Abstract
Aims: High uric acid (HUA), as a pro-oxidant, plays a significant role in the pathophysiology of cardiovascular disease. Studies have indicated that elevated uric acid levels can adversely affect cardiovascular health. Nevertheless, the impact of hyperuricemia on cardiomyopathy remains uncertain. Further research is needed to elucidate the relationship between HUA and cardiomyopathy, shedding light on its potential implications for heart health. Results: We demonstrated that uricase knockout (Uox-KO) mice accelerated the development of cardiomyopathy, causing significantly impaired cardiac function and myocardial fibrosis. Meanwhile, the mitochondrial morphology was destroyed, the lipid peroxidation products increased in number and the antioxidant function was weakened. In addition, we evaluated the effects of ferrostatin-1 (Fer-1), the ferroptosis inhibitor. Myocardial damage can be reversed by the Fer-1 treatment caused by HUA combined with doxorubicin (DOX) treatment. Benzbromarone, a uric acid-lowering drug, decreases myocardial fibrosis, and ferroptosis by alleviating hyperuricemia in Uox-KO mice by DOX administration. In vitro, we observed that the activity of cardiomyocytes treated with HUA combined with DOX decreased significantly, and lipid reactive oxygen species (ROS) increased significantly. Afterward, we demonstrated that HUA can promote oxidative stress in DOX, characterized by increased mitochondrial ROS, and downregulate protein levels of glutathione peroxidase 4 (GPX4). N-acetyl-l-cysteine, an antioxidant, inhibits the process by which HUA promotes DOX-induced ferroptosis by increasing the GPX4 expression. Innovation: We verified that HUA can exacerbate myocardial damage. This has clinical implications for the treatment of cardiac damage in patients with hyperuricemia. Conclusions: Our data suggested that HUA promotes the cardiomyopathy. HUA promotes DOX-induced ferroptosis by increasing oxidative stress and downregulating GPX4. Antioxid. Redox Signal. 00, 00-00.

Abstract
(1) Background: Left ventricular assist devices (LVADs) represent mechanical support in end-stage congestive heart failure and are characterized by satisfactory long-term results. Uric acid (UA) represents one of the early heart failure markers whose usefulness was postulated in clinical practice. (2) Methods: Twenty-nine male patients with a median age of 58 (51-62) years were referred for LVAD implantation due to end-stage congestive heart failure in the mean (SD) New York Heart Association (NYHA) status class 3.3 (0.6). Preoperative and postoperative right ventricular (RV) characteristics were compared with serum uric acid concentration within 12 (8-15) months following the implantation. (3) Results: Significant correlations between postoperative uric acid concentration and right ventricular dimension (r = 0.604, p = 0.005), tricuspid annulus plane systolic excursion (TAPSE) (r = -0.496, p = 0.022), left ventricular ejection fraction (r = -0.463, p = 0.046), and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) (r = 0.505, p = 0.041) were noted. (4) Conclusions: The analysis shows the association between the postoperative RV diameter and TAPSE results in LVAD patients and uric acid concentration. Serum uric acid can be regarded as a possible right ventricular dysfunction marker in LVAD patients.

Efficacy and safety of the urate-lowering agent febuxostat in chronic heart failure patients with hyperuricemia: results from the LEAF-CHF study. Heart Vessels 2024:10.1007/s00380-024-02448-9. [PMID: 39158751 DOI: 10.1007/s00380-024-02448-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 08/08/2024] [Indexed: 08/20/2024]
Abstract
Hyperuricemia is an independent predictor of mortality in patients with chronic heart failure (CHF). To determine whether febuxostat, a urate-lowering agent, may improve clinical outcomes in CHF patients, we conducted a multicenter, prospective, randomized, open-label, blinded endpoint study with a treatment period of 24 weeks. We randomly assigned Japanese outpatients diagnosed with both CHF with reduced left ventricular ejection fraction (LVEF < 40%) and asymptomatic hyperuricemia (serum uric acid [UA] levels > 7.0 mg/dl and < 10.0 mg/dl) to either a febuxostat group (n = 51) or a control group (n = 50). The primary efficacy endpoint was the change in log-transformed plasma B-type natriuretic peptide (BNP) levels from baseline to week 24 (or at discontinuation). The secondary efficacy endpoints were the changes in LV systolic or diastolic function evaluated by echocardiography, New York Heart Association (NYHA) class, hemoglobin, and estimated glomerular filtration rate from baseline to week 24, and the change in log-transformed plasma BNP levels or serum UA levels from baseline to weeks 4, 8, 12, 16 and 20 (BNP) or weeks 4, 8, 12, 16, 20 and 24 (serum UA). The primary safety endpoints were occurrence of all-cause death or major cardiovascular events. The mean age of participants was 70 years; 14% were female. The febuxostat group and the control group did not differ with respect to the primary efficacy endpoint (p = 0.13), although the decrease in log-transformed plasma BNP levels from baseline to each of weeks 4, 8, 12, 16 and 20 was greater in the febuxostat group. There were no significant differences between the two groups in the primary safety endpoints or the secondary efficacy endpoints except reduced serum UA levels in the febuxostat group. Febuxostat did not reduce plasma BNP levels at week 24 in patients with CHF, but it appeared safe with no increase in major cardiovascular events and all-cause or cardiovascular mortality.

Abstract
PURPOSE It is unclear whether preoperative serum uric acid (SUA) elevation may play a role in the development of acute kidney injury (AKI) associated with cardiac surgery (CSA-AKI). We conducted a cohort study to evaluate the influence of preoperative hyperuricemia on AKI in patients at high risk for developing SC-AKI. DESIGN Multicenter prospective international cohort study. SETTING Fourteen university hospitals in Spain and the United Kingdom. PARTICIPANTS We studied 261 consecutive patients at high risk of developing CSA-AKI, according to a Cleveland score ≥ 4 points, from July to December 2017. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS AKIN criteria were used for the definition of AKI. Multivariable logistic regression models and propensity score-matched pairwise analysis were used to determine the adjusted association between preoperative hyperuricemia (≥7 mg/dL) and AKI. Elevated preoperative AUS (≥7 mg/dL) was present in 190 patients (72.8%), whereas CSA-AKI occurred in 145 patients (55.5%). In multivariable logistic regression models, hyperuricemia was not associated with a significantly increased risk of AKI (adjusted Odds Ratio [OR]: 1.58; 95% confidence interval [CI]: 0.81-3; P = .17). In propensity score-matched analysis of 140 patients, the hyperuricemia group experienced similar adjusted odds of AKI (OR 1.05, 95%CI 0.93-1.19, P = .37). CONCLUSIONS Hyperuricemia was not associated with an increased risk of AKI in this cohort of patients undergoing cardiac surgery at high risk of developing CSA-AKI.

Abstract
BACKGROUND Hypoalbuminemia is common in heart failure (HF) patients; however, there are no data regarding the possible long-term prognostic role of serum albumin (SA) in the younger population with chronic HF without malnutrition. The aim of this study was to examine the long-term prognostic role of SA levels in predicting major adverse cardiac events (MACE) in middle-aged outpatients with chronic HF. METHODS In the present retrospective analysis, 378 subjects with HF were enrolled. MACE (non-fatal ischemic stroke, non-fatal myocardial infarction, cardiac revascularization or coronary bypass surgery, and cardiovascular death), total mortality, and HF hospitalizations (hHF) occurrence were evaluated during a median follow-up of 6.1 years. RESULTS In all population, 152 patients had a SA value < 3.5 g/dL and 226 had a SA value ≥ 3.5 g/dL. In patients with SA ≥ 3.5 g/dL, the observed MACE were 2.1 events/100 patient-year; while in the group with a worse SA levels, there were 7.0 events/100 patient-year (p < 0.001). The multivariate analysis model confirmed that low levels of SA increase the risk of MACE by a factor of 3.1. In addition, the presence of ischemic heart disease, serum uric acid levels > 6.0 mg/dL, chronic kidney disease, and a 10-year age rise, increased the risk of MACE in study participants. Finally, patients with SA < 3.5 g/dl had a higher incidence of hHF (p < 0.001) and total mortality (p < 0.001) than patients with SA ≥ 3.5 g/dl. CONCLUSIONS Patients with chronic HF that exhibits low SA levels show a higher risk of MACE, hHF and total mortality.

Abstract
The platelet/high-density lipoprotein ratio (PHR) has been identified as a significant indicator of inflammation and a hypercoagulable state, demonstrating a strong link with the severity of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS). However, its correlation with hyperuricemia has not yet been documented. This study utilized a cross-sectional design, analyzing data collected from the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2016 in the United States. The platelet/high-density lipoprotein ratio (PHR) was determined by dividing the number of platelets (PLT) by the level of high-density lipoprotein cholesterol (HDL-C). We employed multivariable logistic regression analyses, generalized additive models, and subgroup analyses to investigate the correlation between PHR and hyperuricemia. The study revealed a hyperuricemia prevalence of 18.56%. Analysis indicated a significant positive correlation between PHR and the risk of hyperuricemia (OR 1.11, 95% CI 1.08, 1.14). This correlation remained consistent across different subgroups including age, ethnicity, gender, and body mass index (BMI). Smooth curve fitting demonstrated a saturation effect between PHR and the risk of hyperuricemia. PHR is positively correlated with hyperuricemia and may serve as a novel biomarker for predicting the onset of this condition. Additionally, targeted interventions to improve PHR might help reduce the incidence of hyperuricemia.

Abstract
Heart failure (HF) remains a major medical and social problem. The NT-pro-brain natriuretic peptide (NT-proBNP) and its active form, brain-type natriuretic peptide (BNP), in a simple blood test are the gold-standard biomarkers for HF diagnosis. However, even good biomarkers such as natriuretic peptides fail to predict all the risks associated with HF due to the diversity of the mechanisms involved. The pathophysiology of HF is determined by numerous factors, including oxidative stress, inflammation, neuroendocrine activation, pathological angiogenesis, changes in apoptotic pathways, fibrosis and vascular remodeling. High readmission and mortality rates prompt a search for new markers for the diagnosis, prognosis and treatment of HF. Oxidative-stress-mediated inflammation plays a crucial role in the development of subsequent changes in the failing heart and provides a new insight into this complex mechanism. Oxidative stress and inflammatory biomarkers appear to be a promising diagnostic and prognostic tool in patients with HF. This systematic review provides an overview of the current knowledge about oxidative stress and inflammation parameters as markers of HF.

