Abstract Background and Aim Diabetes mellitus (DM) affects left ventricular remodeling in patients with heart failure (HF), but its effect on left atrial (LA) remodeling and their combined effect on survival and other clinical events (CE) remain to be elucidated. We evaluated in this study the relationship between DM and left atrial (LA) remodeling in a group of HF patients with reduced ejection fraction (HFrEF), Methods This studied 136 consecutive HFrEF patients (65 ± 11 years), 36 diabetics, using conventional and tissue Doppler echocardiography. LA dimension and function were measured and cavity stiffness was calculated with the formula: LA stiffness = E/e’ratio/LA strain. Results The age, gender, LV end-systolic dimension, LV end-diastolic dimension, LV EF and BNP level did not differ between diabetic and non-diabetic patients. Diabetic patients with HFrEF had higher NYHA functional class (p = 0.02), reduced right ventricle (RV) systolic function (p = 0.01) and increased LA stiffness (p = 0.02) . At follow up of 55 ± 37 months, survival free from CE was 69% in non-diabetics compared with 44.4% in diabetics (X2 12.7; p< 0.0001). The CE free survival was lower in patients with increased LA stiffnes, irrespective of the presence of DM: 1) Patients with HFrEF without DM and normal LA stiffness (85%); 2) Patients with HFrEF without DM and with increased LA stiffness (50%); 3) Patients with HFrEF with DM and with normal LA stiffness (71%) and patients with HFrEF with DM and with increased LA stiffness (27%) (X2 29.6; p< 0.0001, Figure 1). Conclusion Compromised LA stiffness as surrogate of LA remodeling is associated with poor outcome in patients with heart failure and reduced EF. The presence of diabetes in patients with HFrEF and increased LA stiffness has incremental prognostic value. Abstract P791 Figure.

Reduced Ejection Fraction

Sacubitril/valsartan reduces mortality in heart failure with reduced ejection fraction (HFrEF) patients, partially due to cardiac reverse remodeling (RR). Little is known about the RR rate in long-lasting HFrEF and the evolution of advanced echocardiographic parameters, despite their known prognostic impact in this setting. We sought to evaluate the rates of left ventricle (LV) and left atrial (LA) RR through standard and advanced echocardiographic imaging in a cohort of HFrEF patients, after the introduction of sacubitril/valsartan. A multi-parametric standard and advanced echocardiographic evaluation was performed at the moment of introduction of sacubitril/valsartan and at 3 to 18 months subsequent follow-up. LVRR was defined as an increase in the LV ejection fraction ≥10 points associated with a decrease ≥10% in indexed LV end-diastolic diameter; LARR was defined as a decrease >15% in the left atrium end-systolic volume. We analyzed 77 patients (65 ± 11 years old, 78% males, 40% ischemic etiology) with 76 (28–165) months since HFrEF diagnosis. After a median follow-up of 9 (interquartile range 6–14) months from the beginning of sacubitril/valsartan, LVRR occurred in 20 patients (26%) and LARR in 33 patients (43%). Moreover, left ventricular global longitudinal strain (LVGLS) improved from −8.3 ± 4% to −12 ± 4.7% (p < 0.001), total left atrial emptying fraction (TLAEF) from 28.2 ± 14.4% to 32.6 ± 13.7% (p = 0.01) and peak atrial longitudinal strain (PALS) from 10.3 ± 6.9% to 13.7 ± 7.6% (p < 0.001). In HFrEF patients, despite a long history of the disease, the introduction of sacubitril/valsartan provides a rapid global (i.e., LV and LA) RR in >25% of cases, both at standard and advanced echocardiographic evaluations.

