Abstract
BACKGROUND Left atrial strain (LAS) analysis represents a newer non-invasive, sensitive and specific technique for assessing left atrial (LA) function and early detection of its deformation and dysfunction. However, its applicability in mitral regurgitation (MR) in pediatric population remains unexplored, raising pertinent questions regarding its potential role in evaluating the severity and progression of the disease. OBJECTIVE To investigate the impact of chronic MR in children and adolescents on LA remodeling and function. METHODS The study included 100 participants. Patients with primary and secondary chronic MR lasting at least 5 years fit our inclusion criteria. The exclusion criteria from the study were: patients with functional mitral regurgitation due to primary cardiomyopathies, patients with artificial mitral valve, patients with MR who had previously undergone surgery due to obstructive lesions of the left heart (aortic stenosis, coarctation of the aorta), patients with significant atrial rhythm disorders (atrial fibrillation, atrial flutter). The echocardiographic recordings were conducted by two different cardiologists. Outcome data was reported as mean and standard deviation (SD) or median and interquartile range (Q1-Q3). RESULTS The study included 100 participants, of whom 50 had MR and the remaining 50 were without MR. The average age of all participants was 15.8 ± 1.2 years, with a gender distribution of 37 males and 63 females. There was a significant difference in the values of LA volume index (LAVI), which were higher in patients with MR (p= 0.0001), S/D ratio (and parameters S and D; p= 0.001, p= 0.0001, p= 0.013), mitral annulus radius (p= 0.0001), E/A ratio (p= 0.0001), as well as septal e' (m/s), lateral e' (m/s), and average E/e' ratio, along with the values of TV peak gradient and LV global longitudinal strain (%). There was no significant difference in LA strain parameters, nor in LA stiffness index (LASI). CONCLUSION Our findings revealed significant differences in several echocardiographic parameters in pediatric patients with MR relative to those without MR, providing insight into the multifaceted cardiac structural and functional effects of MR in this vulnerable population.

High-Intensity Interval Training Versus Moderate Continuous Training in Patients With Heart Failure With Preserved Ejection Fraction: A Systematic Review and Meta-analysis. Curr Probl Cardiol 2023; 48:101720. [PMID: 36967072 DOI: 10.1016/j.cpcardiol.2023.101720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 03/21/2023] [Indexed: 04/28/2023]
Abstract
High-intensity interval training (HIIT) is a novel training approach that improves cardiopulmonary fitness and functional capacity in numerous chronic conditions, however its impact in patients with heart failure (HF) with preserved ejection fraction (HFpEF) is uncertain. We evaluated data from prior studies reporting the effects of HIIT versus moderate continuous training (MCT), on cardiopulmonary exercise outcomes in patients with HFpEF. PubMed and SCOPUS were queried from inception till February 1st, 2022 for all randomized controlled trials (RCT) comparing the effect of HIIT versus MCT in patients with HFpEF on peak oxygen consumption (peak VO2), left atrial volume index (LAVI), respiratory exchange ratio (RER), and ventilatory efficiency (VE/CO2 slope). A random-effects model was applied, and the weighted mean difference (WMD) of each outcome was reported with 95% confidence intervals (CI). Three RCTs (total N = 150 patients with HFpEF), with a follow-up of 4 to 52 weeks were included in our analysis. Our pooled analysis demonstrated that HIIT significantly improved peak VO2 (WMD = 1.46 mL/kg/min (0.88, 2.05); P < 0.00001; I2 = 0%), as compared to MCT. However, no statistically significant change was demonstrated for LAVI (WMD = -1.71 mL/m2 (-5.58, 2.17); P = 0.39; I2 = 22%), RER (WMD = -0.10 (-0.32, 0.12); P = 0.38; I2 = 0%), and VE/CO2 slope (WMD = 0.62 (-1.99, 3.24); P = 0.64; I2 = 67%) in patients with HFpEF. Across current RCT data, HIIT, compared to MCT, had a significant impact on improving peak VO2. Conversely, there was no significant change in LAVI, RER, and VE/CO2 slope between HFpEF patients undertaking HIIT as opposed to MCT.

