AbstractPulmonary hypertension (PHT) is associated with increased mortality in hemodialysis (HD) patients. The ventricular gradient optimized for right ventricular pressure overload (VG-RVPO) is sensitive to early changes in right ventricular overload. The study aimed to assess the ability of the VG-RVPO to detect PHT and predict all-cause and cardiac mortality in HD patients. 265 selected HD patients were enrolled. Clinical, biochemical, electrocardiographic, and echocardiographic parameters were evaluated. Patients were divided into normal and abnormal VG-RVPO groups, and were followed-up for 3 years. Abnormal VG-RVPO patients were more likely to be at high or intermediate risk for PHT, were older, had longer HD vintage, higher prevalence of myocardial infarction, higher parathormone levels, shorter pulmonary flow acceleration time, lower left ventricular ejection fraction, higher values of left atrial volume index, left ventricular mass index, and peak tricuspid regurgitant velocity. Both all-cause and CV mortality were higher in abnormal VG-RVPO group. In multivariate Cox analysis, VG-RVPO remained an independent and strong predictor of all-cause and CV mortality. In HD patients, abnormal VG-RVPO not only predicts PHT, but also all-cause and CV mortality.

AbstractHeart failure with preserved ejection fraction (HFpEF) is highly prevalent in patients on maintenance haemodialysis (HD) and lacks effective treatment. We investigated the effect of spironolactone on cardiac structure and function with a specific focus on diastolic function parameters. The MiREnDa trial examined the effect of 50 mg spironolactone once daily versus placebo on left ventricular mass index (LVMi) among 97 HD patients during 40 weeks of treatment. In this echocardiographic substudy, diastolic function was assessed using predefined structural and functional parameters including E/e’. Changes in the frequency of HFpEF were analysed using the comprehensive ‘HFA-PEFF score’. Complete echocardiographic assessment was available in 65 individuals (59.5 ± 13.0 years, 21.5% female) with preserved left ventricular ejection fraction (LVEF > 50%). At baseline, mean E/e’ was 15.2 ± 7.8 and 37 (56.9%) patients fulfilled the criteria of HFpEF according to the HFA-PEFF score. There was no significant difference in mean change of E/e’ between the spironolactone group and the placebo group (+ 0.93 ± 5.39 vs. + 1.52 ± 5.94, p = 0.68) or in mean change of left atrial volume index (LAVi) (1.9 ± 12.3 ml/m2 vs. 1.7 ± 14.1 ml/m2, p = 0.89). Furthermore, spironolactone had no significant effect on mean change in LVMi (+ 0.8 ± 14.2 g/m2 vs. + 2.7 ± 15.9 g/m2; p = 0.72) or NT-proBNP (p = 0.96). Treatment with spironolactone did not alter HFA-PEFF score class compared with placebo (p = 0.63). Treatment with 50 mg of spironolactone for 40 weeks had no significant effect on diastolic function parameters in HD patients.The trial has been registered at clinicaltrials.gov (NCT01691053; first posted Sep. 24, 2012).

