Abstract
This study aimed to investigate the effects of the basic treatment for heart failure and sequential treatment with rh-brain natriuretic peptide (rhBNP) alone or the combination of rhBNP and sacubitril/valsartan. Cardiac structure, pulmonary artery pressure, inflammation and oxidative stress in patients with acute heart failure were evaluated.Three hundred patients with acute heart failure were included. According to the random number table method, the patients were divided into 3 groups of 100 patients per group: the standard treatment group (treated with an angiotensin-converting enzyme inhibitor, β receptor blocker, and corticosteroid antagonist), rhBNP group (basic treatment combined with rhBNP) and sequential treatment group (basic treatment for heart failure combined with rhBNP followed by sacubitril/valsartan). The changes in NT-probrain natriuretic peptide (BNP) levels, cardiac troponin T (cTnT) levels, cardiac structure, pulmonary artery pressure, and the levels inflammatory factors and oxidative stress factors were compared among the 3 groups at 1, 4, 12, and 36 weeks after treatment.The sequential treatment group displayed superior outcomes than the standard treatment group and the rhBNP group in terms of left atrium diameter, left ventricular end diastolic volume, left ventricular ejection fraction, pulmonary artery pressure, NT-proBNP levels, and cTnT levels, which respond to damage to the heart structure and myocardium. This result may be related to the decreased levels of inflammatory factors and the correction of oxidative stress imbalance.Sacubitril/valsartan significantly reduce the serum levels of inflammatory factors in patients with acute heart failure while decreasing the levels of oxidizing factors and increasing the levels of antioxidant factors. These changes may be one of the explanations for the better cardiac structure and better pulmonary artery pressure observed in the sequential treatment group.

Abstract
IMPORTANCE There is limited evidence on the benefits of sacubitril/valsartan vs broader renin angiotensin system inhibitor background therapy on surrogate outcome markers, 6-minute walk distance, and quality of life in patients with heart failure and mildly reduced or preserved left ventricular ejection fraction (LVEF >40%). OBJECTIVE To evaluate the effect of sacubitril/valsartan on N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, 6-minute walk distance, and quality of life vs background medication-based individualized comparators in patients with chronic heart failure and LVEF of more than 40%. DESIGN, SETTING, AND PARTICIPANTS A 24-week, randomized, double-blind, parallel group clinical trial (August 2017-October 2019). Of 4632 patients screened at 396 centers in 32 countries, 2572 patients with heart failure, LVEF of more than 40%, elevated NT-proBNP levels, structural heart disease, and reduced quality of life were enrolled (last follow-up, October 28, 2019). INTERVENTIONS Patients were randomized 1:1 either to sacubitril/valsartan (n = 1286) or to background medication-based individualized comparator (n = 1286), ie, enalapril, valsartan, or placebo stratified by prior use of a renin angiotensin system inhibitor. MAIN OUTCOMES AND MEASURES Primary end points were change from baseline in plasma NT-proBNP level at week 12 and in the 6-minute walk distance at week 24. Secondary end points were change from baseline in quality of life measures and New York Heart Association (NYHA) class at 24 weeks. RESULTS Among 2572 randomized patients (mean age, 72.6 years [SD, 8.5 years]; 1301 women [50.7%]), 2240 (87.1%) completed the trial. At baseline, the median NT-proBNP levels were 786 pg/mL in the sacubitril/valsartan group and 760 pg/mL in the comparator group. After 12 weeks, patients in the sacubitril/valsartan group (adjusted geometric mean ratio to baseline, 0.82 pg/mL) had a significantly greater reduction in NT-proBNP levels than did those in the comparator group (adjusted geometric mean ratio to baseline, 0.98 pg/mL) with an adjusted geometric mean ratio of 0.84 (95% CI, 0.80 to 0.88; P < .001). At week 24, there was no significant between-group difference in median change from baseline in the 6-minute walk distance with an increase of 9.7 m vs 12.2 m (adjusted mean difference, -2.5 m; 95% CI, -8.5 to 3.5; P = .42). There was no significant between-group difference in the mean change in the Kansas City Cardiomyopathy Questionnaire clinical summary score (12.3 vs 11.8; mean difference, 0.52; 95% CI, -0.93 to 1.97) or improvement in NYHA class (23.6% vs 24.0% of patients; adjusted odds ratio, 0.98; 95% CI, 0.81 to 1.18). The most frequent adverse events in the sacubitril/valsartan group vs the comparator group were hypotension (14.1% vs 5.5%), albuminuria (12.3% vs 7.6%), and hyperkalemia (11.6% vs 10.9%). CONCLUSIONS AND RELEVANCE Among patients with heart failure and left ventricular ejection factor of higher than 40%, sacubitril/valsartan treatment compared with standard renin angiotensin system inhibitor treatment or placebo resulted in a significantly greater decrease in plasma N-terminal pro-brain natriuretic peptide levels at 12 weeks but did not significantly improve 6-minute walk distance at 24 weeks. Further research is warranted to evaluate potential clinical benefits of sacubitril/valsartan in these patients. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03066804.

