Background: Heart failure is increasing in the elderly and represents a socioeconomic burden requiring the correct management for which risk stratification is mandatory. Among younger patients, echocardiogram and cardiopulmonary exercise test are useful in prognostic stratification. Few studies have analyzed the utility of these tests in elderly patients. Methods: We report on 90 patients over 70 years old, on whom cardiopulmonary tests and echocardiograms were performed between 1998 and 2006 (67 M, 23 F; 75 ± 3 years; ejection fraction (EF) 30 ± 6%; NYHA 2.1 ± 0.8; 60% ischemic; therapy according to international guidelines). Echocardiographic variables were (1) left ventricular ejection fraction (EF); (2) severity of diastolic dysfunction on multiparametric examination of Doppler and TDI parameters; (3) severity of functional mitral regurgitation. Cardiopulmonary variables were (1) peak VO2; (2) peak O2 pulse; (3) peak respiratory quotient (RQ); (4) VE/VCO2 slope. Endpoint considered was mortality of any cause at three-years follow-up. Results: Mortality was 21%. At univariate analysis, survivors ( n = 71) and deceased ( n = 19) were similar for age, NYHA class, peakVO2 and RQ; they differed for EF, severity of mitral regurgitation, severity of diastolic dysfunction, O2 pulse and VE/VCO2 slope. At multivariate analysis, only VE/VCO2 slope and severe diastolic dysfunction (restrictive filling pattern) discriminated between the two groups. In particular, the association of restrictive filling pattern and VE/VCO2 slope ≥ 45 predicted 3-year mortality with sensitivity of 84% and specificity of 88%. Conclusions: Echocardiographic and cardiopulmonary data can identify high-risk elderly patients with systolic heart failure, who may need aggressive clinical management.

Patients With Heart Failure

Background: Hospitalized patients with acute decompensated heart failure (ADHF) frequently exhibit aggravating mitral regurgitation (MR). Those patients do not always undergo surgical mitral valve repair, but particularly in the elderly, they are often treated by conservative medical therapy. This study was aimed to investigate factors affecting 6-month outcomes in hospitalized patients with heart failure (HF) harboring surgically untreated MR.Methods: We screened the presence of MR in hospitalized patients with HF between September 2017 and May 2020 in the Yamaguchi Prefectural Grand Medical (YPGM) center. At the time of discharge of these patients, individuals with surgically unoperated MR, including primary and secondary origin, were consequently recruited to this single-center prospective cohort study. The patients with severe MR who undergo surgical mitral valve treatment were not included in this study. The primary endpoint was all-cause readmission or all-cause death and the secondary endpoint was HF-related endpoint at 6 months after discharge. The Cox proportional hazard regression analyses were employed to assess the predictors for the composite endpoint.Results: Overall, 489 patients with ADHF were admitted to the YPGM center. Of those, 146 patients (30% of total patients with HF) (median age 83.5 years, 69 men) were identified as harboring grade II MR or greater. Consequently, all the recruited patients were diagnosed as functional MR. During a median follow-up of 186.0 days, a total of 55 patients (38%) reached the primary or secondary endpoints (HF death and readmission in 31 patients, other in 24 patients). As a result of multivariate analysis, geriatric nutritional risk index [hazard ratio (HR) = 0.932; 95% CI = 0.887–0.979, p = 0.005], age (HR = 1.058; 95% CI = 1.006–1.112, p = 0.027), and left ventricular ejection fraction (HR = 0.971; 95% CI = 0.945–0.997, p = 0.030) were independent predictors of all-cause death or all-cause admission. Body mass index (HR = 0.793; 95% CI = 0.614–0.890, p = 0.001) and ischemic heart disease etiology (HR = 2.732; 95% CI = 1.056–7.067, p = 0.038) were also independent predictors of the HF-related endpoints.Conclusion: Malnutrition and underweight were substantial predictors of adverse outcomes in elderly patients with HF harboring surgically untreated moderate-to-severe functional MR.

