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.

In chronic heart failure (HF), some parameters of oxidative stress are correlated with disease severity. The aim of this study was to evaluate the importance of oxidative stress biomarkers in prognostic risk stratification (death and combined endpoint: heart transplantation or death). In 774 patients, aged 48-59 years, with chronic HF with reduced ejection fraction (median: 24.0 (20-29)%), parameters such as total antioxidant capacity, total oxidant status, oxidative stress index, and concentration of uric acid (UA), bilirubin, protein sulfhydryl groups (PSH), and malondialdehyde (MDA) were measured. The parameters were assessed as predictive biomarkers of mortality and combined endpoint in a 1-year follow-up. The multivariate Cox regression analysis was adjusted for other important clinical and laboratory prognostic markers. Among all the oxidative stress markers examined in multivariate analysis, only MDA and UA were found to be independent predictors of death and combined endpoint. Higher serum MDA concentration increased the risk of death by 103.0% (HR=2.103; 95% CI (1.330-3.325)) and of combined endpoint occurrence by 100% (HR=2.000; 95% CI (1.366-2.928)) per μmol/L. Baseline levels of MDA in the 4th quartile were associated with an increased risk of death with a relative risk (RR) of 3.64 (95% CI (1.917 to 6.926), p<0.001) and RR of 2.71 (95% CI (1.551 to 4.739), p<0.001) for the occurrence of combined endpoint as compared to levels of MDA in the 1st quartile. Higher serum UA concentration increased the risk of death by 2.1% (HR=1.021; 95% CI (1.005-1.038), p<0.001) and increased combined endpoint occurrence by 1.4% (HR=1.014; 95% CI (1.005-1.028), p<0.001), for every 10 μmol/L. Baseline levels of UA in the 4th quartile were associated with an increased risk for death with a RR of 3.21 (95% CI (1.734 to 5.931)) and RR of 2.73 (95% CI (1.560 to 4.766)) for the occurrence of combined endpoint as compared to the levels of UA in the 1st quartile. In patients with chronic HF, increased MDA and UA concentrations were independently related to poor prognosis in a 1-year follow-up.

Abstract Background and Aims The cardiorenal syndrome was studied in heart failure (HF) patients with respect to the “Shrunken pore syndrome” (SPS) that is characterized by a difference in renal filtration between cystatin C and creatinine, resulting in a low eGFRcystatin C/eGFRcreatinine-ratio. Method 373 patients hospitalized for HF were retrieved from the HeARt and brain failure inVESTigation trial (HARVEST-Malmö). We used CKD-EPI formulas for estimated glomerular filtration rate (eGFR). Presence of SPS was defined as eGFRcystatinC ≤60% of eGFRcreatinine. In Cox regression multivariate models, associations between SPS, risk of death and risk of 30-day re-hospitalization were studied. Associations between SPS and impaired quality of life (QoL) were studied using multivariate logistic regressions. Results SPS was associated with all-cause mortality (124 events; hazard ratio (HR) 2.35; confidence interval (CI95%) 1.17-4.71; p=0.016 and with 30-day re-hospitalization (70 events; HR 1.82; CI95% 1.04-3.18; p=0.036). Analyses of QoL, based on a Kansas City Cardiomyopathy Questionnaire overall score &lt;50, revealed that SPS was associated with increased risk of low health-related QoL (odds ratios (OR) 2.15 (CI95% 1.03-4.49; p=0.042). Conclusion The results of this observational study show for the first time an association between SPS and poor prognosis in HF. Further studies are needed to confirm the results in HF cohorts and experimental settings to identify pathophysiological mechanisms.

