Aims: The effect of the angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril-valsartan in patients with heart failure with preserved ejection fraction (HFpEF) remains unclear, and data on ARNI treatment in peritoneal dialysis (PD) patients are lacking. The present study was designed to assess the efficacy and safety of sacubitril-valsartan in patients with HFpEF undergoing peritoneal dialysis.Methods and Results: End-stage kidney disease (ESKD) patients undergoing PD for 3 months with New York Heart Association (NYHA) class II–IV heart failure, ejection fraction of 50% or higher, and elevated levels of N-terminal pro–B-type natriuretic peptide (NT-proBNP) were assigned to receive sacubitril-valsartan. Patients were followed up regularly after medication treatment. The alterations in clinical and biochemical parameters before and after taking sacubitril-valsartan (generally 50–100 mg b.i.d) were investigated, and safety was also assessed. Twenty-one patients were recruited in this study. Compared with baseline levels, NT-proBNP levels [9769.0 (3093.5–21941.0) vs. 3034.0 (1493.2–6503.0), P = 0.002], and heart rate [80.0 (74.5–90.5) vs. 75.0 (70.3–87.0), P = 0.031] were markedly decreased after treatment with sacubitril-valsartan. Signs and symptoms of heart failure (21/21 vs. 15/21, P = 0.021) were obviously alleviated, NYHA classification and E/e' ratio showed a notable trend of improvement after 3–12 months of follow-up. None of the patients showed adverse drug reactions.Conclusions: The present data suggested that sacubitril-valsartan treatment in patients with HFpEF undergoing PD was effective and safe.

Aims: HFA-PEFF score has been proposed for diagnosing heart failure with preserved ejection fraction (HFpEF). Currently, there are only a limited number of tools for predicting the prognosis. In this study, we evaluated whether the HFA-PEFF score can predict mortality in patients with HFpEF.Methods: This single-center, retrospective observational study enrolled patients diagnosed with HFpEF at the First Affiliated Hospital of Dalian Medical University between January 1, 2015, and April 30, 2018. The subjects were divided according to their HFA-PEFF score into low (0–2 points), intermediate (3–4 points), and high (5–6 points) score groups. The primary outcome was all-cause mortality.Results: A total of 358 patients (mean age: 70.21 ± 8.64 years, 58.1% female) were included. Of these, 63 (17.6%), 156 (43.6%), and 139 (38.8%) were classified into the low, intermediate, and high score groups, respectively. Over a mean follow-up of 26.9 months, 46 patients (12.8%) died. The percentage of patients who died in the low, intermediate, and high score groups were 1 (1.6%), 18 (11.5%), and 27 (19.4%), respectively. A multivariate Cox regression identified HFA-PEFF score as an independent predictor of all-cause mortality [hazard ratio (HR):1.314, 95% CI: 1.013–1.705, P = 0.039]. A Cox analysis demonstrated a significantly higher rate of mortality in the intermediate (HR: 4.912, 95% CI 1.154–20.907, P = 0.031) and high score groups (HR: 5.291, 95% CI: 1.239–22.593, P = 0.024) than the low score group. A receiver operating characteristic (ROC) analysis indicated that the HFA-PEFF score can effectively predict all-cause mortality after adjusting for age and New York Heart Association (NYHA) class [area under the curve (AUC) 0.726, 95% CI 0.651–0.800, P = 0.000]. With an HFA-PEFF score cut-off value of 3.5, the sensitivity and specificity were 78.3 and 54.8%, respectively. The AUC on ROC analysis for the biomarker component of the score was similar to that of the total score.Conclusions: The HFA-PEFF score can be used both to diagnose HFpEF and predict the prognosis. The higher scores are associated with higher all-cause mortality.

Abstract Background and Aims Angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril–valsartan is a landmark drug in heart failure with reduced ejection fraction (HFrEF), however, it remains unclear in patients with heart failure with preserved ejection fraction (HFpEF), especially the data of ARNI treatment on peritoneal dialysis (PD) patients with HFpEF are lacking. The present study was designed to determine the efficacy and safety of sacubitril–valsartan in patients with HFpEF undergoing peritoneal dialysis. Method We assigned end stage renal disease (ESRD)patients, receiving peritoneal dialysis for 3 months, with New York Heart Association (NYHA) class II to IV heart failure, left ventricular ejection fraction ≥ 50%, and elevated level of N-terminal pro–B-type natriuretic peptide (NT-proBNP) to receive sacubitril/valsartan treatment. Patients were regularly followed up after medication treatment. Wilcoxon matched-pair signed-rank (2 samples) tests were applied to investigate the alterations in Clinical and biochemical parameters as the efficacy before and after taking sacubitril–valsartan, and safety was also assessed. Results Twenty-one patients were recruited in this study. Compared with baseline levels, NT-proBNP levels (p=0.002) and heart rate (p=0.031) were markedly decreased after treatment with sacubitril/valsartan, signs and symptoms of heart failure (21/21 versus 15/21, p=0.021) and NYHA classification were notably improved after 3-12 months follow-up. Conclusion The present data suggested that sacubitril/valsartan treatment in the patients with HFpEF undergoing peritoneal dialysis was effective and safe, which is the first study about sacubitril/valsartan treatment for the PD patients with HFpEF, and it may bring the hope for these patients due to no other effective methods at present.

