AI Based CMR Assessment of Biventricular Function: Clinical Significance of Intervendor Variability and Measurement Errors. JACC Cardiovasc Imaging 2022; 15:413-427. [PMID: 34656471 PMCID: PMC8917993 DOI: 10.1016/j.jcmg.2021.08.011] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 08/09/2021] [Accepted: 08/17/2021] [Indexed: 12/30/2022]
Abstract
OBJECTIVES The aim of this study was to determine whether left ventricular ejection fraction (LVEF) and right ventricular ejection fraction (RVEF) and left ventricular mass (LVM) measurements made using 3 fully automated deep learning (DL) algorithms are accurate and interchangeable and can be used to classify ventricular function and risk-stratify patients as accurately as an expert. BACKGROUND Artificial intelligence is increasingly used to assess cardiac function and LVM from cardiac magnetic resonance images. METHODS Two hundred patients were identified from a registry of individuals who underwent vasodilator stress cardiac magnetic resonance. LVEF, LVM, and RVEF were determined using 3 fully automated commercial DL algorithms and by a clinical expert (CLIN) using conventional methodology. Additionally, LVEF values were classified according to clinically important ranges: <35%, 35% to 50%, and ≥50%. Both ejection fraction values and classifications made by the DL ejection fraction approaches were compared against CLIN ejection fraction reference. Receiver-operating characteristic curve analysis was performed to evaluate the ability of CLIN and each of the DL classifications to predict major adverse cardiovascular events. RESULTS Excellent correlations were seen for each DL-LVEF compared with CLIN-LVEF (r = 0.83-0.93). Good correlations were present between DL-LVM and CLIN-LVM (r = 0.75-0.85). Modest correlations were observed between DL-RVEF and CLIN-RVEF (r = 0.59-0.68). A >10% error between CLIN and DL ejection fraction was present in 5% to 18% of cases for the left ventricle and 23% to 43% for the right ventricle. LVEF classification agreed with CLIN-LVEF classification in 86%, 80%, and 85% cases for the 3 DL-LVEF approaches. There were no differences among the 4 approaches in associations with major adverse cardiovascular events for LVEF, LVM, and RVEF. CONCLUSIONS This study revealed good agreement between automated and expert-derived LVEF and similarly strong associations with outcomes, compared with an expert. However, the ability of these automated measurements to accurately classify left ventricular function for treatment decision remains limited. DL-LVM showed good agreement with CLIN-LVM. DL-RVEF approaches need further refinements.

Abstract
Heart failure (HF) is a common cause of morbimortality with different etiopathogenesis and prognosis between men and women. This review provides a brief overview of gender-based differences in response to pharmacological therapies of heart failure with or without reduced ejection fraction (EF). It focuses on the differences in therapy outcomes with angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARBs), angiotensin neprilysin inhibitors (ARNI), beta-adrenergic blockers, mineralocorticoid/aldosterone receptor antagonists, diuretics, ivabradine and digoxin. The baseline data originates from randomised controlled trials (RCTs) and large registries. We conclude that current guidelines recommending similar therapeutic approaches for both men and women are appropriate, while additional consideration should be given for different approaches regarding the use of ARBs, ACEi, and digoxin. Based on the available data, the ARBs might be considered a first-line therapy of HR for women instead of ACEi. Moreover, female patients should have stricter digoxin monitoring due to higher sensitivity and increased risk of complications. Finally, women are underrepresented in current clinical trials, and therefore future trials should aim to balance the gender recruitment disparity allowing sub-group analysis and comparisons between genders to guide individualised therapeutic strategies and appropriately targeted preventative steps.

Abstract
For the past two decades, heart failure (HF) has been classified into two phenotypes based on ejection fraction (EF). Inhibitors of the RAAS, neprilysin, , and beta-blockers represent foundational treatments for patients with a reduced EF (<40%) but have not been considered effective in patients with preserved EF (≥40%). However, re-examination of the clinical trial evidence has cast considerable doubt about the utility of an EF threshold of 40% as the main decision tool for HF treatment. In CHARM, candesartan reduced the risk of cardiovascular death or HF hospitalization by 24% up to an EF of 50%, with attenuation of the effect on HF hospitalization in patients with EF >55-60%. In RALES and TOPCAT, spironolactone reduced the risk of cardiovascular death or HF hospitalization by 28% up to an EF of 50%, with attenuation of the effect on HF hospitalization in patients with EF >55-60%. In PARADIGM-HF and PARAGON-HF, sacubitril/valsartan reduced total HF hospitalizations by 20% up to an EF of 55-60%, with an attenuated effect in patients with the highest EF. In the EMPEROR trials, empagliflozin reduced the risk of total HF hospitalizations by approximately 30% in patients with EF ranging from <25% to 60%, with an attenuated effect in patients with EF >60-65%. Since patients with an EF >60% represent only 10-15% of all HF patients, we propose that foundational HF treatments should be applied to patients across broad range of EF.

Abstract
BACKGROUND Type 2 diabetes mellitus is associated with an increased risk of developing heart failure. However, few recent studies have examined the characteristics of older adults living in US nursing homes with heart failure and diabetes mellitus. This study is important for clinical practice and public health action plans for heart failure. OBJECTIVE To estimate the prevalence of, and factors associated with, heart failure in long-stay nursing home residents with diabetes mellitus. METHODS We conducted a cross-sectional study using the US 2016 Minimum Data Set data consisting of all residents with diabetes aged ≥65 years in Medicare/Medicaid certified nursing homes (n = 297,570). Diabetes mellitus and heart failure were operationalized using the resident's transfer notes at admission and the progress notes during admission through physical examination findings and current treatment orders. RESULTS Among all residents with diabetes, 26.4% had heart failure. Increasing age of residents, and comorbidities including coronary artery disease (aOR: 1.34; 95% CI: 1.31-1.37), end stage renal disease (aOR: 1.30; 95% CI: 1.26-1.35), and chronic obstructive pulmonary disease (aOR: 1.60; 95% CI: 1.57-1.63) were associated with a higher odds of heart failure. CONCLUSIONS This is one of the first U.S studies to examine the prevalence and factors associated with heart failure in nursing home residents with diabetes mellitus. It highlights a clinically complex population with multiple comorbid conditions. Future research is needed to understand the pharmacological management of these residents and the extent to which appropriate management can improve quality of life for a medically vulnerable population.

Abstract
In randomised, placebo- or active-controlled trials in patients with heart failure with reduced ejection fraction (HFrEF), each of the combination of a neprilysin inhibitor and an angiotensin-receptor blocker (i.e. sacubitril/valsartan), a beta blocker, a mineralocorticoidreceptor antagonist and a sodium-glucose co-transporter 2 (SGLT2) inhibitor have been shown to reduce morbidity and mortality, firmly establishing the role of these five agents, prescribed as four pills, as foundational therapy for HFrEF. Traditionally, the guideline-advocated strategy for the initiation of these therapies was based on the historical order in which the landmark clinical trials were performed, and the requirement to uptitrate each individual drug to the target dose (or maximally tolerated dose below this) prior to initiation of another therapy. This process could take six months or more to complete, during which time patients would not be taking one or more of these life-saving drugs. Recently an alternative, evidence-based, rapid three-step sequencing strategy has been proposed with the aim of establishing HFrEF patients on low-doses of all four foundational treatments within four weeks. This strategy is based on the premise that the benefits of each of these therapies are independent and additive to the others, the benefits are apparent at low doses early following initiation, and a specific ordering of therapies may increase likelihood of tolerance of others. This article will outline this novel rapid-sequencing strategy and provide an evidence-based framework to support its adoption into clinical practice.

Abstract
OBJECTIVES This study sought to evaluate the frequency and nature of cost/value statements in contemporary heart failure (HF) clinical guidance documents (CGDs). BACKGROUND In an era of rising health care costs and expanding therapeutic options, there is an increasing need for formal consideration of cost and value in the development of HF CGDs. METHODS HF CGDs published by major professional cardiovascular organizations between January 2010 and February 2021 were reviewed for the inclusion of cost/value statements. RESULTS Overall, 33 documents were identified, including 5 (15%) appropriate use criteria, 7 (21%) clinical practice guidelines, and 21 (64%) expert consensus documents. Most CGDs (27 of 33; 82%) included at least 1 cost/value statement, and 20 (61%) CGDs included at least 1 cost/value-related citation. Most of these statements were found in expert consensus documents (77.7%). Three (9%) documents reported estimated costs of recommended interventions, but only 1 estimated out-of-pocket cost. Of 179 cost/value-related statements observed, 116 (64.8%) highlighted the economic impact of HF or HF-related care, 6 (3.4%) advocated for cost/value issues, 15 (8.4%) reported gaps in cost/value evidence, and 42 (23.5%) supported clinical guidance recommendations. Over time, patterns of inclusion of statements and citations of cost/value have been largely stable. CONCLUSIONS Although most contemporary HF CGDs contain at least 1 cost/value statement, most CGDs focus on the high economic impact of HF and its related care; explicit inclusion of cost/value to support clinical guidance recommendations remains infrequent. These results highlight key opportunities for the integration of formalized cost/value considerations in future HF-focused CGDs.

