Heart Failure with Preserved Ejection Fraction and Obstructive Sleep Apnea: A Novel Paradigm for Additional Cardiovascular Benefit of SGLT2 Inhibitors in Subjects With or Without Type 2 Diabetes.

After examining the complex interplay between heart failure (HF) in its various clinical forms, metabolic disorders like nonalcoholic fatty liver disease (NAFLD), and obstructive sleep apnea (OSA) syndrome, in this mini-review we described possible favorable effects of sodium-glucose cotransporter 2 inhibitors (SGLT2is) on HF with preserved (i.e., ≥ 50%) ejection fraction (HFpEF) through enhanced cardiorenal function and visceral-subcutaneous body fat redistribution.

Looking for a Tailored Therapy for Heart Failure: Are We Capable of Treating the Patient Instead of the Disease?

After almost a decade of stagnation in clinical research for HF treatment, five large randomized trials recently published have supported the use of four new classes of drugs, namely: angiotensin receptor/neprilysin inhibitor, sodium-glucose co-transporters 2 inhibitors, soluble guanylate cyclase modulators, and myosin activators. Each treatment has proved to be beneficial for both long-term outcomes and quality of life. Beside their clinical relevance, all these novel treatments have a different mechanism of action beyond the usual neuro-hormonal blockage.

Possible Preventative/Rehabilitative Role of Gliflozins in OSA and T2DM. A Systematic Literature Review-Based Hypothesis.

Obstructive sleep apnoea (OSA) is characterized by frequent apnoea episodes during sleep due to upper airway obstruction. The present review summarizes current knowledge on inter-relationships between OSA and type 2 diabetes mellitus (T2DM) and suggests the former as a possible target for sodium-glucose co-transporter-2 inhibitors (SGLT-2i). Based on pathophysiological mechanisms underlying OSA onset and renal SGLT-2 effects, we suggest that SGLT-2i indications might expand beyond current ones, including glucose, lipids, uric acid, blood pressure, and body weight control as well as chronic heart failure and kidney disease prevention.

Differential Role of Circulating microRNAs to Track Progression and Pre-Symptomatic Stage of Chronic Heart Failure: A Pilot Study.

(1)Background: Chronic heart failure (CHF) contributes to the overall burden of cardiovascular disease. Early identification of at-risk individuals may facilitate the targeting of precision therapies. Plasma microRNAs are promising circulating biomarkers for their implications with cardiac pathologies.

Is heart failure misdiagnosed in hospitalized patients with preserved ejection fraction? From the European Society of Cardiology - Heart Failure Association EURObservational Research Programme Heart Failure Long-Term Registry.

Aims: In hospitalized patients with a clinical diagnosis of acute heart failure (HF) with preserved ejection fraction (HFpEF), the aims of this study were (i) to assess the proportion meeting the 2016 European Society of Cardiology (ESC) HFpEF criteria and (ii) to compare patients with restrictive/pseudonormal mitral inflow pattern (MIP) vs. patients with MIP other than restrictive/pseudonormal.

Methods And Results: We included hospitalized participants of the ESC-Heart Failure Association (HFA) EURObservational Research Programme (EORP) HF Long-Term Registry who had echocardiogram with ejection fraction (EF) ≥ 50% during index hospitalization.

Echocardiographic Evaluation of Left Ventricular Output in Patients with Heart Failure: A Per-Beat or Per-Minute Approach?

Background: Left ventricular (LV) output is a predictor of adverse outcome in patients with heart failure. It can be evaluated using a per-beat approach, measuring stroke volume index (SVI), or a per-minute approach, calculating cardiac index (CI). However, the prognostic value of these two approaches has never been compared.

Plasma soluble HLA-G levels in a cohort of heart failure patients exposed to chemicals.

Heart failure (HF) is a syndrome caused by structural and/or functional cardiac abnormalities, resulting in a reduced cardiac output and/or elevated intracardiac pressures. Several studies reported a crucial role of immune activation and inflammation in the chronic heart failure (HF) pathogenesis, suggesting that pro-inflammatory and anti-inflammatory mediators could be predictive markers of the HF development and/or progression. Human Leukocyte Antigen-G (HLA-G), a tolerogenic and anti-inflammatory class I non-classical major histocompatibility complex molecule, was reported to be upregulated in patients diagnosed with HF, suggesting a tentative to regulate the inflammatory condition.

