Therapy duration and improvement of ventricular function in de novo heart failure: the Heart Failure Optimization study. Eur Heart J 2024; 45:2771-2781. [PMID: 38864173 PMCID: PMC11313580 DOI: 10.1093/eurheartj/ehae334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 04/30/2024] [Accepted: 05/15/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND AND AIMS In patients with de novo heart failure with reduced ejection fraction (HFrEF), improvement of left ventricular ejection fraction (LVEF) is expected to occur when started on guideline-recommended medical therapy. However, improvement may not be completed within 90 days. METHODS Patients with HFrEF and LVEF ≤ 35% prescribed a wearable cardioverter-defibrillator between 2017 and 2022 from 68 sites were enrolled, starting with a registry phase for 3 months and followed by a study phase up to 1 year. The primary endpoints were LVEF improvement > 35% between Days 90 and 180 following guideline-recommended medical therapy initiation and the percentage of target dose reached at Days 90 and 180. RESULTS A total of 598 patients with de novo HFrEF [59 years (interquartile range 51-68), 27% female] entered the study phase. During the first 180 days, a significant increase in dosage of beta-blockers, renin-angiotensin system inhibitors, and mineralocorticoid receptor antagonists was observed (P < .001). At Day 90, 46% [95% confidence interval (CI) 41%-50%] of study phase patients had LVEF improvement > 35%; 46% (95% CI 40%-52%) of those with persistently low LVEF at Day 90 had LVEF improvement > 35% by Day 180, increasing the total rate of improvement > 35% to 68% (95% CI 63%-72%). In 392 patients followed for 360 days, improvement > 35% was observed in 77% (95% CI 72%-81%) of the patients. Until Day 90, sustained ventricular tachyarrhythmias were observed in 24 wearable cardioverter-defibrillator carriers (1.8%). After 90 days, no sustained ventricular tachyarrhythmia occurred in wearable cardioverter-defibrillator carriers. CONCLUSIONS Continuous optimization of guideline-recommended medical therapy for at least 180 days in HFrEF is associated with additional LVEF improvement > 35%, allowing for better decision-making regarding preventive implantable cardioverter-defibrillator therapy.

Clinical characteristics, treatment, trajectories and outcome of patients with dilated cardiomyopathy in a national heart failure registry. Int J Cardiol 2024; 407:131986. [PMID: 38513737 DOI: 10.1016/j.ijcard.2024.131986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 02/23/2024] [Accepted: 03/17/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND Available data on the clinical characteristics and prognosis of patients with heart failure (HF) due to dilated cardiomyopathy (DCM) derive mainly from tertiary care centres for cardiomyopathies or from drug trial sub-studies, which may entail a referral bias. METHODS From 2008 to 2021, we enrolled in a nationwide HF Registry 1886 DCM patients and 3899 with ischemic heart disease (IHD). RESULTS Patients with DCM were younger, more often female, had more commonly recent onset HF, left bundle branch block, and showed higher LV end-diastolic volume and lower LVEF than IHD. With respect to IHD, DCM patients received more often mineralocorticoid receptor antagonists, renin angiotensin system inhibitors and betablockers, the latter more commonly at doses ≥50% of target, and triple guideline-directed medical therapy (GDMT) (adjusted OR 1.411, 95% CI 1.247-1.595, p < .0001). During one-year follow-up, 819 patients (14.2%) died or were hospitalized for HF [187 (9.9%) DCM, 632 (16.2%) IHD]; DCM was associated with lower risk of the combined end-point (adjusted HR 0.745, 95% CI 0.625- 0.888, p = .0011). Among the 1954 patients with 1-year echocardiograms available, 1483 had LVEF≤40% at baseline; of these,166 (30.6%) DCM and 165 (17.5%) IHD improved their LVEF to >40% (p < .0001). DCM aetiology was associated with higher likelihood of LVEF improvement (adjusted OR 1.722, 95% CI 1.328 -2.233, p < .0001). CONCLUSIONS DCM patients have a different clinical profile, greater uptake of GDMT and better outcomes than IHD subjects. A comprehensive management approach is needed to further address the risk of unfavorable outcomes in DCM.

Abstract
Currently, the fully magnetically levitated left ventricular assist device (LVAD) HeartMate 3 (HM3) is the only commercially available device for advanced heart failure (HF) patients. However, the left ventricular (LV) functional and structural changes following mechanical unloading and circulatory support (MCS) with the HM3 have not been investigated. We compared the reverse remodeling induced by the HM3 to older generation continuous-flow LVADs. Chronic HF patients (n = 405) undergoing MCS with HeartWare Ventricular Assist Device (HVAD, n = 115), HM3 (n = 186), and HeartMate II (HM2, n = 104) at four programs were included. Echocardiograms were obtained preimplant and at 1, 3, 6, and 12 months following LVAD implantation. There were no differences in the postimplant serial LV ejection fraction (LVEF) between the devices. The postimplant LV internal diastolic diameter (LVIDd) was significantly lower for HM2 at 3 and 6 months compared with HVAD and HM3. The proportion of patients achieving "cardiac reverse remodeling responder" status (defined as LVEF improvement to ≥40% and LVIDD ≤5.9 cm) was 11.9%, and was similar between devices. HeartMate 3 appears to result in similar cardiac reverse remodeling as older generation CF-LVADs, suggesting that the fully magnetically levitated device technology could provide an effective platform to further study and promote cardiac reverse remodeling.