Abstract
Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical manifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%–60%), followed by heart failure (25%–30%) and stroke (10%–15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

Abstract
In heart failure (HF), acute decompensation can occur quickly and unexpectedly because of worsening of chronic HF or to new-onset HF diagnosed for the first time ('de novo'). Patients presenting with acute HF (AHF) have a poor prognosis comparable with those with acute myocardial infarction, and any delay of treatment initiation is associated with worse outcomes. Recent HF guidelines and recommendations have highlighted the importance of a timely diagnosis and immediate treatment for patients presenting with AHF to decrease disease progression and improve prognosis. However, based on the available data, there is still uncertainty regarding the optimal 'time-to-treatment' effect in AHF. Furthermore, the immediate post-worsening HF period plays an important role in clinical outcomes in HF patients after hospitalization and is known as the 'vulnerable phase' characterized by high risk of readmission and early death. Early and intensive treatment for HF patients in the 'vulnerable phase' might be associated with lower rates of early readmission and mortality. Additionally, in the chronic stable HF outpatient, treatments are often delayed or not initiated when symptoms are stable, ignoring the risk for adverse outcomes such as sudden death. Consequently, there is a dire need to better identify HF patients during hospitalization and after discharge and treating them adequately to improve their prognosis. HF is an urgent clinical scenario along all its stages and disease conditions. Therefore, time plays a significant role throughout the entire patient's journey. Therapy should be optimized as soon as possible, because this is beneficial regardless of severity or duration of HF. Time lavished before treatment initiation is recognized as important modifiable risk factor in HF.

Abstract
Background. Heart failure is a progressive condition marked by worsening symptoms such as shortness of breath, coughing, exhaustion and lethargy, fluid retention with swelling of the legs and abdomen, and a reduced ability to exercise. As a result, this study aims to use a joint model application to determine the joint risk factors of longitudinal change in pulse rate and time to death of congestive heart failure patients and their association admitted to a hospital. Methods. A retrospective study was undertaken on congestive heart failure patients admitted to the Debre Tabor Referral Hospital from January 2016 to December 2019. A statistical joint modeling strategy was employed to match the repeated biomarker pulse rate and a survival outcome at the same time. A total of 271 patients with congestive heart failure were chosen. Data were analyzed with R statistical software via joineRML. Results. According to the findings, the association between longitudinal changes in pulse rate and time to death in heart failure patients is statistically significant. Sex, residence, left ventricular injection fraction, New York Heart Association class, and diabetes mellitus were all found to be significant risk factors for congestive heart failure patients’ short survival time to death. Age, sex, residence, hypertension, left ventricular injection fraction, congestive heart failure, diabetes mellitus, tuberculosis, and etiology were all significant contributors in pulse rate progression. Conclusion. The computed association parameters revealed subject-specific values. The subject-specific linear time slope of PR measurement was positively related to the hazard rate of time to death of CHF patients in the study area. To reduce the risk level of CHF, health professionals, governmental organizations, and nongovernmental organizations must promote and allocate a suitable amount of budget for the treatment of CHF patients.

Abstract
BACKGROUND Angiotensin-converting enzyme inhibitor (ACEi) and angiotensin-receptor blocker (ARB) are cornerstones in the treatment of heart failure with reduced ejection (HFrEF). However, there are limited data on their risk-benefit profile in patients with acute heart failure requiring hospitalizations. METHODS We did a meta-analysis pooling data from all studies examining the use of ACEi/ARB in patients hospitalized for heart failure compared to patients without ACEi/ARB use. We calculated pooled hazard ratios (HR) and their 95% confidence intervals (CI) using a random-effects model. RESULTS Twenty-five studies were included in the meta-analysis. Continued use of ACEi/ARBs in hospitalized patients with HFrEF was associated with lower 1-year mortality risk (pooled HR 0.68 [0.60-0.77] p < 0.001) and with lower 1-6-year mortality risk in those with heart failure preserved ejection fraction (HFpEF) (pooled HR 0.86 [0.78-0.94] p = 0.002). There were significant reductions in 1-year HF readmissions among hospitalized HFrEF patients (pooled HR 0.83 [0.73-0.95] p = 0.005). CONCLUSION Maintaining or initiating patients with HFrEF hospitalized for acute decompensated heart failure (ADHF) on ACEi/ARB is associated with a reduce risk of mortality and 1-year admissions, but the effect size is lower among those with HFpEF with more heterogeneous outcomes.

Abstract
BACKGROUND This study evaluated the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of single ascending doses (SAD) and multiple ascending doses (MAD) of S086 in healthy Chinese volunteers. RESEARCH DESIGN AND METHODS This randomized, double-blind, placebo-controlled, Phase I clinical trial enrolled 113 subjects, including 65 subjects in the SAD (60-1080 mg) study and 48 subjects in the MAD study (180-720 mg). The safety, PK (sacubitril, LBQ657, and EXP3174) and PD (MAD study: blood pressure, pulse) of S086 were assessed. RESULTS There were no deaths, serious adverse events, or discontinuations due to TEAEs, and there were no significant safety concerns associated with S086. PK parameters for sacubitril, LBQ657, and EXP3174 increased in a dose-dependent manner after single oral doses of S086. Plasma concentrations of sacubitril, LBQ657, and EXP3174 were maintained at steady state within 5 days of once-daily oral administration of S086. In the MAD study, S086 administration was associated with a dose-dependent decrease in mean diastolic and systolic blood pressure compared to baseline. CONCLUSIONS The safety and PK profile profiles of S086 support the use of S086 240 mg once daily in a future Phase II study in patients with heart failure. TRIAL REGISTRATION The trial is registered at chinadrugtrials.org.cn (CT.gov identifier: CTR20182350 and CTR20182351).

Abstract
Usually, heart failure occurs when heart-related diseases are developed and continue to deteriorate veins and arteries. Heart failure is the final stage of heart disease, and it has become an important medical problem, particularly among the aging population. In medical diagnosis and treatment, the examination of heart failure contains various indicators such as electrocardiogram. It is one of the relatively common ways to collect heart failure or attack related information and is also used as a reference indicator for doctors. Electrocardiogram indicates the potential activity of patient's heart and directly reflects the changes in it. In this paper, a deep learning-based diagnosis system is presented for the early detection of heart failure particularly in elderly patients. For this purpose, we have used two datasets, Physio-Bank and MIMIC-III, which are publicly available, to extract ECG signals and thoroughly examine heart failure. Initially, a heart failure diagnosis model which is based on attention convolutional neural network (CBAM-CNN) is proposed to automatically extract features. Additionally, attention module adaptively learns the characteristics of local features and efficiently extracts the complex features of the ECG signal to perform classification diagnosis. To verify the exceptional performance of the proposed network model, various experiments were carried out in the realistic environment of hospitals. Influence of signal preprocessing on the performance of model is also discussed. These results show that the proposed CBAM-CNN model performance is better for both classifications of ECG signals. Likewise, the CBAM-CNN model is sensitive to noise, and its accuracy is effectively improved as soon as signal is refined.

Abstract
Importance The use of sacubitril/valsartan is not endorsed by practice guidelines for use in patients with New York Heart Association class IV heart failure with a reduced ejection fraction because of limited clinical experience in this population. Objective To compare treatment with sacubitril/valsartan treatment with valsartan in patients with advanced heart failure and a reduced ejection fraction and recent New York Heart Association class IV symptoms. Design, Setting, and Participants A double-blind randomized clinical trial was conducted; a total of 335 patients with advanced heart failure were included. The trial began on March 2, 2017, and was stopped early on March 23, 2020, owing to COVID-19 risk. Intervention Patients were randomized to receive sacubitril/valsartan (target dose, 200 mg twice daily) or valsartan (target dose, 160 mg twice daily) in addition to recommended therapy. Main Outcomes and Measures The area under the curve (AUC) for the ratio of N-terminal pro-brain natriuretic peptide (NT-proBNP) compared with baseline measured through 24 weeks of therapy. Results Of the 335 patients included in the analysis, 245 were men (73%); mean (SD) age was 59.4 (13.5) years. Seventy-two eligible patients (18%) were not able to tolerate sacubitril/valsartan, 100 mg/d, during the short run-in period, and 49 patients (29%) discontinued sacubitril/valsartan during the 24 weeks of the trial. The median NT-proBNP AUC for the valsartan treatment arm (n = 168) was 1.19 (IQR, 0.91-1.64), whereas the AUC for the sacubitril/valsartan treatment arm (n = 167) was 1.08 (IQR, 0.75-1.60). The estimated ratio of change in the NT-proBNP AUC was 0.95 (95% CI 0.84-1.08; P = .45). Compared with valsartan, treatment with sacubitril/valsartan did not improve the clinical composite of number of days alive, out of hospital, and free from heart failure events. Aside from a statistically significant increase in non-life-threatening hyperkalemia in the sacubitril/valsartan arm (28 [17%] vs 15 [9%]; P = .04), there were no observed safety concerns. Conclusions and Relevance The findings of this trial showed that, in patients with chronic advanced heart failure with a reduced ejection fraction, there was no statistically significant difference between sacubitril/valsartan and valsartan with respect to reducing NT-proBNP levels.

Abstract
The biogenic amine, histamine, is found predominantly in mast cells, as well as specific histaminergic neurons. Histamine exerts its many and varied actions via four G-protein-coupled receptors numbered one through four. Histamine has multiple effects on cardiac physiology, mainly via the histamine 1 and 2 receptors, which on a simplified level have opposing effects on heart rate, force of contraction, and coronary vasculature function. In heart failure, the actions of the histamine receptors are complex, the histamine 1 receptor appears to have detrimental actions predominantly in the coronary vasculature, while the histamine 2 receptor mediates adverse effects on cardiac remodeling via actions on cardiomyocytes, fibroblasts, and even endothelial cells. Conversely, there is growing evidence that the histamine 3 receptor exerts protective actions when activated. Little is known about the histamine 4 receptor in heart failure. Targeting histamine receptors as a therapeutic approach for heart failure is an important area of investigation given the over-the-counter access to many compounds targeting these receptors, and thus the relatively straight forward possibility of drug repurposing. In this review, we briefly describe histamine receptor signaling and the actions of each histamine receptor in normal cardiac physiology, before describing in more detail the known role of each histamine receptor in adverse cardiac remodeling and heart failure. This includes information from both clinical studies and experimental animal models. It is the goal of this review article to bring more focus to the possibility of targeting histamine receptors as therapy for heart failure.

