The Impact

Objectives: In the Systolic Heart Failure Treatment with the If Inhibitor Ivabradine Trial (SHIFT), slowing of the heart rate with ivabradine reduced cardiovascular death or heart failure hospitalizations among patients with systolic chronic heart failure (CHF). Subsequently, in the Study Assessing the Morbidity-Mortality Benefits of the If Inhibitor Ivabradine in Patients with Coronary Artery Disease (SIGNIFY) slowing of the heart rate in patients without CHF provided no benefit for cardiovascular death or nonfatal myocardial infarction (primary composite end point), with secondary analyses suggesting possible harm in the angina subgroup. Therefore, we examined the impact of ivabradine in the patients with CHF plus angina in SHIFT. Methods: SHIFT enrolled adults with stable, symptomatic CHF, a left ventricular ejection fraction ≤35% and a sinus rhythm with a resting heart rate ≥70 bpm. Outcomes were the SHIFT and SIGNIFY primary composite end points and their components. Results: Of 6,505 patients in SHIFT, 2,220 (34%) reported angina at randomization. Ivabradine numerically, but not significantly, reduced the SIGNIFY primary composite end point by 8, 11 and 11% in the SHIFT angina subgroup, nonangina subgroup and overall population, respectively. Ivabradine also reduced the SHIFT primary composite end point in all 3 subgroups. Conclusions: In SHIFT, ivabradine showed consistent reduction of cardiovascular outcomes in patients with CHF; similar results were seen in the subgroup of SHIFT patients with angina.

The Impact

Psychological stress is a well-established risk factor for cardiovascular disease (CVD). Heart rate variability (HRV)-biofeedback could significantly reduce stress levels and improve autonomic nervous system function and cardiovascular endpoints. We aimed to systematically review the literature to investigate the impact of HRV modulation through HRV-biofeedback on clinical outcomes in patients with CVD. A literature search was performed in the following databases: MEDLINE (PubMed), Embase, and Cochrane from the inception until 1 October 2021. Patients in the HRV-biofeedback group had significantly lower rates of all-cause readmissions than patients who received psychological education (respectively, p = 0.028 and p = 0.001). Heart failure following HRV-biofeedback displayed an inverse association with stress and depression (respectively, p = 0.022 and p = 0.033). When stratified according to left ventricular ejection fraction (LVEF), patients with LVEF ≥ 31% showed improved values of the 6 min walk test after HRV-biofeedback interventions (p = 0.05). A reduction in systolic and diastolic blood pressure associated with HRV-biofeedback was observed (p < 0.01) in pre-hypertensive patients. HRV-biofeedback had beneficial effects on different cardiovascular diseases documented in clinical trials, such as arterial hypertension, heart failure, and coronary artery disease. A standard breathing protocol should be applied in future studies to obtain equivalent results and outcomes. However, data regarding mortality in patients with coronary artery disease are scarce and need further research.

Resynchronisation Therapy

Cardiac resynchronisation therapy (CRT) is an efficacious and cost-effective therapy in patients with highly symptomatic systolic heart failure and delayed ventricular conduction. Current guidelines recommend CRT as a class I indication for patients with sinus rhythm, New York Heart Association (NYHA) functional class III or ambulatory class IV, a QRS duration ≥120ms, and left ventricular ejection fraction (LVEF) ≤35%, despite optimal pharmacological therapy. Recent trials resulted in an extension of current recommendations to patients with mild heart failure, patients with atrial fibrillation, and patients with an indication for permanent right ventricular pacing with the aim of morbidity reduction. The effectiveness of CRT in patients with narrow QRS, patients with end-stage heart failure and cardiogenic shock, and patients with an LVEF >35% still needs to be proved. This article reviews current evidence and clinical applications of CRT in heart failure and provides an outlook on future developments.

Background: The prognostic importance of right ventricular (RV) dysfunction has been suggested in patients with systolic heart failure (due to primary or secondary dilated cardiomyopathy - DCM). Tricuspid annular plane systolic excursion (TAPSE) is a simple, feasible, reality, non-invasive measurement by transthoracic echocardiography for evaluating RV systolic function. Objectives: To evaluate TAPSE in patients with primary or secondary DCM who have left ventricular ejection fraction ≤ 40% and to find the relation between TAPSE and LVEF, LVDd, RVDd, RVDd/LVDd, RA size, severity of TR and PAPs. Materials and Methods: 61 patients (36 males, 59%) mean age 58.6 ± 14.4 years old with clinical signs and symtomps of chronic heart failure which caused by primary or secondary DCM and LVEF ≤ 40% and 30 healthy subject (15 males, 50%) mean age 57.1 ± 16.8 were included in this study. All patients and controls were underwent echocardiographic examination by M-mode, two dimentional, convensional Dopler and TAPSE. Results: TAPSE is significant low in patients compare with the controls (13.93±2.78 mm vs 23.57± 1.60mm, p<0.001). TAPSE is linearly positive correlate with echocardiographic left ventricular ejection fraction (r= 0,43; p<0,001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation was found with LVDd and PAPs. Conclusions: 1. Decreased RV systolic function as estimated by TAPSE in patients with systolic heart failure primary and secondary DCM) compare with controls. 2. TAPSE is linearly positive correlate with LVEF (r= 0.43; p<0.001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation is found with LVDd and PAPs. 3. TAPSE should be used routinely as a simple, feasible, reality method of estimating RV function in the patients systolic heart failure DCM (primary and secondary).