Clinical Characterization of Arrhythmia-Induced Cardiomyopathy in Patients With Tachyarrhythmia and Idiopathic Heart Failure. JACC Clin Electrophysiol 2024; 10:870-881.

Abstract
BACKGROUND Arrhythmia-induced cardiomyopathy (AIC) is a known entity, but prospective evidence for its characterization is limited. OBJECTIVES This study aimed to: 1) determine the relative frequency of the pure form of AIC in the clinically relevant cohort of patients with newly diagnosed, otherwise unexplained left ventricular systolic dysfunction (LVSD) and tachyarrhythmia; 2) assess the time to recovery from LVSD; and 3) identify parameters for an early diagnosis of AIC. METHODS Patients were prospectively included, underwent effective rhythm restoration, and were followed-up at 2, 4, and 6 months to evaluate clinical characteristics, biomarkers, and cardiac imaging including cardiac magnetic resonance imaging. Patients with recurred arrhythmia were excluded from analysis. RESULTS 41 of 50 patients were diagnosed with AIC 6 months after rhythm restoration. Left ventricular (LV) ejection fraction increased 2 months after rhythm restoration from 35.4% ± 8.2% to 52.7% ± 8.0% in AIC patients vs 37.0% ± 9.5% to 43.3% ± 7.0% in non-AIC patients. From month 2 to 6, LV ejection fraction continued to increase in AIC patients (57.2% ± 6.1%; P < 0.001) but remained stable in non-AIC patients (44.0% ± 7.8%; P = 0.628). Multivariable logistic regression analysis revealed that lower LV end-diastolic diameter at baseline could be used for early diagnosis of AIC, whereas biomarkers and other morphological or functional parameters, including late LV gadolinium enhancement, did not show suitability for early diagnosis. CONCLUSIONS We observed a high prevalence of AIC in patients with otherwise unexplained LVSD and concomitant tachyarrhythmia, suggesting that this condition may be underdiagnosed in clinical practice. Most patients recovered fast, within months, from LVSD. A low initial LV end-diastolic diameter may constitute an early marker for diagnosis of AIC.

Abstract
AIMS The trajectories of systolic function after admission for acute heart failure (HF) and their effect on clinical outcomes have not been fully elucidated. We aimed to assess changes in left ventricular ejection fraction (LVEF) between the index and 1 year after discharge and to examine their prognostic implications. METHODS AND RESULTS We extracted data from a prospective multicentre registry of patients hospitalized for acute HF and identified 1636 patients with LVEF data at admission and 1 year after discharge. We categorized them into five groups based on LVEF changes: HF with unchanged-preserved EF [HFunc-pEF (EF ≥ 50%); N = 527, 32.2%], unchanged-mildly reduced EF [HFunc-mrEF (EF 41-49%); N = 86, 5.3%], unchanged-reduced EF [HFunc-rEF (EF ≤ 40%); N = 377, 23.0%], worsened EF (HFworEF; N = 83, 5.1%), and improved EF (HFimpEF; N = 563, 34.4%). We then evaluated the subsequent composite outcome of cardiovascular death and HF readmission. During 1 year after discharge, 53% of patients with HF with reduced EF and 67% of those with HF with mildly reduced EF (HFmrEF) transitioned to other categories, whereas 92% of those with HF with preserved EF (HFpEF) remained within the same category. Patients with HFimpEF were more likely to be younger and had relatively preserved renal function, whereas those with HFworEF were the oldest and had more comorbidities among the five groups. After multivariable adjustment, patients with HFimpEF and HFunc-pEF had a lower risk for composite outcomes when referenced to patients with HFunc-rEF [hazard ratio (95% confidence interval), P-value: 0.28 (0.16-0.49), P < 0.001, and 0.40 (0.25-0.63), P < 0.001, respectively]. Conversely, patients with HFunc-mrEF and HFworEF had a comparable risk [0.44 (0.18-1.07), P = 0.07, and 0.63 (0.29-1.39), P = 0.26, respectively]. CONCLUSIONS A substantial number of patients with HF experienced transitions to other categories after discharge. Notably, patients with decreased EF experienced a worse prognosis, even with slight decreases (e.g. HFpEF transitioning to HFmrEF). These findings emphasize the significance of longitudinal assessments of systolic function to better manage patients following acute decompensation.

Predictors and prognostic implications of left ventricular ejection fraction trajectory improvement in the spectrum of heart failure with reduced and mildly reduced ejection fraction. J Cardiol 2024; 83:250-257. [PMID: 37802201 DOI: 10.1016/j.jjcc.2023.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 09/11/2023] [Accepted: 09/28/2023] [Indexed: 10/08/2023]
Abstract
BACKGROUND The latest guidelines emphasize the significance of evaluating the left ventricular ejection fraction (LVEF) trajectory in patients with heart failure (HF). Because patients with HF with reduced ejection fraction (HFrEF) and HF with mildly reduced ejection fraction (HFmrEF) have reduction in systolic function, they might be in a trajectory of LVEF improvement after medical and device-based therapies. While previous studies have primarily focused on LVEF improvement in HFrEF, there is limited research on LVEF trajectory improvement across the spectrum of HFrEF and HFmrEF. This study aimed to assess the determinants and prognostic implications of LVEF trajectory improvement in HFrEF and HFmrEF patients. METHODS The cohort was classified into the improved group (HFrEF-to-HF with improved ejection fraction (HFimpEF) and HFmrEF-to-HF with preserved ejection fraction (HFpEF)) and the unimproved group (lack of improved group criteria). The primary endpoints were the composite of all-cause mortality or HF hospitalization, all-cause mortality, and HF hospitalization. Predictors of LVEF trajectory improvement were also evaluated. RESULTS A total 1303 patients were included in the study (improved/unimproved group: n = 497/806). Cox regression analysis showed that the improved group experienced lower risks of prespecified end points than the unimproved group. Multivariate logistic regression analysis showed that atrial flutter, use of spironolactone, and treatment with catheter ablation were associated with LVEF trajectory improvement, while myocardial infarction, prior percutaneous catheter intervention or coronary artery bypass graft, E/e', and left ventricular end-diastolic diameter were identified as negative predictors of LVEF trajectory improvement. In the improved subgroup, the prognosis for the HFrEF-to-HFimpEF and HFmrEF-to-HFpEF was comparable. CONCLUSIONS LVEF trajectory improvement patients had improved clinical outcomes and it was associated with important clinical, baseline cardiac structure and function, and treatment factors. Outcomes were similar in both HFrEF-to-HFimpEF and HFmrEF-to-HFpEF subgroups. These results suggest that emphasis should be placed on LVEF trajectory improvement to improve the outcomes of this population.

