Background. Left ventricular (LV) ejection fraction (EF) and LV volumes were reported to have prognostic efficacy in cardiac diseases. In particular, the end-systolic volume index (LVESVI) has been featured as the most reliable prognostic indicator. However, such efficacy in patients with LVEF ≥ 50% has not been elucidated. Methods. We screened the patients who received cardiac catheterization to evaluate coronary artery disease concomitantly with both left ventriculography and LV pressure recording using a catheter-tipped micromanometer and finally enrolled 355 patients with LVEF ≥ 50% and no history of heart failure (HF) after exclusion of the patients with severe coronary artery stenosis requiring early revascularization. Cardiovascular death or hospitalization for HF was defined as adverse events. The prognostic value of LVESVI was investigated using a Cox proportional hazards model. Results. A univariable analysis demonstrated that age, log BNP level, tau, peak − dP/dt, LVEF, LV end-diastolic volume index (LVEDVI), and LVESVI were associated with adverse events. A correlation analysis revealed that LVESVI was significantly associated with log BNP level (r = 0.356, p<0.001), +dP/dt (r = −0.324, p<0.001), −dP/dt (r = 0.391, p<0.001), and tau (r = 0.337, p<0.001). Multivariable analysis with a stepwise procedure using the variables with statistical significance in the univariable analysis revealed that aging, an increase in BNP level, and enlargement of LVESVI were significant prognostic indicators (age: HR: 1.071, 95% CI: 1.009–1.137, p=0.024; log BNP : HR : 1.533, 95% CI: 1.090–2.156, p=0.014; LVESVI : HR : 1.051, 95% CI: 1.011–1.093, p=0.013, respectively). According to the receiver-operating characteristic curve analysis for adverse events, log BNP level of 3.23 pg/ml (BNP level: 25.3 pg/ml) and an LVESVI of 24.1 ml/m2 were optimal cutoff values (BNP : AUC : 0.753, p<0.001, LVESVI : AUC : 0.729, p<0.001, respectively). Conclusion. In patients with LVEF ≥ 50%, an increased LVESVI is related to the adverse events. LV contractile performance even in the range of preserved LVEF should be considered as a role of a prognostic indicator.

Background: Attempts to characterize cardiac structure in heart failure with preserved ejection fraction (HFpEF) in people with type 2 diabetes (T2D) have yielded inconsistent findings. We aimed to determine whether patients with HFpEF and T2D have a distinct pattern of cardiac remodelling compared with those without diabetes and whether remodelling was related to circulating markers of inflammation and fibrosis and clinical outcomes. Methods: We recruited 140 patients with HFpEF (75 with T2D and 65 without). Participants underwent comprehensive cardiovascular phenotyping, including echocardiography, cardiac magnetic resonance imaging and plasma biomarker profiling. Results: Patients with T2D were younger (age 70 ± 9 versus 75 ± 9y, p = 0.002), with evidence of more left ventricular (LV) concentric remodelling (LV mass/volume ratio 0.72 ± 0.15 versus 0.62 ± 0.16, p = 0.024) and smaller indexed left atrial (LA) volumes (maximal LA volume index 48 ± 20 versus 59 ± 29 ml/m2, p = 0.004) than those without diabetes. Plasma biomarkers of inflammation and extracellular matrix remodelling were elevated in those with T2D. Overall, there were 45 hospitalizations for HF and 22 deaths over a median follow-up period of 47 months [interquartile range (IQR) 38–54]. There was no difference in the primary composite endpoint of hospitalization for HF and mortality between groups. On multivariable Cox regression analysis, age, prior HF hospitalization, history of pulmonary disease and LV mass/volume were independent predictors of the primary endpoint. Conclusions: Patients with HFpEF and T2D have increased concentric LV remodelling, smaller LA volumes and evidence of increased systemic inflammation compared with those without diabetes. This suggests the underlying pathophysiology for the development of HFpEF is different in patients with and without T2D. ClinicalTrials.gov identifier: NCT03050593.