Abstract
This study tested the hypothesis that Entresto (En) therapy protected the cardiomyocytes and heart function in cardiorenal syndrome (CRS) rats fed with high-protein diet (HPD) through regulating the oxidative-stress and Mfn2-mediated mitochondrial functional integrity. En (12.5 μM for the in-vitro study) protected the H9C2-cells against H2O2-induced cell apoptosis, whereas stepwise-increased H2O2 concentrations induced a significant increase in protein expressions of Mfn2/phosphorylated (p)-DRP1/mitochondrial-Bax in H9C2-cells. En downregulated H2O2-induced mitochondrial fission/upregulated mitochondrial fusion and deletion of Mfn2 gene (i.e., shMfn2) to significantly reduce H2O2-induced ROS production. En significantly suppressed and shMfn2 further significantly suppressed both H2O2-reduced mitochondrial-membrane potential and H2O2-induced ROS production/cell apoptosis/mitochondrial damage/mitochondrial-Bax released from mitochondria in H9C2 cells. En significantly reduced protein expressions of Mfn2 and p-DRP1. Additionally, En significantly suppressed and shMfn2 further significantly suppressed the protein expressions of mitochondrial-damaged (DRP1)/oxidative-stress (NOX-1/NOX-2)/apoptosis (mitochondrial-Bax/caspase-3/PARP)/autophagic (LC3B-II/LC3B-I) biomarkers (all p < 0.01). Rats were categorized into group 1 [sham-control + high-protein-diet (HPD)], group 2 (CRS + HPD) and group 3 (CRS+ HPD + En/100 mg/kg/day). By day 63 after CRS induction, the LVEF was significantly lower in group 3 and more significantly lower in group 2 than in group 1, whereas the protein expressions of oxidative-stress (NOX-1/NOX-2/p22phox/oxidized protein)/apoptotic (mitochondrial-Bax/caspase-3/PARP), fibrotic (Smad-3/TGF-ß), autophagic (Beclin-1/Atg5/ratio of LC3B-II/LC3B-I) and mitochondrial-damaged (DRP1/cyclophilin-D/cytosolic-cytochrome-C) biomarkers exhibited an opposite pattern of LVEF among the groups. Downregulation of Mfn2 by En or shMfn2 in cardiomyocytes avoided H2O2 damage and En improved the cardiac function in HPD-feeding CRS rat via adjusting Mfn2-mediated mitochondrial functional integrity.

Pharmacotherapy 2021; 41:978-987. [PMID: 34569641 DOI: 10.1002/phar.2626] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 08/21/2021] [Accepted: 09/06/2021] [Indexed: 01/08/2023]
Abstract
STUDY OBJECTIVE This study aimed to determine if variants in NR3C2, which codes the target protein of spironolactone, or CYP11B2, which is involved in aldosterone synthesis, were associated with spironolactone response, focused on the primary end point of diastolic function (E/e'), in Aldosterone Receptor Blockade in Diastolic Heart Failure (Aldo-DHF) participants. DESIGN Post-hoc genetic analysis. DATA SOURCE Data and samples were derived from the multi-center, randomized, double-blind, placebo-controlled Aldo-DHF trial. PATIENTS Aldo-DHF participants treated with spironolactone (n = 184) or placebo (n = 178) were included. INTERVENTION Participants were genotyped for NR3C2 rs5522, NR3C2 rs2070951 and CYP11B2 rs1799998 via pyrosequencing. MEASUREMENTS In the placebo and spironolactone arms, separate multivariable linear regression analyses were performed for change in E/e' with each single nucleotide polymorphism (SNP), adjusted for age, sex, and baseline E/e'. To discern potential mechanisms of a genotype effect, associated SNPs were further examined for their association with change in blood pressure, circulating procollagen type III N-terminal peptide (PIIINP), and left atrial area. MAIN RESULTS Carriers of the rs5522 G allele in the placebo arm had a greater increase in E/e' over the 12-month course of the trial compared to noncarriers (β = 1.10; 95% confidence interval [CI]: 0.05-2.16; p = 0.04). No corresponding E/e' worsening by rs5522 genotype was observed in the spironolactone arm. None of the other genotypes were associated with change in E/e'. Compared to noncarriers, rs5522 G carriers also had a greater increase in left atrial area with placebo (β = 0.83; 95% CI: 0.17-1.48; p = 0.01) and a greater reduction in diastolic blood pressure with spironolactone (β = -3.56; 95% CI: -6.73 to -0.39; p = 0.03). Serum PIIINP levels were similar across rs5522 genotypes. CONCLUSIONS Our results suggest that spironolactone attenuates progression of diastolic dysfunction associated with the NR3C2 rs5522 G allele. Validation of our findings is needed.

Abstract
The cardiac hyperpolarization-activated “funny” current (If), which contributes to sinoatrial node (SAN) pacemaking, has a more negative half-maximal activation voltage and smaller fully-activated macroscopic conductance in human than in rabbit SAN cells. The consequences of these differences for the relative roles of If in the two species, and for their responses to the specific bradycardic agent ivabradine at clinical doses have not been systematically explored. This study aims to address these issues, through incorporating rabbit and human If formulations developed by Fabbri et al. into the Severi et al. model of rabbit SAN cells. A theory was developed to correlate the effect of If reduction with the total inward depolarising current (Itotal) during diastolic depolarization. Replacing the rabbit If formulation with the human one increased the pacemaking cycle length (CL) from 355 to 1,139 ms. With up to 20% If reduction (a level close to the inhibition of If by ivabradine at clinical concentrations), a modest increase (~5%) in the pacemaking CL was observed with the rabbit If formulation; however, the effect was doubled (~12.4%) for the human If formulation, even though the latter has smaller If density. When the action of acetylcholine (ACh, 0.1 nM) was considered, a 20% If reduction markedly increased the pacemaking CL by 37.5% (~27.3% reduction in the pacing rate), which is similar to the ivabradine effect at clinical concentrations. Theoretical analysis showed that the resultant increase of the pacemaking CL is inversely proportional to the magnitude of Itotal during diastolic depolarization phase: a smaller If in the model resulted in a smaller Itotal amplitude, resulting in a slower pacemaking rate; and the same reduction in If resulted in a more significant change of CL in the cell model with a smaller Itotal. This explained the mechanism by which a low dose of ivabradine slows pacemaking rate more in humans than in the rabbit. Similar results were seen in the Fabbri et al. model of human SAN cells, suggesting our observations are model-independent. Collectively, the results of study explain why low dose ivabradine at clinically relevant concentrations acts as an effective bradycardic agent in modulating human SAN pacemaking.

Abstract
BACKGROUND This study sought to evaluate the performance of machine learning (ML) models and establish an explainable ML model with good prediction of 3-year all-cause mortality in patients with heart failure (HF) caused by coronary heart disease (CHD). METHODS We established six ML models using follow-up data to predict 3-year all-cause mortality. Through comprehensive evaluation, the best performing model was used to predict and stratify patients. The log-rank test was used to assess the difference between Kaplan-Meier curves. The association between ML risk and 3-year all-cause mortality was also assessed using multivariable Cox regression. Finally, an explainable approach based on ML and the SHapley Additive exPlanations (SHAP) method was deployed to calculate 3-year all-cause mortality risk and to generate individual explanations of the model's decisions. RESULTS The best performing extreme gradient boosting (XGBoost) model was selected to predict and stratify patients. Subjects with a higher ML score had a high hazard of suffering events (hazard ratio [HR]: 10.351; P < 0.001), and this relationship persisted with a multivariable analysis (adjusted HR: 5.343; P < 0.001). Age, N-terminal pro-B-type natriuretic peptide, occupation, New York Heart Association classification, and nitrate drug use were important factors for both genders. CONCLUSIONS The ML-based risk stratification tool was able to accurately assess and stratify the risk of 3-year all-cause mortality in patients with HF caused by CHD. ML combined with SHAP could provide an explicit explanation of individualized risk prediction and give physicians an intuitive understanding of the influence of key features in the model.

Abstract
OBJECTIVE The effect of renin-angiotensin system inhibitors (RASIs) in patients with heart failure (HF) and atrial fibrillation (AF) remains unclear. This study aimed to investigate associations between RASI use and all-cause mortality and cardiovascular outcomes in patients with AF and HF. METHODS Using data from the China Atrial Fibrillation Registry study, we included 938 patients with AF and HF with a left ventricular ejection fraction <50%. Cox regression models for RASIs vs. non-RASIs with all-cause mortality as the primary outcome were fitted in a 1:1 propensity score-matched cohort. A sensitivity analysis was performed by using a multivariable time-dependent Cox regression model. As an internal control, we assessed the relation between β-blocker use and all-cause mortality. RESULTS During a mean follow-up of 35 months, the risk of all-cause mortality was similar in RASI users compared with non-users (hazard ratio: 0.92; 95% confidence interval: 0.67-1.26). Similar results were obtained in the sensitivity analysis. In contrast, β-blocker use was associated with significantly lower all-cause mortality in the same population. CONCLUSIONS RASI use was not associated with better outcomes in patients with AF and HF in this prospective cohort, which raises questions about their value in this specific subset.Trail Registration: ChiCTR-OCH-13003729.