Abstract
In recent years, new interest is growing in the left atrium (LA). LA functional analysis and measurement have an essential role in cardiac function evaluation. Left atrial size and function are key elements during the noninvasive analysis of diastolic function in several heart diseases. The LA represents a “neuroendocrine organ” with high sensitivity to the nervous, endocrine, and immune systems. New insights highlight the importance of left atrial structural, contractile, and/or electrophysiological changes, introducing the concept of “atrial cardiomyopathy”, which is closely linked to underlying heart disease, arrhythmias, and conditions such as aging. The diagnostic algorithm for atrial cardiomyopathy should follow a stepwise approach, combining risk factors, clinical characteristics, and imaging. Constant advances in imaging techniques offer superb opportunities for a comprehensive evaluation of LA function, underlying specific mechanisms, and patterns of progression. In this literature review, we aim to suggest a practical, stepwise algorithm with integrative multimodality imaging and a clinical approach for LA geometry and functional analysis. This integrates diastolic flow analysis with LA remodelling by the application of traditional and new diagnostic imaging techniques in several clinical settings such as heart failure (HF), atrial fibrillation (AF), coronary artery disease (CAD), and mitral regurgitation (MR).

Abstract
AIM To investigate the association between the left atrial volume index (LAVI) and the incidence of cardiovascular events in patients with acute coronary syndrome (ACS) who did not have atrial fibrillation (AF). METHODS In this sub-analysis of the HIJ-PROPER study, 226 ACS patients who did not have a history of AF were enrolled. Participants were divided into two groups according to the LAVI cut-off level calculated by receiver operating characteristic (ROC) curve analysis to predict the primary endpoint, and cardiovascular events were compared between groups. The primary endpoint was the first occurrence of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and hospitalization for heart failure. RESULTS ROC curve analysis for the occurrence of composite of cardiovascular events indicated a LAVI cut-off point of 34 mL/m2 . Based on this, 131 patients (58.0%) were in the LAVI < 34 mL/m2 group and 95 (42.0%) were in the LAVI ≥ 34 mL/m2 group. Over a median follow-up period of 4.0 years [interquartile range: 3.2, 5.1], cardiovascular events were noted in 7 and 15 patients in the LAVI < 34 mL/m2 and LAVI ≥ 34 mL/m2 groups, corresponding to an incidence rate of 5.3% and 15.8%, respectively. Patients with a LAVI value ≥ 34 mL/m2 had a significantly higher risk of cardiovascular events than those with a LAVI value < 34 mL/m2 (hazard ratio: 2.93; 95% confidence interval: 1.19-7.22; P = .014). The tendency was similar after adjusting for several confounders (P = .025). CONCLUSION In ACS patients without AF, elevated LAVI was associated with increased cardiovascular events.

Abstract
BACKGROUND In the absence of mitral valve disease, increased left atrial volume (LAV) is a marker of diastolic dysfunction and long-standing elevated left ventricle (LV) pressure. The aim of this study was to assess the role of increased baseline LAV in predicting clinical outcome of patients presenting with acute coronary syndrome (ACS). METHODS We systematically searched all electronic databases up to September 2020 in order to select clinical trials and observational studies, which assessed the predictive role of LAV indexed (LAVI) on clinical outcome in patients with ACS. Primary clinical endpoints were as follows: major adverse cardiac events (MACE), all-cause mortality and hospitalization. Secondary endpoints were in-hospital complications. RESULTS A total of 2,705 patients from 11 cohort studies with a mean follow-up 18.7 ± 9.8 months were included in the meta-analysis. Patients with low LAVI had low risk for MACE (15.9% vs. 33.7%; p < .01), long-term all-cause mortality (9.14% vs. 18.1%; p < .01), short-term mortality (3.31% vs. 9.38%; p = .02) and lower hospitalization rate (11.6% vs. 25.5%; p < .01) compared to patients with increased LAVI. Atrial fibrillation and cardiogenic shock as in-hospital events were lower (p < .05 for all) in patients with low LAVI but ventricular fibrillation/tachycardia was not different between groups (p = .14). CONCLUSION Increased LAVI is an independent predictor of outcome in patients with ACS. Thus, assessment of LA index in these patients is important for better risk stratification and guidance towards optimum clinical management.