Abstract Background Dilated cardiomyopathy (DCM) is increasingly recognized as a heterogenous disease with distinct phenotypes on late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging. While mid-wall striae (MWS) fibrosis is a widely recognized phenotypic risk marker, other fibrosis patterns are prevalent but poorly defined. Right ventricular (RV) insertion (RVI) site fibrosis is commonly seen, but without objective criteria has been considered a non-specific finding. In this study we developed objective criteria for RVI fibrosis and studied its clinical relevance in a large cohort of patients with DCM. Methods We prospectively enrolled 645 DCM patients referred for LGE-CMR. All underwent standardized imaging protocols and baseline health evaluations. LGE images were blindly scored using objective criteria, inclusive of RVI site and MWS fibrosis. Associations between LGE patterns and CMR-based markers of adverse chamber remodeling were evaluated. Independent associations of LGE fibrosis patterns with the primary composite clinical outcome of heart failure admission or death were determined by multivariable analysis. Results The mean age was 56 ± 14 (28% female) with a mean left ventricular (LV) ejection fraction (LVEF) of 37%. At a median of 1061 days, 129 patients (20%) experienced the primary outcome. Any abnormal LGE was present in 306 patients (47%), inclusive of 274 (42%) meeting criteria for RVI site fibrosis and 167 (26%) for MWS fibrosis. All with MWS fibrosis showed RVI site fibrosis. Solitary RVI site fibrosis was associated with higher bi-ventricular volumes [LV end-systolic volume index (78 ± 39 vs. 66 ± 33 ml/m2, p = 0.01), RV end-diastolic volume index (94 ± 28 vs. 84 ± 22 ml/m2 (p < 0.01), RV end-systolic volume index (56 ± 26 vs. 45 ± 17 ml/m2, p < 0.01)], lower bi-ventricular function [LVEF 35 ± 12 vs. 39 ± 10% (p < 0.01), RV ejection fraction (RVEF) 43 ± 12 vs. 48 ± 10% (p < 0.01)], and higher extracellular volume (ECV). Patient with solitary RVI site fibrosis experienced a non-significant 1.4-fold risk of the primary outcome, increasing to a significant 2.6-fold risk when accompanied by MWS fibrosis. Conclusions RVI site fibrosis in the absence of MWS fibrosis is associated with bi-ventricular remodelling and intermediate risk of heart failure admission or death. Our study findings suggest RVI site fibrosis to be pre-requisite for the incremental development of MWS fibrosis, a more advanced phenotype associated with greater LV remodeling and risk of clinical events.

The purpose of this study was to compare the echocardiographic features of Irish wolfhounds with clinically inapparent dilated cardiomyopathy (DCM) (n = 33) to dogs with advanced DCM (n = 33) and to normal dogs (n = 262). Significant differences were detected between the three groups. In dogs with DCM, the most sensitive diagnostic measurements were: end-systolic volume index (ESVI), E-point to septal separation (EPSS), fractional shortening (FS), and left ventricular internal dimensions (LVIDd and LVIDs). Left atrial diameter was increased markedly in dogs with DCM and 83.3% of affected Irish wolfhounds had concurrent atrial fibrillation. Compared with early DCM, in advanced DCM there was a significant increase in end-diastolic right ventricular diameter, often combined with extensive pleural effusion, the leading sign of congestive heart failure in Irish wolfhounds.

Echocardiographic Evaluation

This systematic review is based on 19 studies from Elsevier, PubMed, Embase, and Scopus databases, which were found by the following keywords: LA strain (left atrial strain), STE (speckle tracking echocardiography), HF (heart failure), and HFpEF (heart failure with preserved ejection fraction). The review focuses on results and conclusions of studies on using the 2D echocardiographic evaluation of left atrial (LA) myocardial strain for early diagnosis of HFpEF in routine clinical practice. Analysis of the studies included into this review showed a significant decline of all LA functions in patients with HFpEF. Also, multiple studies have reported associations between decreased indexes of LA strain and old age, atrial fibrillation, left ventricular hypertrophy, left and right ventricular systolic dysfunction, and LV diastolic dysfunction. Thus, the review indicates significant possibilities of using indexes of LA strain in evaluation of early stages of both systolic and diastolic myocardial dysfunction. Notably, LA functional systolic and diastolic indexes are not sufficiently studied despite their growing significance for diagnosis and prognosis of patients with HFpEF. For this reason, in addition to existing models for risk stratification in this disease, including clinical characteristics and/or echocardiographic data, future studies should focus on these parameters.