Abstract
Objectives There are many available pharmaceutical and surgical management for Coronary artery disease (CAD) patients. However, coronary artery bypass grafting (CABG) is the preferred treatment modality for CAD patients with low ejection fraction (EF) in view of the more favorable outcomes. This study aimed to determine the associated factors of poor outcomes post-CABG for heart failure patients with reduced left ventricular ejection fraction who underwent on-pump and off-pump CABG. Methods A retrospective review of CAD patients who underwent isolated on-pump CABG (ONCAB) or off-pump CABG (OPCAB) in Beijing Anzhen Hospital Affiliated with Capital Medical University from January 2013 to March 2021. Only those with confirmed reduced left ventricular ejection fraction (LVEF) ≤40% on preoperative echocardiography were included. By analyzing the clinical and surgical data, postoperative mortality and morbidity, as well as major cardiovascular and cerebrovascular adverse events (MACCE) as endpoints, certain risk factors of the postoperative complications were identified. Results Out of the 500 patients, 64 developed MACCE, of which 14 (13.6%) occurred in the ONCAB group and 50 (14.0%) in the OPCAB group. Univariate COX regression analysis showed that age ≥65 years, history of diabetes, and preoperative renal insufficiency were independent risk factors for postoperative primary endpoint events in CAD patients with heart failure with reduced ejection fraction (HFrEF). Following the multivariate COX regression analysis, in addition to the above three risk factors, a history of previous percutaneous coronary angiography (PCI) intervention was also a risk factor for the occurrence of the primary endpoints post-CABG. Conclusion Based on the analysis, significant predictors of post-CABG MACCE in patients with HFrEF included being older than 65 years old, having diabetes, preoperative renal insufficiency, and having previous PCI.

Abstract
BACKGROUND Obesity leads to an increased risk of cardiovascular disease morbidity and death, including heart failure. Bariatric surgery has been proven to be the most effective long-term weight management treatment. This study investigated the changes in cardiac structure and function after bariatric surgery, including left ventricular global longitudinal strain. METHODS AND RESULTS There were 398 consecutive patients who underwent bariatric surgery with pre- and postoperative transthoracic echocardiographic imaging at a US health system between 2004 and 2019. We compared cardiovascular risk factors and echocardiographic parameters between baseline and follow-up at least 6 months postoperatively. Along with decreases in weight postoperatively, there were significant improvements in cardiovascular risk factors, including reduction in systolic blood pressure levels from 132 mm Hg (25th-75th percentile: 120-148 mm Hg) to 127 mm Hg (115-140 mm Hg; P=0.003), glycated hemoglobin levels from 6.5% (5.9%-7.6%) to 5.7% (5.4%-6.3%; P<0.001), and low-density lipoprotein levels from 97 mg/dL (74-121 mg/dL) to 86 mg/dL (63-106 mg/dL; P<0.001). Left ventricular mass decreased from 205 g (165-261 g) to 190 g (151-236 g; P<0.001), left ventricular ejection fraction increased from 58% (55%-61%) to 60% (55%-64%; P<0.001), and left ventricular global longitudinal strain improved from -15.7% (-14.3% to -17.5%) to -18.6% (-16.0% to -20.3%; P<0.001) postoperatively. CONCLUSIONS This study has shown the long-term impact of bariatric surgery on cardiac structure and function, with reductions in left ventricular mass and improvement in left ventricular global longitudinal strain. These findings support the cardiovascular benefits of bariatric surgery.