Abstract Background Heart failure (HF) is a major and growing medical and economic problem, with high prevalence and incidence rates worldwide. Cardiac Biomarker is emerging as a novel tool for improving management of patients with HF with a reduced left ventricular ejection fraction (HFrEF). Methods This is a before and after interventional study, that assesses the impact of a personalized follow-up procedure for HF on patient’s outcomes and care associated cost, based on a clinical model of risk stratification and personalized management according to that risk. A total of 192 patients were enrolled and studied before the intervention and again after the intervention. The primary objective was the rate of readmissions, due to a HF. Secondary outcome compared the rate of ED visits and quality of life improvement assessed by the number of patients who had reduced NYHA score. A cost-analysis was also performed on these data. Results Admission rates significantly decreased by 19.8% after the intervention (from 30.2 to 10.4), the total hospital admissions were reduced by 32 (from 78 to 46) and the total length of stay was reduced by 7 days (from 15 to 9 days). The rate of ED visits was reduced by 44% (from 64 to 20). Thirty-one percent of patients had an improved functional class score after the intervention, whereas only 7.8% got worse. The overall cost saving associated with the intervention was € 72,769 per patient (from € 201,189 to € 128,420) and €139,717.65 for the whole group over 1 year. Conclusions A personalized follow-up of HF patients led to important outcome benefits and resulted in cost savings, mainly due to the reduction of patient hospitalization readmissions and a significant reduction of care-associated costs, suggesting that greater attention should be given to this high-risk cohort to minimize the risk of hospitalization readmissions.

In the failing human myocardium, both impaired calcium homoeostasis and alterations in the levels of contractile proteins have been observed, which may be responsible for reduced contractility as well as diastolic dysfunction. In addition, levels of a key protein in calcium cycling, i.e. the sarcoplasmic reticulum Ca2+-ATPase, and of the α-myosin heavy chain have been shown to be enhanced by treatment with etomoxir, a carnitine palmitoyltransferase inhibitor, in normal and pressure-overloaded rat myocardium. We therefore studied, for the first time, the influence of long-term oral application of etomoxir on cardiac function in patients with chronic heart failure. A dose of 80 mg of etomoxir was given once daily to 10 patients suffering from heart failure (NYHA functional class II–III; mean age 55±4 years; one patient with ischaemic heart disease and nine patients with dilated idiopathic cardiomyopathy; all male), in addition to standard therapy. The left ventricular ejection fraction was measured echocardiographically before and after a 3-month period of treatment. Central haemodynamics at rest and exercise (supine position bicycle) were defined by means of a pulmonary artery catheter and thermodilution. All 10 patients improved clinically; no patient had to stop taking the study medication because of side effects; and no patient died during the 3-month period. Maximum cardiac output during exercise increased from 9.72±1.25 l/min before to 13.44±1.50 l/min after treatment (P < 0.01); this increase was mainly due to an increased stroke volume [84±7 ml before and 109±9 ml after treatment (P < 0.01)]. Resting heart rate was slightly reduced (not statistically significant). During exercise, for any given heart rate, stroke volume was significantly enhanced (P < 0.05). The left ventricular ejection fraction increased significantly from 21.5±2.6% to 27.0±2.3% (P < 0.01). In acute studies, etomoxir showed neither a positive inotropic effect nor vasodilatory properties. Thus, although the results of this small pilot study are not placebo-controlled, all patients seem to have benefitted from etomoxir treatment. Etomoxir, which has no acute inotropic or vasodilatory properties and is thought to increase gene expression of the sarcoplasmic reticulum Ca2+-ATPase and the α-myosin heavy chain, improved clinical status, central haemodynamics at rest and during exercise, and left ventricular ejection fraction.