Abstract
BACKGROUND The DASH (Dietary Approaches to Stop Hypertension) diet has been determined to have beneficial effects on cardiac biomarkers. The effects of sodium reduction on cardiac biomarkers, alone or combined with the DASH diet, are unknown. OBJECTIVES The purpose of this study was to determine the effects of sodium reduction and the DASH diet, alone or combined, on biomarkers of cardiac injury, strain, and inflammation. METHODS DASH-Sodium was a controlled feeding study in adults with systolic blood pressure (BP) 120 to 159 mm Hg and diastolic BP 80 to 95 mm Hg, randomly assigned to the DASH diet or a control diet. On their assigned diet, participants consumed each of three sodium levels for 4 weeks. Body weight was kept constant. At the 2,100 kcal level, the 3 sodium levels were low (50 mmol/day), medium (100 mmol/day), and high (150 mmol/day). Outcomes were 3 cardiac biomarkers: high-sensitivity cardiac troponin I (hs-cTnI) (measure of cardiac injury), N-terminal pro-B-type natriuretic peptide (NT-proBNP) (measure of strain), and high-sensitivity C-reactive protein (hs-CRP) (measure of inflammation), collected at baseline and at the end of each feeding period. RESULTS Of the original 412 participants, the mean age was 48 years; 56% were women, and 56% were Black. Mean baseline systolic/diastolic BP was 135/86 mm Hg. DASH (vs. control) reduced hs-cTnI by 18% (95% confidence interval [CI]: -27% to -7%) and hs-CRP by 13% (95% CI: -24% to -1%), but not NT-proBNP. In contrast, lowering sodium from high to low levels reduced NT-proBNP independently of diet (19%; 95% CI: -24% to -14%), but did not alter hs-cTnI and mildly increased hs-CRP (9%; 95% CI: 0.4% to 18%). Combining DASH with sodium reduction lowered hs-cTnI by 20% (95% CI: -31% to -7%) and NT-proBNP by 23% (95% CI: -32% to -12%), whereas hs-CRP was not significantly changed (-7%; 95% CI: -22% to 9%) compared with the high sodium-control diet. CONCLUSIONS Combining a DASH dietary pattern with sodium reduction can lower 2 distinct mechanisms of subclinical cardiac damage: injury and strain, whereas DASH alone reduced inflammation.

Abstract
BACKGROUND Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of a deterioration in heart failure (HF) and mortality in patients with a broad range of cardiovascular risks. Recent guidelines recommend considering the use of SGLT2 inhibitors in patients with type 2 diabetes (T2D) and HF, irrespective of their glycemic control status and background use of other glucose-lowering agents including metformin. However, only a small number of studies have investigated whether the effects of SGLT2 inhibitor in these patients differ by the concomitant use of other glucose-lowering agents. METHODS This was a post-hoc analysis of the CANDLE trial (UMIN000017669), an investigator-initiated, multicenter, open-label, randomized, controlled trial. The primary aim of the analysis was to assess the effect of 24 weeks of treatment with canagliflozin, relative to glimepiride, on N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration in patients with T2D and clinically stable chronic HF. In the present analysis, the effect of canagliflozin on NT-proBNP concentration was assessed in the patients according to their baseline use of other glucose-lowering agents. RESULTS Almost all patients in the CANDLE trial presented as clinically stable (New York Heart Association class I to II), with about 70% of participants having HF with a preserved ejection fraction phenotype (defined as a left ventricular ejection fraction ≥ 50%) at baseline. Of the 233 patients randomized to either canagliflozin (100 mg daily) or glimepiride (starting dose 0.5 mg daily), 85 (36.5%) had not been taking any glucose-lowering agents at baseline (naïve). Of the 148 patients who had been taking at least one glucose-lowering agent at baseline (non-naïve), 44 (29.7%) and 127 (85.8%) had received metformin or a dipeptidyl dipeptidase-4 (DPP-4) inhibitor, respectively. The group ratio (canagliflozin vs. glimepiride) of proportional changes in the geometric means of NT-proBNP concentration was 0.95 (95% confidence interval [CI] 0.76 to 1.18, p = 0.618) for the naïve subgroup, 0.92 (95% CI 0.79 to1.07, p = 0.288) for the non-naïve subgroup, 0.90 (95% CI 0.68 to 1.20, p = 0.473) for the metformin-user subgroup, and 0.91 (95% CI 0.77 to 1.08, p = 0.271) for the DPP-4 inhibitor-user subgroup. No heterogeneity in the effect of canagliflozin, relative to glimepiride, on NT-proBNP concentration was observed in the non-naïve subgroups compared to that in the naïve subgroup. CONCLUSION The impact of canagliflozin treatment on NT-proBNP concentration appears to be independent of the background use of diabetes therapy in the patient population examined.

