Abstract
Left atrium (LA) is a very important component of cardiovascular performance. The assessment of LA function has gathered the interest with expanding research supporting the utility as a biomarker for outcomes in heart failure (HF). Echocardiography is the main imaging modality which helps in a qualitative and quantitative assessment of the LA size and function. Recent advances in probe technology and software analysis have provided a better understanding of LA anatomy, physiology, pathology, and function. A variety of parameters have been defined as markers of LA function but there is no single parameter that best defines LA function. Speckle tracking echocardiography-derived analysis of LA deformation provides a window on all phases of LA function (reservoir, conduit, and booster pump). There is accumulative published data that supported the diagnostic and prognostic values of LA deformation integration during echo assessment of LA in HF. This review article summarized the clinical utility of LA deformation that may help in prediction, diagnosis, categorization, risk stratification, and guiding the proper selection of therapy in HF patients in daily practice.

Int J Cardiol 2024; 397:131611. [PMID: 38030041 DOI: 10.1016/j.ijcard.2023.131611] [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: 07/20/2023] [Revised: 11/08/2023] [Accepted: 11/23/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND Despite the established benefits of angiotensin receptor-neprilysin inhibitor (ARNI) in heart failure with reduced ejection fraction (HFrEF) across various etiologies, there are controversies regarding the effects of ARNI in patients with irreversible myocardial injury. The aim of this study is to investigate the impact of irreversible myocardial injury on the benefits of ARNI treatment in patients with HFrEF, consisted of both ischemic and non-ischemic etiologies. METHODS AND RESULTS We conducted a retrospective single-center study including 409 consecutive patients with HFrEF treated with ARNI between March 2017 and May 2020. Irreversible myocardial injury was defined as nonviable myocardium without contractile reserve, which suggests a limited potential for recovery of left ventricular function and geometry. At baseline, irreversible myocardial injury was observed in 129 (31.5%) patients. Composite outcome was cardiovascular death or hospitalization for heart failure, which occurred in 56 (43.4%) and 61 (21.8%) patients with and without irreversible myocardial injury, respectively. On multivariable analysis, irreversible injury presence, but not ischemic etiology, was an independent predictor of composite outcome (hazard ratio 2.16, 95% confidence interval 1.33-3.49). Mediation analysis revealed that the increased risk of the composite outcome due to irreversible myocardial injury was mediated by attenuated LV reverse remodeling (Z value = 2.02, P = 0.043). CONCLUSIONS The presence of irreversible myocardial injury was significantly associated with the response to ARNI treatment in patients with HFrEF, regardless of etiology.

Does Speckle Tracking Transthoracic Echocardiography Indicate Subtle Changes in Left Ventricular Function in Heart Failure Patients with Reduced Ejection Fraction Treated by Sacubitril-valsartan? J Cardiovasc Echogr 2024; 34:19-24. [PMID: 38818314 PMCID: PMC11135821 DOI: 10.4103/jcecho.jcecho_5_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 03/20/2024] [Accepted: 04/09/2024] [Indexed: 06/01/2024] Open
Abstract
Background In heart failure patients and reduced ejection fraction (HFrEF), assessing subtle changes in left ventricle (LV) function is crucial for monitoring treatment efficacy. This study aims to determine the effect of valsartan/sacubitril on LV ejection fraction (EF) assessed by two-dimensional (2D) transthoracic echocardiography (TTE) in comparison to that assessed by 2D TTE speckle tracking in patients with HFrEF ≤35% after 6 months of treatment. Patients and Methods A prospective study will be conducted on 200 heart failure patients with reduced EF (HFrEF) undergoing sacubitril-valsartan treatment. Each participant underwent a comprehensive evaluation, including physical examination, history taking, serial 12-lead electrocardiogram, and 2D echo to evaluate cardiac parameters. In addition, 2D speckle tracking echocardiography (STE) assessments were conducted before and after 6 months of valsartan/sacubitril treatment. Results The enrolled patients had an average age of 48 years with 63% females. At the beginning of the study, 9 (4.5%) patients were classified as New York Heart Association (NYHA) FC I, 120 (60%) as NYHA FC II, 64 (32%) as NYHA FC III, and 7 (3.5%) as FC IV. Following treatment, 82 (41%) patients improved to NYHA FC I, and 118 (59%) were in NYHA FC II. Notably, 82 (41%) patients showed improved left ventricular EF (LVEF), detected either by traditional TTE or STE, whereas 118 (59%) showed no improvement in EF through traditional TTE. In addition, 74 (37%) patients demonstrated improvement detected by STE. In contrast, 44 (22%) patients demonstrated no improvement in EF detected by either TTE or STE. Conclusion STE was a more reliable diagnostic method for seeing early LVEF improvement in patients with HFrEF receiving valsartan/sacubitril treatment not seen by conventional TTE.