Clinical outcomes and predictors of delayed echocardiographic response to cardiac resynchronization therapy. J Cardiovasc Electrophysiol 2024; 35:97-110. [PMID: 37897084 DOI: 10.1111/jce.16125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 10/17/2023] [Accepted: 10/26/2023] [Indexed: 10/29/2023]
Abstract
INTRODUCTION The clinical outcomes and mechanisms of delayed responses to cardiac resynchronization therapy (CRT) remain unclear. We aimed to investigate the differences in outcomes and gain insight into the mechanisms of early and delayed responses to CRT. METHODS This retrospective study included 110 patients who underwent CRT implantation. Positive response to CRT was defined as ≥15% reduction of left ventricular (LV) end-systolic volume on echocardiography at 1 year (early phase) and 3 years (delayed phase) after implantation. The latest mechanical activation site (LMAS) of the LV was identified using two-dimensional speckle-tracking radial strain analysis. RESULTS Seventy-eight (71%) patients exhibited an early response 1 year after CRT implantation. Of 32 non-responders in the early phase, 12 (38%) demonstrated a delayed response, and 20 (62%) were classified as non-responders after 3 years. During the follow-up time of 10.3 ± 0.5 years, the delayed and early responders had a similar prognosis of mortality and heart failure (HF) hospitalization. In contrast, non-responders had a worse prognosis. Multivariate analysis revealed that a longer duration (months) between initial HF hospitalization and CRT (odds ratio [OR]: 1.126; 95% confidence interval [CI]: 1.036-1.222; p = .005), non-exact concordance of LV lead location with LMAS (OR: 32.744; 95% CI: 1.101-973.518; p = .044), and pre-QRS duration (OR: 0.901; 95% CI: 0.827-0.981; p = .016) were independent predictors of delayed response to CRT compared with early response. CONCLUSION The prognoses were similar regardless of the response time after CRT. A longer history of HF, suboptimal LV lead position, and shorter pre-QRS duration were related to delayed response than early response.

Abstract
PURPOSE OF REVIEW With the widespread implementation of contemporary disease-modifying heart failure therapy, the rates of normalization of ejection fraction are continuously increasing. The TRED-HF trial confirmed that heart failure remission rather than complete recovery is typical in patients with dilated cardiomyopathy who respond to therapy. The present review outlines key points related to the management and knowledge gaps of this growing patient group, focusing on patients with non-ischaemic dilated cardiomyopathy. RECENT FINDINGS There is substantial heterogeneity among patients with normalized ejection fraction. The specific etiology is likely to affect the outcome, although a multiple-hit phenotype is frequent and may not be identified without comprehensive characterization. A monogenic or polygenic genetic susceptibility is common. Ongoing pathophysiological processes may be unraveled with advanced cardiac imaging, biomarkers, multi-omics, and machine learning technologies. There are limited studies that have investigated the withdrawal of specific heart failure therapies in these patients. Diuretics may be safely withdrawn if there is no evidence of congestion, while continued therapy with at least some disease-modifying therapy is likely to be required to reduce myocardial workload and sustain remission for the vast majority. Understanding the underlying disease mechanisms of patients with normalized ejection fraction is crucial in identifying markers of myocardial relapse and guiding individualized therapy in the future. Ongoing clinical trials should inform personalized approaches to therapy.

Abstract
Patients with persistent heart failure (HF) with reduced ejection fraction (HFrEF) have a poorer prognosis than those with HF with improved ejection fraction (HFimpEF). However, data on the predictive value of echocardiographic parameters for persistent HFrEF are lacking. We retrospectively studied 443 patients who were diagnosed with HFrEF (EF ≤ 40%) during hospitalization and underwent echocardiography at the 1-year follow-up. We divided them into the 2 groups: HFimpEF (EF > 40%) and persistent HFrEF group at 1-year follow-up, and assessed the predictive value of echocardiographic parameters at discharge for persistent HFrEF. In total, 301/443 patients (68%) were diagnosed with persistent HFrEF and 142/443 (32%) with HFimpEF at the 1-year follow-up. Kaplan-Meier analysis revealed that the persistent HFrEF group had a poorer prognosis than the HFimpEF group (log-rank, P < 0.001). Receiver operating characteristic curve analysis revealed that left ventricular end-systolic diameter (LVESD) had the highest area under the curve (AUC) (0.70; 95% confidence interval [CI]: 0.64-0.75; cutoff value: 55 mm) among various echocardiographic parameters. LVESD was an independent predictor of persistent HFrEF at the 1-year follow-up (odds ratio: 1.07, 95%CI: 1.02-1.12) upon multivariable logistic regression analysis. The incidence of persistent HFrEF was higher in patients with an LVESD ≥ 55 mm than in those with an LVESD < 55 mm (81% versus 55%, Fisher's exact test, P < 0.001). In conclusion, an LVESD (≥ 55 mm) was associated with persistent HFrEF. Focusing on LVESD in daily practice may help clinicians with risk stratification for decision-making regarding management in patients with advanced HF refractory to guideline-directed medical therapy.

Abstract
Cardiomyocytes in the adult human heart show a regenerative capacity, with an annual renewal rate around 0.5%. Whether this regenerative capacity of human cardiomyocytes is employed in heart failure has been controversial. Using retrospective 14C birth dating we analyzed cardiomyocyte renewal in patients with end-stage heart failure. We show that cardiomyocyte generation is minimal in end-stage heart failure patients at rates 18-50 times lower compared to the healthy heart. However, patients receiving left ventricle support device therapy, who showed significant functional and structural cardiac improvement, had a >6-fold increase in cardiomyocyte renewal relative to the healthy heart. Our findings reveal a substantial cardiomyocyte regeneration potential in human heart disease, which could be exploited therapeutically.

