Effects of sacubitril/valsartan on renal function and outcome in patients with heart failure and reduced ejection fraction: an Italian cohort study.

Background: Sacubitril/valsartan (S/V) is a cornerstone treatment for heart failure (HF). Beneficial effects on hospitalization rates, mortality, and left ventricular remodeling have been observed in patients with heart failure and reduced ejection fraction (HFrEF). Despite the positive results, the influence of S/V on renal function during long-term follow-up has received little attention.

Integrated Cardiorespiratory Rehabilitation and Its Impact on Cardio-Renal-Metabolic Profile After Cardiac Surgery.

Background: Cardiovascular diseases (CVDs) and chronic kidney disease (CKD) are common causes of morbidity and mortality. However, the impact of changes in lifestyle and rehabilitation programs on the progression of cardiovascular, renal, and metabolic (CRM) conditions, remains unclear.

Methods: In a retrospective manner, we analyzed charts of 200 patients admitted for cardiorespiratory rehabilitation at our facility in 2023.

Distinct Profiles and New Pharmacological Targets for Heart Failure with Preserved Ejection Fraction.

Background: Heart failure with preserved ejection fraction (HFpEF) is a multifactorial condition with a variety of pathophysiological causes and morphological manifestations. The inclusion criteria and patient classification have become overly simplistic due to the customary differentiation regarding the ejection fraction (EF) cutoff. EF is considered a measure of systolic function; nevertheless, it only represents a portion of the true contractile state and has been shown to have certain limits due to methodological and hemodynamic irregularities.

Right ventricular dysfunction in chronic heart failure: clinical laboratory and echocardiographic characteristics. (the RIVED-CHF registry).

Background: Right ventricular dysfunction (RVD) and pulmonary hypertension have been recognized as two important prognostic features in patients with left side heart failure. Current literature does not distinguish between right heart failure (RHF) and RVD, and the two terms are used indiscriminately to describe pulmonary hypertension and RVD as well as clinical sign of RHF. Therefore, the right ventricle (RV) adaptation across the whole spectrum of left ventricular ejection fraction (LVEF) values has been poorly investigated.

Different right ventricular dysfunction and pulmonary coupling in acute heart failure according to the left ventricular ejection fraction.

Background: Right ventricular (RV) dysfunction and pulmonary uncoupling are two acknowledged features associated with poor outcome, however few data defined RV adaptation across the different left ventricular ejection fraction (EF) cut-off. Additionally, less data are reported in patients with acute heart failure (AHF).

Aims: The aim of present study was to analyse RV function in AHF patients presenting with either reduced or preserved EF.

Pulmonary Artery Systolic Pressure and Cava Vein Status in Acute Heart Failure with Preserved Ejection Fraction: Clinical and Prognostic Implications.

Background: Peak tricuspid regurgitation (TR) velocity and inferior cava vein (ICV) distention are two recognized features of increased pulmonary artery pressure (PASP) and right atrial pressure, respectively. Both parameters are related to pulmonary and systemic congestion and adverse outcomes. However, few data exist about the assessment of PASP and ICV in acute patients affected by heart failure with preserved ejection fraction (HFpEF).

Right heart failure in left heart disease: imaging, functional, and biochemical aspects of right ventricular dysfunction.

For decades, cardiologists have largely underestimated the role of the right heart in heart failure due to left heart disease. Nowadays, the importance of evaluating right ventricular (RV) structure and function in left heart failure is well documented and this concept has been emphasized in the most recent heart failure guidelines. However, several relevant questions remain unanswered such as the following: (a) which imaging technique (standard or 3D echocardiography or strain imaging or cardiac magnetic resonance) and, more, which parameters should be used to grade the severity of RV dysfunction? (b) do less widespread and less applied diagnostic tools such as cardiopulmonary stress testing and bioelectrical impedance analysis play a role in this field? (c) are there specific biochemical aspects of RV failure? (d) why notion of pathophysiology of heart and lung interaction are so well appreciated at an academic level but are not applied in the clinical setting? The present review has been prepared by the Heart Failure (HF) working group of the Italian Society of Cardiology and its main objective is to improve our understanding on RV dysfunction in heart failure.

The Conundrum of HFpEF Definition: Non-Invasive Assessment Uncertainties and Alternative Diagnostic Strategies.

Heart failure (HF) with preserved ejection fraction (HFpEF) is a heterogeneous syndrome including several morphological phenotypes and varying pathophysiological mechanisms. The conventional classification of HF based on left ventricular ejection fraction (LVEF) has created an oversimplification in diagnostic criteria. Although LVEF is a standardized parameter easy to calculate and broadly applied in the large clinical trials, but it is erroneously considered an index of left ventricular (LV) systolic function.

Co-Management of COVID-19 and Heart Failure During the COVID-19 Pandemic: Lessons Learned.

The COVID pandemic has brought many new challenges worldwide, which has impacted on patients with chronic conditions. There is an increasing evidence base suggesting an interaction between chronic heart failure (HF) and COVID-19, and in turn the prognostic impact of co-existence of the two conditions. Patients with existing HF appear more prone to develop severe complications on contracting COVID-19, but the exact prevalence in patients with mild symptoms of COVID-19 not requiring hospital admission is poorly investigated.

