Abstract Background Although some post myocardial infarction (post-MI) and dilated cardiomyopathy (DCM) patients with mid-range ejection fraction heart failure (HFmrEF = 40–49%) face an increased risk for arrhythmic Sudden Cardiac Death (SCD), current guidelines do not recommend an implantable cardioverter-defibrillator (ICD). Purpose To assess the accuracy of a novel multifactorial two-step approach, with noninvasive risk factors (NIRFs) leading to programmed ventricular stimulation (PVS), for SCD risk stratification of hospitalized HFmrEF patients. Methods Forty-eight patients (male=83%, age = 64±14 years, LVEF = 45±5%, ischemic coronary disease = 69%) underwent a NIRF presence screening first step with ECG, SAECG, echocardiography and 24 hour ambulatory ECG (Holter). Thirty-two patients with presence of one out of three NIRFs (SAECG ≥2 positive criteria for late potentials, ventricular premature beats ≥240/24 hours, and ≥1 episode of non-sustained ventricular tachycardia on Holter) were further stratified with PVS. Patients were classified as either low (Group 1, n=16, NIRFs−), moderate (Group 2, n=18, NIRFs+ /PVS−) or high risk (Group 3, n=14, NIRFs+/PVS+). All Group 3 patients received an ICD. Results After 41±18 months, 9 out of 48 patients experienced the major arrhythmic event (MAE) endpoint (clinical ventricular tachycardia/fibrillation = 3, appropriate ICD activation = 6). The endpoint occurred more frequently in Group 3 (7/14, 50%) than in Groups 1 & 2 (2/34, 5.8%). A logistic regression model adjusted for PVS, age and LVEF revealed that PVS was an independent MAE predictor (OR: 21.152, 95% CI: 2.618–170.887, p=0.004). Kaplan Meier curves diverged significantly (p logrank <0.001) while PVS negative predictive value was 94%. Conclusion In hospitalized HFmrEF post-MI and DCM patients, a NIRFs leading to PVS two-step approach efficiently detected the subgroup at increased risk for MAEs.

Galectin 3

For many with heart failure, including the elderly and those with a preserved ejection fraction, both risk stratification and treatment are challenging. For these large populations and others there is increasing recognition of the role of cardiac fibrosis in the pathophysiology of heart failure. Galectin-3 is a novel biomarker of fibrosis and cardiac remodelling that represents an intriguing link between inflammation and fibrosis. In this article we review the biology of galectin-3, recent clinical research and its application in the management of heart failure patients.

Abstract Background The non-invasive assessment of myocardial work (MW) by pressure-strain loops analysis (PSL) is a relative new tool for the evaluation of myocardial performance. Sacubitril/Valsartan is a treatment for heart failure with reduced ejection fraction (HFrEF) which has a spectacular effect on the reduction of cardiovascular events (MACEs). Purposes of this study were to evaluate 1) the short and medium term effect of Sacubitril/Valsartan treatment on MW parameters; 2) the prognostic value of MW in this specific group of patients. Methods 79 patients with HFrEF (mean age: 66±12 years; LV ejection fraction: 28±9%) were prospectively included in the study and treated with Sacubitril/Valsartan. Echocardiographic examination was performed at baseline, and after 6- and 12-month of therapy with Sacubitril/Valsartan. Results Sacubitril/Valsartan significantly increased global myocardial constructive work (CW) (1023±449 vs 1424±484 mmHg%, p<0.0001) and myocardial work efficiency (WE) [87 (78–90) vs 90 (86–95), p<0.0001]. During FU (2.6±0.9 years), MACEs occurred in 13 (16%) patients. After correction for LV size, LVEF and WE, CW was the only predictor of MACEs (Table 1). A CW<910 mmHg (AUC=0.81, p<0.0001, Figure 1A) identified patients at particularly increase risk of MACEs [HR 11.09 (1.45–98.94), p=0.002, log-rank test p<0.0001] (Figure 1 B). Conclusions In patients with HFrEF who receive a comprehensive background beta-blocker and mineral-corticoid receptor antagonist therapy, Sacubitril/Valsartan induces a significant improvement of myocardial CW and WE. In this population, the estimation of CW before the initiation of Sacubitril/Valsartan therapy allows the prediction of MACEs. Funding Acknowledgement Type of funding source: None