The Impact

Background: Sacubitril/valsartan has been shown to be superior to enalapril in reducing the risks of death and hospitalization for heart failure (HF). However, knowledge of the impact on cardiac performance remains limited. We sought to evaluate the effects of sacubitril/valsartan on clinical, biochemical and echocardiographic parameters in patients with heart failure and reduced ejection fraction (HFrEF). Methods: Sacubitril/valsartan was administered to 205 HFrEF patients. Results: Among 230 patients (mean age 59 ± 10 years, 46% with ischemic heart disease) 205 (89%) completed the study. After a follow-up of 10.49 (2.93 ± 18.44) months, the percentage of patients in New York Heart Association (NYHA) class III changed from 40% to 17% (p < 0.001). Median N–Type natriuretic peptide (Nt-proBNP) decreased from 1865 ± 2318 to 1514 ± 2205 pg/mL, (p = 0.01). Furosemide dose reduced from 131.3 ± 154.5 to 120 ± 142.5 (p = 0.047). Ejection fraction (from 27± 5.9% to 30 ± 7.7% (p < 0.001) and E/A ratio (from 1.67 ± 1.21 to 1.42 ± 1.12 (p = 0.002)) improved. Moderate to severe mitral regurgitation (from 30.1% to 17.4%; p = 0.002) and tricuspid velocity decreased from 2.8 ± 0.55 m/s to 2.64 ± 0.59 m/s (p < 0.014). Conclusions: Sacubitril/valsartan induce “hemodynamic recovery” and, consistently with reduction in Nt-proBNP concentrations, improve NYHA class despite diuretic dose reduction.

INTRODUCTION Only a few cases of biventricular cardiogenic shock have been treated with Impella circulatory assist devices in the United States. CLINICAL FINDINGS A 29-year-old man came to the emergency department because of cough, shortness of breath, fever, and chills. Initial assessment revealed hypotension; an elevated creatinine level of 2.1 mg/dL; and markedly elevated results on liver function tests, with alanine transaminase 5228 IU/L and aspartate aminotransferase 6200 IU/L. The patient’s signs and symptoms met criteria for New York Heart Association class IV heart failure and associated poor prognosis for recovery. DIAGNOSIS Echocardiography revealed dilated cardiomyopathy and biventricular failure with an ejection fraction of 15%. Results of an endomyocardial biopsy confirmed the diagnosis of myocarditis. INTERVENTIONS After unsuccessful treatment with inotropes, biventricular support was started with an Impella CP device in the left ventricle and an Impella RP device in the pulmonary artery. OUTCOMES The patient was maintained on support for 8 days and was discharged to home from the hospital after 27 days. Repeat echocardiography 90 days after discharge indicated improvement in ejection fraction to 40%. At follow-up 16 weeks after discharge, all signs and symptoms of heart failure had resolved. The patient has not had any inpatient readmissions to the hospital to date. CONCLUSION This case presents an opportunity for analysis of care activities and role responsibilities of bedside nurses in caring for this patient. Discussion of this case expands the literature describing nursing activities associated with caring for patients with Impella devices.

Abstract Aims Atrial fibrillation (AF) in patients suffering from heart failure with preserved ejection fraction (HFpEF) is associated with increased symptoms and higher morbidity and mortality. Effective treatment strategies for this patient population have not yet been established. Methods and results We analysed clinical outcomes and echocardiographic parameters of patients with AF and HFpEF who underwent pulmonary vein isolation (PVI). Out of 374 PVI patients, we identified 35 patients suffering from concomitant HFpEF. Freedom from atrial tachyarrhythmia (AT) after 1 year was 80%. Heart failure symptoms assessed by New York Heart Association class significantly improved from 2.7 ± 0.7 to 1.7 ± 0.9 (P &lt; 0.001). We observed regression of diastolic dysfunction by echocardiography 12 months after the index procedure. Moreover, 15 patients (42.9%) experienced complete resolution of HFpEF after a single ablation procedure. Multivariate logistic regression revealed absence of AT recurrence as an independent predictor of recovery from HFpEF (hazard ratio 11.37, 95% confidence interval 1.70–75.84, P = 0.009). Furthermore, resolution of HFpEF by achieving freedom from AT recurrence by PVI, including multiple procedures, led to a significant reduction of hospitalizations. Conclusion Our results suggest that restoration of sinus rhythm by PVI in HFpEF patients with concomitant AF induces reverse remodelling, improvement of symptoms, resolution of HFpEF and subsequently decrease of hospitalizations. Randomized controlled trials are warranted to confirm our results.