Abstract
A role for inflammation in the development and progression of heart failure (HF) has been proposed for decades. Multiple studies have demonstrated the potential involvement of several groups of cytokines and chemokines in acute and chronic HF, though targeting these pathways in early therapeutic trials have produced mixed results. These studies served to highlight the complexity and nuances of how pro-inflammatory pathways contribute to the pathogenesis of HF. More recent investigations have highlighted how inflammation may play distinct roles based on HF syndrome phenotypes, findings that may guide the development of novel therapies. In this review, we propose a contemporary update on the role of inflammation mediated by the innate and adaptive immune systems with HF, highlighting differences that exist across the ejection fraction spectrum. This will specifically be looked at through the lens of established and novel biomarkers of inflammation. Subsequently, we review how improvements in inflammatory pathways may mediate clinical benefits of existing guideline-directed medical therapies for HF, as well as future therapies in the pipeline targeting HF and inflammation.

Abstract
The cardiovascular (CV) safety of febuxostat compared to allopurinol for the treatment of hyperuricemia among Asian patients is uncertain. In this study, we conducted a systematic review and meta-analysis to compare the CV safety profiles of febuxostat with allopurinol in Asian patients with hyperuricemia. A total of 13 studies were included. On the basis of the pooled results of cohort studies, febuxostat users were at a significantly higher risk for acute coronary syndrome (ACS; hazard ratio [HR]: 1.06, 95% confidence interval [CI]: 1.03-1.09, p < 0.01), atrial fibrillation (HR: 1.19, 95% CI: 1.05-1.35, p < 0.01) than allopurinol users, whereas no significant difference between febuxostat and allopurinol existed for urgent coronary revascularization (HR: 1.07, 95% CI: 0.98-1.16, p = 0.13), and stroke (HR: 0.96, 95% CI: 0.91-1.01, p = 0.13). Nevertheless, that difference in results of acute decompensated heart failure (ADHF; HR: 0.73, 95% CI: 0.35-1.53, p = 0.40) and all-cause death (HR = 0.86, 95% CI: 0.49-1.51, p = 0.60) was not significant based on randomized controlled trials. In the Chinese subgroup, febuxostat could increase the risk of ADHF (HR: 1.22, 95% CI: 1.01-1.48, p < 0.05), CV death (HR: 1.25, 95% CI: 1.03-1.50, p < 0.05), and all-cause mortality (HR: 1.07, 95% CI: 1.01-1.14, p < 0.05) compared to allopurinol. In conclusion, the use of febuxostat, compared with allopurinol among Asian patients, was associated with a significantly increased risk of adverse CV events.

Abstract
AIMS This systematic review and meta-analysis aimed to investigate the association between serum uric acid (SUA) levels and the incidence rate and prognosis of heart failure (HF), as well as the impact of uric acid-lowering treatment on HF patients. METHODS AND RESULTS PubMed and Embase were searched for original articles reporting on the association between SUA and HF incidence, adverse outcomes, and the effect of uric acid-lowering treatment in HF patients. Data were pooled using random effects or fixed effects models. Univariable meta-regression analysis assessed the influence of study characteristics on research outcomes. Statistical analyses were conducted using RevMan software and STATA software version 15.0. Eleven studies on HF incidence and 24 studies on adverse outcomes in HF patients were included. Higher SUA levels were associated with an increased risk of HF (RR: 1.81, 95% CI: 1.53-2.16), all-cause mortality (RR: 1.44, 95% CI: 1.25-1.66), cardiac death (RR: 1.56, 95% CI: 1.32-1.84), and HF rehospitalization (RR: 2.07, 95% CI: 1.37-3.13) in HF patients. Uric acid-lowering treatment was found to increase all-cause mortality in HF patients (RR: 1.15, 95% CI: 1.05-1.25). CONCLUSIONS Uric acid is an independent predictor of heart failure occurrence and adverse prognosis. Targeting uric acid lowering as a therapeutic intervention does not improve the prognosis of patients with heart failure. It may not be advisable to use traditional urate-lowering drugs in young patients with heart failure, and elderly patients should exercise caution when using them.

Abstract
Hyperuricemia is implicated in numerous pathologies, but the mechanisms underlying uric acid production are poorly understood. Using a combination of mouse studies, cell culture studies, and human serum samples, we sought to determine the cellular source of uric acid. In mice, fasting and glucocorticoid treatment increased serum uric acid and uric acid release from ex vivo-incubated skeletal muscle. In vitro, glucocorticoids and the transcription factor FoxO3 increased purine nucleotide degradation and purine release from differentiated muscle cells, which coincided with the transcriptional upregulation of AMP deaminase 3, a rate-limiting enzyme in adenine nucleotide degradation. Heavy isotope tracing during coculture experiments revealed that oxidation of muscle purines to uric acid required their transfer from muscle cells to a cell type that expresses xanthine oxidoreductase, such as endothelial cells. Last, in healthy women, matched for age and body composition, serum uric acid was greater in individuals scoring below average on standard physical function assessments. Together, these studies reveal skeletal muscle purine degradation is an underlying driver of uric acid production, with the final step of uric acid production occurring primarily in a nonmuscle cell type. This suggests that skeletal muscle fiber purine degradation may represent a therapeutic target to reduce serum uric acid and treat numerous pathologies.

Abstract
Several studies have shown that an association exists between hyperuricemia and heart failure. Despite several innovative management strategies, heart failure is a significant cause of mortality worldwide. Hyperuricemia in heart failure patients leads to poorer outcomes. Additionally, hyperuricemia can be a strong surrogate marker for increased oxidative stress in heart failure patients. This oxidative stress leads to vascular endothelial damage and is linked to worsening heart failure and subsequent mortality. Hence, the measurement of serum uric acid levels in these patients can predict the present and future risk of complications of heart failure. Despite this knowledge, serum uric acid levels are not usually followed up in heart failure patients. This systematic review aims to give additional clarity to this association. We used research from the last twenty years (2002 to 2022) obtained from databases such as PubMed, PubMed Central (PMC), Google Scholar, and Science Direct. We used the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) 2020 guidelines. We removed duplicates, screened articles on the basis of title and abstract, applied eligibility criteria, and performed quality appraisal. Eventually, 15 articles were selected for review. There were 12 observational studies, two randomized controlled trials, and one meta-analysis. Our review showed that serum uric acid elevation is associated with the severity and complications of congestive heart failure. Serum uric acid can serve as a useful surrogate marker of oxidative stress in congestive heart failure (CHF) patients. The role of xanthine oxidase inhibitors needs to be evaluated further in CHF patients.

Abstract
Purpose Uric acid serves as a marker for cardiovascular risk and is often linked to inflammation and oxidative stress. There is evidence suggesting an association between uric acid and atrial fibrillation (AF), including its severity and occurrence of crises, as well as its involvement in cardiovascular mechanisms. The objective of this study was to assess the correlation between hyperuricemia and echocardiographic features in patients with chronic AF lasting for more than 5 years. Methods This case-control study involved 107 patients diagnosed with chronic non-valvular AF. Uric acid levels were measured in all patients, and they were divided into two groups: the first group consisted of 66 patients with hyperuricemia (>7.2 mg/dL), while the second group included 41 patients with normal uric acid levels. Echocardiography (TTE) was performed to evaluate each patient. Various clinical and echocardiographic parameters, such as left ventricle telediastolic (LVTDD) and telesystolic (LVTSD) diameters, left atrial diameter (LAD), aortic diameter (AoD), ejection fraction (EF), and pulmonary artery pressure (PAP), were analyzed. Results Binary logistic regression analysis revealed a statistically significant relationship between uric acid levels (>7.2 mg/dL) and LAD. For each unit increase in LAD, the probability of having hyperuricemia increased by 9% [odds ratio (OD): 0.91, 95% confidence interval (CI): 0.84-0.99]. A significant relationship was found between uric acid levels (>8 mg/dL) and LVESD (p = 0.045) as well as PAP (p = 0.006). For every unit increase in LVESD, the likelihood of having uric acid levels greater than 8 mg/dL increased by 22% [OD: 0.82, 95% CI: 0.67-0.99, b = -0.2]. Likewise, for each unit increase in PAP, the probability of having uric acid levels greater than 8 mg/dL was 9.4% [OD: 0.91, 95% CI: 0.86-0.97, b = -0.09]. Conclusions This study demonstrates that hyperuricemia has a significant relationship with the development of atrial remodeling, with an important association observed between hyperuricemia and an increase in left atrial diameter. Hyperuricemia is also correlated with an enlargement of the left ventricle end-systolic diameter and pulmonary artery pressure, showing a possible influence that hyperuricemia might have also left ventricle morphology and right ventricle function.

Abstract
A direct relationship between serum uric acid levels and hypertension, cardiovascular, renal and metabolic diseases has been reported in many basic and epidemiological studies. Among these, high blood pression is one of the most common features associated with hyperuricemia. In this regard, several small-scale interventional studies have demonstrated a significant reduction in blood pressure in hypertensive or prehypertensive patients on uric acid-lowering drugs. These observation or intervention studies have led to affirm that there is a causal relationship between uric acid and hypertension. While the clinical association between uric acid and high blood pressure is notable, no clear conclusion has yet been reached as to whether lowering uric acid is beneficial to prevent cardiovascular and renal metabolic diseases. Recently, several prospective randomized controlled intervention trials using allopurinol and other uric acid-lowering drugs have been reported, and the results from these trials were almost negative, suggesting that the correlation between hyperuricemia and cardiovascular disease has no causality. However, it is important to note that in some of these recent studies there were high dropout rates and an important fraction of participants were not hyperuricemic. Therefore, we should carry caution in interpreting the results of these studies. This review article presents the results of recent clinical trials using uric acid-lowering drugs, focusing on hypertension and cardiovascular and renal metabolic diseases, and discusses the future of uric acid therapy.