OBJECTIVETo investigate the relation between plasma adrenomedullin and the severity of diastolic dysfunction in patients with heart failure.DESIGNProspective study.SETTINGUniversity teaching hospital.PATIENTS77 patients (mean (SEM) age 66.3 (1.2) years; 75% male) who were being followed in the outpatient clinic after admission to hospital for acute heart failure.INTERVENTIONSSame day echocardiography with Doppler studies; determination of venous adrenomedullin concentration by radioimmunoassay.MAIN OUTCOME MEASURESPlasma adrenomedullin concentration and its correlation with systolic and diastolic function.RESULTS31 patients (40%) had isolated diastolic dysfunction (ejection fraction > 50%), and the remaining 46 had a depressed ejection fraction (< 50%). Of the patients with diastolic dysfunction, 17 had a restrictive filling pattern. In all but one of these there was coexisting systolic failure (χ2 = 10.7, p = 0.001). Patients with systolic heart failure and a restrictive filling pattern (group 1, n = 16) had a higher plasma adrenomedullin than those with systolic failure and a non-restrictive filling pattern (group 2, n = 30) or with isolated diastolic heart failure and a non-restrictive filling pattern (group 3, n = 30) (mean (SEM): 91.7 (21.1) v 38.4 (8.8) v 34.0 (6.5) pmol/l, both p < 0.05). All heart failure values were higher (p < 0.01) than the control value (6.9 (1.2) pmol/l). Ejection fraction and left ventricular dimensions were similar in groups 1 and 2. Plasma adrenomedullin did not correlate with ejection fraction or New York Heart Association functional class. Stepwise multiple regression analysis showed that the presence of a restrictive filling pattern was the only independent variable associated with a high plasma adrenomedullin.CONCLUSIONSPlasma adrenomedullin concentrations in patients with heart failure are determined by the presence of diastolic dysfunction, and are especially raised in the presence of a restrictive filling pattern. There appears to be no correlation with systolic dysfunction.

Abstract Background The optimal treatment for patients with nonparoxysmal atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF) has been a subject of debate for years. We aimed to evaluate the efficacy and safety of catheter ablation (CA) of nonparoxysmal AF in patients with HFrEF and functional mitral regurgitation (MR). Methods This single-center, retrospective, and observational study enrolled 21 consecutive patients with nonparoxysmal AF, HFrEF and functional MR underwent CA༎The ablation strategy consisted of bilateral circumferential pulmonary vein isolation and empirical linear ablations. Results After a mean follow-up of 18.2 ± 8.5 months, stable sinus rhythm (SR) was achieved in 15 patients (71.4%) after the initial procedure and 17 patients (81%) after the final procedure. The NYHA class improved from 2.7 ± 0.7 before ablation to 1.2 ± 0.4 during follow-up (p < 0.001). Left ventricular ejection fraction increased from 36.5 ± 6.3% to 54.9 ± 6.6% (p < 0.001). Among 17 patients in continuous SR after the final procedure, MR severity decreased to mild or none,and 10 patients with decreased ventricular wall motion was completely restored to normal after the procedure. No serious complications occurred. Conclusion CA may be a safe and effective method for treating nonparoxysmal AF in patients with HFrEF and functional MR. It can significantly improve HF symptoms, functional MR and left ventricular function..

