Abstract
The role of sacubitril and/or valsartan in patient with heart failure (HF) is established. Whether sacubitril and/or valsartan plays a role in improving outcomes in patients after ST-segment elevation myocardial infarction (STEMI) is unknown. The current study aims to comparing the efficacy and safety of sacubitril and/or valsartan versus ramipril in post-STEMI patients. Patients presenting with STEMI were randomized to receive either sacubitril and/or valsartan or ramipril after primary percutaneous coronary intervention. The main efficacy endpoint was major adverse cardiac events (MACE) at 30 days and 6 months, defined as a composite of cardiac death, myocardial infarction, and HF hospitalizations. Multiple secondary clinical safety and efficacy endpoints were examined. A total of 200 patients were randomized from January 2018 to March 2019, mean age 54.5±10.4, 87% men, 75% presented with anterior wall STEMI. Baseline clinical and echocardiographic characteristics were comparable between groups. The primary endpoint of MACE was similar with sacubitril/valsartan versus ramipril at 30 days (p = 0.18); however, at 6 months, sacubitril/valsartan was associated with significant reduction of MACE (p = 0.005), mainly driven by reduction in HF hospitalizations (18% vs 36%, OR 0.40, 95% 0.22 to 0.75; p = 0.004). At 6 months, LV ejection fraction was higher with sacubitril/valsartan (46.8±12.5% vs 42.09±13.8%; p = 0.012), with improved LV remodelling (LV end diastolic dimension 50.6±3.9 mm vs 53.2±2.7 mm, p = 0.047; and LV end systolic dimension 36.1±3.4 mm versus 39.9±6.3 mm, p = 0.001) compared with ramipril. No difference in other efficacy or safety clinical endpoints was observed. In conclusion, early initiation of sacubitril/valsartan may offer clinical benefit and improvement in myocardial remodelling in post-STEMI patients.

Abstract
PURPOSE Patients affected by heart failure with reduced ejection fraction (HFrEF) receive clinical and functional beneficial effects from treatment with sacubitril/valsartan. However previous studies have shown that patients with an implantable cardioverter defibrillator (ICD) could obtain even greater benefit, but only make up a only a small proportion of patients. In the current study we evaluated the effect of sacubitril/valsartan in patients with an ICD. METHODS Thirty-five outpatients with HFrEF (aged 60 ± 11 years, 28 were males), on optimal medical therapy were studied. All patients received an ICD at least 6 months before enrollment or were non-responders to ICD plus resynchronization (CRT-D). An open-label sacubitril/valsartan treatment was established at the maximum tolerated dose. Clinical assessment, 6-min walk test (6MWT) and echocardiography, were performed during follow-up at 90, 180, and 360 days. Quality of life score and perceived fatigue on exercise were assessed. RESULTS Clinical conditions dramatically improved in most patients, especially within the first 6 months of therapy (76 % were in NYHA-I and 24 % in NYHA-II at the end of study vs 71 % NYHA-II and 29 % NYHA III at enrollment, p < 0.001). Quality of life and exercise performance significantly improved according to N-terminal pro-brain natriuretic peptide (NT-proBNP) serum levels lowering. Walking distance at 6MWT increased from 274 ± 97 to 389 ± 53 m and walking speed from 0.74 ± 0.27 to 1.07 ± 0.15 m/s (p < 0.001), while oxygen saturation did not differ significantly (from 90 ± 1 % to 91 ± 2 %). More gradual was left ventricular reverse remodeling. Ejection fraction improved mildly (+ 5 points %, p < 0.001). Global longitudinal strain and diastolic function were also assessed over time. CONCLUSION Sacubitril/valsartan therapy for HFrEF may lead to significant clinical and functional improvements even in patients with ICD at greater arrhythmic risk. Clinical improvement is obtained within the first 6 months of treatment while reverse remodeling needs more time.