The feasibility and safety of his-purkinje conduction system pacing in patients with heart failure with severely reduced ejection fraction. Front Cardiovasc Med 2023; 10:1187169. [PMID: 37283576 PMCID: PMC10239933 DOI: 10.3389/fcvm.2023.1187169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 05/05/2023] [Indexed: 06/08/2023] Open
Abstract
Objective The purpose of this study was to evaluate the feasibility and outcomes of conduction system pacing (CSP) in patients with heart failure (HF) who had a severely reduced left ventricular ejection fraction (LVEF) of less than 30% (HFsrEF). Methods Between January 2018 and December 2020, all consecutive HF patients with LVEF < 30% who underwent CSP at our center were evaluated. Clinical outcomes and echocardiographic data [LVEF and left ventricular end-systolic volume (LVESV)], and complications were all recorded. In addition, clinical and echocardiographic (≥5% improvement in LVEF or ≥15% decrease in LVESV) responses were assessed. The patients were classified into a complete left bundle branch block (CLBBB) morphology group and a non-CLBBB morphology group according to the baseline QRS configuration. Results Seventy patients (66 ± 8.84 years; 55.7% male) with a mean LVEF of 23.2 ± 3.23%, LVEDd of 67.33 ± 7.47 mm and LVESV of 212.08 ± 39.74 ml were included. QRS configuration at baseline was CLBBB in 67.1% (47/70) of patients and non-CLBBB in 32.9%. At implantation, the CSP threshold was 0.6 ± 0.3 V @ 0.4 ms and remained stable during a mean follow-up of 23.43 ± 11.44 months. CSP resulted in significant LVEF improvement from 23.2 ± 3.23% to 34.93 ± 10.34% (P < 0.001) and significant QRS narrowing from 154.99 ± 34.42 to 130.81 ± 25.18 ms (P < 0.001). Clinical and echocardiographic responses were observed in 91.4% (64/70) and 77.1% (54/70) of patients. Super-response to CSP (≥15% improvement in LVEF or ≥30% decrease in LVESV) was observed in 52.9% (37/70) of patients. One patient died due to acute HF and following severe metabolic disorders. Baseline BNP (odds ratio: 0.969; 95% confidence interval: 0.939-0.989; P = 0.045) was associated with echocardiographic response. The proportions of clinical and echocardiographic responses in the CLBBB group were higher than those in the non-CLBBB group but without significant statistical differences. Conclusions CSP is feasible and safe in patients with HFsrEF. CSP is associated with a significant improvement in clinical and echocardiographic outcomes, even for patients with non-CLBBB widened QRS.

Abstract
Sacubitril/valsartan has a noteworthy advantage in improving ventricular remodelling, as well as reducing cardiovascular mortality and the rate of heart failure (HF) readmission. However, clinically, some patients with HF still have low sensitivity to sacubitril/valsartan, indicating sacubitril/valsartan resistance (SVR). A total of 46 patients with HF after AMI (23 SVR and 23 non-sacubitril/valsartan resistance (NSVR)) were selected. Five SVR and 5 matched NSVR samples were screened for differentially expressed ncRNAs along with mRNAs. A total of 124 differentially expressed miRNAs, 137 circRNAs, 237 lncRNAs and 50 mRNAs were screened by RNA sequencing technology. After quantitative real-time PCR (qRT‒PCR) verification of selected biomarkers in 18 pairs of samples, we found that for patients with SVR, hsa-miR-543, hsa-miR-642b-5p, hsa-miR-760, hsa_circ_0137499, ENST00000474394, ENST00000528337, E2F1, NEAT1, and YTHDF2 were upregulated, and hsa-miR-424-5p, hsa-miR-21-3p, hsa_circRNA_0003275, hsa_circRNA_0004494, hsa_circ_0093522, ENST00000467951, ENST00000558177, ACTA2, ANPEP, and CAMP were downregulated. Then, with the help of our constructed ceRNA network and functional annotation enrichment, we speculated that inflammatory pathways (such as the apelin signalling pathway) and lipid metabolism pathways (such as fatty acid metabolism) may be involved in the regulation of SVR. These discoveries lay a foundation for further mechanistic research and provide a direction for individualized drug administration.

ESC Heart Fail 2023; 10:1358-1371. [PMID: 36732921 PMCID: PMC10053299 DOI: 10.1002/ehf2.14303] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 11/09/2022] [Accepted: 01/09/2023] [Indexed: 02/04/2023] Open
Abstract
AIMS This study aimed to investigate the prognostic value of dynamic changes in left ventricular ejection fraction (EF) for cardiovascular (CV) outcomes in an all-comer heart failure (HF) population with reduced EF (HFrEF, EF < 40%). We sought to identify independent factors related to improvement in EF and to identify risk factors for increased risk of CV events in the subgroups of improved EF (iEF) and non-improved EF (niEF), respecively. METHODS AND RESULTS This is a retrospective sub-analysis from the REDEAL HF trial, which included consecutive patients with chronic HF who were hospitalized from July 2009 to December 2017. Baseline and follow-up echocardiography data (interval ≥12 months) of 573 consecutive patients with HFrEF were analysed. iEF was defined as absolute improvement in EF ≥ 10% and follow-up EF over 40%. The primary endpoint was defined as a composite endpoint of cardiovascular (CV) death, CV hospitalization, or appropriate implantable cardioverter-defibrillator (ICD) therapy for ventricular arrhythmia. EF improved in 37.2% of patients with HFrEF during follow-up (median period of 17 months). iEF was independently associated with shorter HF duration (>4 vs. ≤4 years, odd ratio [OR] = 0.477, 95% CI 0.305-0.745), no coronary artery disease (CAD vs. no CAD, OR = 0.583, 95% CI 0.396-0.858), and no ICD implantation (ICD vs. no ICD, OR = 0.341, 95% CI 0.228-0.511). Compared with niEF, iEF was significantly and independently associated with lower all-cause mortality (22.1% vs. 31.1%, P = 0.019; hazard ratio [HR] = 0.674, 95% CI 0.469-0.968), lower CV mortality (8.9% vs. 16.1%, P = 0.015; HR = 0.539, 95% CI 0.317-0.916), and lower CV events risk (27.2% vs. 49.2%, P < 0.001; HR 0.519, 95% CI 0.381-0.708), after adjustment for age, sex, duration of HF, and other clinical risk factors. Hypertension (HR = 2.452, P = 0.032) and elevated N-terminal prohormone of brain natriuretic peptide (NT-proBNP >1153 pg/mL, HR = 4.372, P < 0.001) were identified as independent risk factors for CV events in the iEF subgroup. ICD implantation (HR = 1.533, P = 0.011), elevated NT-proBNP (HR = 1.626, P = 0.018), increased left atrial volume index (HR = 1.461, P = 0.021), reduced lateral mitral annular plane systolic excursion (HR = 1.478, P = 0.025), and reduced tricuspid plane systolic excursion (HR = 1.491, P = 0.039) were identified as risk factors for CV events in the niEF subgroup. CONCLUSIONS Improvement in EF is independently related to the longer survival and lower CV related mortality and hospitalization rate of HFrEF. Elevated baseline NT-proBNP is identified as the strongest prognostic factor associated with increased CV events risk in HFrEF patients both with and without improved EF, regardless of age, sex, duration of HF, and other clinical risk factors.

