF (Gruppo Italiano per lo Studio della Sopravvivenza nella Insufficienza Cardiaca-Heart Failure) trial. METHODS: We assessed the rates of all-cause death, cardiovascular death, cardiovascular hospitalization and the composite of all-cause death or cardiovascular hospitalization over a median follow-up of 3...

The objective of the present study was to evaluate clinical implications of serum uric acid (UA) on the progression of heart failure with preserved ejection fraction (HFpEF) in hypertensive patients. A total of 1009 adult patients with left ventricular hypertrophy and suspected left ventricular diastolic dysfunction were enrolled at our hospital from January 2008 to December 2011. With a median follow-up of 7.2 years, 136 (13.2%) patients developed new-onset HFpEF and 151 (15.0%) had major adverse cardiovascular events (MACEs)...

BACKGROUND: Although a lot of studies have  shown serum uric acid (SUA) could be a marker of adverse prognosis in patients with acute myocardial infarction, the role of SUA as a risk factor for myocardial infarction is controversial. This study aimed to evaluate the association between hyperuricemia and short-term outcomes of elderly patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS: Six hundred and seventy-three elderly patients (≥ 60 years) were divided into high-SUA-level group (group H: N = 168) and low-SUA-level group (group L: N = 505) according to the SUA levels on admission...

OBJECTIVES: Accumulating evidence suggests a direct role of uric acid (UA) on left ventricular (LV) diastolic function in chronic kidney disease and heart failure (HF) patients. Recently, UA has been linked to LV hypertrophy (LVH) and diastolic dysfunction (DD) in women with preserved ejection fraction (pEF) but not in corresponding men. We sought to assess if UA could predict indices of DD in hypertensive subjects with pEF independently of gender. METHODS: We consecutively recruited 382 apparently healthy hypertensive subjects (age: 61...

The role of serum uric acid (SUA) as a prognostic marker for incident heart failure (HF) in hypertensive subjects is uncertain. We have prospectively examined the relationship between SUA and incident HF in 3440 men aged 60-79years separately in those on and not on antihypertensive treatment who were followed up for a mean period of 15years. Men on SUA lowering drugs and those with history of HF or myocardial infarction were excluded. There were 260 incident HF cases. The men were divided into three groups of SUA concentrations/levels (<350, 350-410 and >410μmol/L)...

AIMS: Elevated serum uric acid concentration (SUA) has been associated with an increased risk of cardiovascular disease, but this may be due to unmeasured confounders. We examined the association between SUA and outcomes as well as the effect of sacubitril/valsartan on SUA in patients with heart failure with reduced ejection fraction (HFrEF) in PARADIGM-HF. METHODS AND RESULTS: The association between SUA and the primary composite outcome of cardiovascular death or heart failure (HF) hospitalization, its components, and all-cause mortality was examined using Cox regression analyses among 8213 patients using quintiles (Q1-Q5) of SUA adjusted for baseline prognostic variables including estimated glomerular filtration rate (eGFR), diuretic dose, and log N-terminal pro-brain natriuretic peptide...

PURPOSE: Clinical guidelines recommend febuxostat as first-line pharmacologic urate-lowering therapy for patients with gout to achieve a goal serum uric acid (sUA) <6 mg/dL; however, little is known about other contributing factors. This study identified clinical characteristics of patients treated with febuxostat to develop and validate a predictive model for achieving a goal sUA. PATIENTS AND METHODS: Patients with Humana Medicare or commercial insurance, diagnosed with gout and newly initiated on febuxostat (index date February 1, 2009 - December 31, 2013), were identified for a retrospective cohort study...

BACKGROUND: Cardiac resynchronization therapy (CRT) in chronic heart failure has been shown to improve mortality and morbidity. However, comprehensive data are not available as concerns how circulating biomarkers reflecting different organ functions, such as serum uric acid, blood urea nitrogen (BUN), albumin, cholesterol, or various liver enzymes, change over time as a consequence of CRT. The aim of this prospective study was to overview these possible changes. METHODS: A total of 20 routine laboratory parameters were measured in 122 control subjects and in 129 patients with chronic heart failure before CRT, 6 months, and 2 years later...

The relation between uric acid (UA) and heart failure has been described; however, there is little detail concerning acute heart failure (AHF) in patients with reduced versus preserved ejection fraction heart failure (HFrEF, HFpEF). We studied 324 consecutive AHF patients screened from interventional Diur-HF Trial (NCT01441245) from January 2011 to February 2016, and divided into HFrEF (EF <50%) and HFpEF (EF ≥50%). We defined hyperuricemia as serum UA ≥7.0 mg/dL in men and ≥6 mg/dL in women. Patients were followed up for 6 months after discharge...

OBJECTIVE: Our study was to explore the roles between serum soluble suppression of tumorigenicity 2 (sST2) and N-terminal pro-brain natriuretic peptide (NT-proBNP) while evaluating ventricular function to properly diagnose chronic heart failure (CHF). METHODS: In total, 197 CHF patients were recruited and classified into ventricular function's II, III, and IV groups, and 106 healthy people into normal control group. To detect concentrations of Sst2 and NT-proBNP, ELISA and electro-chemiluminescence immuno assay were implemented...

Background Oxidative stress (OS) represents the primary mediator of chronic heart failure (CHF) development and progression. It is well established that homocysteine is able to generate reactive oxygen species. Small amounts of allantoin in human serum result from free radical action on urate and may provide a stable marker for in vivo free radical activity. To investigate whether some easily measurable indexes such as antioxidants (uric acid, glutathione) and related molecules (allantoin, homocysteine and cysteine) can serve as OS biomarkers...

Mean serum uric acid (SUA) levels are higher in men than women. In addition, recent studies have suggested that the SUA threshold at which the cardiovascular risk might increase may vary between women and men. In the current retrospective study, by analyzing the data from 219 female and 519 male patients who were free from uric acid-lowering medication, we investigated whether SUA is associated with left ventricular mass index (LVMI), left ventricular ejection fraction (LVEF), and plasma levels of B-type natriuretic peptide (BNP) independent of confounding factors, such as serum calcium, inorganic phosphate, and fibroblast growth factor 23 (FGF23), in a gender-specific manner...

Pulmonary hypertension due to heart failure with preserved ejection fraction (PH-HFpEF) has been poorly studied in patients with systemic sclerosis (SSc). We sought to compare clinical characteristics and survival of SSc patients with PH-HFpEF (SSc-PH-HFpEF) versus pulmonary arterial hypertension (SSc-PAH). We hypothesized that patients with SSc-PH-HFpEF have a similar poor overall prognosis compared with patients with SSc-PAH when matched for total right ventricular load. The analysis included 117 patients with SSc-PH (93 with SSc-PAH versus 24 with SSc-PH-HFpEF) enrolled prospectively in the Johns Hopkins PH Registry...
