Abstract
BACKGROUND The left atrium (LA) plays an important role in the pathophysiology and disease progression of heart failure with preserved ejection fraction (HFpEF). OBJECTIVES This study sought to assess the prognostic potential of LA stiffness index in patients who have HFpEF. METHODS This study retrospectively screened patients with elevated left ventricular end-diastolic pressure (≥16 mm Hg) and preserved ejection fraction (≥50%) between January 1, 2004, and December 31, 2019. All patients underwent left heart catheterization to measure left ventricular end-diastolic pressure. Among these, 307 patients who had suitable image quality for left peak atrial longitudinal strain (PALS) measurement were analyzed. The study population was classified into low LA stiffness (n = 178, early diastolic transmitral inflow velocity/mitral annulus early diastolic velocity [E/e']/PALS ≤0.26) and high LA stiffness (n = 129, E/e'/PALS >0.26) according to the best LA stiffness index (E/e'/PALS) cutoff value. The primary outcome was a composite of mortality or hospitalization caused by heart failure during follow-up. RESULTS LA stiffness index showed good correlations with E/e' (r = 0.737; P < 0.001), LA volume index (r = 0.529; P < 0.001), right ventricular systolic pressure (r = 0.404; P < 0.001), and log N-terminal pro-B-type natriuretic peptide (r = 0.540; P < 0.001). LA stiffness index demonstrated better predictive performance than echocardiographic diastolic parameters did (P < 0.001). Patients with low LA stiffness had better clinical outcomes than those with high LA stiffness during a median follow-up of 6 years did (P < 0.001). In multivariable analysis, LA stiffness index was independently associated with increased risk of the composite endpoint of death or heart failure hospitalization (HR: 1.59 [95% CI: 1.01-2.51]; P = 0.044). CONCLUSIONS Increased LA stiffness was associated with increased risk for all-cause mortality and hospitalization caused by heart failure in patients who have HFpEF, and its prognostic role was more pronounced than that of indexes of left ventricular filling pressure.

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
Background and Aim Type 2 diabetes mellitus (T2DM) is a known risk factor in patients with heart failure (HF), but its impact on phenotypic presentations remains unclear. This study aimed to prospectively examine the relationship between T2DM and functional exercise capacity, assessed by the 6-min walk test (6-MWT) in chronic HF. Methods We studied 344 chronic patients with HF (mean age 61 ± 10 years, 54% female) in whom clinical, biochemical, and anthropometric data were available and all patients underwent an echo-Doppler study and a 6-MWT on the same day. The 6-MWT distance divided the cohort into; Group I: those who managed ≤ 300 m and Group II: those who managed >300 m. Additionally, left ventricular (LV) ejection fraction (EF), estimated using the modified Simpson's method, classified patients into HF with preserved EF (HFpEF) and HF with reduced EF (HFrEF). Results The results showed that 111/344 (32%) patients had T2DM, who had a higher prevalence of arterial hypertension (p = 0.004), higher waist/hips ratio (p = 0.041), higher creatinine (p = 0.008) and urea (p = 0.003), lower hemoglobin (p = 0.001), and they achieved shorter 6-MWT distance (p < 0.001) compared with those with no T2DM. Patients with limited exercise (<300 m) had higher prevalence of T2DM (p < 0.001), arterial hypertension (p = 0.004), and atrial fibrillation (p = 0.001), higher waist/hips ratio (p = 0.041), higher glucose level (p < 0.001), lower hemoglobin (p < 0.001), larger left atrium (LA) (p = 0.002), lower lateral mitral annular plane systolic excursion (MAPSE) (p = 0.032), septal MAPSE (p < 0.001), and tricuspid annular plane systolic excursion (TAPSE) (p < 0.001), compared with those performing >300 m. In the cohort as a whole, multivariate analysis, T2DM (p < 0.001), low hemoglobin (p = 0.008), atrial fibrillation (p = 0.014), and reduced septal MAPSE (p = 0.021) independently predicted the limited 6-MWT distance. In patients with HFpEF, diabetes [6.083 (2.613–14.160), p < 0.001], atrial fibrillation [6.092 (1.769–20.979), p = 0.002], and septal MAPSE [0.063 (0.027–0.184), p = 0.002], independently predicted the reduced 6-MWT, whereas hemoglobin [0.786 (0.624–0.998), p = 0.049] and TAPSE [0.462 (0.214–0.988), p = 0.041] predicted it in patients with HFrEF. Conclusion Predictors of exercise intolerance in patients with chronic HF differ according to LV systolic function, demonstrated as EF. T2DM seems the most powerful predictor of limited exercise capacity in patients with HFpEF.