Abstract
Asymptomatic hyperuricaemia (HU) is considered a pathogenic factor in multiple disease contexts, but a causative role is only proven for the crystalline form of uric acid in gouty arthritis and urate nephropathy. Epidemiological studies document a robust association of HU with hypertension, cardiovascular disease (CVD) and CKD progression, but CKD-related impaired uric acid (UA) clearance and the use of diuretics that further impair UA clearance likely accounts for these associations. Interpreting the available trial evidence is further complicated by referring to xanthine oxidase inhibitors as urate-lowering treatment, although these drugs inhibit other substrates, so attributing their effects only to HU is problematic. In this review we provide new mechanistic insights into the biological effects of soluble and crystalline UA and discuss clinical evidence on the role of asymptomatic HU in CKD, CVD and sterile inflammation. We identify research areas with gaps in experimental and clinical evidence, specifically on infectious complications that represent the second common cause of death in CKD patients, referred to as secondary immunodeficiency related to kidney disease. In addition, we address potential therapeutic approaches on how and when to treat asymptomatic HU in patients with kidney disease and where further interventional studies are required.

Abstract
It is not clear to date whether a first admission in heart failure (HF) marks a worse evolution in patients not previously diagnosed with HF ("de novo HF") than those already diagnosed as outpatients ("acutely decompensated HF"). The aim of the study was to analyze whether survival in patients admitted for de novo HF differs from the survival in those admitted for a first episode of decompensation but with a previous diagnosis of HF. This study includes an analysis of 1,728 patients admitted for decompensated HF during 9 years. Readmissions and patients with left ventricular ejection fraction ≥50% were excluded (finally, 524 patients analyzed). We compared de novo HF (n = 186) in patients not diagnosed with HF, although their structural heart disease was defined, versus acutely decompensated HF (n = 338). The clinical profiles in both groups were similar. The de novo HF group more frequently presented with normal right ventricular function, with less presence of severe tricuspid regurgitation. The probability of survival was low in both groups. Thus, the median life in the de novo HF group was 2.1 years and in the acutely decompensated HF group, 3.5 years. There was a lower probability of long-term survival in the de novo HF group (p = 0.035). The variables associated with mortality were age (p <0.0001), ischemic heart disease (p <0.0001), hypertension (p = 0.009), obesity (p = 0.025), diabetes (p = 0.001), and N-terminal pro-brain natriuretic peptide at admission (p <0.0001). A higher glomerular filtration rate was associated with better survival (p = 0.033). De novo HF was associated with a higher mortality than chronic HF with acute decompensation (hazard ratio 1.53, 95% confidence interval 1.03 to 2.27, p = 0.036). In conclusion, the first admission for HF decompensation in patients with no previous diagnosis of HF identifies a subgroup of patients with higher long-term mortality.

Abstract
BACKGROUND Serum uric acid (SUA) is activated in catabolic, hypoxic, and inflammatory conditions characteristic of heart failure (HF) and is a source of reactive oxygen species. Losartan is unique among other angiotensin receptor blockers in reducing SUA. OBJECTIVES To study the patient characteristics and outcome associations by SUA levels, as well as the effect of high- vs. low-dose losartan on SUA levels in HF. METHODS HEAAL was a double-blind trial, comparing the effect of two doses of losartan 150 (high dose) vs. 50 (low dose) mg/day among 3834 patients with symptomatic HF, a left ventricular ejection fraction≤40 %, and known intolerance to angiotensin-converting enzyme inhibitors. In the present study, we studied the associations of SUA with outcomes and the effect of high- vs. low-dose losartan on SUA levels, incident hyperuricemia, and gout. RESULTS Patients with higher SUA had more comorbidities, worse renal function, were more symptomatic, used diuretics more frequently, and were 1.5- to 2-fold more likely to experience HF hospitalizations and cardiovascular death. The benefit of high-dose losartan to improve HF outcomes was not influenced by baseline SUA levels (interaction p > 0.1). Compared with low-dose, high-dose losartan reduced SUA by -0.27 (-0.34 to -0.21) mg/dL, p < 0.001. The incidence of hyperuricemia was reduced with high-dose losartan, but the incidence of gout was not. CONCLUSIONS In HEAAL, hyperuricemia was associated with worse outcomes. High-dose losartan reduced SUA and hyperuricemia more than low-dose and the cardiovascular benefits of high-dose losartan were not modified by SUA levels.

Abstract
BACKGROUND The data on clinical characteristics, treatment practices and out comes in patients with Non- ischemic Systolic Heart Failure (NISHF) is limited. We report clinical characteristics, treatment and outcomes in patients with NISHF. METHODS 1004 patients with NISHF were prospectively enrolled and their demographics, clinical characteristics, and treatment were recorded systematically. Patients were followed annually for a median of 3 years (1 year to 8 years) for allcause death, major adverse cardiovascular events (MACE); composite of all-cause death, hospitalization of heart failure, and or for stroke. RESULTS Patients of NISHF were middle-aged (58.8±16.2 years) population with severely depressed left ventricular ejection fraction (29.3±7.02%) and 31.1% had symptoms of advanced Heart failure. Hypertension (43.6%), obesity and or overweight (28.0%), Diabetes (15.0%), and valvular heart disease (11.8%) were the common risk factors. The guideline directed medical treatment was prescribed in more than 80% of the study cohort. Incidence of all cause death and MACE was 7 (6.8, 8.8) per 100 person years and 11(10, 13) per 100 person years respectively. The cumulative incidence of deaths and MACE was 35% (30%, 40%) and 49% (44%, 53%) at 8 years of follow-up. CONCLUSIONS Patients of NISHF were middle-aged population with severely depressed LV systolic function with significant incident morbidity and mortality. Early detection of risk factors and their risk management and enhancing the use of guideline directed treatment may improve the outcomes.

Abstract
Oxidative stress (OS) is mediated by reactive oxygen species (ROS), which in cardiovascular and other disease states, damage DNA, lipids, proteins, other cellular and extra-cellular components. OS is both initiated by, and triggers inflammation, cardiomyocyte apoptosis, matrix remodeling, myocardial fibrosis, and neurohumoral activation. These have been linked to the development of heart failure (HF). Circulating biomarkers generated by OS offer potential utility in patient management and therapeutic targeting. Novel OS-related biomarkers such as NADPH oxidases (sNox2-dp, Nrf2), advanced glycation end-products (AGE), and myeloperoxidase (MPO), are signaling molecules reflecting pathobiological changes in HF. This review aims to evaluate current OS-related biomarkers and their associations with clinical outcomes and to highlight those with greatest promise in diagnosis, risk stratification and therapeutic targeting in HF.

Optimal uric acid reduction to improve vascular endothelial function in patients with chronic heart failure complicated by hyperuricemia. Hypertens Res 2023; 46:688-696. [PMID: 36539463 DOI: 10.1038/s41440-022-01116-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 10/16/2022] [Indexed: 12/24/2022]
Abstract
Although an association of serum uric acid levels with endothelial function has been shown in various clinical settings, the optimal treatment target that would benefit vascular endothelial function has not been established. We, therefore, conducted a post hoc analysis of the Excited-UA study to identify an optimal target. Patients (N = 133) with chronic heart failure and comorbid hyperuricemia who enrolled in the Excited-UA study were divided into three tertiles based on their serum uric acid level 24 weeks after initiating xanthine oxidase inhibitor treatment with topiroxostat or allopurinol (i.e., groups with low, moderate, and high uric acid levels). Flow-mediated dilation (FMD) and reactive hyperemia index (RHI) values measured by reactive hyperemia peripheral arterial tonometry (RH-PAT) were compared among groups. The change from baseline in the FMD value 24 weeks after treatment was comparable among the three groups. In contrast, the change from baseline in the RHI was significantly different among the three groups (-0.153 ± 0.073, 0.141 ± 0.081 and -0.103 ± 0.104 in the low, moderate, and high uric acid level groups, respectively, P = 0.032). After adjustment for age, body mass index, and concomitant use of diuretics, which differed among the three groups, the change in the RHI in the moderate uric acid level group tended to be higher than that in the high uric acid level group (P = 0.057) and was significantly higher than that in the low uric acid level group (P = 0.020). These results indicate that targeting excessively low uric acid levels by treatment with xanthine oxidase inhibitors might be less beneficial for improving microvascular endothelial function in patients with chronic heart failure. Comparisons of the changes from baseline in vascular endothelial function parameters at 24 weeks among the 3 groups of low, moderae and high uric acid levels achieved with xanthine oxidase inhibitors. After adjustment for confounding factors, such as age, body mass index and concomitant diuretic use, which showed differences among the 3 groups, the change in RHI in the moderate uric acid level group tended to be higher than that in the high uric acid level group and was significantly higher than that in the low uric acid level group.

Risk factor structure of heart failure in patients with cancer after treatment with anticancer agents' assessment by big data from a Japanese electronic health record. Heart Vessels 2023; 38:793-802. [PMID: 36705672 PMCID: PMC10182140 DOI: 10.1007/s00380-023-02238-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 01/18/2023] [Indexed: 01/28/2023]
Abstract
As the prognosis of cancer patients has been improved, comorbidity of heart failure (HF) in cancer survivors is a serious concern, especially in the aged population. This study aimed to examine the risk factors of HF development after treatment by anticancer agents, using a machine learning-based analysis of a massive dataset obtained from the electronic health record (EHR) in Japan. This retrospective, cohort study, using a dataset from 2008 to 2017 in the Diagnosis Procedure Combination (DPC) database in Japan, enrolled 140,327 patients. The structure of risk factors was determined using multivariable analysis and classification and regression tree (CART) algorithm for time-to-event data. The mean follow-up period was 1.55 years. The prevalence of HF after anticancer agent administration were 4.0%. HF was more prevalent in the older than the younger. As the presence of cardiovascular diseases and various risk factors predicted HF, CART analysis of the risk factors revealed that the risk factor structures complicatedly differed among different age groups. The highest risk combination was hypertension, diabetes mellitus, and atrial fibrillation in the group aged ≤ 64 years, and the presence of ischemic heart disease was a key in both groups aged 65-74 years and 75 ≤ years. The machine learning-based approach was able to develop complicated HF risk structures in cancer patients after anticancer agents in different age population, of which knowledge would be essential for realizing precision medicine to improve the prognosis of cancer patients.