Abstract Ischemic heart disease is a major causes of heart failure. Heart failure patients have predominantly left ventricular dysfunction (systolic or diastolic dysfunction, or both). Acute heart failure is most commonly caused by reduced myocardial contractility, and increased LV stiffness. We performed echocardiography and gated SPECT with Tc99m MIBI within 263 patients and 166 normal individuals. Left ventricular end systolic volume (LVESV), left ventricular end diastolic volume (LVEDV), and left ventricular ejection fraction (LVEF) were measured. For all degrees of ischemia, there was a significant difference between ejection fraction values measured by SPECT and echocardiography, and there were no significant differences among end systolic volume and end diastolic volume value calculated by two methods for all cases. The mean value for EDV (ECHO)/EDV (SPECT) was 1.07 ± 0.31 for degree (1, 2); in the degree 3 the mean value was 1.02 ± 0.08, and 1.005 ± 0.07 for degree 4. The mean value for ESV (ECHO)/ESV (SPECT) was 1.08 ± 0.34 for degree (1, 2); while 1.03 ± 0.12, 1.021 ± 0.128 for degree 3 and 4 respectively. This study was showed a good relation between left ventricular size and ejection fraction measured by SPECT with Tc99m, and echocardiography.

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.

Exercise improves morbidity, fatality rate, and quality of life in heart failure with low ejection fraction, but fewer data available in heart failure with preserved ejection fraction (HFPEF).The purpose of this study is to test the hypothesis that exercise training might improve the longitudinal intrinsic left ventricular (LV) function in HFPEF patients.This quasi-experimental study had recruited 30 patients with HFPEF. Exercise training program had been performed for a month with a total of 20 times exercise sessions and evaluated every 2 weeks. Echocardiography was performed before sessions, second week and fourth week of exercise training. Six-minute walk tests (6MWTs) and quality-of-life variables using Minnesota living with HF scoring and the 5-item World Health Organization Well-Being Index scoring were measured before and after exercise as well.Left ventricular filling pressure, represented by the ratio of early diastolic mitral flow velocity/early diastolic annular velocity and left atrial volume index, improved during exercise. The longitudinal intrinsic LV function, represented by four-chamber longitudinal strain, augmented during exercise (p < 0.001). Aerobic capacity, measured by 6MWT, increased significantly (p = 0.001). Quality of life improved significantly during exercise (p < 0.001).Exercise training was suggested to improve the longitudinal intrinsic LV function and quality of life in HFPEF.

The Impact

Echocardiography of right ventricular (RV)-arterial coupling obtained by the estimation of the ratio of the longitudinal annular systolic excursion of the tricuspid annular plane and pulmonary artery systolic pressure (TAPSE/PASP) has been found to be a remarkable prognostic indicator in patients with HF. Our aim was to evaluate the impact of TAPSE, PASP and their ratio in the prognostic stratification of outpatients with HF aged ≥70 years and reduced to mid-range ejection fraction (EF). A complete echocardiographic examination was performed in 400 outpatients with chronic HF and left ventricular (LV) EF ≤50% who averaged 77 years in age. During a median follow-up period of 25 months (interquartile range: 8-46), there were 135 cardiovascular deaths. Two different Cox regression models were evaluated, one including TAPSE and PASP, separately, and the other with TAPSE/PASP. In the first model, LV end-systolic volume index, age, no angiotensin converting enzyme (ACE) inhibitor use, TAPSE, PASP and gender were found to be independently associated with the outcome after adjustment for demographics, clinical, biochemical, echocardiographic data. In the second model, TAPSE/PASP resulted the most important independent predictor of outcome (hazard ratio [HR]:0.07, p<0.0001) followed by LV end-systolic volume index, no ACE inhibitor use, age and gender. The use of the variable TASPE/PASP improved the predictive value of the new multivariable model (area under the curve [AUC] of 0.74 vs AUC of 0.71; p<0.05). TASPE/PASP improved the net reclassification (NRI = 14.7%; p<0.01) and the integrated discrimination (IDI = 0.04; p<0.01). In conclusion, the study findings showed that assessment of RV-arterial coupling by TAPSE/PASP was of major importance to assess the prognosis of patients with chronic HF and LV EF ≤50% aged ≥70 years.