Abstract
Characterized by a rapidly increasing prevalence, elevated mortality and rehospitalization rates, and inadequacy of pharmaceutical therapies, heart failure with preserved ejection fraction (HFpEF) has motivated the widespread development of device-based solutions. HFpEF is a multifactorial disease of various etiologies and phenotypes, distinguished by diminished ventricular compliance, diastolic dysfunction, and symptoms of heart failure despite a normal ejection performance; these symptoms include pulmonary hypertension, limited cardiac reserve, autonomic imbalance, and exercise intolerance. Several types of atrial shunts, left ventricular expanders, stimulation-based therapies, and mechanical circulatory support devices are currently under development aiming to target one or more of these symptoms by addressing the associated mechanical or hemodynamic hallmarks. Although the majority of these solutions have shown promising results in clinical or preclinical studies, no device-based therapy has yet been approved for the treatment of patients with HFpEF. The purpose of this review is to discuss the rationale behind each of these devices and the findings from the initial testing phases, as well as the limitations and challenges associated with their clinical translation.

Abstract
Chronic heart failure (CHF) is frequently associated with the involuntary loss of body weight and muscle wasting, which can determine the course of the disease and its prognosis. While there is no gold standard malnutrition screening tool for their detection in the CHF population, several bioelectrical and imaging methods have been used to assess body composition in these patients (such as Dual Energy X-Ray Absorptiometry and muscle ultrasound, among other techniques). In addition, numerous nutritional biomarkers have been found to be useful in the determination of the nutritional status. Nutritional considerations include the slow and progressive supply of nutrients, avoiding high volumes, which could ultimately lead to refeeding syndrome and worsen the clinical picture. If oral feeding is insufficient, hypercaloric and hyperproteic supplementation should be considered. β-Hydroxy-β-methylbutyrate and omega-3 polyunsaturated fatty acid administration prove to be beneficial in certain patients with CHF, and several interventional studies with micronutrient supplementation have also described their possible role in these subjects. Taking into account that CHF is sometimes associated with gastrointestinal dysfunction, parenteral nutritional support may be required in selected cases. In addition, potential therapeutic options regarding nutritional state and muscle wasting have also been tested in clinical studies. This review summarises the scientific evidence that demonstrates the necessity to carry out a careful nutritional evaluation and nutritional treatment to prevent or improve cardiac cachexia and sarcopenia in CHF, as well as improve its course.

Abstract
BACKGROUND Arrhythmogenic right ventricular cardiomyopathy type 5 (ARVC5) is an inherited cardiac disease with complete penetrance and an aggressive clinical course caused by mutations in TMEM43 (transmembrane protein 43). There is no cure for ARVC5 and palliative treatment is started once the phenotype is present. A transgenic mouse model of ARVC5 expressing human TMEM43-S358L (TMEM43mut) recapitulates the human disease, enabling the exploration of preventive treatments. The aim of this study is to determine whether preventive treatment with heart failure drugs (β-blockers, ACE [angiotensin-converting enzyme] inhibitors, mineralocorticoid-receptor antagonists) improves the disease course of ARVC5 in TMEM43mut mice. METHODS TMEM43mut male/female mice were treated with metoprolol (β-blockers), enalapril (ACE inhibitor), spironolactone (mineralocorticoid-receptor antagonist), ACE inhibitor + mineralocorticoid-receptor antagonist, ACE inhibitor + mineralocorticoid-receptor antagonist + β-blockers or left untreated. Drugs were initiated at 3 weeks of age, before ARVC5 phenotype, and serial ECG and echocardiograms were performed. RESULTS TMEM43mut mice treated with enalapril showed a significantly increased median survival compared with untreated mice (26 versus 21 weeks; P=0.003). Enalapril-treated mice also exhibited increased left ventricular ejection fraction at 4 months compared with controls (37.0% versus 24.9%; P=0.004), shorter QRS duration and reduced left ventricle fibrosis. Combined regimens including enalapril also showed positive effects. Metoprolol decreased QRS voltage prematurely and resulted in a nonsignificant decrease in left ventricular ejection fraction compared with untreated TMEM43mut mice. CONCLUSIONS Preventive enalapril-based regimens reduced fibrosis, improved ECG, echocardiographic parameters and survival of ARVC5 mice. Early metoprolol did not show positive effects and caused premature ECG abnormalities. Our findings pave the way to consider prophylactic enalapril in asymptomatic ARVC5 genetic carriers.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Hypericum are widely distributed in China. Hypericum perforatum L. (genus Hypericum, family Hypericaceae) has a long history as a traditional Chinese medicine, which was traditionally used for the treatment of emotional distress, cardiothoracic depression, and acute mastitis. Hyperoside (Hyp) extracted from Hypericum perforatum L. has been affirmed to exert therapeutic effects on cardiovascular diseases, with widespread existence in plants of genus Hypericum. Hyp could also be extracted from Crataegus pinnatifida Bunge (genus Crataegus pinnatifida Bunge, family Rosaceae), another traditional Chinese medicine that traditionally prevented and treated heart disease in China. The cardioprotection and mechanism of Hyp comprise anti-inflammation, anti-fibrosis, activation of autophagy, and reversal of cardiac remodeling. AIM OF THE STUDY This study aimed to explore the Hyp effect against MI and its underlying mechanism. MATERIALS AND METHODS The MI model was constructed in the KM mice via a ligating surgery of the left anterior descending (LAD) coronary artery. Subsequently, the mice were divided into following seven groups: Sham group, MI group, MI + Hyp 9 mg/kg group, MI + Hyp18 mg/kg group, MI + Hyp36 mg/kg group, MI + Fosinopril group, and MI + Hyp-36 mg/kg+3-MA group. Each group was treated with Hyp in different concentrations or positive medicine for two weeks except for the sham group. After two weeks, we examined the cardiac function, electrocardiogram (ECG), myocardial hypertrophy in the non-infarct area, collagen volume fraction (CVF), perivascular collagen area (PVCA) in the infarct area, and several serum cytokines. Autophagy and inflammation in cardiomyocytes were assessed via measuring autophagy-associated proteins and NLRP1 inflammasome pathway related proteins. RESULTS Hyp reversed LV remodeling and adverse ECG changes through reducing CVF and myocardial hypertrophy. Additionally, Hyp treatment could reduce inflammation levels in cardiomyocytes, compared with those in MI group. Moreover, NLRP1inflammation pathway was activated after MI. Up-regulation of autophagic flux suppressed NLRP1 inflammation pathway after Hyp treatment. However, co-treatment with 3-MA abrogated above effects of Hyp. CONCLUSIONS Hyp had obvious protective effect on heart injury in MI mice. Echocanrdiographic and histological measurements demonstrated that Hyp treatment improved cardiac function, and ameliorated myocardial hypertrophy and fibrinogen deposition after MI. The partial mechanism is that Hyp could up-regulate autophagy after MI. Furthermore, the promotion of autophagic flux would suppress NLRP1 inflammation pathway induced by MI.

Abstract
Cardiac resynchronization therapy (CRT) is one of the most effective therapies for heart failure with reduced ejection fraction and leads to improved quality of life, reductions in heart failure hospitalization rates and all-cause mortality. Nevertheless, up to two-thirds of eligible patients are not referred for CRT. Furthermore, post-implantation follow-up is often fragmented and suboptimal, hampering the potential maximal treatment effect. This joint position statement from three European Society of Cardiology Associations, Heart Failure Association (HFA), European Heart Rhythm Association (EHRA) and European Association of Cardiovascular Imaging (EACVI), focuses on optimized implementation of CRT. We offer theoretical and practical strategies to achieve more comprehensive CRT referral and post-procedural care by focusing on four actionable domains: (i) overcoming CRT under-utilization, (ii) better understanding of pre-implant characteristics, (iii) abandoning the term 'non-response' and replacing this by the concept of disease modification, and (iv) implementing a dedicated post-implant CRT care pathway.

Left-ventricular dyssynchrony in viable myocardium by myocardial perfusion SPECT is predictive of mechanical response to CRT. Ann Nucl Med 2021; 35:947-954. [PMID: 34021491 PMCID: PMC10962318 DOI: 10.1007/s12149-021-01632-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 05/17/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVES Gated myocardial perfusion SPECT (GMPS) provides a one-stop-shop evaluation for cardiac resynchronization therapy (CRT). However, conflicting results have been observed regarding whether the baseline left-ventricular (LV) mechanical dyssynchrony as assessed by phase analysis on GMPS was predictive of therapeutic response to CRT. Since dyssynchrony parameters by phase analysis spuriously increased by scarred myocardium, the purpose of this study was to explore the value of dyssynchrony after stripping off the scar region in correlation to mechanical response to CRT. METHODS Forty-seven patients following standard indications for CRT received GMPS with phase analysis as pre-CRT evaluation. A decrease of end-systolic volume (ESV) > 15% on follow-up echocardiography after CRT was considered as a mechanical response to CRT. Myocardial regions with less than 50% of maximal activity on GMPS were considered as a scar. The phase standard deviation (PSD) and histogram bandwidth (BW) without or with stripping off scar were assessed by phase analysis of GMPS and were used for evaluation of LV dyssynchrony of all myocardium or only the viable myocardium, respectively. RESULTS No significant difference was noted between mechanical responders (31 of 47 patients, 66%) and nonresponders ( 16 of 47 patients, 34%) for PSD (48.6° ± 19.4° vs 43.9° ± 20.7°, p = 0.46) and BW (225° ± 91.1° vs 163.5° ± 94.6°, p = 0.38) of the entire myocardium. However, responders had significantly larger PSD (40.5° ± 15.7° vs 30.5° ± 13.2°, p = 0.03) and borderlinely larger BW (215° ± 91.2° vs. 139.5° ± 78.2°, p = 0.05) than non-responders after stripping off scar. Logistic regression analysis showed that scar area and PSD after stripping off scar were independent predictors of mechanical response. CONCLUSIONS Our result showed that LV dyssynchrony of the entire myocardium did not predict response to CRT. However, LV dyssynchrony only in the viable myocardium was a significant predictor of CRT mechanical response.