Objectives: Several studies have investigated the association between serum uric acid (SUA) and the risks of coronary artery disease (CAD) but have yielded inconsistent results. The aim of this study was to assess whether there is an independent association of SUA with all-cause and cardiovascular disease (CVD) mortality in Chinese patients with CAD. Methods: A prospective cohort study of 1,799 patients was conducted. Cox regression models were used to estimate the association of SUA with the risk of death. Results: During a median follow-up of 3.9 years, 177 deaths were recorded and 126 of these were due to CVD. Patients in the highest SUA quartile had a 2.43-fold risk of all-cause mortality and a 2.44-fold risk of CVD mortality compared with those in the lowest quartile. In the subpopulation analysis, the association between SUA and mortality remained similar when participants were stratified by age, gender, body mass index and type of CAD. In contrast, we found a significant interaction with estimated glomerular filtration rate (eGFR). There was a stronger association between SUA and the risk of all-cause and CVD mortality among patients with an eGFR ≥60 ml/min/1.73 m2, but no significant association was found in the population with an eGFR <60 ml/min/1.73 m2. Conclusions: Elevated SUA levels were positively associated with an increased risk of all-cause and CVD mortality among CAD patients.

Background and Aims Chagas disease is a common cause of heart failure (HF) and death in developing countries. Although stroke is known to occur in these patients, an accurate estimate of stroke incidence is lacking. We aimed to determine the incidence of stroke and death in patients with HF, comparing Chagas and non-Chagas etiologies. Methods Cohort of stroke-free patients with HF (Framingham criteria) followed in a university-based outpatient clinic in Brazil. Baseline characteristics included sociodemographic, risk factor assessment, echocardiographic and electrocardiographic findings. Chagas disease was defined by appropriate serologic tests. Cause-specific Cox regression was used to search for predictors of stroke or death as separate outcomes. Results We studied 565 patients with HF between January 2003 and December 2018, mean age 54.3 ± 12.9 years, 305 (54.0%) females, 271/535 (50.7%) with Chagas disease. Chagas patients were older (55.5 vs. 53.1 years), more frequently women (60.5% vs. 47.3%), less frequently harbored coronary artery disease (14.5% vs. 34.1%) when compared to non-Chagas patients. Echocardiography showed more severe disease among non-Chagas patients [median left ventricle ejection fraction (LVEF) 37.3% vs. 47.0%]. Over a mean 42.9 (±34.4) months, we followed 404 (71.5%) patients, completing 1442 patient-years of follow-up. Stroke incidence was higher in Chagas when compared to non-Chagas patients (20.2 vs. 13.9 events per 1000 patient-years), while death rate was similar (41.6 vs. 43.1 deaths per 1000 patient-years). In the multivariable analysis for stroke outcome adjusted for LVEF and arrhythmias, cause-specific hazard ratio (CSHR) for Chagas was 2.54 (95% confidence interval 1.01–6.42, p = 0.048). Chagas disease was also associated with increased risk of death (CSHR 1.83; 95% confidence interval 1.04–3.24, p = 0.037). Conclusion Chagas disease is associated with increased risk of stroke and death when compared to other etiologies of HF, independently of HF severity or cardiac arrhythmias, suggesting other factors contribute to increased stroke risk and mortality in Chagas disease. Early prevention and treatment of Chagas disease is imperative to reduce a later risk of stroke in endemic areas.

Oxidative stress may be defined as an imbalance between reactive oxygen species (ROS) and the antioxidant system to counteract or detoxify these potentially damaging molecules. This phenomenon is a common feature of many human disorders, such as cardiovascular disease. Many of the risk factors, including smoking, hypertension, hypercholesterolemia, diabetes, and obesity, are associated with an increased risk of developing cardiovascular disease, involving an elevated oxidative stress burden (either due to enhanced ROS production or decreased antioxidant protection). There are many therapeutic options to treat oxidative stress-associated cardiovascular diseases. Numerous studies have focused on the utility of antioxidant supplementation. However, whether antioxidant supplementation has any preventive and/or therapeutic value in cardiovascular pathology is still a matter of debate. In this review, we provide a detailed description of oxidative stress biomarkers in several cardiovascular risk factors. We also discuss the clinical implications of the supplementation with several classes of antioxidants, and their potential role for protecting against cardiovascular risk factors.