Abstract
Backgrounds Assessment of left ventricular filling pressure (LVFP) is of clinical importance in patients with ST elevation myocardial infarction (STEMI). Although several echocardiographic parameters are recommended for the assessment of LVFP, validation of these parameters in patients with STEMI is missing. We aimed to investigate the clinical utility of these parameters in acute settings. Methods: We prospectively included consecutive patients with STEMI. LV end-diastolic pressure (LVEDP) was measured following primary PCI and echocardiographic examination was performed within 24 hours. Mean left atrial pressure (mLAP) was calculated both invasively using Yamamoto's formula and non-invasively using Naugeh's formula. Mean LAP was considered increased when exceeded 18 mmHg. Results: Patients were grouped according to LVEDP, group 1(41 patients) and group 2(114 patients).There was no significant difference between groups in terms of comorbidities. NT pro-BNP levels (p < 0.001) and peak level of Hs-TnT (p-value: 0.002) were significantly higher in group 2. Average E/e' ratio was significantly higher in group 2 (10.19 ± 3.15 vs. 12.04 ± 4.83, p: 0.046). Isovolumetric relaxation time was longer in group 2 (p < 0.001) and left atrial volume index (LAVI) was also significantly higher in group 2 (p < 0.001). Regression analyses revealed that septal, lateral and average E/e' ratio, tricuspid regurgitation velocity, LAVI and left ventricular volume are correlated with mLAP. Among group 2 patients only 14 Patients fulfilled the increased LVFP criteria suggested by current guidelines. Conclusions Echocardiographic parameters indicating increased LVFP require validation and may need to be modified in patients with STEMI. Moreover, current algorithms underestimate the actual number of patients with increased LVFP.

Abstract
Diastolic dysfunction (DD) is a common condition that is increasingly encountered in patients undergoing both cardiac and noncardiac surgery as the age profile of our patient population increases and the noninvasive diagnosis of DD becomes more accessible. There is a growing body of evidence demonstrating the significance of DD and adverse perioperative outcomes, and thus, it is becoming imperative for anesthesiologists to have an understanding of the pathophysiology, diagnosis, and management of patients with DD. Current guidelines are based on transthoracic echocardiogram (TTE) measurements in patients who are spontaneously breathing and in a euvolemic state and, consequently, not applicable to the perioperative period. In this review article, we discuss the grading of DD as well as introduce a practical approach to the diagnosis and management of patients with DD during the perioperative period.

Left atrial volume index: Can it provide additional prognostic information in ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention? Rev Port Cardiol 2018; 37:799-807.

Abstract
INTRODUCTION We sought to assess the prognostic impact of left atrial (LA) size on long-term outcomes of ST-segment elevation myocardial infarction (STEMI). METHODS We studied 200 consecutive patients admitted to a single center between January 2010 and December 2014 with non-fatal STEMI treated with primary percutaneous coronary intervention (pPCI) who underwent a comprehensive echocardiographic examination at discharge. LA volume was estimated by the area-length method. The left atrium was classified as normal, mildly, moderately or severely enlarged by LA volume index (LAVI). The endpoints were defined as all-cause mortality, a cardiac composite endpoint (all-cause mortality, reinfarction, unplanned revascularization and hospitalization for heart failure) and a cardiovascular composite endpoint (cardiac endpoint plus atrial fibrillation and ischemic stroke) during follow-up. RESULTS In this STEMI population, 58% had normal LA size, 22.5% had mild LA enlargement, 10% had moderate LA enlargement and 9.5% had severe LA enlargement. During a median follow-up of 28 (IQR 21-38) months, 14 (7.0%) patients died, 53 (26.5%) had the cardiac and 58 (29%) the cardiovascular composite endpoints. There was a stepwise increase in the incidence of all-cause mortality (p=0.020) and both cardiac (p<0.001) and cardiovascular (p<0.001) endpoints with each increment of LAVI class. In multivariate analysis, severe LA enlargement by LAVI was an independent predictor of all-cause mortality (HR: 11.153; 95% CI: 1.924-64.642, p=0.007) and the cardiac (HR: 4.351; 95% CI: 1.919-9.862, p<0.001) and cardiovascular (HR: 4.351; 95% CI: 1.919-9.862, p<0.001) endpoints during follow-up. CONCLUSIONS This contemporary study confirms the prognostic effect of LA size at discharge, applying the most recent reference values in STEMI patients treated with pPCI.