ObjectiveNew York Heart Association (NYHA) functional class plays a central role in heart failure (HF) assessment but might be unreliable in mild presentations. We compared objective measures of HF functional evaluation between patients classified as NYHA I and II in the Rede Brasileira de Estudos em Insuficiência Cardíaca (ReBIC)-1 Trial.MethodsThe ReBIC-1 Trial included outpatients with stable HF with reduced ejection fraction. All patients had simultaneous protocol-defined assessment of NYHA class, 6 min walk test (6MWT), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and patient’s self-perception of dyspnoea using a Visual Analogue Scale (VAS, range 0–100).ResultsOf 188 included patients with HF, 122 (65%) were classified as NYHA I and 66 (35%) as NYHA II at baseline. Although NYHA class I patients had lower dyspnoea VAS Scores (median 16 (IQR, 4–30) for class I vs 27.5 (11–49) for class II, p=0.001), overlap between classes was substantial (density overlap=60%). A similar profile was observed for NT-proBNP levels (620 pg/mL (248–1333) vs 778 (421–1737), p=0.015; overlap=78%) and for 6MWT distance (400 m (330–466) vs 351 m (286–408), p=0.028; overlap=64%). Among NYHA class I patients, 19%–34% had one marker of HF severity (VAS Score >30 points, 6MWT <300 m or NT-proBNP levels >1000 pg/mL) and 6%–10% had two of them. Temporal change in functional class was not accompanied by variation on dyspnoea VAS (p=0.14).ConclusionsMost patients classified as NYHA classes I and II had similar self-perception of their limitation, objective physical capabilities and levels of natriuretic peptides. These results suggest the NYHA classification poorly discriminates patients with mild HF.

The Cost

Background: For management of heart failure, the value of the CardioMems device remains uncertain. We assessed the cost-effectiveness of the CardioMems device. Methods: We developed a Markov model to determine quality-adjusted life-years (QALYs), cost, and cost-effectiveness of patients with heart failure receiving CardioMems implantation compared to those with routine care. In the main case analysis, we modeled the intervention in the CHAMPION trial cohort, which included patients with NYHA Class III heart failure with a heart failure hospitalization within the past twelve months. We also performed subgroup analyses of patients with preserved ejection fraction or reduced ejection fraction, and a scenario analysis of a second cohort of patients from the CHARM trials with a previous heart failure hospitalization. We obtained event rates and utilities from published trial data; we used costs from literature estimates and Medicare payment data. The main case analysis was calibrated to the hospitalization and survival rates of the CHAMPION trial. Results: In the CHAMPION trial main case analysis, CardioMems reduced lifetime hospitalizations (2.37 versus 3.27), increased months of survival (67 versus 62), increased QALYs (2.66 versus 2.38) and increased costs ($171,132 versus $154,084), yielding a cost of $59,520 per QALY gained or $40,301 per life-year gained. The cost per QALY gained was $71,964 in patients with reduced ejection fraction compared to $34,899 in those with preserved ejection fraction. In less ill patients from the CHARM trials, which included patients with NYHA Class II heart failure, the device cost increased to $110,565 per QALY gained. If the device cost decreased from $17,500 in the main case analysis to $15,000, the intervention would cost less than $50,000 per QALY gained. The duration of effectiveness was initially assumed to be lifelong; if less than 29 months, CardioMems would cost more than $150,000 per QALY gained. Conclusion: The CardioMems device is cost-effective in populations similar to the CHAMPION trial, with a cost of less than $100,000 per QALY gained, if durability of device effectiveness is sustained. Post-marketing surveillance data on the device’s durability will further clarify its value.

