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.

Introduction: Changes in N-terminal pro brain natriuretic peptide (NT-proBNP) have been demonstrated to correlate with outcomes in patients with heart failure (HF) and reduced ejection fraction (EF). However the prognostic value of a change in NT-proBNP in patients with heart failure and preserved ejection fraction (HFPEF) is unknown. Hypothesis: To assess the impact of changes in NT-proBNP on all-cause mortality, HF hospitalization and their composite in an unselected population of patients with HFPEF. Methods: 643 outpatients (age 72+12 years; 41% females) with HFPEF (ejection fraction ≥40%) enrolled in the Swedish Heart Failure Registry between 2005 and 2012 and reporting NT-proBNP levels assessment at initial registration and at follow-up were prospectively studied. Patients were divided into 2 groups according the median value of NT-proBNP absolute change that was 0 pg/ml. Median follow-up from first measurement was 2.25 years (IQR: 1.43 to 3.81). Adjusted Cox’s regression models were performed using total mortality, HF hospitalization (with censoring at death) and their composite as outcomes. Results: After adjustments for 19 baseline variables including baseline NT-proBNP, as compared with an increase in NT-proBNP levels at 6 months (NT-proBNP change>0 pg/ml), a reduction in NT-proBNP levels (NT-proBNP change<0 pg/ml) was associated with a 45.2% reduction in risk of all-cause death (HR: 0.548; 95% CI: 0.378 to 0.796; p:0.002), a 50.1% reduction in risk of HF hospitalization (HR: 0.49; 95% CI: 0.362 to 0.689; p<0.001) and a 42.6% reduction in risk of the composite outcome (HR: 0.574; 95% CI: 0.435 to 0.758; p<0.001)(Figure). Conclusions: Reductions in NT-proBNP levels over time are independently associated with an improved prognosis in HFPEF patients. Changes in NT-proBNP could represent a surrogate outcome in phase 2 HFPEF trials.

Left Atrial Stiffness

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.

Abstract Background and Aim Left atrial (LA) stiffness is an important marker of cardiac pump function, especially in patients with heart failure (HF) and preserved ejection fraction (HFpEF). The aim of this study was to evaluate the relationship between LA stiffness and cardiac events (CE) in HF patients with reduced ejection fraction (HFrEF). Methods This study included 136 consecutive HFrEF outpatients (mean age: 65 ± 11 years). A complete conventional and tissue Doppler imaging study was performed. The LA dimension and function were measured. Non invasive LA stiffness was calculated with the following formula: LA stiffness = E/e’ratio/LA strain. The cardiac events were HF hospitalization and cardiac death. Results During a median follow up of 55 ± 37 months, 51 patients had CE, they had higher NYHA functional class (p = 0.001), higher LV end-diastolic dimension (p = 0.001), higher LV end-systolic dimension (p = 0.04), lower EF (p &lt; 0.001), higher E/A ratio (p = 0.01) and reduced TAPSE (p = 0.001) compared with patients without CE. LA volume index was higher (p = 0.001), LA strain was reduced and LA stiffness was increased in patients with CE compared to those without CE (p = 0.0001, p &lt; 0.0001, respectively). LA stiffness exhibited the closest relationship with E/e’ ratio (r = 0.67, p &lt; 0.001). Survival analyses showed that LA stiffness [HR: 4.026 (1.300–12.468), p = 0.001] was the most powerful independent predictor of cardiac events[C1] . On ROC curve analysis, a LA stiffness &lt; 0.82% was 81% sensitive and 73% specific (AUC 0.81, p &lt; 0.001) in predicting clinical events (Figure 1). Conclusion In this cohort of outpatients with HFrEF, LA stiffness proved the most important predictor of clinical outcome. [C1] Abstract P1544 Figure.

The Impact

Background: Sacubitril/valsartan has been shown to be superior to enalapril in reducing the risks of death and hospitalization for heart failure (HF). However, knowledge of the impact on cardiac performance remains limited. We sought to evaluate the effects of sacubitril/valsartan on clinical, biochemical and echocardiographic parameters in patients with heart failure and reduced ejection fraction (HFrEF). Methods: Sacubitril/valsartan was administered to 205 HFrEF patients. Results: Among 230 patients (mean age 59 ± 10 years, 46% with ischemic heart disease) 205 (89%) completed the study. After a follow-up of 10.49 (2.93 ± 18.44) months, the percentage of patients in New York Heart Association (NYHA) class III changed from 40% to 17% (p < 0.001). Median N–Type natriuretic peptide (Nt-proBNP) decreased from 1865 ± 2318 to 1514 ± 2205 pg/mL, (p = 0.01). Furosemide dose reduced from 131.3 ± 154.5 to 120 ± 142.5 (p = 0.047). Ejection fraction (from 27± 5.9% to 30 ± 7.7% (p < 0.001) and E/A ratio (from 1.67 ± 1.21 to 1.42 ± 1.12 (p = 0.002)) improved. Moderate to severe mitral regurgitation (from 30.1% to 17.4%; p = 0.002) and tricuspid velocity decreased from 2.8 ± 0.55 m/s to 2.64 ± 0.59 m/s (p < 0.014). Conclusions: Sacubitril/valsartan induce “hemodynamic recovery” and, consistently with reduction in Nt-proBNP concentrations, improve NYHA class despite diuretic dose reduction.