Abstract
This study aimed to investigate the adverse effects of serum uric acid concentration on the severity of chronic congestive heart failure. One hundred patients with chronic congestive heart failure (several risk factors include hypertension, smoking, and diabetes mellitus) were enrolled in this study (51 females and 49 males). Participants were admitted to Alsader Medical City in Al-Najaf from August 2018 to March 2019. Detailed medical history and complete clinical examination were performed for all patients. The patients' ages ranged from 13-90 years, with a mean of 62.1±15.8 years, and the median was 65 years. No statistically significant age difference was observed between males and females (P-value=0.687). Increased serum uric acid had a directly negative effect on the severity of chronic congestive heart failure and hypertension. High serum uric acid concentration was associated with increased severity of chronic congestive heart failure class NYHA III and NYHA IV and a decrement in ejection fraction of the left ventricle.

Abstract
BackgroundCurrent predictive models based on biomarkers reflective of different pathways of heart failure with reduced ejection fraction (HFrEF) pathogenesis constitute a useful tool for predicting death risk among HFrEF patients. The purpose of the study was to develop a new predictive model for post-discharge mortality risk among HFrEF patients, based on a combination of clinical patients’ characteristics, N-terminal pro-B-type Natriuretic peptide (NT-proBNP) and oxidative stress markers as a potentially valuable tool for routine clinical practice.Methods116 patients with stable HFrEF were recruited in a prospective single-center study. Plasma levels of NT-proBNP and oxidative stress markers [superoxide dismutase (SOD), glutathione peroxidase (GPX), uric acid (UA), total bilirubin (TB), gamma-glutamyl transferase (GGT) and total antioxidant capacity (TAC)] were measured in the stable predischarge condition. Generalized linear model (GLM), random forest and extreme gradient boosting models were developed to predict post-discharge mortality risk using clinical and laboratory data. Through comprehensive evaluation, the most performant model was selected.ResultsDuring a median follow-up of 525 days (7–930), 33 (28%) patients died. Among the three created models, the GLM presented the best performance for post-discharge death prediction in HFrEF. The predictors included in the GLM model were age, female sex, beta blockers, NT-proBNP, left ventricular ejection fraction (LVEF), TAC levels, admission systolic blood pressure (SBP), angiotensin-converting enzyme inhibitors/angiotensin receptor II blockers (ACEI/ARBs) and UA levels. Our model had a good discriminatory power for post-discharge mortality [The area under the curve (AUC) = 74.5%]. Based on the retained model, an online calculator was developed to allow the identification of patients with heightened post-discharge death risk.ConclusionIn conclusion, we created a new and simple tool that may allow the identification of patients at heightened post-discharge mortality risk and could assist the treatment decision-making.

Abstract
Background An association between uric acid (UA) and cardiovascular diseases, including heart failure (HF), has been reported. However, whether UA is a causal risk factor for HF is controversial. In particular, the prognostic value of lowering UA in patients with HF with preserved ejection fraction (HFpEF) is unclear. Methods and Results We enrolled patients with HFpEF from the PURSUIT‐HFpEF (Prospective Multicenter Observational Study of Patients With Heart Failure With Preserved Ejection Fraction) registry. We investigated whether UA was correlated with the composite events, including all‐cause mortality and HF rehospitalization, in patients with hyperuricemia and HFpEF (UA >7.0 mg/dL). Additionally, we evaluated whether lowering UA for 1 year (≥1.0 mg/dL) in them reduced mortality or HF rehospitalization. We finally analyzed 464 patients with hyperuricemia. In multivariable Cox regression analysis, UA was an independent determinant of composite death and rehospitalization (hazard ratio [HR], 1.15 [95% CI, 1.03–1.27], P=0.015). We divided them into groups with severe and mild hyperuricemia according to median estimated value of serum UA (8.3 mg/dL). Cox proportional hazards models revealed the incidence of all‐cause mortality was significantly higher in the group with severe hyperuricemia than in the group with mild hyperuricemia (HR, 1.73 [95% CI, 1.19–2.25], P=0.004). The incidence of all‐cause mortality was significantly decreased in the group with lowering UA compared with the group with nonlowering UA (HR, 1.71 [95% CI, 1.02–2.86], P=0.041). The incidence of urate‐lowering therapy tended to be higher in the group with lowering UA than in the group with nonlowering UA (34.9% versus 24.6%, P=0.06). Conclusions UA is a predictor for the composite of all‐cause death and HF rehospitalization in patients with hyperuricemia and HFpEF. In these patients, lowering UA, including the use of urate‐lowering therapy, may improve prognosis.

Biomakers in Chronic Chagas Cardiomyopathy. Microorganisms 2022; 10:microorganisms10081602.

Abstract
The primary objective was to observe the relationship between serum levels of BNP, Ca-125, C-reactive protein and uric acid as prognostic and functional markers in patients with chronic Chagas cardiomyopathy (CCC). Circulating levels of cytokines: IL-1β, TNFα, IL-10, IL6, IL-8 and IL-12 were determined and investigated regarding their association with hemodynamic parameters, clinical signs of heart failure and outcome. Chagas is still a neglected disease that affects numerous individuals, many of them in their most productive years. CCC with left ventricular dysfunction is the most severe presentation of Chagas Disease. BNP is a well-recognized prognostic and clinical biomarker, not only in chronic heart failure patients but also in patients with CCC. Previous studies have shown Ca-125, C-reactive protein, and uric acid to be potentially good prognostic markers in heart failure (HF). Fifty patients with left ventricular fraction less (LVEF) than 55% were selected and followed for a mean period of 18 ± 8.3 months. Patient’s mean age was 43.42 ± 10.3 years (32 male), their BNP was 293 (160–530) pg/mL, Ca-125 8.5 (5.5–16.75) U/mL, uric acid 6.2 ± 2 mg/dL, and C- reactive protein 4.5 (4.5–7.3) mg/L. Patients who had LVEF less than 35% had higher BNP (p = 0.0023), Ca-125 (p = 0.027) and uric acid (p = 0.01) serum levels. Patients who died also showed higher BNP (p = 0.01), uric acid (p = 0.05) and a trend towards higher Ca-125 serum levels (p = 0.056). All markers: BNP, Ca-125, uric acid and C-reactive had good predictability of death in Cox-regression univariate analysis, however, not on the final multivariate model. Of the inflammatory cytokines, IL-8 and IL-12 showed a relation to LVEF of less than 35%. IL-12 was related to adverse cardiovascular events and non-survival. IL-1β was a good predictor of mortality in the final Cox regression model. Determination of Ca-125, uric acid levels and C-reactive protein may add useful clinical and prognostic information and may help clinical decision making for patients with CCC.

Abstract
Background The sodium-glucose cotransporter-2 inhibitor empagliflozin decreases the risk of cardiovascular death or hospitalization for heart failure (HF) in patients with HF with reduced ejection fraction. Empagliflozin reduces serum uric acid (SUA), but the relevance of this effect in patients with HF is unclear. This study aimed to investigate the effect of empagliflozin on SUA levels and the therapeutic efficacy of empagliflozin in relation to SUA. Methods The association between SUA and the composite primary outcome of cardiovascular death or hospitalization for worsening HF, its components, and all-cause mortality was investigated in 3676 patients of the EMPEROR-Reduced trial (98.6% of the study cohort). The treatment effect of empagliflozin was studied in relation to SUA as continuous variable, to clinical hyperuricaemia (SUA >5.7 mg/dL for women, >7.0 mg/dL for men) and in subgroups of patients of tertiles of SUA. Results Hyperuricaemia was prevalent in 53% of patients with no sex differences. Elevated SUA (highest tertile, mean SUA 9.38 ± 1.49 mg/dL) was associated with advanced severity of HF and with worst outcome [composite outcome, hazard ratio (HR) 1.64 (95% confidence interval, CI 1.28–2.10); cardiovascular mortality, HR 1.98 (95% CI 1.35–2.91); all-cause mortality, HR 1.8 (95% CI 1.29–2.49), all P < 0.001] in multivariate adjusted analyses, as compared with the lowest tertile. SUA was reduced following treatment with empagliflozin at 4 weeks (vs. placebo: −1.12 ± 0.04 mg/dL, P < 0.0001) and remained lower throughout follow-up, with a similar reduction in all prespecified subgroups. Empagliflozin reduced events of clinically relevant hyperuricaemia (acute gout, gouty arthritis or initiation of anti-gout therapy) by 32% [HR 0.68 (95% CI 0.52–0.89), P = 0.004]. The beneficial effect of empagliflozin on the primary endpoint was independent of baseline SUA [HR 0.76 (95% CI 0.65–0.88), P < 0.001) and of the change in SUA at 4 weeks [HR 0.81 (95% CI 0.69–0.95), P = 0.012]. As a hypothesis-generating finding, an interaction between SUA and treatment effect suggested a benefit of empagliflozin on mortality (cardiovascular and all-cause mortality) in patients in elevated SUA (P for interaction = 0.005 and = 0.011, respectively). Conclusion Hyperuricaemia is common in HF and is an independent predictor of advanced disease severity and increased mortality. Empagliflozin induced a rapid and sustained reduction of SUA levels and of clinical events related to hyperuricaemia. The benefit of empagliflozin on the primary outcome was observed independently of SUA.