Renal function and the effects of vericiguat in patients with worsening heart failure with reduced ejection fraction: insights from the VICTORIA (Vericiguat Global Study in Subjects with HFrEF) trial. Eur J Heart Fail 2021; 23:1313-1321. [PMID: 33999486 PMCID: PMC8453520 DOI: 10.1002/ejhf.2221] [Citation(s) in RCA: 48] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 05/11/2021] [Accepted: 05/11/2021] [Indexed: 12/15/2022] Open
Abstract
AIMS Vericiguat reduced the primary composite outcome of cardiovascular death or heart failure (HF) hospitalization in patients with worsening HF with reduced ejection fraction (HFrEF) and a lower limit of baseline estimated glomerular filtration rate (eGFR) of 15 mL/min/1.73 m2 . We evaluated the relationship between the efficacy of vericiguat and baseline and subsequent changes in renal function. METHODS AND RESULTS In VICTORIA, core laboratory serum creatinine was measured at baseline (n = 4956) and weeks 16, 32, and 48. Worsening renal function (WRF), defined as an increase ≥0.3 mg/dL in creatinine from baseline to week 16, was assessed via a Cox model with respect to subsequent primary events. Mean age was 69 years, 24% were female, and mean baseline eGFR was 61 mL/min/1.73 m2 . During 48 weeks of treatment, the trajectories in eGFR and creatinine with vericiguat were similar to placebo (P = 0.50 and 0.18). The beneficial effects of vericiguat on the primary outcome were not influenced by baseline eGFR (interaction P = 0.48). WRF occurred in 15% of patients and was associated with worse outcomes (adjusted hazard ratio 1.28, 95% confidence interval 1.11-1.47; P < 0.001), but the beneficial effects of vericiguat on the primary outcome were similar in patients with or without WRF (interaction P = 0.76). CONCLUSION Renal function trajectories were similar between vericiguat- and placebo-treated patients and the beneficial effects of vericiguat on the primary outcome were consistent across the full range of eGFR and irrespective of WRF.

Effect of Ticagrelor on Left Ventricular Remodeling in Patients With ST-Segment Elevation Myocardial Infarction (HEALING-AMI). JACC Cardiovasc Interv 2021; 13:2220-2234. [PMID: 33032710 DOI: 10.1016/j.jcin.2020.08.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 07/17/2020] [Accepted: 08/04/2020] [Indexed: 12/30/2022]
Abstract
OBJECTIVES The aim of this study was to evaluate the effect of ticagrelor versus clopidogrel on left ventricular (LV) remodeling after reperfusion of ST-segment elevation myocardial infarction (STEMI) in humans. BACKGROUND Animal studies have demonstrated that ticagrelor compared with clopidogrel better protects myocardium against reperfusion injury and improves remodeling after myocardial infarction. METHODS In this investigator-initiated, randomized, open-label, assessor-blinded trial performed at 10 centers in Korea, patients were enrolled if they had naive STEMI successfully treated with primary percutaneous coronary intervention (PCI) and at least 6-month planned duration of dual-antiplatelet treatment. The coprimary endpoints were LV remodeling index (LVRI) (a relative change of LV end-diastolic volume) measured on 3-dimensional echocardiography and N-terminal pro-B-type natriuretic peptide level at 6 months. RESULTS Among initially enrolled patients with STEMI (n = 336), 139 in each group completed the study. LVRI at 6 months was numerically lower with ticagrelor versus clopidogrel (0.6 ± 18.6% vs. 4.5 ± 16.5%; p = 0.095). Ticagrelor significantly reduced the 6-month level of N-terminal pro-B-type natriuretic peptide (173 ± 141 pg/ml vs. 289 ± 585 pg/ml; p = 0.028). These differences were prominent in patients with pre-PCI TIMI (Thrombolysis In Myocardial Infarction) flow grade 0. By multivariate analysis, ticagrelor versus clopidogrel reduced the risk for positive LV remodeling (LVRI >0%) (odds ratio: 0.56; 95% confidence interval: 0.33 to 0.95; p = 0.030). The LV end-diastolic volume index remained unchanged during ticagrelor treatment (from 54.7 ± 12.2 to 54.2 ± 12.2 ml/m2; p = 0.629), but this value increased over time during clopidogrel treatment (from 54.6 ± 11.3 to 56.4 ± 13.9 ml/m2; p = 0.056) (difference -2.3 ml/m2; 95% confidence interval: -4.8 to 0.2 ml/m2; p = 0.073). Ticagrelor reduced LV end-systolic volume index (from 27.0 ± 8.5 to 24.7 ± 8.4 ml/m2; p < 0.001), whereas no reduction was seen with clopidogrel (from 26.2 ± 8.9 to 25.6 ± 11.0 ml/m2; p = 0.366) (difference -1.8 ml/m2; 95% confidence interval: -3.5 to -0.1 ml/m2; p = 0.040). CONCLUSIONS Ticagrelor was superior to clopidogrel for LV remodeling after reperfusion of STEMI with primary PCI.

Abstract
Aims Patient‐performed lung ultrasound (LUS) in a heart failure (HF) telemedicine model may be used to monitor worsening pulmonary oedema and to titrate therapy, potentially reducing HF admission. The aim of the study was to assess the feasibility of training HF patients to perform a LUS self‐exam in a telemedicine model. Methods and results A pilot study was conducted at a public hospital involving subjects with a history of HF. After a 15 min training session involving a tutorial video, subjects performed a four‐zone LUS using a handheld ultrasound. Exams were saved on a remote server and independently reviewed by two LUS experts. Studies were determined interpretable according to a strict definition: the presence of an intercostal space, and the presence of A‐lines, B‐lines, or both. Subjects also answered a questionnaire to gather feedback and assess self‐efficacy. The median age of 44 subjects was 53 years (range, 36–64). Thirty (68%) were male. Last educational level attained was high school or below for 31 subjects (70%), and one‐third used Spanish as their preferred language. One hundred fifty of 175 lung zones (85%) were interpretable, with expert agreement of 87% and a kappa of 0.49. 98% of subjects reported that they could perform this LUS self‐exam at home. Conclusions This pilot study reports that training HF patients to perform a LUS self‐exam is feasible, with reported high self‐efficacy. This supports further investigation into a telemedicine model using LUS to reduce emergency department visits and hospitalizations associated with HF.

Mil Med Res 2021; 8:38. [PMID: 34238369 PMCID: PMC8268364 DOI: 10.1186/s40779-021-00330-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 06/01/2021] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND The clinical efficiency of routine oxygen therapy is uncertain in patients with acute heart failure (AHF) who do not have hypoxemia. The aim of this study was to investigate the association between oxygen therapy and clinical outcomes in normoxemic patients hospitalized with AHF using real-world data. METHODS Normoxemic patients diagnosed with AHF on ICU admission from the electronic ICU (eICU) Collaborative Research Database were included in the current study, in which the study population was divided into the oxygen therapy group and the ambient-air group. Propensity score matching (PSM) was applied to create a balanced covariate distribution between patients receiving supplemental oxygen and those exposed to ambient air. Linear regression and logistic regression models were performed to assess the associations between oxygen therapy and length of stay (LOS), and all-cause in-hospital as well as ICU mortality rates, respectively. A series of sensitivity and subgroup analyses were conducted to further validate the robustness of our findings. RESULTS A total of 2922 normoxemic patients with AHF were finally included in the analysis. Overall, 42.1% (1230/2922) patients were exposed to oxygen therapy, and 57.9% (1692/2922) patients did not receive oxygen therapy (defined as the ambient-air group). After PSM analysis, 1122 pairs of patients were matched: each patient receiving oxygen therapy was matched with a patient without receiving supplemental oxygen. The multivariable logistic model showed that there was no significant interaction between the ambient air and oxygen group for all-cause in-hospital mortality [odds ratio (OR) 1.30; 95% confidence interval (CI) 0.92-1.82; P = 0.138] or ICU mortality (OR 1.39; 95% CI 0.83-2.32; P = 0.206) in the post-PSM cohorts. In addition, linear regression analysis revealed that oxygen therapy was associated with prolonged ICU LOS (OR 1.11; 95% CI 1.06-1.15; P < 0.001) and hospital LOS (OR 1.06; 95% CI 1.01-1.10; P = 0.009) after PSM. Furthermore, the absence of an effect of supplemental oxygen on mortality was consistent in all subgroups. CONCLUSION Routine use of supplemental oxygen in AHF patients without hypoxemia was not found to reduce all-cause in-hospital mortality or ICU mortality.