Abstract
Despite the demonstrated advantages of angiotensin receptor/neprilysin inhibitors in the management of heart failure, the pivotal Angiotensin-Neprilysin Inhibition versus Enalapril in Heart Failure (PARADIGM-HF) trial, which explored this class of medications, did not include individuals from Saudi Arabia. Recognizing that different nations and ethnic groups may exhibit unique characteristics, this study aimed to compare the demographics and outcomes of patients in Saudi Arabia who received sacubitril/valsartan (Sac/Val) with those enrolled in the PARADIGM-HF trial. In this retrospective, multicenter cohort study, we included all adult patients diagnosed with heart failure with reduced ejection fraction (HFrEF) within a tertiary healthcare system in Saudi Arabia between January 2018 and December 2021 and were initiated on Sac/Val. The primary objective was to compare the patient characteristics of those initiating Sac/Val treatment with the participants in the PARADIGM-HF trial. The secondary endpoints included the initiation setting, dose initiation, and titration, as well as alterations in B-type natriuretic peptide and ejection fraction at the 6-month mark. Furthermore, we reported the hospitalization and mortality event rates at the 12-month time point. The study included 400 patients with HFrEF receiving Sac/Val. Compared with the PARADIGM-HF trial, the cohort had a younger mean age and a higher prevalence of diabetes mellitus. SAC/VAL was prescribed as the initial therapy for 34% of the patients, while the remaining participants were initially treated with either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker before transitioning to Sac/Val. Approximately 75% of patients were initiated on 100 mg Sac/Val twice daily, and 90% initiated therapy in the inpatient setting. The mean ejection fraction significantly improved from 26.5 ± 8.4% to 30.5 ± 6.4% at 6 months (P < .001), while the median B-type natriuretic peptide level change was not significant (P = .39). Our study revealed notable disparities in the baseline characteristics of patients with HFrEF compared with those in the PARADIGM-HF trial. These findings offer valuable real-world insights into the prescription patterns and outcomes of Sac/Val in patients with HFrEF in Saudi Arabia, an aspect not previously represented in the PARADIGM-HF study.

Abstract
OBJECTIVE Left ventricular and left atrial strain are sensitive and reliable markers for evaluating cardiac function in patients with type 2 diabetes mellitus (T2DM), with interactions between the two parameters. The present study aimed to analyze the correlation between global longitudinal strain (GLS) of the left ventricle and glycated hemoglobin (HbA1c) levels in patients with T2DM. METHODS A total of 292 patients clinically diagnosed with T2DM were selected and divided into three groups according to HbA1c level. The strains of the left atrium and left ventricle in the three groups of T2DM patients with different HbA1c levels were compared. Univariate and multivariate (including left atrial functional indicators) linear regression analyses were performed to assess the relationship between strain indicators and HbA1c levels. Generalized additive models were used to examine the relationship between strain indicators and HbA1c levels. RESULTS There were significant differences among the three groups in terms of age, microalbuminuria, total cholesterol, fasting blood glucose, postprandial blood glucose, and HbA1c level, and left atrial conduit longitudinal strain (LAScd) and GLS (p < .05). Univariate and multivariate linear regression analyses revealed that, as HbA1c levels increased, the absolute value of GLS gradually decreased (p < .001). Curve fitting revealed a positive correlation between HbA1c level and GLS, which was not affected by left atrial function. CONCLUSION Left ventricular GLS was independently correlated with HbA1c level in patients with T2DM and was not affected by left atrial function.