Mohd Ghazi A, Teoh CK, Abdul Rahim AA. Patient profiles on outcomes in patients hospitalized for heart failure: a 10-year history of the Malaysian population. ESC Heart Fail 2022; 9:2664-2675. [PMID: 35652407 PMCID: PMC9288813 DOI: 10.1002/ehf2.13992] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 04/14/2022] [Accepted: 05/08/2022] [Indexed: 11/15/2022] Open
Abstract
Aims Heart failure (HF) affects an estimated 38 million people worldwide and is the leading cause of hospitalization among adults and the elderly. Evidence suggests that there may be regional and ethnic differences in the prevalence, outcomes and management of HF. The aim of this study was to understand the disease burden and treatment patterns of patients hospitalized for HF in multi‐ethnic Malaysia. Methods and results A retrospective, non‐interventional study was conducted utilizing 10 years of medical records from the National Heart Institute Malaysia (IJN) from 1 January 2009 to 31 December 2018. Of the 4739 patients in the IJN database, 3923 were eligible and were included in this analysis. The study recorded a high male prevalence (72.3%) with a mean age of 62.0 (±13.26) years. The 30‐day and 1‐year rehospitalization rate was 6.8% and 24.7%, respectively. In‐hospital mortality was 7.2% with 27.0% due to cardiovascular causes and 14.2% non‐cardiovascular causes. The 30‐day and 1‐year rehospitalization rates were significantly higher in patients with lower systolic blood pressure (SBP, P < 0.001 and P = 0.002), diastolic blood pressure (DBP, P < 0.001 and P = 0.017), sodium (P < 0.001 and P = 0.029) and estimated glomerular filtration rate (eGFR, P < 0.001 and P = 0.002) and higher urea (P < 0.001 for both), serum creatinine (P < 0.001 and P = 0.003), and uric acid (P < 0.001 for both), respectively. Risk of hospitalization within 1 year varied significantly by ethnicity and was relatively higher in Indian (28.3%), followed by Malay (24.4%) and Chinese (21.9%; P = 0.008). In‐hospital mortality within 1‐year post‐index date was higher in patients with lower weight (P = 0.002), body mass index (P = 0.009), SBP (P < 0.001), DBP (P < 0.001), sodium (P < 0.001), eGFR (P < 0.001) and higher heart rate (P = 0.039), urea (P < 0.001), serum potassium (P = 0.038), serum creatinine (P < 0.001), and uric acid (P < 0.001). In‐hospital mortality within 1‐year post‐index date was also higher in patients with severe or end‐stage chronic kidney disease (CKD) compared with mild/moderate CKD (P < 0.001) and in patients with HF with reduced ejection fraction (HFrEF) compared with those with mid‐range or preserved ejection fraction (P < 0.001). The most commonly prescribed HF medications at discharge were loop diuretics (89.2%), β‐blockers (68.5%), mineralocorticoid receptor antagonists (56.2%), angiotensin‐converting enzyme inhibitors (31.5%), and angiotensin receptor blockers (20.8%). Conclusions This study provides a greater understanding of the characteristics, treatment patterns, and outcome of hospitalized HF patients in a leading referral centre in Malaysia and will aid the implementation of meaningful interventions to improve patient outcome for HF patients.

Abstract
Objective: Current guidelines for gout recommend a treat-to-target approach with serum uric acid (SUA). However, there is little evidence for the dose-dependent effects of urate-lowering therapy (ULT). Herein, we analyzed the reported SUA-lowering effect and SUA target achievement differences for various doses of xanthine oxidase inhibitors. Methods: Approved ULT drugs were selected from the FDA Drug Database. We included prospective randomized controlled trials of ULT drugs from ClinicalTrials.gov, articles published in the journal “Drugs”, and Embase, a literature database. A meta-analysis was performed to determine the ability of different ULT drugs and doses to lower and maintain a target SUA < 6 mg/dL. Results: We identified 35 trials including 8172 patients with a baseline SUA of 8.92 mg/dL. The allopurinol, febuxostat, and topiroxostat showed dose-proportional SUA-lowering responses. Compared with allopurinol 300 mg daily, febuxostat 80 mg daily and 120 mg daily more effectively maintained SUA < 6 mg/dL. Conclusion: Allopurinol, febuxostat, and topiroxostat showed dose-proportional ability to lower and achieve a target SUA < 6 mg/dL. Significance and Innovations. We showed dose-dependent SUA lowering effects of allopurinol, febuxostat, and topiroxostat. Febuxostat is effective at ULT compared to allopurinol and could be potentially offered as an alternative agent when patients (1) have CKD, (2) have the human leukocyte antigen HLA-B*5801 allele, and (3) become refractory to allopurinol. Gradual allopurinol dose increase with a lower starting dose is needed in CKD.

Time-varying serum uric acid predicts new-onset atrial fibrillation in treated hypertensive patients. The LIFE Study. EXPLORATION OF MEDICINE 2022.

Abstract
Aim: The Losartan Intervention For Endpoint reduction in hypertension (LIFE) Study showed less new-onset atrial fibrillation (AF) in hypertensive patients receiving losartan- vs. atenolol-based treatment. Because losartan reduces serum uric acid (SUA) levels, the aim of the present study was to investigate relations of SUA with new-onset AF in the study.
Methods: Hypertensive patients with electrocardiographic (ECG) left ventricular hypertrophy (LVH) and no prior AF (n = 8,243) were treated for 5.0 ± 0.4 years with losartan- or atenolol-based therapy. Associations of SUA with new-onset AF documented by Minnesota coding were assessed by Cox models using SUA and systolic blood pressure as time-varying covariates to take into account changes of SUA related to losartan or diuretic treatment, changes in renal function, and aging.
Results: Time-varying SUA was associated with new AF defined by Minnesota code [hazard ratio (HR) = 1.19 per 16.8 μmol/L (1 mg/dL), (95% confidence intervals (CIs), 1.12–1.26), P < 0.0001], independent of losartan treatment [HR = 0.75 (95% CIs, 0.61–0.93), P = 0.007], older age [HR = 1.95 per 7.0 years (95% CIs, 1.73–2.20), P < 0.0001], male sex [HR = 1.46 (95% CIs, 1.09–1.94), P = 0.010] and higher Cornell voltage-duration product [HR = 1.10 per 1,023 ms·mm (95% CIs, 1.01–1.21), P = 0.034]. Similar results were obtained in Cox models with SUA levels partitioned according to baseline quartiles and in which AF was defined by physician reports or by both Minnesota coding and physician reports.
Conclusions: In-treatment SUA is a strong predictor for new-onset AF in hypertensive patients, independent of effects of antihypertensive treatment, age, sex, and ECG-LVH. Further research is needed to clarify how uric acid may provoke AF (ClinicalTrials.gov identifier: NCT00338260).

Topiroxostat versus allopurinol in patients with chronic heart failure complicated by hyperuricemia: A prospective, randomized, open-label, blinded-end-point clinical trial. PLoS One 2022; 17:e0261445. [PMID: 35077456 PMCID: PMC8789120 DOI: 10.1371/journal.pone.0261445] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Accepted: 11/08/2021] [Indexed: 11/23/2022] Open
Abstract
Background The benefits of xanthine oxidase inhibitors to chronic heart failure (CHF) patients is controversial. We investigated the beneficial effects of a novel xanthine oxidoreductase inhibitor, topiroxostat, in patients with CHF and hyperuricemia (HU), in comparison to allopurinol. Methods and results The prospective, randomized open-label, blinded-end-point study was performed in 141 patients with CHF and HU at 4 centers. Patients were randomly assigned to either topiroxostat or allopurinol group to achieve target uric acid level ≤6.0 mg/dL. According to the protocol, 140 patients were followed up for 24 weeks. Percent change in ln (N-terminal-proB-type natriuretic peptide) at week 24 (primary endpoint) was comparable between topiroxostat and allopurinol groups (1.6±8.2 versus -0.4±8.0%; P = 0.17). In the limited number of patients with heart failure with reduced ejection fraction (HFrEF) (left ventricle ejection fraction <45%), ratio of peak early diastolic flow velocity at mitral valve leaflet to early diastolic mitral annular motion velocity (E/e’) decreased in topiroxostat group, but not in allopurinol group. Urinary 8-hydroxy-2’-deoxyguanosine and L-type fatty acid-binding protein levels increased and osmolality decreased significantly in allopurinol group, while these changes were less or absent in topiroxostat group. In allopurinol group HFrEF patients, additional to the increases in these urinary marker levels, urinary creatinine levels decreased, with no change in clearance, but not in topiroxostat group. Conclusions Compared with allopurinol, topiroxostat did not show great benefits in patients with CHF and HU. However, topiroxostat might have potential advantages of reducing left ventricular end-diastolic pressure, not worsening oxidative stress in proximal renal tubule, and renoprotection over allopurinol in HFrEF patients.

Abstract
Objectives: A systematic review and meta-analysis was performed to evaluate the potential prognostic role of serum uric acid (SUA) in patients with chronic heart failure (CHF). Methods: The Embase, PubMed, Web of Science and Cochrane Library databases were searched up to 5 April 2021 for relevant publications. Random effects model was used to pool data. STATA15.0 software was used to perform meta-analysis. Heterogeneity was assessed using the Cochran Q statistic (significance level of P < 0.10) and I2 statistics (significance level of 50%). Results: Ultimately, 18 publications reporting adverse events in CHF patients were included. The results indicate reveal associations between a high level of SUA and the risk of all-cause mortality (HR 2.24, 95% CI 1.49–3.37), cardiovascular mortality (HR 1.14, 95% CI 1.06–1.23), and the composite of death or cardiac events (HR 1.26, 95% CI 1.01–1.56) in CHF patients. A 1 mg/dL increase in serum uric acid led to 4% (HR 1.04, 95% CI 1.02–1.05) and 9% (HR 1.09, 95% CI 1.03–1.17) increases in the risk of all-cause mortality and the composite endpoint of death or cardiac events in CHF patients, respectively. Conclusion: Serum uric acid is positively associated with the risk of adverse events in CHF patients.