Novel Biomarkers

Heart failure (HF) and type 2 diabetes mellitus (T2DM) have a synergistic effect on cardiovascular (CV) morbidity and mortality in patients with established CV disease (CVD). The aim of this review is to summarize the knowledge regarding the discriminative abilities of conventional and novel biomarkers in T2DM patients with established HF or at higher risk of developing HF. While conventional biomarkers, such as natriuretic peptides and high-sensitivity troponins demonstrate high predictive ability in HF with reduced ejection fraction (HFrEF), this is not the case for HF with preserved ejection fraction (HFpEF). HFpEF is a heterogeneous disease with a high variability of CVD and conventional risk factors including T2DM, hypertension, renal disease, older age, and female sex; therefore, the extrapolation of predictive abilities of traditional biomarkers on this population is constrained. New biomarker-based approaches are disputed to be sufficient for improving risk stratification and the prediction of poor clinical outcomes in patients with HFpEF. Novel biomarkers of biomechanical stress, fibrosis, inflammation, oxidative stress, and collagen turn-over have shown potential benefits in determining prognosis in T2DM patients with HF regardless of natriuretic peptides, but their role in point-to-care and in routine practice requires elucidation in large clinical trials.

The identification of prognostic markers in patients with heart failure of both ischemic and non ischemic etiology is an increasing need in the era of devices therapy. Risk stratification for sudden cardiac death (SCD) remains problematic with reliance on left ventricular function which predicts total mortality rather than arrhythmic events (AE). Recently cardiac magnetic resonance was employed to predict susceptibility for malignant arrhythmias. This study sought to determine the utility of late gadolinium enhancement (LGE) to predict AE. Three hundred consecutive patients with symptomatic heart failure and systolic dysfunction of both ischemic and non ischemic cause undergoing CMR, were classified into two groups attending to the presence (n 160) or absence of LGE (n 140), and were followed prospectively during 842 days. The primary endpoint was the combined of SCD or Ventricular tachycardia (VT). 23 patients had AE (8 SCD/15 VT) during the follow-up, 19 of them presenting LGE (83%). The presence of LGE was associated to a significantly higher AE rate (11.8.% vs 2.8% p< 0.001)(figure ). Compared to patients without LGE, midwall fibrosis and an ischemic pattern of LGE predicted AE. (3% vs 5% vs 14%, p= 0.001) LGE is a new non-invasive predictor of AE in patients with heart failure and systolic dysfunction. This suggest a potential role for risk stratification and better selection of patients who needs device therapy

В обзорной статье собраны современные представления об особенностях диагностики и мониторинга пациентов пожилого и старческого возраста с сердечной недостаточностью и стенокардией. Особое внимание уделено проблеме коморбидности пациентов старше 65 лет, что требует корректирующих действий при стратификации риска и прогнозировании клинических исходов. Отмечена приоритетность неинвазивных диагностических тестов. Рекомендована оценка хрупкости как неотъемлемой части диагностического процесса пациентов с сердечной недостаточностью и стенокардией ввиду чёткой связи с худшим прогнозом с точки зрения качества жизни, госпитализации и смертности. Review is about current information on the features of heart failure and angina diagnosis and monitoring in elderly and senile patients. One of the main problem in patients over 65 years is comorbidity, which requires corrective action in the risk stratification and prediction of clinical outcomes. The priority of non-invasive diagnostic tests is noted. Authors of the article recommend frailty as an obligatory part of diagnostic process in patients with heart failure and angina due to a clear connection with the worst prognosis in terms of quality of life, hospitalization and mortality.
