sacubitril and Heart-Failure--Systolic

This study investigates the effect of sacubitril/valsartan (Sac/Val) in patients diagnosed with nonvalvular atrial fibrillation (AF) without systolic heart failure (SHF).Nonvalvular AF patients without SHF admitted to the People's Hospital of Bortala Mongol Autonomous Prefecture from December 2020 to December 2021 were enrolled and randomly divided into Sac/Val treatment group (group T) and valsartan treatment group (group C, control). For subgroup analysis, patients were divided into subgroups with and without diastolic heart failure (DHF). After 1-month adaptive phase and subsequent 3-month treatment period, patients were followed up in the cardiology clinic. Plasma levels of biochemical markers and echocardiographic parameters before and after treatment were evaluated, and DHF scores were computed to assess diastolic function.Of 61 enrolled patients, 46 patients completed follow-up. Sac/Val treatment did not increase the percentage of sinus rhythm. Although N-terminal pro-B-type natriuretic peptide (NT-proBNP) expression tended to be reduced in both groups after 3 months of treatment, the differences compared with respective baseline levels and between groups were not significant. According to subgroup analysis, although NT-proBNP expression in the subgroup with DHF was lower at follow-up compared to baseline, the difference was not statistically significant. Similarly, no marked differences in echocardiographic parameters or tissue Doppler parameters related to DHF were detected between the groups (P > 0.05). Additionally, a subgroup analysis found no significant variations in the echocardiographic measures (P > 0.05).Sac/Val is not superior to valsartan for the short-term treatment of patients suffering with AF without SHF in improving NT-proBNP level and cardiac function.

Pharmacists' care in heart failure (HF) management has been shown to better clinical outcomes, including use of guideline-directed medical therapy and hospital readmission, although the impact observed has varied among studies.. To investigate the rates of all-cause hospitalization and hospitalization from HF (hHF) and changes in surrogate markers (left-ventricular ejection fraction, New York Heart Association Functional Classification [NYHA FC], diuretic requirements) for patients with HF with reduced ejection fraction (HFrEF) on angiotensin receptor-neprilysin inhibitor (ARNi) therapy optimized within a pharmacist clinic.. Retrospective chart review of patients with HFrEF on sacubitril/valsartan from July 7, 2015, through January 1, 2018.. For the primary outcome analysis, 70 patients with pre/post hospitalization data had a reduction in the rate of all-cause hospitalization from 45.7% in the 12 months prior to ARNi therapy initiation to 24.3% during the first year on optimized ARNi therapy (. Real-world use of sacubitril/valsartan optimized within a pharmacist clinic was associated with reduced prevalence of all-cause and hHF during the first year of ARNi therapy. This study corroborates pharmacist involvement in HF management, which could be used to support further research and expanded pharmacist services.

Heart failure with reduced ejection fraction (HFrEF) is a heterogeneous syndrome. In heart failure (HF) classifications, right ventricle (RV) function was for a long time unrecognized in favor of left ventricular ejection fraction (LVEF). The response to sacubitril/valsartan might differ according to phenotypes and the impact of right ventricular characteristics on this response remains controversial.. First, we applied clustering analysis in a HFrEF population undergoing sacubitril/valsartan treatment according to guidelines, to identify phenotypes and their associated clinical outcomes. Secondly, we evaluated RV-remodeling.. It is a prospective, observational, single-center study conducted on 108 symptomatic patients (mean age 66 ±12.8 years, 22.2% women). First, the clustering analysis was applied in a HFrEF population undergoing sacubitril/valsartan treatment, according to the guidelines, in order to identify phenotypes and clinical outcomes associated with them. Secondly, we evaluated RV-remodeling.. Two distinct clusters were identified. Among the differences between phenotypes, RV (tricuspid annular plane systolic excursion (TAPSE) 16 ±4 mm compared to 19 ±4 mm, p < 0.001; RV free wall strain -19 ±5% compared to -21 ±4%, p = 0.046; RV fraction area change (FAC) 31 ±9% compared to 38 ±9%, p < 0.001), LV-filling pressure (E-wave deceleration time 138 (median: 41) ms compared to 180 (median: 94) ms, p < 0.001; E/e' 16.7 (median: 8.0) ms compared to 13.0 (median: 9.7) ms, p = 0.02) and creatinine level (106 ±34 μmol/L compared to 90 ±19 μmol/L, p = 0.002) were substantially different at the initiation of therapy. Major adverse cardiac events (MACEs) or death occurred in 38 out of 107 patients: 51.1% in cluster 1 compared to 24.2% in cluster 2 (p = 0.0074). A significant improvement in RV-functional parameters was observed under treatment. The TAPSE improved and correlated with the change in left ventricular (LV) function. Yet, it did not correlate with systolic pulmonary artery pressure (sPAP) and LV end-diastolic diameter.. The HFrEF phenotype characterized by more severe RV dysfunction has a worse prognosis during sacubitril/valsartan therapy. Both RVand LV functions significantly improve when the patient is treated with sacubitril/valsartan.

Cancer patients are at an increased risk of cardiovascular events. Both old-generation cytostatics/cytotoxics and new-generation "targeted" drugs can in fact damage cardiomyocytes, endothelial cells of veins and arteries, specialized cells of the conduction system, pericardium, and valves. A new discipline, cardio-oncology, has therefore developed with the aim of protecting cancer patients from cardiovascular events, while also providing them with the best possible oncologic treatment. Anthracyclines have long been known to elicit cardiotoxicity that, depending on treatment- or patient-related factors, may progress with a variable velocity toward cardiomyopathy and systolic heart failure. However, early compromise of diastolic function may precede systolic dysfunction, and a progression of early diastolic dysfunction to diastolic rather than systolic heart failure has been documented in long-term cancer survivors. This chapter first describes general notions about hypertension in the cancer patient and then moves on reviewing the pathophysiology and clinical trajectories of diastolic dysfunction, and the molecular mechanisms of anthracycline-induced diastolic dysfunction. Diastolic dysfunction can in fact be caused and/or aggravated by hypertension. Pharmacologic foundations and therapeutic opportunities to prevent or treat diastolic dysfunction before it progresses toward heart failure are also reviewed, with a special emphasis on the mechanisms of action of drugs that raised hopes to treat diastolic dysfunction in the general population (sacubitril/valsartan, guanylyl cyclase activators, phosphodiesterase inhibitors, ranolazine, inhibitors of type-2 sodium-glucose-inked transporter). Cardio-oncologists will be confronted with the risk:benefit ratio of using these drugs in the cancer patient.