Integrating High-Sensitivity Troponin T and Sacubitril/Valsartan Treatment in HFpEF: The PARAGON-HF Trial. JACC-HEART FAILURE 2021; 9:627-635. [PMID: 34246603 DOI: 10.1016/j.jchf.2021.04.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/20/2021] [Accepted: 04/27/2021] [Indexed: 12/28/2022]
Abstract
OBJECTIVES This study examined the relationship among high-sensitivity troponin-T (hs-TnT), outcomes, and treatment with sacubitril/valsartan in patients with heart failure (HF) and preserved ejection fraction (HFpEF). BACKGROUND hs-TnT is a marker of myocardial injury in HF. METHODS The PARAGON-HF trial randomized 4,796 patients with HFpEF to sacubitril/valsartan or valsartan. We compared the risk of the composite outcome of cardiovascular death (CVD) and total HF hospitalization (HHF) according to hs-TnT. We also assessed the effect of allocated treatment on hs-TnT. RESULTS hs-TnT was available in 1,141 patients (24%) at run-in (median value: 17 ng/L) and 1,260 (26%) at randomization, with 58.3% having hs-TnT >14 ng/L (upper limit of normal). During a median follow-up of 34 months, there were 393 outcome events (82 CVD, 311 HHF). Adjusting for demographics, comorbidities, left ventricular ejection fraction (LVEF), and N-terminal pro B-type natriuretic peptide (NT-proBNP), log-hs-TnT at randomization was an independent predictor of the composite outcome (HR: 1.38; 95% CI: 1.19-1.59; P < 0.001). Compared with valsartan, sacubitril/valsartan significantly reduced hs-TnT by 9% at week 16 (P < 0.001). Patients whose hs-TnT decreased from randomization to 16 weeks to at or below the median value of 17 ng/L subsequently had a lower risk of CVD/HHF compared with those with persistently elevated hs-TnT (P = 0.046). Patients with higher baseline hs-TnT (>17 ng/L) appeared to have a greater benefit from sacubitril/valsartan treatment when accounting for other potential effect modifiers (P interaction = 0.07). CONCLUSIONS Higher baseline hs-TnT was associated with increased risk of CVD/HHF, whereas hs-TnT decrease at 16 weeks led to lower subsequent risk of CVD/HHF compared with those who had persistently elevated values. Sacubitril/valsartan significantly reduced hs-TnT compared with valsartan. hs-TnT may be helpful in identifying patients with HFpEF who are more likely to benefit from sacubitril/valsartan.

Al-Balushi S, Alam MF, Abid AR, Sharfi A. The Effect of Ivabradine on Hospitalization of Heart Failure Patients: A Retrospective Cohort Study. Heart Views 2021; 22:165-173. [PMID: 34760047 PMCID: PMC8574096 DOI: 10.4103/heartviews.heartviews_23_20] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 08/08/2021] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Ivabradine is recommended in heart failure (HF) patients to reduce cardiovascular death and hospitalization due to worsening of HF symptoms. AIMS AND OBJECTIVES To study the effect of Ivabradine in addition to guideline-directed medical therapy (GDMT) in a group of HF patients with HR more than 70 bpm, HF with reduced ejection fraction (HFrEF) left ventricular ejection fraction (LVEF ≤ 40%), and New York Heart Association class II-IV. METHODS The study was conducted at Heart Hospital, Hamad Medical Corporation, Qatar. HF patients with age > 18 years, LVEF ≤40%, on GDMT, and HR of ≥70 bpm were included. The study population was divided into two groups: ivabradine group and non-ivabradine group. The primary outcomes were risk, number and length of hospitalizations due to worsening HF, and cardiovascular mortality. The secondary outcome was all-cause mortality. Baseline characteristics were collected at enrollment. Study outcomes were compared in the two groups by applying Chi-square and Fisher's exact tests. Logistic regression model was applied to assess both hospitalizations and cardiovascular mortality. RESULTS A total of 111 patients were studied, 37 (33.94%) ivabradine group and 74 (66.67%) non-ivabradine group. Risk of hospitalization was lower in Ivabradine group compared to non-Ivabradine group (odds ratio: 0.43, 95% confidence interval [CI]: 0.16-1.015, P = 0.094). Average length of hospitalization in ivabradine and non-ivabradine groups was 12.54 and 8.91 days, respectively (incidence rate ratio [IRR]: 1.63, 95% CI: 0.79-3.38, P = 0.187). Compared to non-ivabradine, ivabradine patients had lower number of hospitalizations (IRR: 1.13, 95% CI: 0.61-2.11, P = 0.694). Death rate in both ivabradine and non-ivabradine groups was 3. CONCLUSIONS Ivabradine along with GDMT reduces the risk of hospitalization due to worsening HF symptoms. Ivabradine had no significant effect on cardiovascular mortality and all-cause mortality. HFrEF non-Arabs patients have lower risk, number and length of hospitalization, and mortality compared to Arabs.

Abstract
The diagnostic challenges associated with type 2 myocardial infarction (T2MI) evolve around an extensive evidence base. T2MI is a type of MI that occurs secondary to ischemia due to increased demand or decreased oxygen supply. This classification has been used for the last 5 years, yet there is little understanding of the characteristics and clinical outcomes. According to a survey, T2M1 can be caused mainly by different factors such as anemia (31%), sepsis (24%), and arrhythmia (17%). Other associated factors, such as age and gender, also play a part in the disease. The pathology behind T2MI is the rise and fall of cardiac troponin values with at least one value above the 99 percentile and evidence of an imbalance unrelated to coronary thrombosis. The diagnosis of the condition is evidence-based backed up with imaging techniques. The treatment of T2MI may involve blood pressure management, administration of blood products, heart rate control, and respiratory support. Depending on the clinical presentation, coronary evaluations can be used to assess the likelihood of coronary artery disease (CAD). If indicated, the MI guidelines may apply to CAD. If it shows, the MI guidelines may use electrocardiography findings of ST-segment elevation myocardial infarction (STEMI) or non-STEMI. However, the absence of CAD indicates that the benefits of cardiovascular risk reduction strategies with T2MI remain uncertain.

[PMID: 34155812 PMCID: PMC8497197 DOI: 10.1002/ehf2.13491] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 05/17/2021] [Accepted: 06/11/2021] [Indexed: 12/21/2022] Open
Abstract
Aims Sacubitril/valsartan significantly reduced heart failure (HF) hospitalization and cardiovascular mortality in a randomized controlled trial. However, little is known about real‐world efficacy and safety of sacubitril/valsartan in Chinese patients with HF with reduced ejection fraction (HFrEF). We aimed to evaluate whether sacubitril/valsartan could improve cardiac function in Chinese patients with HFrEF in a tertiary hospital in China. Methods and results Patients with HFrEF receiving sacubitril/valsartan in our hospital between January 2018 and January 2020 were recruited in the present study. We retrospectively collected and analysed all clinical parameters at baseline and during follow‐up. A total of 100 consecutive patients (73% male) with HFrEF were recruited in the present study. During a median follow‐up period of 365 days [interquartile range (IQR), 346–378], a pronounced improvement of cardiac function was achieved. New York Heart Association classification was significantly improved (P < 0.001), and median N‐terminal pro‐B‐type natriuretic peptides level significantly decreased from 3003 pg/mL (IQR, 1513–5404) to 2039 pg/mL (IQR, 921–3955) (P = 0.010). Mean left ventricular ejection fraction increased from 31 ± 6% to 38 ± 10% (P < 0.001) and median left ventricular end‐diastolic diameter reduced from 63 mm (IQR, 59–67) to 60 mm (IQR, 55–68) (P = 0.001). Mean pulmonary arterial systolic pressure decreased significantly from 49 ± 13 mmHg to 44 ± 12 mmHg (P < 0.001) and median right ventricular end‐diastolic diameter reduced from 23 mm (IQR, 21–26) to 22 mm (IQR, 20–25) (P = 0.030). After treatment with sacubitril/valsartan, mean estimated glomerular filtration rate significantly decreased (from 88.8 ± 22.4 mL/min to 71.8 ± 27.3 mL/min, P < 0.001). Median serum creatinine and median blood urea nitrogen levels significantly increased [from 0.9 mg/dL (IQR, 0.8–1.0) to 1.1 mg/dL (IQR, 0.9–1.3), P < 0.001, and from 6.8 mmol/L (IQR, 5.5–8.9) to 8.0 mmol/L (IQR, 6.6–10.3), P = 0.002, respectively]. The proportion of patients with chronic kidney disease Stage 3/4 increased significantly from 8% to 39% (P < 0.001). Conclusions In Chinese patients with HFrEF, sacubitril/valsartan treatment was associated with a pronounced improvement of cardiac function, but might be prone to a decrease in blood pressure and deterioration in renal function.

Heart failure drug titration, discontinuation, mortality and heart failure hospitalization risk: a multinational observational study (US, UK and Sweden). Eur J Heart Fail 2021; 23:1499-1511.

Abstract
AIMS Use and dosing of guideline-directed medical therapy (GDMT) in patients with heart failure (HF) have been shown to be suboptimal. Among new users of GDMT in HF, we followed the real-life patterns of dose titration and discontinuation of angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), beta-blockers, mineralocorticoid receptor antagonists (MRA) and angiotensin receptor-neprilysin inhibitors (ARNI). METHODS AND RESULTS New users were identified in health care databases in Sweden, UK and US between 2016-2019. Inclusion criterion was a recent HF hospitalization (HHF) triggering the initiation of GDMT. Patients were grouped by GDMT, i.e. ACEi, ARB, beta-blocker, MRA and ARNI, and stratified by initial dose. Follow-up was 12 months, until death or study end. Outcomes were dose titration within each drug class, discontinuation and first HHF or death. Dose/discontinuation follow-up was assessed daily based on the coverage length of a filled prescription and reported on day 365. New users of ACEi (n = 8426), ARB (n = 2303), beta-blockers (n = 10 476), MRA (n = 17 421), and ARNI (n = 29 546) were identified. Over 12 months, target dose achievement was 15%, 10%, 12%, 30%, and discontinuation was 55%, 33%, 24% and 27% for ACEi, ARB, beta-blockers and ARNI, respectively. MRA was rarely titrated and discontinuation rates were high (40%). Event rates for HHF or death ranged from 40.0-86.9 per 100 patient-years across the treatment groups. CONCLUSION Despite high risk of clinical events following HHF, new initiation of GDMT was followed by consistent patterns of low up-titration and early GDMT discontinuation in three countries with different health care and economies. Our data highlight the urgent need for moving away from long sequential approach when initiating HF treatment and for improving just-in-time decision support for patients and health care providers.