Abstract
BACKGROUND: In the aviation world, hyperuricemia can endanger flight safety through the risk of incapacitation, either associated with gout disease or associated with an increased risk of cardiovascular disease. This study aims to determine the prevalence of hyperuricemia in civil pilots in Indonesia and the identification of risk factors for hyperuricemia in civil pilots in Indonesia.METHODS: The study used a cross-sectional method from the medical records of civil pilots at the Aviation Medical Center, Jakarta, who were examined on 1 November 2019 through 30 April 2020. Data collected from medical records included: laboratory data of uric acid, age, total flight hours, Body Mass Index (BMI), and alcohol consumption. Hyperuricemia is a plasma urate concentration > 420 µmol · L-1(7 mg · dl-1).RESULTS: The research sample amounted to 5202 pilots; 18.4% had hyperuricemia. Pilots who have total flight hours ≥5000 have a reduced risk of hyperuricemia by 24% compared to pilots with total flight hours <5000. Obese and overweight pilots had a 2.98 times and 1.36 times, respectively, greater risk of hyperuricemia than pilots who had a normal BMI. Based on BMI criteria classification of WHO Asia Pacific, obese is ≥25 and overweight is 23-24.9. Furthermore, compared to pilots who did not consume alcohol, pilots who consumed alcohol had a 14.68 times greater risk of developing hyperuricemia.CONCLUSION: The prevalence of hyperuricemia in civil pilots in Indonesia is 18.4%. Obesity, overweight, and alcohol consumption increase the risk of hyperuricemia in civil pilots in Indonesia.Tisera SC, Agustina A, Soemarko DS.

Abstract
Objective Heart failure (HF) is a common and highly morbid cardiovascular disorder. Oxidative stress worsens HF, and uric acid (UA) is a useful oxidative stress marker. The novel anti-hyperuricemic drug febuxostat is a potent non-purine selective xanthine oxidase inhibitor. The present study examined the UA-lowering and prognostic effects of febuxostat in patients with HF compared with conventional allopurinol. Methods This multicenter, randomized trial included 263 patients with chronic HF who were randomly assigned to two groups and received allopurinol or febuxostat (UA >7.0 mg/dL). All patients were followed up for 3 years after enrollment. Results There were no significant differences in baseline clinical characteristics between the two groups. The UA level was significantly decreased after 3 years of drug administration compared with the baseline in both groups. Urine levels of the oxidative stress marker 8-hydroxy-2′-deoxyguanosine were lower in the febuxostat group than in the allopurinol group (11.0 ± 9.6 vs. 22.9 ± 15.9 ng/mL), and the rate of patients free from hospitalization due to worsening HF tended to be higher in the febuxostat group than in the allopurinol group (89.0% vs. 83.0%). Conclusions Febuxostat is potentially more effective than allopurinol for treating patients with chronic HF and hyperuricemia. This study was registered in the University Hospital Medical Information Network Clinical Trials Registry (https://www.umin.ac.jp/ctr/; ID: 000009817).

Abstract
Inflammation has been recognized as a major pathophysiological contributor to the entire spectrum of human heart failure (HF), including HF with reduced ejection fraction, HF with preserved ejection fraction, acute HF and cardiogenic shock. Nevertheless, the results of several trials attempting anti-inflammatory strategies in HF patients have not been consistent or motivating and the clinical implementation of anti-inflammatory treatments for HF still requires larger and longer trials, as well as novel and/or more specific drugs. The present work reviews the different inflammatory mechanisms contributing to each type of HF, the major inflammatory mediators involved, namely tumor necrosis factor alpha, the interleukins 1, 6, 8, 10, 18, and 33, C-reactive protein and the enzymes myeloperoxidase and inducible nitric oxide synthase, and their effects on heart function. Furthermore, several trials targeting these mediators or involving other anti-inflammatory treatments in human HF are also described and analyzed. Future therapeutic advances will likely involve tailored anti-inflammatory treatments according to the patient's inflammatory profile, as well as the development of resolution pharmacology aimed at stimulating resolution of inflammation pathways in HF.

Abstract
OBJECTIVE To detect the prevalence of hyperuricemia in Egyptian rheumatoid arthritis (RA) patients as well as to assess its association with the severity of joint inflammation and disease-modifying antirheumatic drugs (DMARDs) in those patients. METHODS A total of 150 RA patients were recruited; all patients were subjected to (1) clinical and functional assessment by disease activity score in 28 joints (DAS28) and modified health assessment questionnaire (MHAQ). (2) Laboratory investigations: serum uric acid (SUA) level, complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP), tumor necrosis factor α (TNF-α), interleukin 1 (IL1), and interleukin 6 (IL6) levels. (3) Radiological evaluation: (A) plain X-ray of both hands and feet; (B) musculoskeletal ultrasound (MSUS) of both wrists, hands, shoulder, ankle, and knee joints. RESULTS SUA was significantly correlated with disease activity by DAS28. Acute-phase reactants and inflammatory markers (IL1β, IL6, and TNF-α) were also significantly elevated in RA patients with low and high hyperuricemia compared to those with normal SUA. A total of 90% of RA patients with low hyperuricemia had synovial proliferation with power Doppler (1+ and 2+), and 30 patients had mild effusion (1+), while nearly all patients with high hyperuricemia had hypoechoic synovial proliferation (2+ and 3+), and 20 patients had moderate effusion. However, 70% RA patients with normal serum uric acid showed mild synovitis and effusion (1+). No significant association was found between the administered DMARDs and levels of SUA as well as inflammatory markers; however, high-dose steroid treatment was associated with high SUA level. CONCLUSION Elevation of serum uric acid levels in Egyptian RA patients was prevalent and might be an inflammatory marker for severity of joint inflammation. Moreover, higher doses of steroids could be considered a cause of hyperuricemia.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive life-threatening disease of the pulmonary vasculature. Despite the introduction of targeted therapies, prognosis remains poor. In pediatric PAH, reliable prognostic biomarkers are needed to inform clinicians on disease progression and risk of mortality, in order to be able to assess the need for escalation of medical therapy, consider surgical options such as Pott's shunt and listing for (heart)-lung transplantation. This review provides an overview of prognostic biomarkers that are considered to carry potential for the clinical management of pediatric PAH. These include conventional physiological biomarkers [resting heart rate, heart rate variability (HRV), a child's growth], biomarkers of functional status [World Health Organization functional class, 6-minute walk distance (6MWD), parameters derived from cardiopulmonary exercise testing (CPET), daily physical activity level], electrocardiographic biomarkers, circulating serum biomarkers (natriuretic peptides, uric acid, neurohormones, inflammatory markers, and novel circulating biomarkers), and multiple hemodynamic biomarkers and imaging biomarkers [echocardiography and cardiac magnetic resonance (CMR)]. In recent years, many potential prognostic biomarkers have become available for the management of PAH in children. As the available prognostic biomarkers reflect different aspects of the disease process and functional implications, a multi-marker approach appears the most useful for guiding therapy decisions and improve outcome in pediatric PAH.

Abstract
Aim. To evaluate the prognostic impact of serum uric acid (SUA) on clinical outcomes in patients with acute decompensated heart failure, as well as identify the correlation between hyperuricemia and renal function and diuretic resistance in these patients.
Materials and methods. The study included 175 patients (125 men and 50 women) with NYHA class IIIV acute decompensated heart failure. Median age was 64 (5675) years. The Information regarding the survival was obtained 3 years after the admission by telephone calls.
Results. 57 patients reached the end point (death from all causes); therefore, all patients were divided into groups: "alive", "dead". The SUA levels did not differ in the groups. The only significant difference in the studied parameters was the estimated glomerular filtration rate (eGFR), which was significantly higher in the "alive" group [70.5 (52.894) and 56 (4079), respectively; p=0.006]. A moderate negative correlation was found between SUA levels and eGFR in the correlation analysis (r=-0.313, p0.001). A comparative analysis showed, that SUA level on admission was significantly higher in patients who subsequently received increased doses of diuretics than in patients with a satisfactory response to standard doses of diuretics [567.8 (479.6791.9) and 512 (422.4619.4), respectively; p=0.011]. Also, higher eGFR level on admission was observed in patients from the normal SUA level group than in patients from the hyperuricemia group [94 (74.5101.5) and 63 (48.881.3), respectively; p=0.002].
Conclusion. We found no significant differences in the uric acid level in patients who reached the end point and those who did not reach it during the three-year follow-up. However, the found correlation between uric acid levels and diuretic resistance calls for further research.

Abstract
High uric acid (HUA) is associated with insulin resistance (IR) in cardiomyocytes. We investigated whether metformin protects against HUA-induced IR in cardiomyocytes. We exposed primary cardiomyocytes to HUA, and cellular glucose uptake was quantified by measuring the uptake of 2-NBDG, a fluorescent glucose analog. Western blot was used to examine the levels of signalling protein. Membrane of glucose transporter type 4 (GLUT4) was analysed by immunofluorescence. We monitored the impact of metformin on HUA-induced IR and in myocardial tissue of an acute hyperuricaemia mouse model established by potassium oxonate treatment. Treatment with metformin protected against HUA-reduced glucose uptake induced by insulin in cardiomyocytes. HUA directly inhibited the phosphorylation of Akt and the translocation of GLUT4 induced by insulin, which was blocked by metformin. Metformin promoted phosphorylation of AMP-activated protein kinase (AMPK) and restored the insulin-stimulated glucose uptake in HUA-induced IR cardiomyocytes. As a result of these effects, in a mouse model of acute hyperuricaemia, metformin improved insulin tolerance and glucose tolerance, accompanied by increased AMPK phosphorylation, Akt phosphorylation and translocation of GLUT4 in myocardial tissues. As expected, AICAR, another AMPK activator, had similar effects to metformin, demonstrating the important role of AMPK activation in protecting against IR induced by HUA in cardiomyocytes. Metformin protects against IR induced by HUA in cardiomyocytes and improves insulin tolerance and glucose tolerance in an acute hyperuricaemic mouse model, along with the activation of AMPK. Consequently, metformin may be an important potential new treatment strategy for hyperuricaemia-related cardiovascular disease.