Predicting return to work after acute myocardial infarction: Socio-occupational factors overcome clinical conditions.

Objectives: Return to work after acute myocardial infarction (AMI), a leading cause of death globally, is a multidimensional process influenced by clinical, psychological, social and occupational factors, the single impact of which, however, is still not well defined. The objective of this study was to investigate these 4 factors on return to work (RTW) within 365 days after AMI in a homogeneous cohort of patients who had undergone an urgent coronary angioplasty.

Participants: We studied 102 patients, in employment at the time of AMI (88.

Breathlessness, but not cough, suggests chronic obstructive pulmonary disease in elderly smokers with stable heart failure.

Chronic obstructive pulmonary disease (COPD) is a common comorbidity of heart failure (HF), but remains often undiagnosed, and we aimed to identify symptoms predicting COPD in HF. As part of an observational, prospective study, we investigated stable smokers with a confirmed diagnosis of HF, using the 8-item COPD-Assessment-Test (CAT) questionnaire to assess symptoms. All the items were correlated with the presence of COPD, and logistic regression models were used to identify independent predictors.

Three-Year Hospitalization and Mortality in Elderly Smokers with Chronic Obstructive Pulmonary Disease or Chronic Heart Failure.

Background: In elderly smokers, chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) usually present with dyspnoea. COPD and CHF are associated -almost invariably with concomitant chronic diseases, which contribute to severity and prognosis.

Objectives: We investigated similarities and differences in the clinical presentation, concomitant chronic diseases and risk factors for -mortality and hospitalization at 3-year follow-up in elderly smokers/ex-smokers with a primary diagnosis of COPD or CHF recruited and followed in specialized centers.

[Latest news and perspectives in cardiogenetics].

In recent years, cardiogenetics is emerging as a major discipline for the study of many pathologies, with immediate clinical effects for patients who were previously managed by the cardiologist alone. Recent acquisitions have allowed significant improvements in terms of diagnostic characterization, prognostic stratification and guidance for treatment for both patients with genetic disease and their family members. At present, cardiogenetics has an important role for the clinical management of patients with cardiomyopathies and channelopathies.

Cardiac resynchronization therapy guided by multimodality cardiac imaging.

Aims: Up to 30-45% of implanted patients are non-responders to CRT. We evaluated the role of a 'CRT team' using cardiac magnetic resonance (CMR) and longitudinal myocardial strain to identify the target area defined as the most delayed and viable region for LV pacing.

Methods And Results: A total of 100 heart failure patients candidates for CRT divided into two groups were enrolled.

Serum From Advanced Heart Failure Patients Promotes Angiogenic Sprouting and Affects the Notch Pathway in Human Endothelial Cells.

It is unknown whether components present in heart failure (HF) patients' serum provide an angiogenic stimulus. We sought to determine whether serum from HF patients affects angiogenesis and its major modulator, the Notch pathway, in human umbilical vein endothelial cells (HUVECs). In cells treated with serum from healthy subjects or from patients at different HF stage we determined: (1) Sprouting angiogenesis, by measuring cells network (closed tubes) in collagen gel.

In vitro endothelial cell proliferation assay reveals distinct levels of proangiogenic cytokines characterizing sera of healthy subjects and of patients with heart failure.

Although myocardial angiogenesis is thought to play an important role in heart failure (HF), the involvement of circulating proinflammatory and proangiogenic cytokines in the pathogenesis and/or prognosis of HF has not been deeply investigated. By using a highly standardized proliferation assay with human endothelial cells, we first demonstrated that sera from older (mean age 52 ± 7.6 years; n = 46) healthy donors promoted endothelial cell proliferation to a significantly higher extent compared to sera obtained from younger healthy donors (mean age 29 ± 8.

Echocardiography, spirometry, and systemic acute-phase inflammatory proteins in smokers with COPD or CHF: an observational study.

Chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) may coexist in elderly patients with a history of smoking. Low-grade systemic inflammation induced by smoking may represent the link between these 2 conditions. In this study, we investigated left ventricular dysfunction in patients primarily diagnosed with COPD, and nonreversible airflow limitation in patients primarily diagnosed with CHF.

