The Difference

Aims: Patients with heart failure (HF) exhibit ventricular dyssynchrony with negative effects on ventricular systolic and diastolic performance and poor prognosis. There is no consensus about the best approach for estimating the dyssynchrony and for selecting candidates for resynchronization therapy (CRT). We sought to evaluate whether Myocardial Performance Index (MPI), calculated as differences between left and right ventricle (LV, RV), ∆MPI, represents a marker of interventricular dyssynchrony. Methods: The study included 40 patients (22 males, 18 females, mean age 71±13) with NYHA functional class II-III, chronic heart failure (77% ischaemic), in optimal drug therapy for at least three months. All patients underwent a complete two-dimensional and Tissue Doppler Echocardiography (TDE), including an assessment of MPI in both ventricles. Results: Significant correlations were found between ∆MPI and QRS (r = 0.41, p < 0.001), with NYHA (r = 0.66, p < 0.001), with SPWMD (r = 0.32, p < 0.05), with LV ejection fraction (r = -0.32, p < 0.05), with Spv wave at the septal site of LV (r = -0.32, p < 0.05), and with IVMD (r = 0.44, p < 0.001). Ten patients have been re-evaluated six months after CRT implantation, and ∆MPI significantly correlated with the difference between basal LVEF and six months after CRT implantation (r = 0.43, p < 0.04). Conclusion: The ∆MPI could represent an integrative marker of interventricular dyssynchrony and could be considered as a new parameter in the patient selection process to be undergone CRT.

Background. Morbidity and mortality in patients with functional mitral regurgitation (FMR) remains high, however, no pharmacological therapy has been proven to be effective.Aimsto study the effect of sacubitrile/valsartan and valsartan on functional mitral regurgitation in chronic heart failure.Methods.This double-blind study randomly assigned sacubitrile/valsartan or valsartan in addition to standard drug therapy for heart failure among 100 patients with heart failure with chronic FMR (secondary to left ventricular (LV) dysfunction). The primary endpoint was a change in the effective area of the regurgitation hole during the 12-month follow-up. Secondary endpoints included changes in the volume of regurgitation, the final systolic volume of the left ventricle, the final diastolic volume of the left ventricle, and the area of incomplete closure of the mitral valves.Results.The decrease in the effective area of the regurgitation hole was significantly more pronounced in the sacubitrile/valsartan group than in the valsartan group (0.070.066against0.030.058sm2; p=0.018)in the treatment efficacy analysis, which included 100patients (100%). The regurgitation volume also significantly decreased in the sacubitrile/valsartan group compared to the valsartan group (mean difference:8.4ml; 95%CI, from 13.2 until 1.9;р=0.21). There were no significant differences between the groups regarding changes in the area ofincomplete closure of the mitral valves and LV volumes, with the exception of the index of the final LV diastolic volume (p=0.07).Conclusion.Among patients with secondary FMR, sacubitril/valsartan reduced MR more than valsartan. Thus, angiotensin receptor inhibitors and neprilysin can be considered for optimal drug treatment of patients with heart failure and FMR.

Background: Patients with heart failure (HF) have notably poor health-related quality of life (HRQOL), which is associated with high hospitalization rates. Physical symptoms have been associated with poor HRQOL. However, whether improvement in physical symptoms actually leads to improvement in HRQOL has not fully examined in patients with HF. Purpose: To examine the effects of changes in physical symptoms on changes in HRQOL at 12 months, after controlling for age, comorbidities, New York Heart Association (NYHA) functional class, and modifiable psychosocial and behavioral factors. Methods: Data on physical symptoms (Symptom Status Questionnaire-HF) and HRQOL (Minnesota Living with Heart Failure) were collected from 94 patients with HF (mean age 58 ± 14 years, 44% male, 58% NYHA functional class II/III) at baseline and 12 month follow-up. Age, comorbidities, and NYHA functional class were collected using standard questionnaires at baseline. Psychosocial variables (depressive symptoms [Patient Health Questionnaire], perceived control [Control Attitudes Scale-Revised], and social support [Multidimensional Scale of Perceived Social Support]) and behavioral variables (medication adherence [Micro-Electro-Mechanical Systems], sodium intake [24-hour urine], and self-care management [Self-care management subscale of the Self-Care of Heart Failure Index]) were collected at baseline. Hierarchical multiple regression analyses were used to analyze the data. Results: The mean score changes in physical symptoms and HRQOL were -3.8 (± 14.1) and -9.2 (± 24.1), respectively (negative scores indicate improvement.). Among the sociodemographic and clinical characteristics, psychosocial variables, behavioral variables, baseline physical symptoms, and changes in physical symptoms, only changes in physical symptoms predicted changes in HRQOL at 12 months (F = 6.384, R2 = .46, p < .001). Improvement in physical symptoms led to improvement in HRQOL. Conclusion: It is critical to improve physical symptoms to improve HRQOL. Thus, development and delivery of effective interventions targeting improvement in physical symptoms are warranted in this population.

Introduction: Malnutrition is a factor that defines vital prognosis in chronic heart failure. Objective: This study investigated nutritional and metabolic disorders in patients with heart failure by examining the association of severity of heart failure with inflammatory cytokines, appetite-regulating hormones, and energy metabolism. Methods: Subjects were 50 patients with heart failure. On admission, nutritional status was assessed, and biochemical blood tests were performed, including for serum tumor necrosis factor-α, interleukin-6, ghrelin, and leptin levels. Resting energy expenditure (REE) was also measured by indirect calorimetry to examine its association with severity of heart failure and levels of inflammatory cytokines and appetite-regulating hormones. Results: There were significant associations between serum brain natriuretic peptide (BNP) level and nutrition indices, indicating that nutritional status was worse when heart failure was more severe. Inflammatory cytokine levels showed significant positive correlations with BNP level. Measured REE/bodyweight was not associated with severity of heart failure, but was negatively correlated with body fat percentage and leptin levels. Conclusions: Energy metabolism was not associated with serum BNP level among patients with heart failure with New York Heart Association functional class up to III. Body fat percentage and leptin levels may be a good predictor of energy metabolism in patients with heart failure.