Background: Heart failure is a common clinical syndrome and is the final stage of most cardiovascular diseases. Nowadays, the role of left atrium in cardiovascular diseases, especially in HF diseases, is more and more important. At the early stage of heart failure, the size and pump function of left atrium are increased. When the left ventricular function is reduced significantly, left atrial function is alo impaired. Aims of the study: assess size and function of left atrium in patient with heart failure reduced ejection fraction (HFrEF). Establishing the association between two indexs above with some clinical and subclinical characteristics. Subjects and method: 51 HFrEF patients in Hospital of Hue University of Medicine and Pharmacy, who have including criteria. Cross-sectional study. Results: LAVI (ml/m2): 43.19 ± 12.48 ml/m2, percentage of large left atrial patents is 80.4%. LATEF (%): 31.93 ± 7.72%. LAVI has correlation with: LVEDV (r= 0,45); LVESV (r= 0,43); NT-proBNP (r= 0.371). There is a difference LAVI of diastolic dysfunction grades (r= 0.011), There is a difference LAVI of NYHA class (r= 0.016). LATEF has correlation with NTproBNP (r= -0.349). Conclusion: The left atrium’s size is increased and its function is reduced in HFrEF patient. There is a positive correlation between LAVI and LVEDV, LVESV, NTproBNP. The LAVI varies with the diastolic dysfunction grade. And there is a negative correlation between LATEF and NTproBNP. Key words: heart failure reduced ejection fraction; size of left atrium, function of left atrium

Background/Aims: Chronic kidney disease (CKD) is common among patients with heart failure with preserved ejection fraction (HFpEF) and is associated with worse clinical outcomes. This study aims to identify whether the association of CKD with HFpEF is independent of underlying echocardiographic abnormalities. Materials: We conducted a retrospective cohort study including patients without prevalent heart failure referred for echocardiography. Patients with serial echocardiograms, baseline left ventricular ejection fraction (LVEF) ≥50% and estimated glomerular filtration rate (eGFR) ≥90 mL/min/1.73 m2 were matched 1:1 with patients with eGFR <60 mL/min/1.73 m2 for age (±5 years), sex, history of hypertension or diabetes, use of renin-angiotensin inhibitors, and LVEF (±5%). A secondary analysis included patients with preserved LVEF and normal left ventricular mass index matched for the same parameters except use of renin-angiotensin inhibitors. Results: Patients with CKD were at increased risk for HFpEF admission: crude hazard ratio (HR) 1.79 (95% confidence interval [CI] 1.38–2.32, p < 0.001) and adjusted HR (for coronary disease, loop diuretics, left atrial diameter) 1.64 (95% CI 1.22–2.21, p = 0.001). LVEF and left ventricular diameter decreased over time in both groups but no difference was observed in rate of dropping. Results were similar in the secondary analysis (crude HR 1.99, 95% CI 1.07–3.71, p = 0.03 and HR adjusted for left atrial diameter 1.98, 95% CI 1.05–3.75, p = 0.04). Rate of change was similar for LVEF, pulmonary artery pressure, and left ventricular mass index in both groups. Conclusion: CKD is independently associated with incident HFpEF despite a similar change in relevant echocardiographic parameters in patients with or without CKD.

Objective Evidence

Heart failure with preserved left ventricular ejection fraction (HF-PEF), sometimes named diastolic heart failure, is a common condition most frequently seen in the elderly and is associated with arterial hypertension and left ventricular (LV) hypertrophy. Symptoms are attributed to a stiff left ventricle with compensatory elevation of filling pressure and reduced ability to increase stroke volume by the Frank-Starling mechanism. LV interaction with stiff arteries aggravates these problems. Prognosis is almost as severe as for heart failure with reduced ejection fraction (HF-REF), in part reflecting co-morbidities. Before the diagnosis of HF-PEF is made, non-cardiac etiologies must be excluded. Due to the non-specific nature of heart failure symptoms, it is essential to search for objective evidence of diastolic dysfunction which, in the absence of invasive data, is done by echocardiography and demonstration of signs of elevated LV filling pressure, impaired LV relaxation, or increased LV diastolic stiffness. Antihypertensive treatment can effectively prevent HF-PEF. Treatment of HF-PEF is symptomatic, with similar drugs as in HF-REF.

Echocardiographic Parameters

Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test &lt;0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p&lt;0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p&lt;0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p&lt;0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.