Reported Health

Background: A foundation of current clinical trials is to categorize the severity of heart failure (HF) by New York Heart Association (NYHA) classification to ensure that enrolled patients have similar disease severity. Because the NYHA represents a clinician’s assessment of patients’ health status, it may vary from patients’ perspectives and can lead to more or less symptomatic patients being enrolled in clinical trials. We sought to directly compare the ranges of patient-reported health status, as assessed by the well-validated and reliable Kansas City Cardiomyopathy Questionnaire (KCCQ), with NYHA class in recent clinical studies. Methods: We used data from 2 contemporary HF clinical trials, HF-ACTION in patients with Heart Failure with Reduced Ejection Fraction (HFrEF) and TOPCAT in patients with Heart Failure with Preserved Ejection Fraction (HFpEF), and 1 prospective cohort study, the KCCQ Interpretability study (KCCQINT) in patients with HFrEF, where both NYHA and the KCCQ were contemporaneously collected. The distributions of KCCQ Overall Summary (KCCQ-os) scores by NYHA and the variation in assigned NYHA classes among patients with KCCQ scores ≥80 (congruent with NYHA Class I) were then described. Results: A total of 6,072 patients (mean age 64±12 years, 41% female) were included across the 3 studies. Figure 1 shows marked overlap in KCCQ scores across NYHA classes. In KCCQINT, 148 (27%) out of 545 patients reported a KCCQ-os score ≥80, of whom 39 (26%), 81 (55%) and 28 (19%) were coded as NYHA Class I, II and III. None were classified as NYHA Class IV. In HF-ACTION, 677 (32%) of 2129 patients reported a KCCQ-os score ≥80, of whom 548 (81%), 128 (19%) and 1 (<1%) were coded as NYHA Class II, III and IV, respectively. In TOPCAT, 484 (14%) out of 3398 patients reported a KCCQ-os score ≥80, of whom 410 (85%) and 74 (15%) were considered NYHA Class I-II and III-IV, respectively. Conclusions: Although the NYHA is used to identify similarly ill patients for enrollment in clinical trials, there is marked variability within and across studies in patients’ self-reported health status. Future trials should consider patient-reported outcome measures as the basis for defining patient eligibility to enroll a more homogenous cohort of disease severity.

Neprilysin Inhibitor

The mechanisms for the benefits of Angiotensin Receptor Neprilysin inhibitor (ARNi) in heart failure patients with reduced ejection fraction (HFrEF) are likely beyond blood pressure (BP) reduction. Vascular function, a prognostic marker in HFrEF, improves with ARNi in animal models. Improvements in vascular function may contribute to benefits from ARNi in HFrEF; however, this has yet to be demonstrated in humans. The purpose of the study was to test the hypothesis that arterial stiffness and endothelial function would improve after 12 weeks of ARNi in HFrEF. Methods: HFrEF participants with NYHA class II-III were enrolled from local cardiology clinics and completed experimental visits at baseline and 12 weeks later: 13 participants were prescribed ARNi by their cardiologist [62±10 years, Men: 10, BMI: 30±5 kg/m 2 , EF: 28±6 %; Non-ischemic cardiomyopathy (NICM): 8], 10 participants continued on conventional treatment [CON: 60±7 years, Men: 6, BMI: 31±6 kg/m 2 , EF: 31±5 % and NICM: 4; all P=NS]. During each experimental visit, arterial stiffness was assessed via carotid-femoral pulse wave velocity (PWV; Sphygmocor PVx system) and endothelial function by brachial artery flow-mediated dilation (FMD) using standard techniques. Statistical analyses were performed using 2x2 repeated-measures ANOVA. Results: Baseline mean BP (MAP) was similar between ARNi (93±14 mmHg) and CON (85 ± 10 mmHg; P=0.13); MAP tended to decrease after 12 weeks of ARNi (88 ± 11 mmHg; P=0.08) but not CON (90 ± 17 mmHg; P=0.14) (ANOVA interaction P=0.03). PWV tended to be higher at baseline in ARNi (8.8 ± 2.5 m/s) compared to CON (7.0 ± 2.5 m/s; P=0.09); PWV decreased after 12 weeks of ARNi (7.0 ± 1.7 m/s; P<0.01) and was unchanged in CON (7.4 ± 2.4 m/s; P=0.33) (ANOVA interaction P<0.01). When controlling for MAP, the effect of ARNi on PWV remained (P<0.01). At baseline, FMD was similar between ARNi (2.81 ± 2.05%) and CON (4.75 ± 3.75%; P=0.13); however, FMD increased after 12 weeks of ARNi (5.73 ± 1.87%; P<0.001) but not in CON (5.37 ± 3.38%; P=0.33) (ANOVA time P<0.001, interaction P=0.01). Conclusion: ARNi improves arterial stiffness and endothelial function in HFrEF. Understanding the mechanisms of ARNi in HFrEF is crucial as it may pave the way for better interventions in other cardiovascular diseases.