Abstract
BACKGROUND Management of patients affected by heart failure with reduced ejection fraction (HFrEF) has deeply changed thanks to novel pharmacological therapies, such as Sacubitril/Valsartan, which assured morbidity and mortality advantages in this population. These effects may be mediated by both left atrial (LA) and ventricular reverse remodeling, although left ventricular ejection fraction (LVEF) recovery still represents the main parameter of treatment response. METHODS In this prospective, observational study, 66 patients with HFrEF and naïve from Sacubitril/Valsartan were enrolled. All patients were evaluated at baseline, at 3 months and 12 months from therapy initiation. Echocardiographic parameters, including speckle tracking analysis, LA functional and structural metrics, were collected at three timepoints. The endpoints of our study were: (1) to evaluate the effects of Sacubitril/Valsartan on echo measurements; (2) to assess the predictive role of early modifications of these parameters (expressed as ∆ 3-0 months) on long-term LVEF significant recovery, defined as >15% improvement from baseline. RESULTS The majority of echocardiographic parameters evaluated progressively improved during the observation period, including LVEF, ventricular volumes and LA metrics. ∆(3-0 months) of LV Global Longitudinal Strain (LVGLS) and LA Reservoir Strain (LARS) were associated with significant LVEF improvement at 12 months (p < 0.001 and p = 0.019 respectively). A cut-off of ∆(3-0 months) LVGLS of 3% and of ∆(3-0 months) LARS of 2% could predict LVEF recovery with satisfactory sensitivity and specificity. CONCLUSIONS LV and LA strain analysis may identify patients who adequately respond to HFrEF medical treatment and should be routinely used in the evaluation of these patients.

The Improvement of Left Atrial Function after Twelve Weeks of Supervised Concurrent Training in Patients with Heart Failure with Mid-Range Ejection Fraction: A Pilot Study. J Cardiovasc Dev Dis 2023; 10:276. [PMID: 37504532 PMCID: PMC10381005 DOI: 10.3390/jcdd10070276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 06/21/2023] [Accepted: 06/27/2023] [Indexed: 07/29/2023] Open
Abstract
Left atrial dysfunction is associated with exercise intolerance and poor prognosis in heart failure (HF). The effects of exercise training on atrial function in patients with HF with mid-range ejection fraction (HFmrEF) are unknown. The purpose of the present study was to assess the effects of a supervised concurrent training (SCT) program, lasting 12 weeks, on left atrial function of patients with HFmrEF. The study included 70 stable patients, who were randomly assigned into two groups: SCT with (three sessions/week) or a control (CON) group directed to follow contemporary exercise preventive guidelines at home. Before starting the training program and at 12 weeks, all patients performed an ergometric test, a 6 min walk test, and echocardiography. Between-group comparisons were made by analysis of variance (ANOVA). At 12 weeks, the duration of the ergometric test and distance walked at 6 min walk test presented a significant greater increase in SCT compared to the control (between-group p 0.0001 and p 0.004 respectively). Peak atrial longitudinal strain and conduit strain presented an increase of 29% and 34%, respectively, in the SCT, and were unchanged in CON (between-group p 0.008 and p 0.001, respectively). Peak atrial contraction strain increased by 21% in SCT, with no changes in CON (between-group p 0.002). Left ventricular global longitudinal strain increased significantly in SCT compared to control (between-groups p 0.03). In conclusions, SCT improved left atrial and left ventricular function in HFmrEF. Further studies are needed in order to verify whether these favourable effects of SCT on LA function are sustained and whether they will translate into clinical benefits for patients with HFmrEF.

LCZ696 (sacubitril/valsartan) inhibits pulmonary hypertension induced right ventricular remodeling by targeting pyruvate dehydrogenase kinase 4. Biomed Pharmacother 2023; 162:114569. [PMID: 37001183 DOI: 10.1016/j.biopha.2023.114569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/16/2023] [Accepted: 03/17/2023] [Indexed: 03/31/2023] Open
Abstract
BACKGROUND Right ventricular (RV) function is a major prognostic factor in patients with cardiopulmonary disease. Effective medical therapies are available for left heart failure, but they are usually less effective or even ineffective in right heart failure. Here, we tested the hypothesis that LCZ696 (sacubitril/valsartan) can attenuate pressure overload-induced RV remodeling by inhibiting pyruvate dehydrogenase kinase 4 (PDK4). METHODS Adult male C57 mice were subjected to transverse aortic constriction (TAC), pulmonary artery constriction (PAC), or sham surgery. Bioinformatics analysis was used to screen for common differentially expressed genes (DEGs) between TAC and PAC. Chemical compounds targeting DEGs were predicted by molecular docking analysis. Effects of LCZ696 on PAC-induced RV remodeling and the associated PDK4-related mechanisms were investigated. RESULTS We found 60 common DEGs between PAC and TAC, and Pdk4 was one of the downregulated DEGs. From 47 chemical compounds with potential cardiovascular activity and PDK4 protein binding ability, we selected LCZ696 to treat PAC-induced RV remodeling because of its high docking score for binding PDK4. Compared with vehicle-treated PAC mice, LCZ696-treated mice had significantly smaller RV wall thickness and RV diameters, less myocardial fibrosis, lower expression of PDK4 protein, and less phosphorylation of glycogen synthase kinase-3β (p-GSK3β). In PAC mice, overexpression of Pdk4 blocked the inhibitory effect of LCZ696 on RV remodeling, whereas conditional knockout of Pdk4 attenuated PAC-induced RV remodeling. CONCLUSIONS Pdk4 is a common therapeutic target for pressure overload-induced left ventricular and RV remodeling, and LCZ696 attenuates RV remodeling by downregulating Pdk4 and inhibiting PDK4/p-GSK3β signal.