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
BACKGROUND Given the association of diabetic retinopathy (DR) and kidney disease, we investigated the urinary peptidome to presence and deterioration of DR in a post hoc analysis of trials investigating the effect of candesartan on progression of DR in type 1 and type 2 diabetes, respectively. METHODS Baseline urinary peptidomic analysis was performed on a random selection of 783 and 792 subjects in two randomized controlled trials, DIRECT-Protect 1 and 2, respectively. End points were two-step (RET2) and three-step (RET3) change in Early Treatment of Diabetic Retinopathy Study protocol (ETDRS) defined level. Peptide levels were correlated to baseline EDTRS level in a discovery set of 2/3 of the participants from DIRECT-Protect 1. The identified peptides were then validated cross-sectionally in the remaining 1/3 from DIRECT-Protect 1. Thereafter, peptides identified in the discovery set were assessed in the entire DIRECT-Protect 1 and 2 cohorts and significant peptides were tested longitudinally. RESULTS Follow-up ranged 4.0-4.7 years. 24 peptides were associated with baseline DR in the discovery set. COL3A1 (seq: NTG~) and COL4A1 (seq: DGA~) were associated with baseline DR in the validation set (Rho: -.223, p < 0.001 and Rho: -.141, p = 0.024). Neither was significantly associated with end points. Assessing the 24 identified peptides in the entire cohorts, several collagen peptides were associated with baseline DR and end points; however, there was no overlap across diabetes types. CONCLUSIONS We identified several urinary peptides (mainly collagen) associated with the presence of DR, however they could not be conclusively associated with worsening of DR.

Abstract
BACKGROUND Despite the progress in the treatment of heart failure with reduced ejection fraction (HFrEF), the prognosis remains unfavorable. OBJECTIVES To evaluate the effectiveness, tolerance and safety after one-year follow-up of Polish patients with stable chronic HFrEF treated with sacubitril/valsartan. MATERIAL AND METHODS This was an observational multicenter study conducted in 3 centers (Kraków, Łódź and Warszawa) specializing in heart failure (HF). We enrolled 89 HFrEF patients (aged 59.3 ±13.5 years, 82% males) in NYHA class II-IV (ambulatory). Clinical, laboratory and echocardiographic parameters were evaluated at baseline and after a one-year follow-up. The composite endpoint was defined as death or urgent HF hospitalization. RESULTS After 1 year, 80% of patients used 50% or more of the target dose of sacubitril/valsartan. After a year of treatment, there were significant improvements of HF symptoms, N-terminal prohormone B-type natriuretic peptide (NT proBNP), ejection fraction (EF), and distance in six-minute walk test (6MWP) (all p < 0.001). Patients treated with the highest dose of sacubitril/valsartan exhibited the greatest benefits. The safety profile was favorable and consistent with that previously reported; however, therapy discontinuation due to side effects occurred in 11% of patients. The independent predictors for composite endpoint (n = 24, 26.9%) were history of HF hospitalization, tricuspid annular plane systolic excursion (TAPSE) and angiotensin-converting-enzyme inhibitor (ACEI)-naive patients. CONCLUSIONS Treatment of chronic HFrEF patients with sacubitril/valsartan is safe and is associated with significant clinical and objective improvement. The non-survivors had more advanced HF, so the initiation and uptitration of sacubitril/valsartan should be done early.

Abstract
The noninvasive assessment of myocardial work (MW) by pressure-strain loops analysis (PSL) is a relative new tool for the evaluation of myocardial performance. Sacubitril/Valsartan is a treatment for heart failure with reduced ejection fraction (HFrEF) which has a spectacular effect on the reduction of cardiovascular events (major adverse cardiovascular events [MACEs]). This study aimed to evaluate the short- and medium-term effect of Sacubitril/Valsartan treatment on MW parameters and the prognostic value of MW in this specific group of patients. Seventy-nine patients with HFrEF (mean age: 66 ± 12 years; LV ejection fraction: 28% ± 9%) were prospectively included in the study and treated with Sacubitril/Valsartan. Echocardiographic examination was performed at baseline, and after 6- and 12-month of therapy with Sacubitril/Valsartan. Sacubitril/Valsartan significantly increased myocardial constructive work (CW) (1023 ± 449 vs 1424 ± 484 mm Hg%, p <0.0001) and myocardial work efficiency (WE) [87 (78to 90) vs 90 (86 to 95), p <0.0001]. During FU (2.6 ± 0.9 years), MACEs occurred in 13 (16%) patients. After correction for LV size, LV ejection fraction and WE, global myocardial constructive work (CW) was the only predictor of MACEs [hazard ratio [HR] 0.99 (0.99 to 1.00), p = 0.04]. A CW <910 mm Hg identified patients at particularly increase risk of MACEs [HR 11.09 (1.45 to 98.94), p = 0.002, log-rank test p <0.0001]. In conclusion, in patients with HFrEF who receive a comprehensive background beta-blocker and mineral-corticoid receptor antagonist therapy, Sacubitril/Valsartan induces a significant improvement of myocardial CW and WE. In this population, the estimation of CW before the initiation of Sacubitril/Valsartan allows the prediction of MACEs.