Background: The prognostic importance of right ventricular (RV) dysfunction has been suggested in patients with systolic heart failure (due to primary or secondary dilated cardiomyopathy - DCM). Tricuspid annular plane systolic excursion (TAPSE) is a simple, feasible, reality, non-invasive measurement by transthoracic echocardiography for evaluating RV systolic function. Objectives: To evaluate TAPSE in patients with primary or secondary DCM who have left ventricular ejection fraction ≤ 40% and to find the relation between TAPSE and LVEF, LVDd, RVDd, RVDd/LVDd, RA size, severity of TR and PAPs. Materials and Methods: 61 patients (36 males, 59%) mean age 58.6 ± 14.4 years old with clinical signs and symtomps of chronic heart failure which caused by primary or secondary DCM and LVEF ≤ 40% and 30 healthy subject (15 males, 50%) mean age 57.1 ± 16.8 were included in this study. All patients and controls were underwent echocardiographic examination by M-mode, two dimentional, convensional Dopler and TAPSE. Results: TAPSE is significant low in patients compare with the controls (13.93±2.78 mm vs 23.57± 1.60mm, p<0.001). TAPSE is linearly positive correlate with echocardiographic left ventricular ejection fraction (r= 0,43; p<0,001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation was found with LVDd and PAPs. Conclusions: 1. Decreased RV systolic function as estimated by TAPSE in patients with systolic heart failure primary and secondary DCM) compare with controls. 2. TAPSE is linearly positive correlate with LVEF (r= 0.43; p<0.001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation is found with LVDd and PAPs. 3. TAPSE should be used routinely as a simple, feasible, reality method of estimating RV function in the patients systolic heart failure DCM (primary and secondary).

Background The prevalence of undetected left ventricular diastolic dysfunction is high, especially in the elderly with comorbidities. Left ventricular diastolic dysfunction is a prognostic indicator of heart failure, in particularly of heart failure with preserved ejection fraction and of future cardiovascular and all-cause mortality. Therefore we aimed to develop sex-specific diagnostic models to enable the early identification of men and women at high-risk of left ventricular diastolic dysfunction with or without symptoms of heart failure who require more aggressive preventative strategies. Design Individual patient data from four primary care heart failure-screening studies were analysed (1371 participants, excluding patients classified as heart failure and left ventricular ejection fraction <50%). Methods Eleven candidate predictors were entered into logistic regression models to be associated with the presence of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in men and women separately. Internal-external cross-validation was performed to develop and validate the models. Results Increased age and β-blocker therapy remained as predictors in both the models for men and women. The model for men additionally consisted of increased body mass index, moderate to severe shortness of breath, increased pulse pressure and history of ischaemic heart disease. The models performed moderately and similarly well in men (c-statistics range 0.60–0.75) and women (c-statistics range 0.51–0.76) and the performance improved significantly following the addition of N-terminal pro b-type natriuretic peptide (c-statistics range 0.61–0.80 in women and 0.68–0.80 in men). Conclusions We provide an easy-to-use screening tool for use in the community, which can improve the early detection of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in high-risk men and women and optimise tailoring of preventive interventions.

Background: The Heart Failure with Preserved Ejection Fraction (HFpEF) is defined as the preserved left ventricular ejection fraction (LVEF) with the signs of heart failure, elevated natriuretic peptides, and either the evidence of the structural heart disease or diastolic dysfunction. The importance of this form of heart failure was increased after studies where the mortality rates and readmission to the hospital were founded similar as in patients with HF and reduced EF (HFrEF). Coronary microvascular ischemia, cardiomyocyte injury and stiffness could be important factors in the pathophysiology of HFpEF. Methods: The goal of this work is to analyse the relationship of HFpEF and coronary microcirculation in previous studies. Results: The useful diagnostic marker of coronary microcirculation in HFpEF may be the parameters measured by transthoracic echocardiography (TTE), the coronary flow reserve (CFR), as well as fractional flow reserve (FFR) and quantitative myocardial contrast echocardiography (MCE). Cardiac magnetic resonance (CMR) imaging represents the diagnostic gold standard in HFpEF. Coronary microvascular dysfunction in the absence of obstructive coronary artery disease (CAD) is poorly understood and may be more prevalent amongst women than men. Troponin level may be important in risk stratification of HEpEF patients. Conclusion: There are no precise answers with respect to the pathophysiological mechanism, nor are there any precise practical clinical assessment of and diagnostic method for coronary microvascular dysfunction and diastolic dysfunction. In accordance with that, there is no well-established treatment for HFpEF.