Abstract
BACKGROUND The relationship between the benefits of empagliflozin in heart failure with reduced ejection fraction (HFrEF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) has not been reported. OBJECTIVES The authors sought to evaluate the relationship between NT-proBNP and empagliflozin effects in EMPEROR-Reduced (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Reduced Ejection Fraction). METHODS Patients with HFrEF were randomly assigned to placebo or empagliflozin 10 mg daily. NT-proBNP was measured at baseline, 4 weeks, 12 weeks, 52 weeks, and 100 weeks. Patients were divided into quartiles of baseline NT-proBNP. RESULTS Incidence rates for each study outcome were 4- to 6-fold higher among those in the highest versus lowest NT-proBNP quartiles (≥3,480 vs <1,115 pg/mL). Study participants with higher NT-proBNP had 2- to 3-fold total hospitalizations higher than the lowest NT-proBNP quartile. Empagliflozin reduced risk for major cardiorenal events without heterogeneity across NT-proBNP quartiles (primary endpoint Pinteraction = 0.94; renal composite endpoint Pinteraction = 0.71). Empagliflozin treatment significantly reduced NT-proBNP at all timepoints examined; by 52 weeks, the adjusted mean difference from placebo was 13% (P < 0.001). An NT-proBNP in the lowest quartile (<1,115 pg/mL) 12 weeks after randomization was associated with lower risk for subsequent cardiovascular death or heart failure hospitalization regardless of baseline concentration. Treatment with empagliflozin resulted in 27% higher adjusted odds of an NT-proBNP concentration of <1,115 pg/mL by 12 weeks compared with placebo (P = 0.01). CONCLUSIONS In EMPEROR-Reduced, higher baseline NT-proBNP concentrations were associated with greater risk for adverse heart failure or renal outcomes, but empagliflozin reduced risk regardless of baseline NT-proBNP concentration. The NT-proBNP concentration after treatment with empagliflozin better informs subsequent prognosis than pretreatment concentrations.

Abstract
BACKGROUND Identification of the effective subtypes of treatment for heart failure (HF) is an essential topic for optimizing treatment of the disorder. We hypothesized that the beneficial effect of SGLT2 inhibitors (SGLT2i) on the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) might depend on baseline diastolic function. To elucidate the effects of SGLT2i in type 2 diabetes mellitus (T2DM) and chronic HF we investigated, as a post-hoc sub-study of the CANDLE trial, the effects of canagliflozin on NT-proBNP levels from baseline to 24 weeks, with the data stratified by left ventricular (LV) diastolic function at baseline. METHODS Patients (n = 233) in the CANDLE trial were assigned randomly to either an add-on canagliflozin (n = 113) or glimepiride treatment groups (n = 120). The primary endpoint was a comparison between the two groups of the changes from baseline to 24 weeks in NT-pro BNP levels, stratified according to baseline ventricular diastolic function. RESULTS The change in the geometric mean of NT-proBNP level from baseline to 24 weeks was 0.98 (95% CI 0.89-1.08) in the canagliflozin group and 1.07 (95% CI 0.97-1.18) in the glimepiride group. The ratio of change with canagliflozin/glimepiride was 0.93 (95% CI 0.82-1.05). Responder analyses were used to investigate the response of an improvement in NT-proBNP levels. Although the subgroup analyses for septal annular velocity (SEP-e') showed no marked heterogeneity in treatment effect, the subgroup with an SEP-e' < 4.7 cm/s indicated there was an association with lower NT-proBNP levels in the canagliflozin group compared with that in the glimepiride group (ratio of change with canagliflozin/glimepiride (0.83, 95% CI 0.66-1.04). CONCLUSIONS In the subgroup with a lower LV diastolic function, canagliflozin showed a trend of reduced NT-pro BNP levels compared to that observed with glimepiride. This study suggests that the beneficial effects of canagliflozin treatment may be different in subgroups classified by the severity of LV diastolic dysfunction.