Abstract
Background Emerging data suggest important prognostic value to left atrial (LA) characteristics, but the independent impact of LA function on outcome remains unsubstantiated. Thus, we aimed to define the incremental prognostic value of LA coupling index (LACI), coupling volumetric and mechanical LA characteristics and calculated as the ratio of left atrial volume index to tissue Doppler imaging a′, in a large cohort of patients with isolated floppy mitral valve. Methods and Results All consecutive 4792 patients (61±16 years, 48% women) with isolated floppy mitral valve in sinus rhythm diagnosed at Mayo Clinic from 2003 to 2011, comprehensively characterized and with prospectively measured left atrial volume index and tissue Doppler imaging a′ in routine practice, were enrolled, and their long‐term survival analyzed. Overall, LACI was 5.8±3.7 and was <5 in 2422 versus ≥5 in 2370 patients. LACI was independently higher with older age, more mitral regurgitation (no 3.8±2.3, mild 5.1±3.0, moderate 6.5±3.8, and severe 7.8±4.3), and with diastolic (higher E/e′) and systolic (higher end‐systolic dimension) left ventricular dysfunction (all P≤0.0001). At diagnosis, higher LACI was associated with more severe presentation (more dyspnea, more severe functional tricuspid regurgitation, and elevated pulmonary artery pressure, all P≤0.0001) independently of age, sex, comorbidity index, ventricular function, and mitral regurgitation severity. During 7.0±3.0 years follow‐up, 1146 patients underwent mitral valve surgery (94% repair, 6% replacement), and 880 died, 780 under medical management. In spline curve analysis, LACI ≥5 was identified as the threshold for excess mortality, with much reduced 10‐year survival under medical management (60±2% versus 85±1% for LACI <5, P<0.0001), even after comprehensive adjustment (adjusted hazard ratio, 1.30 [95% CI, 1.10–1.53] for LACI ≥5; P=0.002). Association of LACI ≥5 with higher mortality persisted, stratifying by mitral regurgitation severity of LA enlargement grade (all P<0.001) and after propensity‐score matching (P=0.02). Multiple statistical methods confirmed the significant incremental predictive power of LACI over left atrial volume index (all P<0.0001). Conclusions LA functional assessment by LACI in routine practice is achievable in a large number of patients with floppy mitral valve using conventional Doppler echocardiographic measurements. Higher LACI is associated with worse clinical presentation, but irrespective of baseline characteristics, LACI is strongly, independently, and incrementally determinant of outcome, demonstrating the crucial importance of LA functional response to mitral valve disease.

Abstract
BACKGROUND The aim of this study was to investigate the relationship between diabetes mellitus (DM) and left atrial (LA) remodelling in a group of patients with heart failure and reduced ejection fraction (HFrEF), and their combined impact on cardiac events (CE). METHODS This study included 136 consecutive HFrEF patients (65 ± 11 years), 36 had DM, and 86 had increased LA stiffness (LASt). All patients underwent complete conventional and tissue Doppler echocardiographic measurements were made including LA volumes and function. LASt was calculated using the formula: LASt = E/e' ratio / PALS. RESULTS At 55 ± 37 months follow-up, free survival from CE was 69% in patients without DM and 44.4% in those with DM (p < .0001). The CE free survival was lower in patients with increased LASt compared to normal LASt, (50 versus. 80%, p < .001), irrespective of the presence of DM (27 versus. 71%, p < .001).The best cut-off value of LASt for predicting CE in the group as a whole was ≥ 0.82% [81% sensitivity, 72% specificity and AUC 0.82 (p < .001)]. LASt ≥ 0.82% also predicted CE in no DM patients [78% sensitivity, 71% specificity and AUC 0.80 (p < .001)] and was a stronger predictor in DM patients [85% sensitivity, 71% specificity and AUC = 0.847 (p < .001)]. CONCLUSION High LA stiffness is associated with poor clinical outcome in patients with HFrEF. Diabetes has an additional incremental value in determining clinical outcome in those patients.