[PMID: 36349244 PMCID: PMC9637339 DOI: 10.2147/jmdh.s381028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/13/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose E-OJ-01 (OxyjunTM), a proprietary, standardized aqueous extract of Terminalia arjuna (TA) bark, has previously shown promising cardiovascular health benefits in healthy young athletic adults and is now being tested to determine its ability to support left ventricular ejection fraction and associated parameters in a diverse population. Participants and Methods Healthy adults aged 30-70 years (n=72) were included in the study to investigate the effect of 400 mg/day of E-OJ-01 when administered for 8 weeks on myocardial pumping capacity, primarily left ventricular ejection fraction (LVEF). The secondary endpoints were improvement in diastolic filling (E/A) ratio, rate pressure product (RPP), and fatigue severity scale (FSS) score. The effect of the intervention on blood lipids and gamma-glutamyltransferase (GGT) levels was also explored. The safety of the intervention was evaluated by monitoring adverse events, vitals (heart rate (HR), blood pressure (BP), and body temperature (BT)), and liver (serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT)) and kidney function (serum creatinine). Results E-OJ-01 increased the LVEF by 6.28% (percentage change) from the baseline compared with 0.24% (percentage change) in the placebo group (p<0.05). It reduced fatigue (22.52%), RPP (1.54%), and GGT levels (5.90%) from the baseline. No adverse events related to the intervention were observed during the study. Conclusion The study showed that E-OJ-01 could improve cardiac pumping capacity by significantly increasing LVEF and reducing fatigue in a diverse, healthy population.

Transfer RNA-derived small RNAs and their potential roles in the therapeutic heterogeneity of sacubitril/valsartan in heart failure patients after acute myocardial infarction. Front Cardiovasc Med 2022; 9:961700. [PMID: 36247465 PMCID: PMC9558900 DOI: 10.3389/fcvm.2022.961700] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Accepted: 09/14/2022] [Indexed: 12/05/2022] Open
Abstract
BackgroundIt has been reported that sacubitril/valsartan can improve cardiac function in acute myocardial infarction (AMI) patients complicated by heart failure (HF). However, a number of patients cannot be treated successfully; this phenomenon is called sacubitril/valsartan resistance (SVR), and the mechanisms remain unclear.MethodsIn our present research, the expression profiles of transfer RNA (tRNA)-derived small RNAs (tsRNAs) in SVR along with no sacubitril/valsartan resistance (NSVR) patients were determined by RNA sequencing. Through bioinformatics, quantitative real-time PCR (qRT-PCR), and cell-based experiments, we identified SVR-related tsRNAs and confirmed their diagnostic value, predicted their targeted genes, and explored the enriched signal pathways as well as regulatory roles of tsRNAs in SVR.ResultsOur research indicated that 36 tsRNAs were upregulated and that 21 tsRNAs were downregulated in SVR. Among these tsRNAs, the expression of tRF-59:76-Tyr-GTA-2-M3 and tRF-60:76-Val-AAC-1-M5 was upregulated, while the expression of tRF-1:29-Gly-GCC-1 was downregulated in the group of SVR. Receiver operating characteristic (ROC) curve analysis demonstrated that these three tsRNAs were potential biomarkers of the therapeutic heterogeneity of sacubitril/valsartan. Moreover, tRF-60:76-Val-AAC-1-M5 might target Tnfrsf10b and Bcl2l1 to influence the observed therapeutic heterogeneity through the lipid and atherosclerosis signaling pathways.ConclusionHence, tsRNA might play a vital role in SVR. These discoveries provide new insights for the mechanistic investigation of responsiveness to sacubitril/valsartan.