Abstract BackgroundPericardial fat (PF) has been suggested to directly act on cardiomyocytes, leading to diastolic dysfunction. The aim of this study was to investigate whether PF volume is associated with diastolic function independently.Methods254 healthy adults (50-70 years, BMI 18-35 kg/m2, normal left ventricular ejection fraction) from the cardiology outpatient department were included in this study. All patients underwent a coronary computed tomographic angiography for the measurement of pericardial fat volume, as well as a transthoracic echocardiography for the assessment of diastolic function parameters. To assess the independent association of PF and diastolic function parameters multivariable linear regression analysis was performed. To maximize differences in PF volume, the group was divided in low (lowest quartile of both sexes) and high (highest quartile of both sexes) PF. Multivariable binary logistic analysis was used to study the associations within the groups between PF and diastolic function, adjusted for age, BMI and sex.ResultsSignificant associations for all four diastolic parameters with the PF volume were found after adjusting for BMI, age, and sex. In addition, subjects with high pericardial fat had a reduced left atrial volume index (p=0.02), lower E/e (p<0.01) and E/A (p=0.01), reduced e’ lateral (p<0.01), reduced e’ septal p=0.03), compared to subjects with low pericardial fat.ConclusionThese findings confirm that pericardial fat, even in healthy subjects with normal cardiac function, is associated with diastolic function. Our results suggest that the mechanical effects of PF may limit the distensibility of the heart and thereby directly contribute to diastolic dysfunction. Trial registration NCT01671930

Abstract Background Significant tricuspid regurgitation (TR) can be found in patients with atrial fibrillation (AF). The results of previous studies are controversial about whether significant functional TR (FTR) in patients with AF leads to worse clinical outcomes. The aims of the study were to investigate the prevalence, predictors and prognosis of significant FTR in patients with AF with preserved left ventricular ejection fraction (LVEF). Methods The present study was a retrospective cohort study in patients with AF and preserved LVEF from May 2013 through January 2018. Significant FTR was defined as moderate to severe TR without structural abnormality of the tricuspid valve. Pulmonary hypertension (PH) was defined as pulmonary artery systolic pressure ≥ 50 mmHg or mean pulmonary artery pressure ≥ 25 mmHg determined by echocardiography. The adverse outcomes were defined as heart failure and death from any cause within 2 years of follow up. Results A total of 300 patients with AF (mean age 68.8 ± 10.8 years, 50% male) were included in the study. Paroxysmal and non-paroxysmal AF were reported in 34.7 and 65.3% of patients, respectively. Mean LVEF was 65.3 ± 6.3%. PH and significant FTR were observed in 31.3 and 21.7% of patients, respectively. Patients with significant FTR were significantly older, more female gender and non-paroxysmal AF, and had higher left atrial volume index and pulmonary artery pressure than those without. A total of 26 (8.7%) patients died and heart failure occurred in 39 (13.0%) patients. There was a statistically significant difference in the adverse outcomes between patients with significant and insignificant FTR (44.6% vs. 11.9%, p <  0.010). Multivariable analysis showed that factors associated with significant FTR were female gender, presence of PH and left atrial volume index (OR = 2.61, 1.87, and 1.04, respectively). The predictors of the adverse outcomes in patients with AF were significant FTR, presence of PH and high CHA2DS2-VASc score (OR = 5.23, 2.23 and 1.60, respectively). Conclusions Significant FTR was common in patients with AF, and independently associated with adverse outcomes. Thus, comprehensive echocardiographic assessment of FTR in patients with AF and preserved LVEF is fundamental in determining the optimal management.