Abstract
PURPOSE This study sought to develop models with good identification for adverse outcomes in patients with heart failure (HF) and find strong factors that affect prognosis. PATIENTS AND METHODS A total of 5004 qualifying cases were selected, among which 498 cases had adverse outcomes and 4506 cases were discharged after improvement. The study subjects were hospitalized patients diagnosed with HF from a regional cardiovascular hospital and the cardiology department of a medical university hospital in Shanxi Province of China between January 2014 and June 2019. Synthesizing minority oversampling technology combined with edited nearest neighbors (SMOTE+ENN) was used to pre-process unbalanced data. Traditional logistic regression (LR), k-nearest neighbor (KNN), support vector machine (SVM), random forest (RF), and extreme gradient boosting (XGBoost) were used to build risk identification models, and each model was repeated 100 times. Model discrimination and calibration were estimated using F1-score, the area under the receiver-operating characteristic curve (AUROC), and Brier score. The best performing of the five models was used to identify the risk of adverse outcomes and evaluate the influencing factors. RESULTS The SME-XGBoost was the best performing model with means of F1-score (0.3673, 95% confidence interval [CI]: 0.3633-0.3712), AUC (0.8010, CI: 0.7974-0.8046), and Brier score (0.1769, CI: 0.1748-0.1789). Age, N-terminal pronatriuretic peptide, pulmonary disease, etc. were the most significant factors of adverse outcomes in patients with HF. CONCLUSION The combination of SMOTE+ENN and advanced machine learning methods effectively improved the discrimination efficacy of adverse outcomes in HF patients, accurately stratified patients at risk of adverse outcomes, and found the top factors of adverse outcomes. These models and factors emphasize the importance of health status data in determining adverse outcomes in patients with HF.

Abstract
Diabetes is a very important comorbidity in patients with heart failure. When both diseases coexist cardiovascular morbidity and mortality is greatly increased. Therefore, it is of clinical importance to treat both diseases as early as possible with an optimal therapy. Hitherto, heart failure therapy did not differ if a patient had concomitant diabetes. However, with SGLT-2 inhibitors having demonstrated to reduce hospitalization of heart failure independent of diabetes state and expected to be included into the ESC heart failure treatment guidelines in 2021 coexisting diabetes potentially will make a difference when to start therapy. In this article we provide an overview of current recommendations and also provide clinical considerations for the therapy of heart failure with concomitant diabetes.

Abstract
Objectives: To investigate the effect and mechanism of sacubitril/valsartan on myocardial fibrosis in rats following experimental myocardial infarction and in TGF-β1-treated myocardial fibroblasts. Methods: Male Sprague-Dawley (SD) rats were subjected to coronary artery ligation to establish myocardial infarction and intragastrically fed vehicle, valsartan (Val, 32 mg/kg, once-daily) or sacubitril/valsartan (Sac/Val, 68 mg/kg, once-daily) for 4 weeks. In parallel, myocardial fibroblasts (MFs) isolated from neonatal SD rats were exposed to hypoxia and treated with TGF-β1 (5 ng/ml) plus vehicle, Val (107–10–5 M) or Sac/Val (107–105 M). Rat cardiac function and fibrosis were measured by echocardiography and histological method, respectively. MFs viability and collagen synthesis were determined by cell counting kit-8 and enzyme-linked immunosorbent assay, respectively. Protein expressions of TGF-β1, Smad3, phosphorylated Smad3 (p-Smad3), and p-Smad3 subcellular localization were detected by immunoblotting and immunocytochemistry. Results: Sac/Val significantly improved cardiac structure and function in rats after myocardial infarction, including decreased left ventricular end-diastolic diameter and interventricular septal thickness, increased ejection fraction, and reduced myocardial collagen volume fraction and type Ⅰ and type Ⅲ collagen levels, and this effect was superior to that of Val. Besides, Sac/Val inhibited myocardial TGF-β1 and p-Smad3 protein expression better than Val. Mechanically, Sac/Val significantly attenuated TGF-β1-induced proliferation and collagen synthesis of MFs, and inhibit Smad3 phosphorylation and nucleus translocation, and this effect outperformed Val. Overexpression and silencing of Smad3 enhanced and reversed the inhibitory effects of Sac/Val on TGF-β1-induced collagen synthesis by MFs, respectively. Conclusions: Sacubitril/valsartan improves cardiac function and fibrosis in rats after experimental myocardial infarction, and this effect is related to the inhibition of collagen synthesis in myocardial fibroblasts by inhibiting the TGF/Smads signaling pathway.

Abstract
AIMS In heart failure with reduced ejection fraction (HFrEF), guidelines recommend up-titration of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptors blockers (ARBs) to the maximum tolerated dose. However, some studies suggest that women might need lower doses of ACEi/ARBs than men to achieve similar treatment benefit. METHODS AND RESULTS The HEAAL trial compared low vs. high dose of losartan. We reassessed the efficacy and safety of high- vs. low-dose in men vs. women using Cox models and machine learning algorithms. The mean age was 66 years and 30% of patients were women. Men appeared to have benefited more from high-dose than from low-dose losartan, whereas women appeared to have responded similarly to low and high doses [hazard ratio (95% confidence interval) comparing high- vs. low-dose losartan for the composite outcome of all-cause death or all-cause hospitalization: 0.89 (0.81-0.98) in men and 1.10 (0.95-1.28) in women; interaction P = 0.018]. Female sex clustered along with older age, ischaemic heart failure, New York Heart Association class III/IV, and estimated glomerular filtration rate <60 mL/min. Patients with these features had a poorer response to high-dose losartan. Subgroup analyses supported no benefit from high-dose losartan in patients with poorer kidney function and severe heart failure symptoms. CONCLUSIONS Compared with men, women might need lower doses of losartan to achieve similar treatment benefit. However, beyond sex, other factors (e.g. kidney function, age, and symptoms) may influence the response to high-dose losartan, suggesting that sex-based subgroup findings may be biased by other confounders.

A putative placebo analysis of the effects of sacubitril/valsartan in heart failure across the full range of ejection fraction. Eur Heart J 2021; 41:2356-2362. [PMID: 32221596 PMCID: PMC7327532 DOI: 10.1093/eurheartj/ehaa184] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2020] [Revised: 02/07/2020] [Accepted: 03/27/2020] [Indexed: 12/11/2022] Open
Abstract
Aims The PARADIGM-HF and PARAGON-HF trials tested sacubitril/valsartan against active controls given renin–angiotensin system inhibitors (RASi) are ethically mandated in heart failure (HF) with reduced ejection fraction and are used in the vast majority of patients with HF with preserved ejection fraction. To estimate the effects of sacubitril/valsartan had it been tested against a placebo control, we made indirect comparisons of the effects of sacubitril/valsartan with putative placebos in HF across the full range of left ventricular ejection fraction (LVEF). Methods and results We analysed patient-level data from the PARADIGM-HF and PARAGON-HF trials (n = 13 194) and the CHARM-Alternative and CHARM-Preserved trials (n = 5050, candesartan vs. placebo). The rate ratio (RR) of sacubitril/valsartan vs. putative placebo was estimated by the product of the RR for sacubitril/valsartan vs. RASi and the RR for RASi vs. placebo. Total HF hospitalizations and cardiovascular death were analysed using the negative binomial method. Treatment effects were estimated using cubic spline methods by ejection fraction as a continuous measure. Across the range of LVEF, sacubitril/valsartan was associated with a RR 0.54 [95% confidence interval (CI) 0.45–0.65] for the recurrent primary endpoint compared with putative placebo (P < 0.001). Treatment benefits of sacubitril/valsartan vs. putative placebo varied non-linearly with LVEF with attenuation of effects observed at LVEF above 60%. When analyzing data from PARADIGM-HF and CHARM-Alternative, the estimated risk reduction of sacubitril/valsartan vs. putative placebo was 48% (95% CI 35–58%); P < 0.001. When analyzing data from PARAGON-HF and CHARM-Preserved (with LVEF ≥ 45%), the estimated risk reduction of sacubitril/valsartan vs. putative placebo was 29% (95% CI 7–46%); P = 0.013. Across the full range of LVEF, consistent effects were observed for time-to-first endpoints: first primary endpoint (RR 0.72, 95% CI 0.64–0.82), first HF hospitalization (RR 0.67, 95% CI 0.58–0.78), cardiovascular death (RR 0.76, 95% CI 0.64–0.89), and all-cause death (RR 0.83, 95% CI 0.71–0.96); all P < 0.02. Conclusion This putative placebo analysis reinforces the treatment benefits of sacubitril/valsartan on risk of adverse cardiovascular events across the full range of LVEF, with most pronounced effects observed at a LVEF up to 60%. ![]()

Abstract
Cardiac resynchronization therapy (CRT) is one of the most effective therapies for heart failure with reduced ejection fraction and leads to improved quality of life, reductions in heart failure hospitalization rates and all-cause mortality. Nevertheless, up to two-thirds of eligible patients are not referred for CRT. Furthermore, post-implantation follow-up is often fragmented and suboptimal, hampering the potential maximal treatment effect. This joint position statement from three European Society of Cardiology Associations, Heart Failure Association (HFA), European Heart Rhythm Association (EHRA) and European Association of Cardiovascular Imaging (EACVI), focuses on optimized implementation of CRT. We offer theoretical and practical strategies to achieve more comprehensive CRT referral and post-procedural care by focusing on four actionable domains: (i) overcoming CRT under-utilization, (ii) better understanding of pre-implant characteristics, (iii) abandoning the term 'non-response' and replacing this by the concept of disease modification, and (iv) implementing a dedicated post-implant CRT care pathway.