Abstract
OBJECTIVE We examined the left atrial stiffness index (LA Stiff) on echocardiography and its determinants in adults and adolescents with repaired congenital left ventricular outflow obstructions (c-LVOOs), including isolated subaortic stenosis (SAS), stenotic bicuspid aortic valve (BAV), and aortic coarctation (CoA). METHODS Seventy-two patients (43 males, age: 31 ± 15 years) with repaired c-LVOOs (SAS: n = 12; BAV: n = 27; CoA: n = 33) were compared to 72 age- and sex-matched controls. 2D strain imaging was performed to assess left ventricular (LV) and LA function, including peak positive longitudinal LA strain (LAS), late diastolic LA strain (LDS), and LV global longitudinal strain (GLS). The (E/Ea)/LAS ratio was used to calculate LA Stiff. RESULTS LA Stiff was significantly higher in the c-LVOO group than in the control group. Among the c-LVOO patients, the CoA group had the lowest GLS and the highest LA Stiff; no significant differences were found with respect to sex, hypertension history, smoking status, or repeated repair among c-LVOO subtypes. Multivariable regression analysis with the variables "BMI" and "c-LVOO subtype" revealed that BMI and c-LVOO subtypes were independently associated with LA Stiff (b = 0.290, P = .009 and b = 0.353, P = .002, respectively). CONCLUSIONS We documented abnormal LA Stiff values in adults and adolescents after c-LVOO repair. Patients with CoA demonstrated the most impaired LA Stiff values. Overweight may contribute to worse LA Stiff values. Further studies are required to determine the prognostic implications of LA Stiff in patients with repaired c-LVOOs.

Abstract
BACKGROUND AND AIM Left atrial stiffness (LASt) is an important marker of cardiac function, especially in patients with heart failure (HF); it explains symptoms on the basis of pressure transfer to the pulmonary circulation. The aim of this study was to evaluate the relationship between LASt and cardiac events (CE) in HF patients with reduced to mid-range ejection fraction. METHODS The study included 215 consecutive ambulatory HF patients with ejection fraction (EF) < 50% (162 HF reduced EF and 53 HF mid-range EF) of mean age 66 ± 11 years and 24.4% females. Peak LA strain (PALS) was measured by speckle tracking echocardiography and E/e' recorded from the apical four-chamber view. Non-invasive LASt was calculated using the equation: LASt = E/e' ratio/PALS. Documented cardiac events (CE) were HF hospitalization and cardiac death. RESULTS During a median follow up of 41 ± 34 months, 65 patients (30%) had CE. In multivariate analysis model, only raised LV filling pressure (E/e') (OR = 0.292, (95% CI 0.099 to 0.859), p = 0.02), peak pulmonary artery pressure (PAP) (OR = 1.050 (1.009 to 1.094), p = 0.01), PALS (OR = 0.932 (0.873 to 0.994), p = 0.02) and LASt (OR = 3.781 (1.144 to 5.122), p = 0.001) independently predicted CE. LASt ≥ 0.76% was the most powerful predictor of CE, with 80% sensitivity and 73% specificity (AUC 0.82, CI = 0.73 to 0.87, p < 0.001) followed by PALS ≤ 16%, with 74% sensitivity and 72% specificity (AUC 0.77, CI = 0.71 to 0.84, p < 0.001). These results were consistent irrespective of EF (p < 0.05). CONCLUSION In this cohort of ambulatory HFrEF and HFmrEF patients, LASt proved the most powerful predictor of clinical outcome.