Abstract Background In Japan, ivabradine is indicated in patients with heart failure (HF) with sinus rhythm and a resting heart rate (HR) ≥75/min under standard treatment. Particularly, it is effective for HF with reduced left ventricular ejection fraction (LVEF). However, elderly people have a higher incidence of atrial fibrillation than young people, and their sinus node function is further deteriorated, resulting in a lower intrinsic HR. In addition, Japan is an ultra-aging society, especially in the countryside; therefore, the target patients for ivabradine may be limited in these regions. Purpose We sought to estimate the possible candidates for ivabradine and investigate their clinical characteristics in our hospital located in rural Japan. Method and results We retrospectively studied 14733 consecutive patients who were suspected heart disease who underwent echocardiography between January 2006 and October 2018 in Kitaishikai Hospital located in Ozu city (Proportion of the population aged ≥65 years: 34%, in 2015) and did not take ivabradine treatment. Of these, 187 patients with hemodynamically stable condition whose E/A ratio was measured and met the criteria of LVEF &lt;40% and HR ≥75 /min were confirmed. Of these, 153 patients reached HR &lt;75 /min with additional intensive medication within one year after the index echocardiography (Controlled group; mean HR: 82 to 62/min). The remaining 34 patients with uncontrolled HR (Uncontrolled group; mean HR: 84 to 82/min) were considered possible candidates for ivabradine (34/14733: 0.23%, 2.6 patients per year; median age, 74 years; male, 56%; median LVEF, 32%; ischemic cardiomyopathy, 53%). In the comparison of clinical and echocardiographic parameters in these two groups, Uncontrolled group had a significantly smaller left ventricular diastolic volume index (71 [59–85] vs 82 [66–109] /ml/m2, p=0.02), left ventricular systolic volume index (50 [39–59] vs 59 [42–80] / ml/m2, p=0.04), stroke volume index (22 [18–26] vs 26 [20–32] /ml/m2, p=0.02), left atrial volume index (47 [40–64] vs 59 [45–71] /ml/m2, p=0.02), and more hemodialysis (12 vs 3%, p=0.04) than Controlled group. However, the discrimination ability of these parameters for identifying Uncontrolled group was modest (Figure). Conclusion In rural Japan, possible candidates for ivabradine may be rare, so daily attention should be paid. Patients with reduced ejection fraction, small left ventricle, and hemodialysis may be the possible targets for this therapy. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background and aim The occurrence of right ventricular failure (RVF) in patients with chronic left heart disease (LHD) has important therapeutic and prognostic consequences. Echocardiography (Echo) parameters describing the RV longitudinal function (tricuspid annular plane systolic excursion, TAPSE; peak systolic free wall longitudinal strain, RV-Str; tricuspid annulus peak systolic velocity, TAPSm) are today commonly used to define RV dysfunction. In the present study we hypothesised that these parameters are load dependent. Methods We retrospectively included 66 patients with LHD (age 52 ± 13 years, males 79%) that underwent right heart catheterization (RHC) and Echo within 48 hours. RHC was performed as part of diagnostic- or pre-transplant work-up. Fifty-six patients (85%) had left ventricular ejection fraction &lt; 40%. From RHC data the patients were divided into three groups: Patients with RV decompensation and increased right atrial pressure (RAP) ≥10 mmHg (iRAP, n = 21), with normal RAP but reduced stroke volume index (SVI &lt; 35 mL/m2) (rSVI, n = 21) and with normal RAP and normal SVI (nSVI, n = 24). Results Patients with iRAP had compared with rSVI/nSVI more advanced LHD with higher PAMP, PCWP and larger RV diastolic area (RVdA). TAPSE, RV-Str and FAC did not differ between iRAP and rSVI patients. The ratio RVdA/RV-Str was significantly higher in iRAP patients compared with rSVI and nSVI. The rSVI and nSVI patients did not differ regarding RAP response during supine exercise (P = 0.84). Conclusions Reduced RV longitudinal function in patients with chronic LHD and normal RAP can be due to left ventricular forward failure and not RV systolic dysfunction. iRAP (n = 21) rSVI (n = 21) nSVI (n = 24) Overall P-value iRAP vs rSVI iRAP vs nSVI rSVI vs nSVI RAP (mmHg) 13 ± 2 5 ± 3 4 ± 2 &lt;0.001 &lt;0.001 &lt;0.001 0.34 PAMP (mmHg) 33 ± 8 24 ± 8 22±] &lt;0.001 0.001 &lt;0.001 0.34 PCWP (mmHg) 22 ± 5 16 ± 8 11 ± 6 &lt;0.001 0.003 &lt;0.001 0.025 CI (l/min/m2) 2.2 ± 0.4 2.2 ± 0.4 2.8 ± 0.5 &lt;0.001 0.75 &lt;0.001 &lt;0.001 PVR (Wood unit) 2.6 ± 1.2 1.5 ± 1.6 1.9 ± 1.0 0.032 0.022 0.035 0.60 RVdA (cm2) 26 ± 7 21 ± 7 21 ± 5 0.012 0.007 0.017 0.63 TAPSE (mm) 12 ± 3 13 ± 3 18 ± 6 &lt;0.001 0.28 &lt;0.001 0.001 TAPSm (cm/s) 8 ± 2 8 ± 2 10 ± 4 0.06 - - - RV-str (%) -15 ± 5 -17 ± 5 -21 ± 6 0.002 0.11 0.001 0.028 FAC (%) 28 ± 9 29 ± 11 39 ± 11 &lt;0.001 0.72 0.001 0.003 RVdA/RV-str (cm2/%) 2.2 ± 1.3 1.3 ± 0.7 1.1 ± 0.6 &lt;0.001 0.013 0.001 0.27