Abstract
AIMS/HYPOTHESIS Interventions that reduce inflammation may delay progression of microvascular and macrovascular complications in diabetes. We examined the effects of vitamin D3 and/or n-3 fatty acid supplementation vs placebo on 5 year changes in serum inflammatory and cardiac biomarkers in adults with type 2 diabetes. METHODS This study reports pre-specified secondary outcomes of the Vitamin D and Omega-3 Trial to Prevent and Treat Diabetic Kidney Disease, in which 1312 US adults with type 2 diabetes and without known cardiovascular disease, malignancy, or end-stage kidney disease were randomised using computer-generated random numbers in blocks of eight to vitamin D3 (2000 IU/day) vs placebo and n-3 fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]; 1 g/day) vs placebo in a 2 × 2 factorial design. Participants, examiners, and researchers assessing outcomes were blinded to intervention assignment. We measured serum IL-6, high-sensitivity C-reactive protein (hsCRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) at baseline and after 2 and 5 years. RESULTS A total of 333 participants were randomised to vitamin D3 and placebo n-3 fatty acids, 289 to n-3 fatty acids and placebo vitamin D3, 370 to vitamin D3 and n-3 fatty acids, and 320 to 2 placebos; 989 (75%) and 934 (71%) participants returned blood samples at 2 and 5 years, respectively. Participants had a mean age of 67.6 years (46% women). Overall, baseline geometric means of IL-6, hsCRP and NT-proBNP were 1.2 pg/ml, 1.9 mg/l and 262 ng/l, respectively. After 5 years, mean IL-6 and hsCRP remained within 6% of their baseline values while mean NT-proBNP increased by 55% overall. Compared with placebo, participants assigned to vitamin D3 had a 1.24-fold greater increase in NT-proBNP over 5 years (95% CI 1.09, 1.41; p = 0.003), while IL-6 and hsCRP did not have a significant difference in change. Comparing n-3 fatty acids with placebo, there was no significant difference in change in IL-6, hsCRP or NT-proBNP. No heterogeneity was observed in subgroup analyses accounting for baseline eGFR, urine albumin to creatinine ratio, initial biomarker concentration, 25-hydroxyvitamin D level or EPA+DHA index. CONCLUSIONS/INTERPRETATION Among adults with type 2 diabetes, supplementation with vitamin D3 or n-3 fatty acids did not reduce IL-6, hsCRP or NT-proBNP over 5 years.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a common comorbidity in heart failure with reduced ejection fraction, associated with undertreatment and worse outcomes. New treatments for heart failure with reduced ejection fraction may be particularly important in patients with concomitant COPD. Methods and Results We examined outcomes in 8399 patients with heart failure with reduced ejection fraction, according to COPD status, in the PARADIGM-HF (Prospective Comparison of Angiotensin Receptor Blocker-Neprilysin Inhibitor With Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial. Cox regression models were used to compare COPD versus non-COPD subgroups and the effects of sacubitril/valsartan versus enalapril. Patients with COPD (n=1080, 12.9%) were older than patients without COPD (mean 67 versus 63 years; P<0.001), with similar left ventricular ejection fraction (29.9% versus 29.4%), but higher NT-proBNP (N-terminal pro-B-type natriuretic peptide; median, 1741 pg/mL versus 1591 pg/mL; P=0.01), worse functional class (New York Heart Association III/IV 37% versus 23%; P<0.001) and Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (73 versus 81; P<0.001), and more congestion and comorbidity. Medical therapy was similar in patients with and without COPD except for beta-blockade (87% versus 94%; P<0.001) and diuretics (85% versus 80%; P<0.001). After multivariable adjustment, COPD was associated with higher risks of heart failure hospitalization (hazard ratio [HR], 1.32; 95% CI, 1.13-1.54), and the composite of cardiovascular death or heart failure hospitalization (HR, 1.18; 95% CI, 1.05-1.34), but not cardiovascular death (HR, 1.10; 95% CI, 0.94-1.30), or all-cause mortality (HR, 1.14; 95% CI, 0.99-1.31). COPD was also associated with higher risk of all cardiovascular hospitalization (HR, 1.17; 95% CI, 1.05-1.31) and noncardiovascular hospitalization (HR, 1.45; 95% CI, 1.29-1.64). The benefit of sacubitril/valsartan over enalapril was consistent in patients with and without COPD for all end points. Conclusions In PARADIGM-HF, COPD was associated with lower use of beta-blockers and worse health status and was an independent predictor of cardiovascular and noncardiovascular hospitalization. Sacubitril/valsartan was beneficial in this high-risk subgroup. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT01035255.