Plasma sRAGE and N-(carboxymethyl) lysine in patients with CHF and/or COPD.

Background: Knowledge of the role of the receptor for advanced glycation end products (RAGE), particularly its soluble form (sRAGE), and of its advanced glycation end product (AGE) ligand, N-(carboxymethyl)lysine adducts (CML), is limited in chronic heart failure (CHF) and in chronic obstructive pulmonary disease (COPD). We evaluated whether the AGE/RAGE system is activated in stable CHF and COPD, and whether plasma sRAGE and CML levels are affected by clinical and functional parameters.

Materials And Methods: We measured plasma levels of sRAGE and CML using a sandwich enzyme-linked immunosorbent assay (ELISA) in 143 subjects, aged ≥ 65 years, divided into five groups: 58 with CHF, 23 with COPD, 27 with CHF+COPD and 35 controls (17 healthy smokers and 18 healthy nonsmokers).

CCL21 is associated with fatal outcomes in chronic heart failure: data from CORONA and GISSI-HF trials.

Aims: Chronic heart failure (HF) is in part characterized by immune activation and inflammation, and factors that regulate lymphocyte trafficking and inflammation may contribute to the progression of this disorder. The homeostatic chemokine CCL21 is a potent regulator of T-cell migration into non-lymphoid tissue and may exert inflammatory properties and influence tissue remodelling. We therefore investigated CCL21 levels and association with fatal outcomes in patients with chronic HF.

Occurrence and impact of chronic obstructive pulmonary disease in elderly patients with stable heart failure.

Background And Objective: The coexistence of chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) increases with age. The occurrence, prognosis and therapeutic implications of concurrent COPD in elderly patients with CHF were investigated.

Methods: One hundred and eighteen consecutive patients, ≥ 65 years old with ≥ 10 pack/years of smoking and with a verified diagnosis of CHF in stable condition, were enrolled.

Incremental exercise using progressive versus constant pedaling rates: a study in cardiac patients.

Purpose: Cardiopulmonary exercise testing is widely used in clinical assessment and exercise prescription. However, significant differences in physiological responses can occur depending on testing protocol. The aim of this study was to evaluate the cardiopulmonary responses to different incremental cycle pedaling cadences in cardiac patients.

Circulating stem cell vary with NYHA stage in heart failure patients.

We have investigated the blood levels of sub-classes of stem cells (SCs) [mesenchymal stem cells (MSCs), haematopoietic stem cells (HSCs), endothelial progenitor cells/circulating endothelial cells (EPCs/CECs) and tissue-committed stem cells (TCSCs)] in heart failure (HF) patients at different stage of pathology and correlated it with plasmatic levels of proangiogenic cytokines. Peripheral blood level of SCs were analysed in 97 HF patients (24 in NYHA class I, 41 in class II, 17 in class III and 15 in class IV) and in 23 healthy controls. Plasmatic levels of PDGF-BB, bFGF, HGF, vascular endothelial growth factor (VEGF), SDF-1α, TNF-α and NTproBNP were also measured.

Prognostic implications of serial assessments of pulmonary hypertension in severe chronic heart failure.

Background: It is unknown whether time-related changes of pulmonary hypertension (PH) have prognostic relevance in severe chronic heart failure (CHF).

Methods: All CHF patients referred for follow-up from 1996 through 2003 were screened for this study. Eligibility depended on availability of a concomitant clinical, laboratory, electrocardiographic (ECG), echocardiographic and right-heart catheterization (RHC) assessment at index evaluation, as well as absence of pre-capillary PH.

Effects of nebivolol in elderly heart failure patients with or without systolic left ventricular dysfunction: results of the SENIORS echocardiographic substudy.

Aims: The SENIORS trial recently demonstrated that nebivolol reduces the composite risk of all-cause mortality and cardiovascular hospital admission in elderly patients with chronic heart failure and, importantly, that ejection fraction does not influence the clinical effects of nebivolol. An echocardiographic substudy was designed to evaluate the effects of nebivolol on systolic and diastolic left ventricular (LV) function in patients stratified according to the presence or absence of systolic LV dysfunction.

Methods And Results: The substudy randomized 112 patients in 29 European centres, of whom 104 were evaluable for the study; 43 had an ejection fraction (EF) 35%.