Abstract
Left atrial enlargement (LAE) is a risk factor for cardiovascular complications and death. In hypertensive patients, LAE is usually due to left ventricular (LV) hypertrophy and diastolic dysfunction. We aimed to identify factors associated with LAE in patients with increased and normal left ventricular mass index (LVMI) with reference to pulsatile and steady components of blood pressure (BP).The study was carried out as a cross-sectional observation. In a group of inhabitants of suburban area of Cracow, Poland, we measured office, ambulatory and central BP, carotid-femoral pulse wave velocity (PWV), as well as echocardiographic indices and gathered anthropometric data, information on habits and relevant medical history. Further, with division according to sex-stratified dichotomised LVMI, we performed correlation analysis to identify possibly significant relations between measures of left atrial volume and other studied parameters. We also fitted regression models in order to assess the respective value of steady and pulsatile BP components as factors related to measures of left atrial volume.The mean age of 205 patients (136 females-66%) was 53.6 ± 8.3 years. We found higher values of PWV, office, ambulatory and central BPs in the group of LVMI above median value. This group had also greater left atrial volume index (LAVI), which correlated with LVMI (r = 0.36, P < .001) and ratio of early diastolic mitral peak flow velocity to early diastolic mitral annulus mean velocity in tissue Doppler imaging (E/e') (r = 0.24, P = .04).In the group of LVMI below the median, LAVI correlated with pulsatile and steady BP components. LAVI was independently predicted by mean arterial pressure (MAP) obtained from both ambulatory (MAP24h, β= 0.15; P = .045) and office measurements (MAPoffice, β = 0.35; P = .004), but not by pulse pressure.LV mass and function are the main determinants of LAVI. However, in persons with lower LV mass, LAVI depends on the steady component of blood pressure, but not pulsatile one. Increased LAVI reflects early changes in response to systemic blood pressure elevation.

Abstract
Background The left atrial size has been considered as a useful marker of adverse cardiovascular outcomes. However, it is not well known whether left atrial area index (LAAI) has predictive value for prognosis in patients with unstable angina pectoris (UAP). This study was aimed to assess the association between LAAI and outcomes in UAP patients. Methods We enrolled a total of 391 in-hospital patients diagnosed as UAP. Clinical and echocardiographic data at baseline were collected. The patients were followed for the development of adverse cardiovascular (CV) events, including hospital readmission for angina pectoris, acute myocardial infarction (AMI), congestive heart failure (CHF), stroke and all-cause mortality. Results During a mean follow-up time of 26.3 ± 8.6 months, 98 adverse CV events occurred (84 hospital readmission for angina pectoris, four AMI, four CHF, one stroke and five all-cause mortality). In a multivariate Cox model, LAAI [OR: 1.140, 95% CI: 1.016–1.279, P = 0.026], diastolic blood pressure (OR: 0.976, 95% CI: 0.956–0.996, P = 0.020) and pulse pressure (OR: 1.020, 95% CI: 1.007–1.034, P = 0.004) were independent predictors for adverse CV events in UAP patients. Conclusions LAAI is a predictor of adverse CV events independent of clinical and other echocardiographic parameters in UAP patients.

Left atrial volume index and prediction of events in acute coronary syndrome: Solar Registry. Arq Bras Cardiol 2014; 103:282-91. [PMID: 25119895 PMCID: PMC4206358 DOI: 10.5935/abc.20140122] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2014] [Accepted: 04/30/2014] [Indexed: 12/21/2022] Open
Abstract
Background According to some international studies, patients with acute coronary syndrome
(ACS) and increased left atrial volume index (LAVI) have worse long-term
prognosis. However, national Brazilian studies confirming this prediction are
still lacking. Objective To evaluate LAVI as a predictor of major cardiovascular events (MCE) in patients
with ACS during a 365-day follow-up. Methods Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated
within 48 hours after hospital admission. According to LAVI, two groups were
categorized: normal LAVI (≤ 32 mL/m2) and increased LAVI (> 32
mL/m2). Both groups were compared regarding clinical and
echocardiographic characteristics, in- and out-of-hospital outcomes, and
occurrence of ECM in up to 365 days. Results Increased LAVI was observed in 78 patients (45%), and was associated with older
age, higher body mass index, hypertension, history of myocardial infarction and
previous angioplasty, and lower creatinine clearance and ejection fraction. During
hospitalization, acute pulmonary edema was more frequent in patients with
increased LAVI (14.1% vs. 4.3%, p = 0.024). After discharge, the occurrence of
combined outcome for MCE was higher (p = 0.001) in the group with increased LAVI
(26%) as compared to the normal LAVI group (7%) [RR (95% CI) = 3.46
(1.54-7.73) vs. 0.80 (0.69-0.92)]. After Cox regression, increased LAVI
increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012). Conclusion Increased LAVI is an important predictor of MCE in a one-year follow-up.