Abstract
BACKGROUND Myocardial fibrosis may contribute to the pathophysiology of heart failure with preserved ejection fraction. Given the biochemical targets of sacubitril/valsartan, this study hypothesized that circulating biomarkers reflecting the mechanisms that determine extracellular matrix homeostasis are altered by sacubitril/valsartan compared with valsartan alone. OBJECTIVES This study investigated the effects of sacubitril/valsartan on biomarkers of extracellular matrix homeostasis and the association between biomarkers and the primary endpoint (total heart failure hospitalizations and cardiovascular death). METHODS N-terminal propeptide of collagen I and III, tissue inhibitor of matrix metalloproteinase 1, carboxyl-terminal telopeptide of collagen type I, and soluble ST2 were measured at baseline (n = 1,135) and 16 (n = 1,113) and 48 weeks (n = 1,016) after randomization. The effects of sacubitril/valsartan on these biomarkers were compared with those of valsartan alone. Baseline biomarker values and changes from baseline to 16 weeks were related to primary endpoint. RESULTS At baseline, all 5 biomarkers were higher than published referent control values. Sixteen weeks after randomization, sacubitril/valsartan decreased tissue inhibitor of matrix metalloproteinase 1 by 8% (95% confidence interval [CI]: 6% to 10%; p < 0.001), soluble ST2 by 4% (95% CI: 1% to 7%; p = 0.002), and N-terminal propeptide of collagen III by 3% (95% CI: 0% to 6%; p = 0.04) and increased carboxyl-terminal telopeptide of collagen type I by 4% (95% CI: 1% to 8%; p = 0.02) compared with valsartan alone, consistently in men and women and patients with left ventricular ejection fraction above or below the median of 57%. Higher levels of tissue inhibitor of matrix metalloproteinase 1 and soluble ST2 at baseline and increases in these markers at 16 weeks were associated with higher primary endpoint event rates. CONCLUSIONS Biomarkers reflecting extracellular matrix homeostasis are elevated in heart failure with preserved ejection fraction, favorably altered by sacubitril/valsartan, and have important prognostic value.

Abstract
BACKGROUND In heart failure with reduced ejection fraction (HFrEF), elevated soluble neprilysin (sNEP) levels are associated with an increased risk of cardiovascular death, and its inhibition with sacubitril/valsartan has improved survival. OBJECTIVES This study sought to determine the relevance of sNEP as a biomarker in heart failure with preserved ejection fraction (HFpEF) and to compare circulating sNEP levels in patients with HFpEF with normal controls. METHODS A case-control study was performed in 242 symptomatic patients with HFpEF previously enrolled in the Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure with Preserved Ejection Fraction (RELAX) and Nitrates's Effect on Activity Tolerance in Heart Failure With Preserved Ejection (NEAT-HFpEF) clinical trials and 891 asymptomatic subjects without HF or diastolic dysfunction (confirmed by NT-proBNP levels <200 pg/ml and echocardiography) who were enrolled in the Prevalence of Asymptomatic Left Ventricular Dysfunction study. sNEP was measured using a sandwich enzyme-linked immunosorbent assay (ELISA) in all subjects. RESULTS Overall, sNEP levels were lower in HFpEF compared with controls (3.5 ng/ml; confidence interval [CI]: 2.5 to 4.8 vs. 8.5 ng/ml; CI: 7.2 to 10.0; p < 0.001). After adjusting for age, gender, body mass index (BMI), and smoking history, mean sNEP levels were also lower in HFpEF compared with controls (4.0 ng/ml [CI: 2.7 to 5.4] vs. 8.2 ng/ml [CI: 6.8 to 9.7]; p = 0.002). The cohorts were propensity matched based on age, BMI, diabetes, hypertension, smoking history, and renal function, and sNEP levels remained lower in HFpEF compared with controls (median 2.4 ng/ml [interquartile range: 0.6 to 27.7] vs. 4.9 ng/ml [interquartile range: 1.2 to 42.2]; p = 0.02). CONCLUSIONS Patients with HFpEF on average have significantly lower circulating sNEP levels compared with controls. These findings challenge our current understanding of the complex biology of circulating sNEP in HFpEF.