Abstract
Background and Purpose The profibrotic and proinflammatory effects induced by doxorubicin (DOX) are key processes in the development of serious heart damage. Lack of effective drugs and the unclear mechanisms of its side effects limit the clinical treatment of DOX-induced cardiac injury. This study aimed to explore the protective role of LCZ696 and the potential mechanism of Toll-like receptor 2 (TLR2) in doxorubicin-induced cardiac failure. Experimental Approach DOX (5 mg/kg/week, three times) was used to establish a chronic cardiomyopathy mouse model. Heart function tests, pathology examinations and molecular biology analyses were used to explore the effects of LCZ696 and TLR2 deficiency in vivo and in vitro. Computational docking was applied to predict the key residues for protein-ligand interaction. Key Results The EF% declined, and the LVIDd, pro-fibrosis marker levels and NF-κB related inflammatory response increased in the chronic cardiomyopathy group induced by DOX. LCZ696 treatment and TLR2 deficiency reversed these heart damage in vivo. In H9C2 cells, pre-treatment with LCZ696 and TLR2 knockdown suppressed the DOX-induced high expression of profibrotic and proinflammatory markers. Moreover, DOX notably increased the TLR2-MyD88 interaction in vivo and in vitro, which was inhibited by LCZ696. Finally, we demonstrated the direct interaction between DOX and TLR2 via hydrogen bonds on Pro-681 and Glu-727 and Pro-681 and Ser-704 may be the key residues by which LCZ696 affects the interaction between DOX and TLR2. Conclusion and Implications LCZ696 prevents DOX-induced cardiac dilation failure, fibrosis and inflammation by reducing the formation of TLR2-MyD88 complexes. LZC696 may be a potential effective drug to treat DOX-induced heart failure.

Abstract
AIMS The SMART (Strategic MAnagement to optimize response to cardiac Resynchronization Therapy) Registry was designed to assess real-world outcomes for patients receiving a cardiac resynchronization therapy defibrillator (CRT-D) and to better understand which programming and optimization techniques are used and how effective they are. METHODS AND RESULTS The SMART Registry is a global, multicentre, prospective, observational, post-market CRT-D registry with a planned enrolment of 2000 subjects from a maximum of 200 sites in Europe, North America, and Asia-Pacific region. Each subject will be followed up for a minimum of 12 months. The primary endpoint of CRT response rate at 12 months is defined by a clinical composite score of all-cause mortality, heart failure events, New York Heart Association Class, and quality of life as assessed by a patient global assessment instrument. A subgroup composed of the first 103 consecutive European subjects implanted with an NG4 device will have left ventricular multisite pacing feature enabled at any time during the initial 12 months of follow-up. The primary endpoint for this sub-analysis will be the NG4 PG-related complication-free rate at 36 months. CONCLUSIONS The SMART Registry achieved its recruitment target in August 2019, with 2014 patients enrolled. The baseline demographics demonstrated that patients were generally older, with greater co-morbidity, and on more contemporary medical therapy than in the key CRT trials. The results of the SMART Registry will determine which programming and optimization techniques are effective in this real-world population.

Effects of Sacubitril/Valsartan Treatment on Left Ventricular Myocardial Torsion Mechanics in Patients with Heart Failure Reduced Ejection Fraction 2D Speckle Tracking Echocardiography. J Cardiovasc Echogr 2021; 31:59-67. [PMID: 34485030 PMCID: PMC8388327 DOI: 10.4103/jcecho.jcecho_118_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 02/11/2021] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Left ventricular ejection fraction (LVEF) is calculated from volumetric change without representing true myocardial properties. Strain echocardiography has been used to objectively measure myocardial deformation. Myocardial strain can give accurate information about intrinsic myocardial function, and it can be used to detect early-stage cardiovascular diseases, monitor myocardial changes with specific therapies, differentiate cardiomyopathies, and predict the prognosis of several cardiovascular diseases. Sacubitril/valsartan has been shown to improve mortality and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF). The effect of sacubitril/valsartan angiotensin receptor neprilysin inhibitor (ARNI) on left ventricular (LV) ejection fraction (EF) and torsion dynamics in HFrEF patients has not been previously described. METHODS The study involved 73 patients with HFrEF, for all patients Full history was taken, full clinical examination was done. Baseline vital signs, ECG, NYHA classification, conventional echocardiography and STE were done at baseline study and after 6 and 11 months.Basal and apical LV short-axis images were acquired for further off-line analysis. Using commercially available two-dimensional strain software, apical, basal rotation, and LV torsion were calculated. RESULTS ARNI group of patients showed improvement of symptoms, LV global longitudinal strain (LVGLS)% and diastolic parameters including, E/A, E/e', TV, untwist onset and rate after 6 months of therapy in comparison to the traditionally treated patients. The improvement continued for 11 months with in additional significant improvement of systolic parameters in the form of LVGLS%, EF%, Twist, Apical and basal rotations, main dependent parameters for improvement of EF% was LVGLS% and Apical rotation. CONCLUSION To the best of our knowledge, this is the first study to demonstrate that therapy with sacubitril/valsartan in HFrEF patients could create a state of gradual and chronic LV deloading which cause relieving of myocardial wall tensions and decreasing the LV end diastolic pressure this state could cause cardiac reverse remodeling and reestablishment of starling forces proprieties of LV myocardium, which lead to increase of LV EF.

Abstract
BACKGROUND AND AIMS The coprescription of an angiotensin-converting enzyme inhibitor (ACEi) with clopidogrel reportedly increases bleeding risk. However, studies have not described such an increase in cases of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). METHODS We analyzed electronic medical records of patients with discharge records of having undergone DAPT after PCI from a national health insurance claims database for January 1, 2006 to December 31, 2014. The date of PCI was the index date, and the primary outcome was major bleeding. The unit of analysis was one person-quarter. We compared patients who were prescribed with those not prescribed an ACEi in the cohort. A Poisson model with inverse probability of treatment weighting was fitted using generalized estimating equations to measure the risk of outcomes. RESULTS In total, 193,258 patients underwent DAPT after PCI; 46% had a coprescription of an ACEi. After screening, 170,775 patients (479,263 person-quarters) remained for analysis. The mean patient age was 65 ± 13 years, and 73.43% were men. In total, 79,739 prescriptions of an ACEi were written: 57%, 14.21%, 8.88%, 7.17%, and 4.68% were for captopril, ramipril, enalapril, perindopril, and imidapril, respectively. A concomitant prescription of an ACEi with clopidogrel was not associated with increased bleeding risk (adjusted rate ratio: 1.08, 99% confidence interval: 0.99-1.17). CONCLUSIONS The coadministration of an ACEi with clopidogrel after PCI is common. In this real-world cohort study, such coadministration was not associated with an increased risk of major bleeding in patients undergoing DAPT after PCI.

Abstract
The HER2 receptor (Human Epidermal Growth Receptor 2) is a transmembrane receptor with tyrosine kinase activity that is over-expressed in 25-30 % of breast carcinomas. Its activation is associated with an exaggeration of cell proliferation with an increase in repair capacity resulting in increased radioresistance. On cardiac tissues, HER2 receptor activation plays a cardio-protective role. Trastuzumab, the first anti-HER2 drug used to treat patients with breast cancer overexpressing HER2 receptor , inhibits the cascade of reactions resulting in the proliferation of tumor cells, thus restoring cellular radiosensitivity. However, the combination of Trastuzumab with radiation therapy also removes HER2 receptor cardio-protective role on myocardial cells which increases the risk of cardiotoxicity. Thus, the concomitant association of these two modalities has long been a subject of controversy. Recent advances in radiation therapy technology and early detection of cardiac injury may limit the cardiotoxicity of this combination. Through this review, we developed the biological basis and the benefit-risk of concomitant combination of radiotherapy and Trastuzumab in adjuvant treatment of breast cancers overexpressing HER2 and we discuss the modalities of its optimization.

Abstract
The treatment with sacubitril/valsartan in patients suffering from chronic heart failure with reduced ejection fraction increases left ventricular ejection fraction and decreases the risk of sudden cardiac death. We conducted a retrospective analysis regarding the impact of age differences on the treatment outcome of sacubitril/valsartan in patients with chronic heart failure with reduced ejection fraction. Patients were defined as adults if ≤65 years (n = 51) and older if >65 years of age (n = 76). The incidence of ventricular arrhythmias at 1-year follow-up was comparable in both groups (30.8 vs 26.5%; p = 0.71). The mortality rate in adult patients is significantly lower as compared with older patients (2 vs 14.5%; log-rank = 0.04). Older patients may suffer remarkably more side effects than adult patients (21.1 vs 11.8%; p = 0.03).
