Aim: We evaluated the influence of sacubitril/valsartan on the left ventricle function and clinical status of patients with heart failure and a reduced ejection fraction. Materials and methods: From 2018 to 2020, patients cured with 50-200 mg sacubitril/valsartan after coronary bypass grafting or coronary stenting for ischemic heart disease and HFrEF (aged 54-70 years) were enrolled in this prospective study. Results: There was no death case. There was a female prevalence with female to male ratio of 1,7:1. the value of ejection fraction high significantly increased (p=0,035), whereas the indices of left ventricle end-diastolic volume (p=0,015) and end-diastolic volume index (p=0,022) as well as left ventricle mass index were high significantly decreased (p=0,001) that indicate the amelioration of left ventricle systolic function. Correspondingly, the clinical status of all patients improved according to New York Heart Association Class (p=0,001). Conclusion: The post-CABG or PCI patients with HFrEF should be cured with sacubitril/valsartan basing on its implementation instruction. Nevertheless, future studies should focus on a larger cohort of post-CABG or PCI patients to compare the effectiveness and safety of sacubitril/valsartan usage raising from its adverse event in comparison to conventional therapy.

Patients With Heart Failure

During these more than 20 years of evolution in understandings of the mechanisms of heart failure (HF) with preserved fractional ejection, there has been a rich variety of terminology, including „diastolic heart failure“, „heart failure with preserved systolic function“ and „heart failure with preserved fraction“. By defi nition, the latter term “ejection fraction-induced heart failure” proved to be the most appropriate and was accepted as the most correct, as the presence of diastolic dysfunction is not unique only to this group and exists in these patients, albeit subclinically and discrete disturbance in the longitudinal systolic function of the left ventricle against the background of the preserved ejection fraction. The problem, however, is not in the value of the ejection fraction or in the paradox of the combination of a well-functioning left ventricle and classic symptoms of heart failure, but in the non-infl uence of the prognosis of these patients in the way it is in patients with suppressed EF. Unlike patients with heart failure with a reduced ejection fraction, the prognosis and results in patients with HF with preserved EF do not mark the expected results and so far there are not enough effective and promising therapies.

Echocardiographic Parameters

Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test <0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p<0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p<0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p<0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

ObjectivesThe severity of diastolic dysfunction is assessed using a combination of several indices of left atrial (LA) volume overload and LA pressure overload. We aimed to clarify which overload is more associated with the prognosis in patients with heart failure and preserved ejection fraction (HFpEF).SettingA prospective, multicenter observational registry of collaborating hospitals in Osaka, Japan.ParticipantsWe enrolled hospitalised patients with HFpEF showing sinus rhythm (men, 79; women, 113). Blood tests and transthoracic echocardiography were performed before discharge. The ratio of diastolic elastance (Ed) to arterial elastance (Ea) was used as a relative index of LA pressure overload.Primary outcome measuresAll-cause mortality and admission for heart failure were evaluated at >1 year after discharge.ResultsIn the multivariable Cox regression analysis, Ed/Ea, but not LA volume index, was significantly associated with all-cause mortality or admission for heart failure (HR 2.034, 95% CI 1.059 to 3.907, p=0.032), independent of age, sex, and the serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level. In patients with a higher NT-proBNP level, the effect of higher Ed/Ea on prognosis was prominent (p=0.015).ConclusionsEd/Ea, an index of LA pressure overload, was significantly associated with the prognosis in elderly patients with HFpEF showing sinus rhythm.Trial registration numberUMIN000021831.

Abstract Background The guidelines recommend to determine natriuretic peptides, clinical status (NYHA classification) and comorbidities in order to predict the prognosis in patients with heart failure. The aim ofthis registry was to develop a prognostic score in chronic heart failure patients, using clinical status, comorbidities and natriuretic peptides. Methods Consecutive 1088 patients with stable chronic heart failure with reduced ejection fraction (HFrEF) (LVEF<40%) and mid-range EF (HFmrEF) (LVEF 40–49%) were enrolled. Two-year all-cause mortality, heart transplantation and/or LVAD implantation were defined as the primary endpoint (MACE). Results The occurrence of MACE was 14.9% and increased with higher NYHA, 4.9% (NYHA I), 11.4% (NYHA II) and 27.8% (NYHA III-IV) (p<0.001). The occurrence of MACE was 3%, 10% and 15–37% in patients with NT-proBNP levels ≤125pg/ml, 126–1000pg/ml and >1000pg/ml respectively. Discrimination abilities of NYHA and NT-proBNP were (AUC 0.670; p<0.001 and AUC 0.722; p<0.001). The predictive value of the developed clinical model, which took account of older age, advanced heart failure (NYHA III+IV), anaemia, hyponatraemia, hyperuricaemia and taking a higher dose of loop diuretics (>40 mg furosemide daily) (AUC 0.773; p<0.001) was increased by adding the NT-proBNP level (AUC 0.790). Conclusion Natriuretic peptides, clinical status and comorbiditis predict two year prognosis and they can help to a better identification of a high-risk groups of patients with heart failure with reduced and mid range ejection fraction in which more intense treatment should be considered, mainly LVAD implantation or listing to heart transplantation waiting list.