Purpose: We aimed to study the influence of fast-track care programs in total hip and total knee replacements (THR and TKR) at Swedish hospitals on the risk of revision and mortality within 2 years after the operation. Methods: Data were collected from the Swedish Hip and Knee Arthroplasty Registers (SHAR and SKAR), including 67,913 THR and 59,268 TKR operations from 2011 to 2015 on patients with osteoarthritis. Operations from 2011 to 2015 Revision and mortality in the fast-track group were compared with non-fast-track using Kaplan–Meier survival analysis and Cox regression analysis with adjustments. Results: The hazard ratio (HR) for revision within 2 years after THR with fast-track was 1.19 (CI: 1.03–1.39), indicating increased risk, whereas no increased risk was found in TKR (HR 0.91; CI: 0.79–1.06). The risk of death within 2 years was estimated with a HR of 0.85 (CI: 0.74–0.97) for TKR and 0.96 (CI: 0.85–1.09) for THR in fast-track hospitals compared to non-fast-track. Conclusions: Fast-track programs at Swedish hospitals were associated with an increased risk of revision in THR but not in TKR, while we found the mortality to be lower (TKR) or similar (THR) as compared to non-fast track.

Abstract Background Serum uric acid (SUA) is a biomarker of several pathobiologies relevant to the pathogenesis of heart failure with preserved ejection fraction (HFpEF), though by itself may also worsen outcomes. In HF with reduced EF, SUA is independently associated with adverse outcomes and sacubitril/valsartan reduces SUA compared to enalapril. These effects in HFpEF have not been delineated. Purpose To determine the prognostic value of SUA, relationship of change in SUA to quality of life and outcomes, and influence of sacubitril/valsartan on SUA in HFpEF. Methods We analyzed 4,795 participants from the Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction (PARAGON-HF) trial. We related baseline hyperuricemia to the primary outcome (CV death and total HF hospitalization), its components, myocardial infarction or stroke, and a renal composite outcome. At the 4-month visit, the relationship between SUA change and Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OSS) and several biomarkers including N-terminal pro-B-type natriuretic peptide (NT-proBNP) were also assessed. We simultaneously adjusted for baseline and time-updated SUA to determine whether lowering SUA was associated with clinical benefit. Results Average age was 73±8 years and 52% were women. After multivariable adjustment, hyperuricemia was associated with increased risk for most outcomes (primary outcome HR 1.61, 95% CI 1.37, 1.90, Fig 1A). The treatment effect of sacubitril/valsartan for the primary outcome was not modified by baseline SUA (interaction p=0.11). Sacubitril/valsartan reduced SUA −0.38 mg/dL (95% CI: −0.45, −0.31) compared with valsartan (Fig 1B), with greater effect in those with baseline hyperuricemia (−0.50 mg/dL) (interaction p=0.013). Change in SUA was independently and inversely associated with change in KCCQ-OSS (p=0.019) and eGFR (p&lt;0.001), but not NT-proBNP (p=0.52). Time-updated SUA was a stronger predictor of adverse outcomes over baseline SUA. Conclusions SUA independently predicts adverse outcomes in HFpEF. Sacubitril/valsartan significantly reduces SUA compared to valsartan, an effect that was stronger in those with higher baseline SUA, and reducing SUA was associated with improved outcomes.

<b><i>Introduction:</i></b> The evidence that blood levels of the soluble receptor for advanced glycation end products (sRAGE) predict mortality in people with cardiovascular diseases (CVD) is inconsistent. To clarify this matter, we investigated if frailty status influences this association. <b><i>Methods:</i></b> We analysed data of 1,016 individuals (median age, 75 years) from 3 population-based European cohorts, enrolled in the FRAILOMIC project. Participants were stratified by history of CVD and frailty status. Mortality was recorded during 8 years of follow-up. <b><i>Results:</i></b> In adjusted Cox regression models, baseline serum sRAGE was positively associated with an increased risk of mortality in participants with CVD (HR 1.64, 95% CI 1.09–2.49, <i>p</i> = 0.019) but not in non-CVD. Within the CVD group, the risk of death was markedly enhanced in the frail subgroup (CVD-F, HR 1.97, 95% CI 1.18–3.29, <i>p</i> = 0.009), compared to the non-frail subgroup (CVD-NF, HR 1.50, 95% CI 0.71–3.15, <i>p</i> = 0.287). Kaplan-Meier analysis showed that the median survival time of CVD-F with high sRAGE (&#x3e;1,554 pg/mL) was 2.9 years shorter than that of CVD-F with low sRAGE, whereas no survival difference was seen for CVD-NF. Area under the ROC curve analysis demonstrated that for CVD-F, addition of sRAGE to the prediction model increased its prognostic value. <b><i>Conclusions:</i></b> Frailty status influences the relationship between sRAGE and mortality in older adults with CVD. sRAGE could be used as a prognostic marker of mortality for these individuals, particularly if they are also frail.