Mode Of Death

Background: Patients with heart failure (HF) and preserved left ventricular ejection fraction comprise a heterogeneous group including some with mildly reduced EF. We hypothesized that mode of death differs by EF in ambulatory patients with HF and preserved left ventricular ejection fraction. Methods: PARAGON-HF trial (Prospective Comparison of Angiotensin Receptor–Neprilysin Inhibitor With Angiotensin-Receptor Blocker Global Outcomes in Heart Failure With Preserved Ejection Fraction) compared clinical outcomes in 4796 patients with chronic HF and EF ≥45% randomly assigned to sacubitril/valsartan or valsartan. We examined the mode of death in relation to baseline EF in logistic regression models and the effect of randomized treatment on cause-specific death in Cox regression models. Nonlinear relationships with continuous EF were modelled using quadratic and cubic terms. Results: Of 691 deaths during the trial, 416 (60%) were ascribed to cardiovascular, 220 (32%) to noncardiovascular, and 55 (8%) to unknown causes. Of cardiovascular deaths, 154 (37%) were due to sudden death, 118 (28%) were due to HF, 35 (8%) to stroke, 27 (6%) to myocardial infarction, and 82 (20%) to other cardiovascular causes. Rates of all-cause, cardiovascular, and sudden death were higher in those with lower left ventricular ejection fraction (all P <0.001), while rates of non-cardiovascular death were greater in patients with higher EF. Sacubitril/valsartan did not reduce overall death, cardiovascular death, or sudden death compared with valsartan, irrespective of baseline EF (all P for interaction >0.30). Conclusions: Among patients with HF and preserved left ventricular ejection fraction enrolled in PARAGON-HF, the proportion of cardiovascular and sudden death were higher in those with lower left ventricular EF, and the proportion of noncardiovascular death rose with EF. Regardless of EF, sacubitril/valsartan did not reduce death from any cause compared with valsartan. REGISTRATION: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT01920711.

Patients With Heart Failure

The up-date of ESC Guidelines on the management of patients with heart failure was published last year. The beneficial effect of a new group of drugs (flozins, sacubitril/valsartan - ARNI) in patients with heart failure was pointed out. These drugs not only prevent the onset of heart failure but also reduce HF hospitalization rate and in patients with reduced left ventricular ejection fraction decrease risk of cardiovascular death and in case of empagliflozin, dapagliflozin or sacubitril/valsartan also total mortality. These latter medicines reduce also the likelihood of sudden cardiac death. ARNI reduce the number of appropriate ICD shocks, the incidence of non-sustained VT, premature ventricular contractions, and increase percentage of biventricular pacing in car­diac resynchronization recipients.

Abstract Objective: Micro- and macrovascular changes can occur in heart failure, and could influence its prognosis and management. In a prospective study, we proposed the evaluation of arterial stiffness (macrovascular function) and its correlations in patients with systolic heart failure. Methods: 40 patients (32 men, 8 women, mean age 63±2.9 years), with hemodynamically stable systolic heart failure (left ventricular ejection fraction, EF<40%) were enrolled in the study. In every patient, beyond routine explorations (ECG, cardiac and carotid ultrasound, laboratory measurements), arterial stiffness was assessed by measuring pulse wave velocity (PWV). The correlations of PWV with clinical and echo-cardiographic characteristics were studied using t-test and chi-square test (p<0.05 being considered for statistical significance). Results: The average PWV was 8.55±2.2 m/s, and 16 patients had increased PWV (>10 m/s). We found significantly higher PWV values in patients older than 65 years (p<0.001), in patients with eGFR <60 ml/min/1.73 m2 (p<0.001), hypertension (p=0.006), and increased (>1 mm) carotid intima-media thickness (p=0.016). PWV was found to be significantly lower when EF was <30% (p=0.049). Furthermore, the presence of an increased PWV was correlated significantly with age (p<0.001), and (with borderline significance) with eGFR <60 ml/min/1.73 m2 and, inversely, with EF<30%. Conclusions: Increased arterial stiffness reflected by high PWV is frequently present in patients with systolic heart failure, and is mainly correlated with general risk factors of arterial involvement. Low EF, due to low stroke volume and decreased systolic arterial wall tension can influence the values and the interpretation of PWV.

Background: The angiotensin receptor-neprilysin inhibitor (ARNI) decreases cardiovascular mortality in patients with chronic heart failure with a reduced ejection fraction (HFrEF). Data regarding the impact of ARNI on the outcome in HFrEF patients according to heart failure etiology are limited. Methods and results: One hundred twenty-one consecutive patients with HFrEF from the years 2016 to 2017 were included at the Medical Centre Mannheim Heidelberg University and treated with ARNI according to the current guidelines. Left ventricular ejection fraction (LVEF) was numerically improved during the treatment with ARNI in both patient groups, that with ischemic cardiomyopathy (n = 61) (ICMP), and that with non-ischemic cardiomyopathy (n = 60) (NICMP); p = 0.25. Consistent with this data, the NT-proBNP decreased in both groups, more commonly in the NICMP patient group. In addition, the glomerular filtration rate (GFR) and creatinine changed before and after the treatment with ARNI in both groups. In a one-year follow-up, the rate of ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) tended to be higher in the ICMP group compared with the NICMP group (ICMP 38.71% vs. NICMP 17.24%; p = 0.07). The rate of one-year all-cause mortality was similar in both groups (ICMP 6.5% vs. NICMP 6.6%; log-rank = 0.9947). Conclusions: This study shows that, although the treatment with ARNI improves the LVEF in ICMP and NICMP patients, the risk of ventricular tachyarrhythmias remains higher in ICMP patients in comparison with NICMP patients. Renal function is improved in the NICMP group after the treatment. Long-term mortality is similar over a one-year follow-up.