Smaller left ventricular end-systolic diameter and lower ejection fraction at baseline associated with greater ejection fraction improvement after revascularization among patients with left ventricular dysfunction. Front Cardiovasc Med 2022; 9:967039. [PMID: 36247459 PMCID: PMC9559822 DOI: 10.3389/fcvm.2022.967039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 09/13/2022] [Indexed: 11/25/2022] Open
Abstract
Objectives To investigate the predictive roles of pre-operative left ventricular (LV) size and ejection fraction (EF) in EF improvement and outcome following revascularization in patients with coronary artery disease (CAD) and LV dysfunction. Background Revascularization may improve EF and long-term outcomes of patients with LV dysfunction. However, the determinants of EF improvement have not yet been investigated comprehensively. Materials and methods Patients with EF measurements before and 3 months after revascularization were enrolled in a cohort study (No. ChiCTR2100044378). All patients had baseline EF ≤ 40%. EF improvement was defined as absolute increase in EF > 5%. According to LV end-systolic diameter (LVESD) (severely enlarged or not) and EF (≤35% or of 36–40%) at baseline, patients were categorized into four groups. Results A total of 939 patients were identified. A total of 549 (58.5%) had EF improved. Both LVESD [odds ratio (OR) per 1 mm decrease, 1.05; 95% CI, 1.04–1.07; P < 0.001] and EF (OR per 1% decrease, 1.06; 95% CI, 1.03–1.10; P < 0.001) at baseline were predictive of EF improvement after revascularization. Patients with LVESD not severely enlarged and EF ≤ 35% had higher odds of being in the EF improved group in comparison with other three groups both in unadjusted and adjusted analysis (all P < 0.001). The median follow-up time was 3.5 years. Patients with LVESD not severely enlarged and EF ≤ 35% had significantly lower risk of all-cause death in comparison with patients with LVESD severely enlarged and EF ≤ 35% [hazard ratio (HR), 2.73; 95% CI, 1.28–5.82; P = 0.009], and tended to have lower risk in comparison with patients with LVESD severely enlarged and EF of 36–40% (HR, 2.00; 95% CI, 0.93–4.27; P = 0.074). Conclusion Among CAD patients with reduced EF (≤ 40%) who underwent revascularization, smaller pre-operative LVESD and lower EF had greatest potential to have EF improvement and better outcome. Our findings imply the indication for revascularization in patients with LV dysfunction who presented with lower EF but smaller LV size.

Abstract
Mitral regurgitation is the most common valvular disease in the US and the second most common worldwide. Left untreated, it can lead to the development of heart failure, giving rise to increased mortality rates. Mitral valve intervention is usually indicated in severe mitral regurgitation at the onset of symptoms, even if the function of the left ventricle is preserved. A surgical approach is generally favored according to current guidelines, with excellent clinical outcomes. However, the emergence of novel data from contemporary trials indicates that percutaneous, catheter-based approach may have similar improvements in mortality outcomes while maintaining a superior safety profile when compared to the surgical approach. Here, we discuss transcatheter mitral valve repair as a treatment option for mitral regurgitation and summarize the major clinical trials which were recently conducted on transcatheter repair.

Prognosis and diastolic dysfunction predictors in patients with heart failure and recovered ejection fraction. Sci Rep 2022; 12:8768. [PMID: 35610337 PMCID: PMC9130289 DOI: 10.1038/s41598-022-12823-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 05/16/2022] [Indexed: 12/28/2022] Open
Abstract
There is limited data on whether diastolic dysfunction in patients with heart failure (HF) and recovered ejection fraction (HFrecEF) is associated with worse prognosis. We retrospectively assessed 96 patients diagnosed with HFrecEF and created ROC curve of their diastolic function at the 1-year follow-up for the composite endpoint of cardiovascular death and HF readmission after the follow-up. Eligible patients were divided into two groups according to the cutoff value of E/e′ ratio (12.1) with the highest AUC (0.70). Kaplan–Meier analysis showed that HFrecEF with high E/e′ group had a significantly poorer prognosis than the low E/e′ group (log-rank, p = 0.01). Multivariate Cox regression analysis revealed that the high E/e′ group was significantly related to the composite endpoint (hazard ratio 5.45, 95% confidence interval [CI] 1.23–24.1). The independent predictors at discharge for high E/e′ ratio at the 1-year follow-up were older age and female sex after adjustment for covariates (odds ratio [OR] 1.07, 95% CI 1.01–1.13 and OR 4.70, 95% CI 1.08–20.5). In conclusion, HFrecEF with high E/e′ ratio might be associated with a poor prognosis. Older age and female sex were independent predictors for a sustained high E/e′ ratio in patients with HFrecEF.

Abstract
Background Certain variables reportedly are associated with a change in left ventricular ejection fraction (LVEF) in heart failure (HF) with reduced ejection fraction (HFrEF). However, literature describing the association between the recovery potential of LVEF and parameters of ventricular remodeling in echocardiography remains sparse. Methods We recruited 2,148 HF patients with LVEF < 35%. All patients underwent at least two echocardiographic images. The study aimed to compare LVEF alterations and their association with patient characteristics and echocardiographic findings. Results Patients with "recovery" of LVEF (follow-up LVEF ≥ 50%) were less likely to have prior myocardial infarction (MI), had a higher prevalence of atrial fibrillation (Af), were less likely to have diabetes and hypertension, and had a smaller left atrium (LA) diameter, left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD), both in crude and in adjusted models (adjustment for age and sex). LVEDD cutoff values of 59.5 mm in men and 52.5 mm in women and LVESD cutoff values of 48.5 mm in men and 46.5 mm in women showed a year-to-year increase in the rate of recovery (follow-up LVEF ≥ 50%)/improvement (follow-up LVEF ≥ 35%), p-value < 0.05 in Kaplan-Meier estimates of the cumulative hazard curves. Conclusions Our study shows that LVEDD and LVESD increments in echocardiography can be predictors of changes in LVEF in in HF patients with LVEF < 35%. They may be used to identify patients who require more aggressive therapeutic interventions.