Sacubitril/Valsartan Improves Left Atrial and Ventricular Strain and Strain Rate in Patients with Heart Failure with Reduced Ejection Fraction. Life (Basel) 2023; 13:995. [PMID: 37109524 PMCID: PMC10142440 DOI: 10.3390/life13040995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 03/21/2023] [Accepted: 04/11/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Data on the impact of sacubitril/valsartan (SV) therapy on phasic left atrial (LA) and left ventricular (LV) strain in heart failure with reduced ejection fraction (HFrEF) are limited. The aim of this study was to evaluate changes in two-dimensional speckle tracking (2D-STE) parameters with SV therapy in HFrEF patients. METHODS Prospective evaluation of HFrEF patients receiving optimized medical therapy. Two-dimensional speckle tracking (2D-STE) parameters were assessed at baseline and after 6 months of SV therapy. LA strain and strain rate (SR) in reservoir, conduit, and contraction phases were compared with LV longitudinal, radial, and circumferential strain and SR and stratified according to heart rhythm and HFrEF etiology. RESULTS A total of 35 patients completed the 6-month follow-up, with a mean age of 59 ± 11 years, 40% in atrial fibrillation, 43% with ischemic etiology, and LVEF of 29 ± 6%. There were significant improvements in LA reservoir, conduit, and contractile strain and SR following SV therapy, particularly among patients in sinus rhythm. There were significant improvements in longitudinal, radial, and circumferential LV function indices. CONCLUSION SV therapy in HFrEF was associated with improved longitudinal, radial, and circumferential function, particularly among patients in sinus rhythm. These findings can provide insights into the mechanisms underlying the improvement of cardiac function and help assess subclinical responses to the treatment.

Abstract
Heart failure (HF) is a common disease that requires appropriate tools to correctly predict cardiovascular outcomes. Echocardiography represents the most commonly used method for assessing left ventricular ejection fraction and a cornerstone in the detection of HF, but it fails to procure an optimal level of inter-observer variability, leading to unsatisfactory prediction of cardiovascular outcomes. In this review, we discuss emerging clinical tools (global longitudinal strain of the left ventricle, the right ventricle, and the left atrium) that permitted an improvement in the diagnosis and ameliorated the risk stratification across different HF phenotypes. The review analyzes the speckle-tracking contributions to the field, discussing the limitations and advantages in clinical practice.

Biventricular longitudinal strain as a predictor of functional improvement after D-shant device implantation in patients with heart failure. Front Cardiovasc Med 2023; 10:1121689. [PMID: 37139125 PMCID: PMC10149702 DOI: 10.3389/fcvm.2023.1121689] [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: 12/12/2022] [Accepted: 03/29/2023] [Indexed: 05/05/2023] Open
Abstract
Background The creation of an atrial shunt is a novel approach for the management of heart failure (HF), and there is a need for advanced methods for detection of cardiac function response to an interatrial shunt device. Ventricular longitudinal strain is a more sensitive marker of cardiac function than conventional echocardiographic parameters, but data on the value of longitudinal strain as a predictor of improvement in cardiac function after implantation of an interatrial shunt device are scarce. We aimed to investigate the exploratory efficacy of the D-Shant device for interatrial shunting in treating heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF), and to explore the predictive value of biventricular longitudinal strain for functional improvement in such patients. Methods A total of 34 patients were enrolled (25 with HFrEF and 9 with HFpEF). All patients underwent conventional echocardiography and two-dimensional speckle tracking echocardiogram (2D-STE) at baseline and 6 months after implantation of a D-Shant device (WeiKe Medical Inc., WuHan, CN). Left ventricular global longitudinal strain (LVGLS) and right ventricular free wall longitudinal strain (RVFWLS) were evaluated by 2D-STE. Results The D-Shant device was successfully implanted in all cases without periprocedural mortality. At 6-month follow-up, an improvement in New York Heart Association (NYHA) functional class was observed in 20 of 28 patients with HF. Compared with baseline, patients with HFrEF showed significant reduced left atrial volume index (LAVI) and increased right atrial (RA) dimensions, as well as improved LVGLS and RVFWLS, at 6-month follow-up. Despite reduction in LAVI and increase in RA dimensions, improvements in biventricular longitudinal strain did not occur in HFpEF patients. Multivariate logistic regression demonstrated that LVGLS [odds ratio (OR): 5.930; 95% CI: 1.463-24.038; P = 0.013] and RVFWLS (OR: 4.852; 95% CI: 1.372-17.159; P = 0.014) were predictive of improvement in NYHA functional class after D-Shant device implantation. Conclusion Improvements in clinical and functional status are observed in patients with HF 6 months after implantation of a D-Shant device. Preoperative biventricular longitudinal strain is predictive of improvement in NYHA functional class and may be helpful to identify patients who will experience better outcomes following implantation of an interatrial shunt device.

