Introduction: Diastolic dysfunction is a potent risk factor for heart failure (HF). However, there is limited data regarding longitudinal changes of diastolic function in the very old, who are at the highest risk for HF. Methods: We studied 2,559 community-based elderly participants in the prospective ARIC study who underwent protocol echocardiography, were in sinus rhythm at study Visits 5 (2011-2013) and 7 (2018-2019), and did not have an interval myocardial infarction. The primary diastolic measures were Tissue Doppler e’, E/e’ ratio, and left atrial volume index (LAVi). Results: Mean age at Visit 5 was 74±4 years, 59% were women, and 25% black. At Visit 5, mean e’ was 5.8±1.4 cm/s, E/e’ 11.8±3.6, and LAVi 24.3±6.7 ml/m 2 . Over a mean of 6.5±3.1 years, e’ decreased by 0.6±1.4 cm/s, E/e’ increased by 3.1±4.5, and LAVi increased by 1.4±7.7 ml/m 2 . Using validated ARIC-based cut-points, there was significant increase in the proportion of participants with abnormal e’ (18% at Visit 5 to 34 % at Visit 7), E/e’ (20% vs 46%), LAVi (17% vs 25%; all p<0.01), and in the number of abnormal diastolic measures ( Figure ). Compared to participants free of cardiovascular (CV) risk factors or CV diseases (n=237), those with CV risk factors or diseases at Visit 5 (n=2,210) demonstrated greater increases in E/e’ (2.3±3.9 vs 3.1±4.5 respectively; p=0.006) and LAVi (0.0±7.0 vs 1.5±7.7 ml/m 2 ; p=0.008) while increases in E/e’ (5.0±5.1; p<0.001) and LAVi (4.6±8.7 ml/m 2 ; p<0.001) were the most prominent in those who developed HF between Visits 5 and 7 (n=60). Conclusions: Diastolic function progressively worsens over 6.5 years in late life, particularly among persons with CV risk factors. Further studies are necessary to determine if risk factor prevention or control will mitigate these changes.

Introduction: Prior research indicates that higher LTPA is associated with better left ventricular (LV) diastolic function, but not with left atrial volume index (LAVI). Left atrial (LA) strain is a more sensitive marker of LA pathology. Hence, we evaluated association of LTPA with LA strain in the ARIC study, a community-based cohort study. Hypothesis: Higher LTPA is associated with better LA reservoir, conduit and contractile function. Methods: We included 4005 participants (mean age 75 years, 63% female, 21% black) with 2D echocardiographic (2DE) LA % strain data, LTPA data, and without prevalent coronary heart disease, valvular heart disease, heart failure, atrial fibrillation, and stroke at Visit 5 (V5, 2011-13). We estimated LTPA as metabolic equivalent-minutes per week from validated Baecke questionnaire and categorized it as poor, intermediate, or ideal as per AHA recommendation. We categorized change in LTPA from V3 (1993-95) to V5 as persistently poor (referent), decreasing, increasing, or persistently active. LA reservoir, conduit, and contractile % strain were measured from speckle-tracking 2DE. Linear regression was used to evaluate association of LTPA with LA function. We modeled LTPA (1) cross-sectionally at V5 as a continuous variable and (2) change from V3 to V5, as continuous and categorical variables (referent- persistently poor). Results: Higher LTPA at V5 (Table) and persistently high (vs poor) LTPA from V3 to 5 (β estimate -0.89, 95% CI -1.40, -0.38) were significantly associated with better LA conduit function after adjusting for CV risk factors, LV function, and LAVI. The same associations with LA reservoir function were no longer significant after adjusting for CV risk factors. LTPA was not associated with LA contractile function (Table). Conclusions: Consistent with LTPA’s salutary effect on LV diastolic function, higher LTPA is associated with better LA conduit function. Maintaining high LTPA from midlife to late-life may be beneficial in mitigating age-related changes in cardiac function.

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 Background Elevated serum uric acid (SUA) is reportedly associated with the traditional left ventricular diastolic dysfunction (LVDD). Purpose We aimed to investigate the association between SUA and the contemporarily defined LV diastolic function (LVDF). Methods We prospectively enrolled healthy individuals who underwent echocardiography to evaluate electrocardiographic abnormalities at the health exam between 1st Jan 2018 and 31th Dec 2019. The evaluation for LVDF includes four criteria: (1) septal E' velocity &lt;7 cm/s or lateral E' &lt;10 cm/s. (2) average E/e' ≥14, (3) left atrial volume index (LAVI) &gt;34 ml/m2, (4) tricuspid regurgitation (TR) velocity &gt;2.8 m/s. The study interest were the presence of the LVDF criteria for each or combined. Results The study consisted of 275 healthy individuals (89% male) with the mean age of 32.9±7.6 years and SUA of 6.1±1.3 mg/dl. The hyperuricemic (N=77) vs. normouricemic (N=198) groups had greater ratio of septal e' &lt;7 (18.2% vs. 5.6%, P=0.002), lateral e' &lt;10 (26% vs. 10.8%, P=0.003), the composite of septal e' &lt;7 or lateral e' &lt;10 (31.6% vs. 13.3%, P=0.001), and average E/e' &gt;14 (3.9% vs. 0%, P=0.021). SUA remained significantly associated with septal e' &lt;7 cm/s (adjusted HR: 1.704, 95% CI: 1.093–2.655, P=0.019) and the presence of any LVDF criteria (adjusted HR: 1.342, 95% CI: 1.044–1.724, P=0.022); Trends toward significant association were found between SUA and average E/e' &gt;14 (adjusted HR: 1.330, 95% CI: 0.981–1.804, P=0.066) and between SUA and lateral e' &lt;10cm/s (adjusted HR: 1.342, 95% CI: 0.970–1.857, P=0.076). Conclusions Elevated SUA was associated with abnormal LVDF in the healthy individuals with normal kidney function. Maintaining SUA level within a normal limit may prevent from the development of abnormal LVDF and LVH. Funding Acknowledgement Type of funding source: Public hospital(s).