Serum uric acid and outcomes in patients with chronic heart failure through the whole spectrum of ejection fraction phenotypes: Analysis of the ESC-EORP Heart Failure Long-Term (HF LT) Registry. Eur J Intern Med 2021; 89:65-75.

Abstract
BACKGROUND Retrospective analyses of clinical trials indicate that elevated serum uric acid (sUA) predicts poor outcome in heart failure (HF). Uric acid can contribute to inflammation and microvascular dysfunction, which may differently affect different left ventricular ejection fraction (LVEF) phenotypes. However, role of sUA across LVEF phenotypes is unknown. OBJECTIVES We investigated sUA association with outcome in a prospective cohort of HF patients stratified according to LVEF. METHODS Through the Heart Failure Long-Term Registry of the European Society of Cardiology (ESC-EORP-HF-LT), 4,438 outpatients were identified and classified into: reduced (<40% HFrEF), mid-range (40-49% HFmrEF), and preserved (≥50% HFpEF) LVEF. Endpoints were the composite of cardiovascular death/HF hospitalization, and individual components. RESULTS Median sUA was 6.72 (IQ:5.48-8.20) mg/dl in HFrEF, 6.41 (5.02-7.77) in HFmrEF, and 6.30 (5.20-7.70) in HFpEF. At a median 372-day follow-up, the composite endpoint occurred in 648 (13.1%) patients, with 176 (3.6%) deaths and 538 (10.9%) HF hospitalizations. Compared with lowest sUA quartile (Q), Q-III and Q-IV were significantly associated with the composite endpoint (adjusted HR 1.68: 95% CI 1.11-2.54; 2.46: 95% CI 1.66-3.64, respectively). By univariable analyses, HFrEF and HFmrEF patients in Q-III and Q-IV, and HFpEF patients in Q-IV, showed increased risk for the composite endpoint (P<0.05 for all); after model-adjustment, significant association of sUA with outcome persisted among HFrEF in Q-IV, and HFpEF in Q-III-IV. CONCLUSIONS In a large, contemporary-treated cohort of HF outpatients, sUA is an independent prognosticator of adverse outcome, which can be appreciated in HErEF and HFpEF patients.

Abstract
BACKGROUND The role of cardiac index (CI) and right atrial pressure (RAP) for predicting long-term outcomes of heart failure has not been well established. The aim of this study was to investigate long-term cardiac outcomes in patients with heart failure having various combinations of CI and RAP. METHODS A total of 787 heart failure patients who underwent right-heart catheterization were retrospectively categorized into the following four groups: Preserved CI (≥2.5 L/min/m2) and Low RAP (<8 mmHg) (PRE-CI/L-RAP; n = 285); Preserved CI (≥2.5 L/min/m2) and High RAP (≥8 mmHg) (PRE-CI/H-RAP; n = 242); Reduced CI (<2.5 L/min/m2) and Low RAP (<8 mmHg) (RED-CI/L-RAP; n = 123); and Reduced CI (<2.5 L/min/m2) and High RAP (≥8 mmHg) (RED-CI/H-RAP; n = 137). Survival analysis was applied to investigate which groups were associated with major adverse cardiovascular events (MACE). RESULTS The RED-CI/L-RAP and RED-CI/H-RAP groups were significantly associated with MACE as compared with the PRE-CI/L-RAP and PRE-CI/H-RAP groups after adjustment for confounding factors (RED-CI/L-RAP vs. PRE-CI/L-RAP: HR 2.11 [95% CI 1.33-3.37], p = 0.002; RED-CI/H-RAP vs. PRE-CI/L-RAP: HR 2.18 [95% CI 1.37-3.49], p = 0.001; RED-CI/L-RAP vs. PRE-CI/H-RAP: HR 1.86 [95% CI 1.16-3.00], p = 0.01; RED-CI/H-RAP vs. PRE-CI/H-RAP: HR 1.92 [95% CI 1.26-2.92], p = 0.002), whereas the difference between the RED-CI/H-RAP and RED-CI/L-RAP groups was not significant (HR 1.03 [95% CI 0.64-1.66], p = 0.89). CONCLUSIONS The hemodynamic severity categorized by CI and RAP levels provided clear risk stratification in patients with symptomatic heart failure. Low CI was an independent predictor of long-term cardiac outcomes.

Serum Sulfhydryl Groups, Malondialdehyde, Uric Acid, and Bilirubin as Predictors of Adverse Outcome in Heart Failure Patients due to Ischemic or Nonischemic Cardiomyopathy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6693405. [PMID: 33936385 PMCID: PMC8062185 DOI: 10.1155/2021/6693405] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 03/24/2021] [Accepted: 04/01/2021] [Indexed: 11/17/2022]
Abstract
Oxidative stress plays a significant role in the pathogenesis of heart failure (HF). The aim of the study was to investigate the prognostic value of oxidation-reduction (redox) markers in patients with HF due to ischemic and nonischemic cardiomyopathy. The study included 707 patients of HF allocated into two groups depending on ethology: ischemic cardiomyopathy (ICM) (n = 435) and nonischemic cardiomyopathy (nICM) (n = 272), who were followed up for one year. The endpoint occurrence (mortality or heart transplantation) in a 1-year follow-up was similar in the ICM and nICM group. The predictive value of endpoint occurrence of oxidative stress biomarkers such as the serum protein sulfhydryl groups (PSH), malondialdehyde (MDA), uric acid (UA), bilirubin, and MDA/PSH ratio and other clinical and laboratory data were assessed in both groups (ICM and nICM) separately using univariate and multivariate Cox regression analyses. In multivariate analysis, the higher concentrations of UA (p = 0.015, HR = 1.024, 95% CI (1.005-1.044)) and MDA (p = 0.004, HR = 2.202, 95% CI (1.296-3.741)) were significantly associated with adverse prognosis in patients with ICM. Contrastingly, in patients with nICM, we observed that higher bilirubin concentration (p = 0.026, HR = 1.034, 95% CI (1.004-1.064)) and MDA/PSH ratio (p = 0.034, HR = 3.360, 95% CI (1.096-10.302)) were significantly associated with increased risk of death or HT. The results showed the association of different oxidative biomarkers on the unfavorable course of heart failure depending on etiology.

Abstract
Background:
This prospective observational study examined whether hyperuricemia may be associated with impaired left ventricular (LV) systolic function and increased cardiac load resulting from increased arterial stiffness. Methods and Results:
In 1,880 middle-aged (mean [±SD] age 45±9 years) healthy men, serum uric acid (UA) levels, pre-ejection period/ejection time (PEP/ET) ratio, serum N-terminal pro B-type natriuretic peptide (NT-proBNP) levels, and brachial-ankle pulse wave velocity (baPWV) were measured at the start and end of the 3-year study period. Linear regression analysis revealed that serum UA levels measured at baseline were significantly associated with the PEP/ET ratio, but not with serum NT-proBNP levels, measured at baseline (β=0.73×10−1, P<0.01) and at the end of the study period (β=0.68×10−1, P<0.01). The change in the PEP/ET ratio during the study period was significantly greater in the High-UA (UA >7 mg/dL in 2009 and 2012) than Low-UA (UA ≤7 mg/dL in 2009 and 2012) group. Mediation analysis demonstrated both direct and indirect (via increases in baPWV) associations between serum UA measured at baseline and the PEP/ET ratio measured at the end of the study period. Conclusions:
In healthy middle-aged Japanese men, hyperuricemia may be associated with an accelerated decline in ventricular systolic function, both directly and indirectly, via increases in arterial stiffness.

Abstract
Background: Subarachnoid hemorrhage (SAH) is a devastating disease with high morbidity and mortality. Hypoxia-induced changes and hemoglobin accumulation within the subarachnoid space are thought to lead to oxidative stress, early brain injury, and delayed vasospasm. This study aimed to evaluate the antioxidant status and its impact on neurological outcome in patients with aneurysmal SAH. Methods: In this prospective observational study, 29 patients with aneurysmal SAH were included (mean age 54.7 ± 12.4). Blood and cerebrospinal fluid (CSF) samples were collected on days (d) 1, 3, and 7. In addition, 29 patients without intracranial hemorrhage served as controls. The antioxidant system was analyzed by glutathione peroxidase (GSH-Px; U/L) and total and free glutathione-sulfhydryl (GSH; mg/L) in the plasma. Superoxide dismutase (SOD, U/mL) and total antioxidant capacity (TAC, µmol/L) were measured in the serum and CSF. Clinical data were compiled on admission (Hunt and Hess grade, Fisher grade, and GCS). Neurological and cognitive outcome (modified Rankin scale (mRS), Glasgow Outcome Scale Extended (GOSE) and Montreal Cognitive Assessment (MoCA)) was assessed after 6 weeks (6 w) and 6 months (6 m). Results: Plasma levels of SOD increased from day 1 to 7 after SAH (d1: 1.22 ± 0.36 U/L; d3: 1.25 ± 0.33 U/L, p = 0.99; d7: 1.52 ± 0.4 U/L, p = 0.019) and were significantly higher compared to controls (1.11 ± 0.27 U/L) at day 7 (p < 0.001). Concordantly, CSF levels of SOD increased from day 1 to 7 after SAH (d1: 1.22 ± 0.41 U/L; d3: 1.77 ± 0.73 U/L, p = 0.10; d7: 2.37 ± 1.29 U/L, p < 0.0001) without becoming significantly different compared to controls (1.74 ± 0.8 U/L, p = 0.09). Mean plasma TAC at day 1 (d1: 77.87 ± 49.72 µmol/L) was not statistically different compared to controls (46.74 ± 32.42 µmol/L, p = 0.25). TAC remained unchanged from day 1 to 7 (d3: 92.64 ± 68.58 µmol/L, p = 0.86; d7: 74.07 ± 54.95 µmol/L, p = 0.8) in plasma. TAC in CSF steeply declined from day 1 to 7 in patients with SAH becoming significantly different from controls at days 3 and 7 (d3: 177.3 ± 108.7 µmol/L, p = 0.0046; d7: 85.35 ± 103.9 µmol/L, p < 0.0001). Decreased SOD levels in plasma and CSF are associated with a worse neurological outcome 6 weeks (mRS: CSF p = 0.0001; plasma p = 0.027/GOSE: CSF p = 0.001; plasma p = 0.001) and 6 months (mRS: CSF p = 0.001; plasma p = 0.09/GOSE: CSF p = 0.001; plasma p = 0.001) after SAH. Increased plasma TAC correlated with a worse neurological outcome 6 weeks (mRS: p = 0.001/GOSE p = 0.001) and 6 months (mRS p = 0.001/GOSE p = 0.001) after SAH. Conclusion: In our study, a reduction in the antioxidative enzyme SOD and elevated TAC were associated with a poorer neurological outcome reflected by mRS and GOSE at 6 weeks and 6 months after SAH. A lower initial SOD CSF concentration was associated with the late deterioration of cognitive ability. These findings support the mounting evidence of the role of oxidative stress in early brain injury formation and unfavorable outcome after SAH.