Influence of temporal resolution on computed tomography feature-tracking strain measurements. Eur J Radiol 2023; 158:110644. [PMID: 36525702 DOI: 10.1016/j.ejrad.2022.110644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 11/14/2022] [Accepted: 12/05/2022] [Indexed: 12/13/2022]
Abstract
PURPOSE Temporal resolution significantly affects strain values demonstrated by Magnetic resonance feature-tracking and speckle-tracking echocardiography. We investigated the influence of R-R interval reconstruction increments on left ventricular (LV) and left atrial (LA) strain measurements of Computed tomography feature-tracking (CT-FT). METHODS Subjects who underwent retrospective electrocardiogram-gated coronary CT angiography (CCTA) were retrospectively included, and CCTA images were reconstructed in 5% and 10% steps throughout the entire cardiac cycle (0-100% R-R interval). LV global longitudinal strain (GLS), circumferential strain (GCS), radial strain (GRS), LA GLS, ejection fraction (EF), and left atrioventricular coupling indices were computed. We evaluated the consistency and variability of continuous variables between the two reconstruction increment groups, the demarcation between the LA conduit and contraction phases, and observer reproducibility in 20 randomly selected participants. RESULTS Eighty-one participants with or without cardiac disease were included. The reconstruction increment of the R-R interval significantly affected the CT-FT-derived strain values. The 5% R-R increment resulted in significantly larger absolute strain values. LV GRS had the greatest difference between the two groups. In the subgroups with heart rates greater than 80 beats per minute or impaired cardiac function, group differences were attenuated, especially for LV GLS, LV GRS, and LA GLS. The prevalence of definite demarcation between the LA conduit and contraction phases was significantly higher in the 5% R-R reconstruction increment group than in the 10% R-R reconstruction increment group. The average heart rate during CCTA scanning was a strong risk factor for indefinite demarcation, which is independent of LVEF. As average heart rate increased, so did the incidence of indefinite demarcation between the LA conduit and contraction phases. The observer reproducibility of LV and LA strain values was independent of the R-R reconstruction increment. CONCLUSION Reconstruction increment of the R-R interval is an important source of variation in LV and LA CT-FT strain values, especially with low heart rate and preserved cardiac function. It is essential to control the heart rate and apply a narrow R-R reconstruction increment to quantify phasic LA strain.

Assessment of Left Atrial Structure and Function by Echocardiography in Atrial Fibrillation. Diagnostics (Basel) 2022; 12:diagnostics12081898.

Abstract
Atrial fibrillation (AF) is the most common arrhythmia with significant morbidity and mortality. Exacerbated by the aging population, the prevalence of AF is gradually increasing. Accurate evaluation of structure and function of left atrium (LA) has important prognostic significance in patients with AF. Echocardiography is the imaging technique of first choice to assess LA structure and function due to its better availability, accessibility and safety over cardiac computed tomography and cardiac magnetic resonance. Therefore, the aim of this review is to summarize the recent research progress of evaluating LA size by three-dimensional echocardiography and LA function by speckle tracking echocardiography (STE) in predicting the occurrence and recurrence of AF and determining the risk of stroke in AF. In addition, we summarized the role of traditional echocardiography in detecting AF patients that are at high risk of heart failure or cardiovascular death.