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

BACKGROUND: Decreased hydraulic forces during diastole contribute to reduced left ventricular (LV) filling and heart failure with preserved ejection fraction. OBJECTIVES: To determine the association between diastolic hydraulic forces, estimated by atrioventricular area difference (AVAD), and both diastolic function and survival. We hypothesized that decreased diastolic hydraulic forces, estimated as AVAD, would associate with survival independent of conventional diastolic dysfunction measures. METHODS: Patients (n=11,734, median [interquartile range] 3.9 [2.4-5.0] years follow-up, 1,213 events) were selected from the National Echo Database Australia based on the presence of relevant transthoracic echocardiographic measures, LV ejection fraction (LVEF) ≥ 50%, heart rate 50-100 beats/minute, the absence of moderate or severe valvular disease, and no prior cardiac surgery. AVAD was calculated as the cross-sectional area difference between the LV and left atrium. LV diastolic dysfunction was graded according to 2016 guidelines. RESULTS: AVAD was weakly associated with E/e prime, left atrial volume index, and LVEF (multivariable global R2=0.15, p<0.001), and not associated with e prime and peak tricuspid regurgitation velocity. Decreased AVAD was independently associated with poorer survival, and demonstrated improved model discrimination after adjustment for diastolic function grading (C-statistic 0.645 vs 0.607) and E/e prime (C-statistic 0.639 vs 0.621), respectively. CONCLUSIONS: Decreased hydraulic forces, estimated by AVAD, are weakly associated with diastolic dysfunction and provide an incremental prognostic association with survival beyond conventional measures used to grade diastolic dysfunction.

Introduction: Evaluation of left ventricular (LV) filling pressure (FP) plays an important role in the clinical management of pulmonary hypertension (PH). However, the accuracy of echocardiographic parameters for the estimation of LV FP in the presence of pulmonary vascular lesions has not been fully addressed. Methods: We investigated 87 patients diagnosed with PH due to pulmonary vascular lesions (non-cardiac PH; PH NC ) (PH NC group) and 117 patients with ischemic heart disease without reduced LV ejection fraction (<40%) (control group). Mean pulmonary arterial wedge pressure (PAWP) and pulmonary vascular resistance (PVR) were obtained by right heart catheterization. As echocardiographic parameters of LV FP, the ratio of early- (E) to late-diastolic transmitral flow velocity (E/A), ratio of E to early-diastolic mitral annular velocity (E/e'), and left atrial volume index (LAVI) were measured. The PH NC group was subdivided into non-severe and severe groups according to median PVR (5.3 Wood units). Results: PAWP was 12±5 mmHg in controls, 9±4 mmHg in non-severe PH NC , and 8±3 mmHg in severe PH NC . In the control and non-severe PH NC groups, positive correlations were observed between PAWP and E/A (R=0.66 and R=0.41, respectively), E/e' (R=0.36 and R=0.33), and LAVI (R=0.38 and R=0.62). In contrast, in the severe PH NC group, PAWP was only correlated with LAVI (R=0.41, p=0.006). In the control group, PAWP determined E (β=0.45, p<0.001) but PVR did not, whereas both PAWP and PVR were independent determinants of E (β=0.32, p=0.001; and β=-0.35, p<0.001, respectively) in the PH NC group. Conclusions: In the presence of advanced pulmonary vascular lesions, conventional Doppler echocardiographic parameters may not accurately reflect LV FP. Importantly, elevated PVR would lower the E value, even when PAWP is elevated, resulting in blunting of these parameters for the detection of elevated LV FP. LAVI might be a reliable parameter for estimating LV FP in patients with severe non-cardiac PH.

Background: LV geometry predicts CV events but it is unknown whether left atrial volume index (LAVi) predicts mortality independent of LV geometry in patients with preserved LVEF. Methods: We evaluated 47,865 patients with preserved EF to determine the impact of LAVi and LV geometry on mortality during an average follow-up of 1.7±1.0 years. Results: Deceased patients (n=3,653) had significantly higher LAVi (35.3 ± 15.9 vs. 29.1 ± 11.9, p<0.0001) and abnormal LV geometry (60% vs. 41%, p<0.0001) than survivors (n=44,212). LAVi was an independent predictor of mortality in all four LV geometry groups [Hazard ratio: N= 1.007 (1.002–1.011), p=0.002; concentric remodeling= 1.008 (1.001–1.012), p<0.0001; eccentric hypertrophy= 1.012 (1.006 –1.018), p<0.0001; concentric hypertrophy=1.017 (1.012–1.022), p<0.0001; Figure ]. Comparison of models with and without LAVi for mortality prediction was significant suggesting increased mortality prediction by addition of LAVi to other independent predictors (Table ). Conclusion: LAVi is higher and LV geometric abnormalities are more prevalent in deceased patients with preserved systolic function and are independently associated with increased mortality. LAVi predicts mortality independent of LV geometry and has synergistic influence on all cause mortality prediction in large cohort of patients with preserved ejection fraction.