Abstract
AIMS: To investigate the effect of the sodium-glucose co-transporter-2 inhibitor empagliflozin on N-terminal pro-b-type natriuretic peptide (NT-proBNP) in patients with heart failure (HF) and reduced ejection fraction (HFrEF). METHODS AND RESULTS Empire HF was an investigator-initiated, multi-center, double-blinded, placebo-controlled, randomized trial. Patients with mildly symptomatic HFrEF, mean (standard deviation (SD)) age 64 (11) years, 85% male, and mean left ventricular ejection fraction 29% (8), on recommended HF therapy were assigned to receive either empagliflozin 10 mg once daily or placebo for 12 weeks. The primary endpoint was the between-group difference in the change of NT-proBNP from baseline to 12 weeks. In total, 95 patients were assigned to empagliflozin and 95 to placebo. No significant difference in the change of NT-proBNP with empagliflozin versus placebo was observed [Empagliflozin: baseline, median (interquartile range (IQR)) 582 (304-1020) pg/mL, 12 weeks, 478 (281-961) pg/mL; Placebo: baseline, 605 (322-1070) pg/mL, 12 weeks, 520 (267-1075) pg/mL, adjusted ratio of change empagliflozin/placebo 0.98; 95% confidence interval (CI) 0.82-1.11, P = 0.7]. Further, no significant difference was observed in accelerometer-measured daily activity level [adjusted mean difference of change, empagliflozin versus placebo, -26.0 accelerometer counts; 95% CI -88.0 to 36.0, P = 0.4] or Kansas City Cardiomyopathy Questionnaire Overall Summary Score [adjusted mean difference of change, empagliflozin versus placebo 0.8; 95% CI -2.3 to 3.9, P = 0.6]. CONCLUSION In low-risk patients with HFrEF with mild symptoms and on recommended HF therapy, empagliflozin did not change NT-proBNP after 12 weeks. Further, no change in daily activity level or health status was observed.

Abstract
Background Effects of sodium-glucose cotransporter 2 inhibitors on reducing hospitalization for heart failure have been reported in randomized controlled trials, but their effects on patients with heart failure with preserved ejection fraction (HFpEF) are unknown. This study aimed to evaluate the drug efficacy of luseogliflozin, a sodium-glucose cotransporter 2 inhibitor, in patients with type 2 diabetes mellitus and HFpEF. Methods and Results We performed a multicenter, open-label, randomized, controlled trial for comparing luseogliflozin 2.5 mg once daily with voglibose 0.2 mg 3 times daily in patients with type 2 diabetes mellitus suffering from HFpEF (left ventricular ejection fraction >45% and BNP [B-type natriuretic peptide] concentrations ≥35 pg/mL) in a 1:1 randomization fashion. The primary outcome was the difference from baseline in BNP levels after 12 weeks of treatment between the 2 drugs. A total of 173 patients with diabetes mellitus and HFpEF were included. Of these, 83 patients were assigned to receive luseogliflozin and 82 to receive voglibose. There was no significant difference in the reduction in BNP concentrations after 12 weeks from baseline between the 2 groups. The ratio of the mean BNP value at week 12 to the baseline value was 0.79 in the luseogliflozin group and 0.87 in the voglibose group (percent change, -9.0% versus -1.9%; ratio of change with luseogliflozin versus voglibose, 0.93; 95% CI, 0.78-1.10; P=0.26). Conclusion In patients with type 2 diabetes mellitus and HFpEF, there is no significant difference in the degree of reduction in BNP concentrations after 12 weeks between luseogliflozin and voglibose.