Abstract Background. Oxidative stress (OS) and inflammation are major mechanisms involved in the progression of chronic heart failure (CHF). Serum uric acid (sUA) is related to CHF severity and could represent a marker of xanthine-oxidase activation. The relationship between sUA, oxidative stress (OS) and inflammation markers was assessed in patients with moderate-severe CHF and reduced left ventricular (LV) ejection fraction (EF). Methods. In 57 patients with stable CHF, functional NYHA class III, with EF<40%, the LV function was assessed by N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) levels and echocardiographically through the EF and E/e’ ratio, a marker of LV filling pressures. The relationship between LV function, sUA, malondialdehyde (MDA), myeloperoxidase (MPO), paraoxonase 1 (PON-1) as OS markers and high sensitivity C-reactive protein (hsCRP) and interleukin 6 (IL-6) as markers of systemic inflammation was evaluated. Results. The mean sUA level was 7.9 ± 2.2 mg/dl, and 61% of the CHF patients had hyperuricemia. CHF patients with elevated LV filling pressures (E/e’ ≥ 13) had higher sUA (8.6 ± 2.3 vs. 7.3 ± 1.4, p=0.08) and NT-proBNP levels (643±430 vs. 2531±709, p=0.003) and lower EF (29.8 ± 3.9 % vs. 36.3 ± 4.4 %, p=0.001). There was a significant correlation between sUA and IL-6 (r = 0.56, p<0.001), MDA (r= 0.49, p= 0.001), MPO (r=0.34, p=0.001) and PON-1 levels (r= −0.39, p= 0.003). Conclusion. In CHF, hyperuricemia is associated with disease severity. High sUA levels in CHF with normal renal function may reflect increased xanthine-oxidase activity linked with chronic inflammatory response.

BackgroundThe risk of death and complications after major trauma in patients with chronic kidney disease (CKD) is higher than in the general population, but whether this association holds true among Canadian trauma patients is unknown.ObjectivesTo characterize patients with CKD/receiving dialysis within a regional major trauma cohort and compare their outcomes with patients without CKD.MethodsAll major traumas requiring hospitalization between 2006 and 2017 were identified from a provincial trauma registry in Nova Scotia, Canada. Trauma patients with stage ≥3 CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2) or receiving dialysis were identified by cross-referencing two regional databases for nephrology clinics and dialysis treatments. The primary outcome was in-hospital mortality; secondary outcomes included hospital/intensive care unit (ICU) length of stay (LOS) and ventilator-days. Cox regression was used to adjust for the effects of patient characteristics on in-hospital mortality.ResultsIn total, 6237 trauma patients were identified, of whom 4997 lived within the regional nephrology catchment area. CKD/dialysis trauma patients (n=101; 28 on dialysis) were older than patients without CKD (n=4896), with higher rates of hypertension, diabetes, and cardiovascular disease, and had increased risk of in-hospital mortality (31% vs 11%, p<0.001). No differences were observed in injury severity, ICU LOS, or ventilator-days. After adjustment for age, sex, and injury severity, the HR for in-hospital mortality was 1.90 (95% CI 1.33 to 2.70) for CKD/dialysis compared with patients without CKD.ConclusionIndependent of injury severity, patients without CKD/dialysis have significantly increased risk of in-hospital mortality after major trauma.