Mechanisms of action of SGLT2 inhibitors and their beneficial effects on the cardiorenal axis.

Large clinical studies conducted with sodium-glucose co-transporter 2 inhibitors (SGLT2i) in patients with type 2 diabetes and heart failure with reduced ejection fraction have demonstrated their ability to achieve both cardiac and kidney benefits. Although there is huge evidence on SGLT2i-mediated clinical benefits both in diabetic and non-diabetic patients, the pathophysiological mechanisms underlying their efficacy are still poorly understood. Some favorable mechanisms are likely due to the prompt glycosuric action which is associated with natriuretic effects leading to hemodynamic benefits as well as a reduction in glomerular hyperfiltration and renin-angiotensin-aldosterone system activation.

Usefulness of Combined Renin-Angiotensin System Inhibitors and Diuretic Treatment In Patients Hospitalized with COVID-19.

Antecedent use of renin-angiotensin system inhibitors (RASi) prevents clinical deterioration and protects against cardiovascular/thrombotic complications of COVID-19, for indicated patients. Uncertainty exists regarding treatment continuation throughout infection and doing so with concomitant medications. Hence, the purpose of this study is to evaluate the differential effect of RASi continuation in patients hospitalized with COVID-19 according to diuretic use.

Are HFpEF and HFmrEF So Different? The Need to Understand Distinct Phenotypes.

Traditionally, patients with heart failure (HF) are divided according to ejection fraction (EF) threshold more or <50%. In 2016, the ESC guidelines introduced a new subgroup of HF patients including those subjects with EF ranging between 40 and 49% called heart failure with midrange EF (HFmrEF). This group is poorly represented in clinical trials, and it includes both patients with previous HFrEF having a good response to therapy and subjects with initial preserved EF appearance in which systolic function has been impaired.

Nomenclature for Kidney Function from KDIGO: Shortcomings of Terminology Oversimplification.

The recent Kidney Disease: Improving Global Outcomes (KDIGO) consensus conference proposed a universal nomenclature calling for "Kidney Disease" (KD) to be applied to every form of kidney dysfunction, regardless of etiology. We recognize that the estimated glomerular filtration rate and urine albumin:creatinine ratio are limited in their application to the broad spectrum of KD. However, there are additional in vitro and advanced diagnostic options that can help identify the underlying cause of KD and inform about prognosis and management.

Antecedent Administration of Angiotensin-Converting Enzyme Inhibitors or Angiotensin II Receptor Antagonists and Survival After Hospitalization for COVID-19 Syndrome.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilizes the angiotensin-converting enzyme-2 (ACE-2) receptor to enter human cells. Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor antagonists (ARB) are associated with ACE-2 upregulation. We hypothesized that antecedent use of ACEI/ARB may be associated with mortality in coronavirus disease 2019 (COVID-19).

Myocardial phenotypes and dysfunction in HFpEF and HFrEF assessed by echocardiography and cardiac magnetic resonance.

Heart failure (HF) with either reduced or preserved ejection fraction is an increasingly prevalent condition. Cardiac imaging plays a central role in trying to identify the underlying cause of the underlying systolic and diastolic dysfunction, as the imaging findings have implications for patient's management and individualised treatment. The imaging modalities used more frequently in patients with heart failure in clinical routine are echocardiography and cardiac magnetic resonance.

Molecular Dysfunction and Phenotypic Derangement in Diabetic Cardiomyopathy.

The high incidence and poor prognosis of heart failure (HF) patients affected with diabetes (DM) is in part related to a specific cardiac remodeling currently recognized as diabetic cardiomyopathy (DCM). This cardiac frame occurs regardless of the presence of coronary artery diseases (CAD) and it can account for 15-20% of the total diabetic population. The pathogenesis of DCM remains controversial, and several molecular and cellular alterations including myocardial hypertrophy, interstitial fibrosis, oxidative stress and vascular inflammation, have been postulated.

Comparison of Neutrophil Gelatinase-Associated Lipocalin Versus B-Type Natriuretic Peptide and Cystatin C to Predict Early Acute Kidney Injury and Outcome in Patients With Acute Heart Failure.

Neutrophil gelatinase-associated lipocalin (NGAL) has been described in chronic heart failure (HF) as marker of tubular damage and renal dysfunction; however, less data are available in patients with acute HF. Because of high rate of acute kidney injury (AKI) development, we aimed to investigate the role of NGAL in predicting early AKI development; second, we compared NGAL with respect to cystatin C, B-type natriuretic peptide (BNP), renal function, and blood urea nitrogen (BUN) for outcome prediction. We measured admission serum NGAL, cystatin C, and BNP in 231 patients affected to acute HF; all patients were submitted to daily creatinine, estimated glomerular filtration rate, and measurement to identify inhospital AKI defined by Risk, Injury, Failure, Loss, End-Stage Kidney Disease and Acute Kidney Injury Network criteria.