Dynamic changes in cardiovascular and systemic parameters prior to sudden cardiac death in heart failure with reduced ejection fraction: a PARADIGM-HF analysis. Eur J Heart Fail 2021; 23:1346-1356. [PMID: 33565237 DOI: 10.1002/ejhf.2120] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 01/02/2021] [Accepted: 02/02/2021] [Indexed: 12/16/2022] Open
Abstract
AIMS Prognostic models of sudden cardiac death (SCD) typically incorporate data at only a single time-point. We investigated independent predictors of SCD addressing the impact of integrating time-varying covariates to improve prediction assessment. METHODS AND RESULTS We studied 8399 patients enrolled in the PARADIGM-HF trial and identified independent predictors of SCD (n = 561, 36% of total deaths) using time-updated multivariable-adjusted Cox models, classification and regression tree (CART), and logistic regression analysis. Compared with patients who were alive or died from non-sudden cardiovascular deaths, patients who suffered a SCD displayed a distinct temporal profile of New York Heart Association (NYHA) class, heart rate and levels of three biomarkers (albumin, uric acid and total bilirubin), with significant differences observed more than 1 year prior to the event (Pinteraction < 0.001). In multivariable models adjusted for baseline covariates, seven time-updated variables independently contributed to SCD risk (incremental likelihood chi-square = 46.2). CART analysis identified that baseline variables (implantable cardioverter-defibrillator use and N-terminal prohormone of B-type natriuretic peptide levels) and time-updated covariates (NYHA class, total bilirubin, and total cholesterol) improved risk stratification. CART-defined subgroup of highest risk had nearly an eightfold increment in SCD hazard (hazard ratio 7.7, 95% confidence interval 3.6-16.5; P < 0.001). Finally, changes over time in heart rate, NYHA class, blood urea nitrogen and albumin levels were associated with differential risk of sudden vs. non-sudden cardiovascular deaths (P < 0.05). CONCLUSIONS Beyond single time-point assessments, distinct changes in multiple cardiac-specific and systemic variables improved SCD risk prediction and were helpful in differentiating mode of death in chronic heart failure.

Combined pre- and post-capillary pulmonary hypertension: The clinical implications for patients with heart failure. PLoS One 2021; 16:e0247987. [PMID: 33651852 PMCID: PMC7924774 DOI: 10.1371/journal.pone.0247987] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 02/17/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The prognostic implications of combined pre- and post-capillary pulmonary hypertension (Cpc-PH) in patients with pulmonary hypertension due to left heart disease (PH-LHD) remain controversial. The aim of this retrospective study was to evaluate the new PH-LHD criteria, recommended by the 6th World Symposium on Pulmonary Hypertension and to determine the prognostic value of Cpc-PH. METHODS A total of 701 patients with symptomatic heart failure who had undergone right-heart catheterization were divided into the following four groups: (i) Isolated post-capillary PH (Ipc-PH) group; mean pulmonary artery pressure (mPAP) >20 mmHg, pulmonary artery wedge pressure (PAWP) >15 mmHg, and pulmonary vascular resistance (PVR) <3 Wood units (WU) (ii) Cpc-PH group; mPAP >20 mmHg, PAWP >15 mmHg, and PVR ≥3 WU (iii) borderline-PH group; mPAP >20 mmHg and PAWP ≤15 mmHg (iv) non-PH group; mPAP ≤20 mmHg. Multivariate Cox hazard analysis was used to investigate whether Cpc-PH was associated with cardiac outcomes. RESULTS The study subjects were allocated into the Ipc-PH (n = 268), Cpc-PH (n = 54), borderline-PH (n = 112), or non-PH (n = 267) groups. The Cpc-PH group was associated significantly with adverse cardiac events even after adjustment for clinically relevant confounding factors for heart failure prognosis (vs. non-PH group: HR 2.98 [95% CI 1.81-4.90], P <0.001; vs. Ipc-PH group: HR: 1.92 [95% CI 1.19-3.08], P = 0.007). CONCLUSIONS The new definitions of PH-LHD stratified patients into 4 categories. Long-term clinical outcomes were significantly different between the four categories, with Cpc-PH having the worst cardiac outcomes.

Abstract
ZusammenfassungZahlreiche Untersuchungen zeigen, dass Patienten mit Hyperurikämie und insbesondere mit symptomatischer Hyperurikämie, einer Gicht, kardiovaskuläre Risikopatienten sind. Bei symptomatischer Hyperurikämie sollte nach aktuellen Leitlinien eine harnsäuresenkende Therapie mit Zielwert-Erreichung eingeleitet werden. Darüber hinaus sind die Diagnose und optimale Therapie der klassischen kardiovaskulären Risikofaktoren von besonderer Bedeutung.

Cardiovascular events in hyperuricemia population and a cardiovascular benefit-risk assessment of urate-lowering therapies: a systematic review and meta-analysis. Chin Med J (Engl) 2021; 133:982-993. [PMID: 32106120 PMCID: PMC7176444 DOI: 10.1097/cm9.0000000000000682] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Hyperuricemia and gout have become public health concerns; many important guidelines have recommended xanthine oxidase inhibitors (XOIs) as the first-line urate-lowering therapies (ULTs) to treat chronic gout with hyperuricemia. However, whether treating hyperuricemia and gout with ULTs modifies cardiovascular risks remains controversial. The aim of this study was to assess the incident risk of cardiovascular (CV) events (CVE) in hyperuricemia population, assess the cardiovascular benefit-risk of ULTs in hyperuricemia patients with or without gout in diverse cardiovascular risk sub-groups, and specify the safety of different ULTs. METHODS We searched PubMed, Embase, the Cochrane Library, Wanfang, Chongqing VIP (CQVIP, en.cqvip.com), and China National Knowledge Infrastructure Database for prospective cohort studies and randomized controlled trials (RCTs) in English and Chinese. Potential medications included XOIs, and uricosurics. RCTs were divided into sub-groups analysis based on blinding status and patients' history of CV diseases. Risk ratios (RRs) were calculated and were reported with corresponding 95% confidence intervals (CIs) by fixed-effects or random-effects model. RESULTS Seven prospective cohort studies and 17 RCT studies were included. The risks of both major adverse cardiovascular events (MACE) (RR = 1.72, 95% CI 1.28-2.33) and CVE (RR = 1.35, 95% CI 1.12-1.62) were higher in the hyperuricemia population than non-hyperuricemia one. In seven RCT studies where XOIs were compared with no-treatment or placebo, the results of five low CV risk studies showed that XOIs lowered the risks of both MACE (RR = 0.35, 95% CI 0.20-0.62) and CVE (RR = 0.61, 95% CI 0.44-0.85); whereas two high CV risk studies showed that XOIs lowered the risk of CVE (RR = 0.69, 95% CI 0.54-0.88) rather than MACE (RR = 0.62, 95% CI 0.29-1.35). In nine RCT studies where the cardiovascular safety between febuxostat and allopurinol were compared, no statistical difference was found in the risk of MACE or CVE. CONCLUSIONS The hyperuricemia population does have a higher incidence of CVE, and the results suggested that XOIs might reduce the incidence of MACE and total CVE. In addition, from the perspective of cardiovascular safety, febuxostat equaled allopurinol in our meta-analysis.

Impact of hospital volume on clinical outcomes of hospitalized heart failure patients: analysis of a nationwide database including 447,818 patients with heart failure. BMC Cardiovasc Disord 2021; 21:49. [PMID: 33494701 PMCID: PMC7836495 DOI: 10.1186/s12872-021-01863-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Accepted: 01/11/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hospital volume is known to be associated with outcomes of patients requiring complicated medical care. However, the relationship between hospital volume and prognosis of hospitalized patients with heart failure (HF) remains not fully understood. We aimed to clarify the impact of hospital volume on clinical outcomes of hospitalized HF patients using a nationwide inpatient database. METHODS AND RESULTS We studied 447,818 hospitalized HF patients who were admitted from January 2010 and discharged until March 2018 included in the Japanese Diagnosis Procedure Combination database. According to the number of patients, patients were categorized into three groups; those treated in low-, medium-, and high-volume centers. The median age was 81 years and 238,192 patients (53%) were men. Patients who had New York Heart Association class IV symptom and requiring inotropic agent within two days were more common in high volume centers than in low volume centers. Respiratory support, hemodialysis, and intra-aortic balloon pumping were more frequently performed in high volume centers. As a result, length of hospital stay was shorter, and in-hospital mortality was lower in high volume centers. Lower in-hospital mortality was associated with higher hospital volume. Multivariable logistic regression analysis fitted with generalized estimating equation indicated that medium-volume group (Odds ratio 0.91, p = 0.035) and high-volume group (Odds ratio 0.86, p = 0.004) had lower in-hospital mortality compared to the low-volume group. Subgroup analysis showed that this association between hospital volume and in-hospital mortality among overall population was seen in all subgroups according to age, presence of chronic renal failure, and New York Heart Association class. CONCLUSION Hospital volume was independently associated with ameliorated clinical outcomes of hospitalized patients with HF.