Manca P, Stolfo D, Merlo M, Gregorio C, Cannatà A, Ramani F, Nuzzi V, Lund LH, Savarese G, Sinagra G. Transient versus persistent improved ejection fraction in non-ischaemic dilated cardiomyopathy. Eur J Heart Fail 2022; 24:1171-1179. [PMID: 35460146 DOI: 10.1002/ejhf.2512] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 03/28/2022] [Accepted: 04/10/2022] [Indexed: 12/22/2022] Open
Abstract
AIMS The recent definition of heart failure with improved ejection fraction outlined the importance of the longitudinal assessment of left ventricular ejection fraction (LVEF). However, long-term progression and outcomes of this subgroup are poorly explored. We sought to assess the LVEF trajectories and their correlations with outcome in non-ischaemic dilated cardiomyopathy (NICM) with improved ejection fraction (impEF). METHODS AND RESULTS Consecutive NICM patients with baseline LVEF ≤40% enrolled in the Trieste Heart Muscle Disease Registry with ≥1 LVEF assessment after baseline were included. ImpEF was defined as a baseline LVEF ≤40%, and second evaluation showing both a ≥10% point increase from baseline LVEF and LVEF >40%. Transient impEF was defined by the documentation of recurrent LVEF ≤40% during follow-up. The primary endpoint was a composite of all-cause death, heart transplantation and left ventricular assist device (D/HT/LVAD). Among 800 patients, 460 (57%) had impEF (median time to improvement 13 months). Transient impEF was observed in 189 patients (41% of the overall impEF group) and was associated with higher risk of D/HT/LVAD compared with persistent impEF at multivariable analysis (hazard ratio 2.54; 95% confidence interval 1.60-4.04). The association of declining LVEF with the risk of D/HT/LVAD was non-linear, with a steep increase up to 8% points reduction, then remaining stable. CONCLUSIONS In NICM, a 57% rate of impEF was observed. However, recurrent decline in LVEF was observed in ≈40% of impEF patients and it was associated with an increased risk of D/HT/LVAD.

The Association of Improvement in Left Ventricular Ejection Fraction with Outcomes in Patients with Heart Failure with Reduced Ejection Fraction: Data from CHAMP-HF. Eur J Heart Fail 2022; 24:762-770. [PMID: 35293088 DOI: 10.1002/ejhf.2486] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 03/08/2022] [Accepted: 03/10/2022] [Indexed: 11/07/2022] Open
Abstract
AIMS We assessed for an association between improvements in left ventricular ejection fraction (LVEF) and future outcomes, including health status, in routine clinical practice. METHODS AND RESULTS CHAMP-HF was a registry of outpatients with heart failure (HF) and LVEF <40%. Enrolled participants completed the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) at regular intervals and were followed as part of routine care. We assessed for associations between improvements in LVEF (>10%) over time and concurrent changes in KCCQ-12, as well as the subsequent risk of poor outcomes. We included 2092 participants in the study. They had the following characteristics: median age 67 years (25th , 75th percentile 58, 75), 29% female, median duration of HF 2.7 years (0.6, 6.8), and median baseline LVEF 30% (23, 35). Of the study participants, 689 (34%) had a >10% absolute improvement in LVEF. Participants with an LVEF improvement also had an improvement in KCCQ-12 overall summary score compared with participants without an LVEF improvement (+7.6 vs +3.5, adjusted effect estimate +4.1 [95% CI 2.3 to 5.7]). Similarly, subsequent all-cause death or HF hospitalization occurred in 12% in the LVEF improvement group vs 25% in the group without an LVEF improvement (adjusted HR 0.50, 95% CI 0.41 to 0.61). CONCLUSION In a large cohort of outpatients with chronic HF, improvements in LVEF were associated with improved health status and a reduced risk for future clinical events. These data underscore the importance of improvement in LVEF as a treatment target for medical interventions for patients with chronic HF.

Cardiol Res 2022; 12:340-343. [PMID: 34970363 PMCID: PMC8683100 DOI: 10.14740/cr1325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Accepted: 10/26/2021] [Indexed: 11/30/2022] Open
Abstract
Background This study aimed to investigate the rate of early improvement in ejection fraction (EF) within 21 - 60 days among patients with cardiomyopathy who were provided with a wearable cardioverter defibrillator (WCD). Methods This was a retrospective study of patients who received a WCD at our institution to determine the rate of improvement in left ventricular EF (LVEF) to ≥ 35-40%. Among 990 patients who received a WCD during the study period, 101 had an echocardiogram performed during the subsequent 21 - 60 days. Patients were stratified according to their initial EF, as well as age, gender, number of heart failure medications, and ischemic vs. nonischemic cardiomyopathy. Multivariate logistic regression analysis was performed to assess the influence of these variables on the subsequent improvement in EF. Results There were 39 patients who had improvement in their EF to ≥ 35-40%. The only significant predictor of EF recovery was the initial EF. There was a direct correlation between initial EF category and the likelihood of improvement in EF. For every unit increase in initial EF category, the odds of improvement increased 1.73 times (95% confidence interval (CI): 1.22 - 2.45). Age (P = 0.20), gender (P = 0.10), ischemic cardiomyopathy (P = 0.40), and number of heart failure medications at the time of WCD placement (P = 0.26) were not significant predictors of improved LVEF. Conclusions This study showed a rate of improvement in EF to ≥ 35-40% of 39% within 21 - 60 days of placement of a WCD among patients with both ischemic and nonischemic cardiomyopathy. The only significant clinical predictor of EF improvement was initial EF.
