RESUMEN
BACKGROUND: Worsening Heart Failure (WHF) is associated with adverse prognosis. Identifying novel prognostic markers in WHF is crucial. Gait speed (GS), a validated frailty index, is an easily obtainable parameter that may aid in reclassifying the risk of HF patients. We assessed the independent prognostic role of GS in WHF patients. METHODS: We studied 171 patients with chronic HF with worsening congestion symptoms and inadequate response to standard therapies, requiring intravenous diuretic treatment. The primary outcome was a composite of all-cause mortality or HF hospitalization. We assessed the association and the incremental value of GS, as compared to other clinical confounders, with the primary outcome. RESULTS: The mean age was 76±11 years, 66 % were male, median BNP was 481 pg/ml, and median ejection fraction was 40 %. Over a median follow-up of 11.3 months, 71 events occurred. Lower GS was significantly associated with a higher risk of events (HR of 4.03, 95 % CI 2.25-7.21), along with neutrophil to lymphocyte ratio, BNP, QRS duration, natremia, and previous myocardial infarction. When added to the MAGGIC risk score and the other significant confounders identified, GS significantly enhanced the model risk prediction (Harrell's C-index 0.75 vs 0.71, p < 0.001). At Classification And Regression Tree analysis, GS≤0.8 m/s was the first parameter to be considered to risk stratify the population. CONCLUSIONS: GS, an easily obtainable marker of frailty, may contribute to improve the risk stratification of patients with WHF.
RESUMEN
AIMS: The identification of subjects at higher risk for incident heart failure (HF) with preserved ejection fraction (EF) suitable for more intensive preventive programmes remains challenging. We applied phenomapping to the DAVID-Berg population, comprising subjects with preclinical HF, aiming to refine HF risk stratification. METHODS: The DAVID-Berg study prospectively enrolled 596 asymptomatic outpatients with EF > 40% with hypertension, diabetes mellitus or known cardiovascular disease. In this cohort, we performed an unsupervised cluster analysis on 591 patients, including clinical, laboratory, electrocardiographic and echocardiographic parameters. We tested the association between each cluster and a composite outcome of HF/death. RESULTS: The median age was 70 years, 55.5% were males and the median EF was 61.0%. Phenomapping provided three different clusters. Subjects in Cluster 3 were the oldest and had the highest prevalence of atrial fibrillation, the lowest estimated glomerular filtration rate (eGFR), the highest N-terminal pro-brain natriuretic peptide (NT-proBNP) and the largest left atrium. During a median follow-up of 5.7 years, 13.4% of subjects experienced HF/death events (N = 79). Compared with Clusters 1 and 2, Cluster 3 had the worst prognosis (log-rank test: Cluster 3 vs. 1 P < 0.001; Cluster 3 vs. 2 P = 0.008). Cluster 3 was associated with a risk of HF/death 2.5 times higher than Cluster 1 [adjusted hazard ratio (HR) = 2.46, 95% confidence interval (CI) 1.24-4.90]. CONCLUSIONS: Based on phenomapping, older patients with lower kidney function and worse diastolic function might represent a subset of preclinical HF with EF > 40% who deserve more efforts to prevent clinical HF.
RESUMEN
AIMS: Cardiovascular-kidney-metabolic (CKM) multimorbidity is prevalent among individuals with heart failure (HF), but whether cardiac structure and function, clinical outcomes, and treatment response to sacubitril/valsartan vary in relation to CKM status is unknown. METHODS AND RESULTS: In this PARAGON-HF post-hoc analysis, we evaluated the impact of CKM multimorbidity (atherosclerotic cardiovascular [CV] disease, chronic kidney disease, and type 2 diabetes) on cardiac structure and function, clinical outcomes, and treatment effects of sacubitril/valsartan versus valsartan. The primary outcome was a composite of total HF hospitalizations and CV death. Secondary outcomes included the individual components of the primary outcome and a composite kidney outcome (sustained estimated glomerular filtration rate reduction of ≥50%, end-stage kidney disease, or kidney-related death). At baseline, 35.2% had one CKM condition, 33.3% had two, 15.9% had three, and only 15.6% had HF alone. CKM multimorbidity was associated with higher septal and posterior wall thickness, lower global longitudinal strain, higher E/e', and worse right ventricular function. Total HF hospitalizations or CV death increased with greater CKM multimorbidity, with the highest relative risk observed with three CKM conditions (rate ratio 3.06, 95% confidence interval 2.33-4.03), compared with HF alone. Treatment effects of sacubitril/valsartan were consistent irrespective of the number of CKM conditions for the primary endpoint (pinteraction = 0.75), CV death (pinteraction = 0.82), total HF hospitalizations (pinteraction = 0.67), and the composite kidney endpoint (pinteraction = 0.99). CONCLUSIONS: Cardiovascular-kidney-metabolic multimorbidity was common in PARAGON-HF and associated with adverse changes in cardiac structure and function and with a stepwise increase in risk of clinical outcomes. Treatment effects of sacubitril/valsartan were consistent irrespective of CKM burden. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT01920711.
RESUMEN
Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome characterised by the presence of diastolic dysfunction and elevated left ventricular filling pressure, in the setting of a left ventricular ejection fraction of at least 50%. Despite the epidemiological prevalence of HFpEF, a prompt diagnosis is challenging and many uncertainties exist. HFpEF is characterised by different phenotypes driven by various cardiac and non-cardiac comorbidities. This is probably the reason why several HFpEF clinical trials in the past did not reach strong outcomes to recommend a single therapy for this syndrome; however, this paradigm has recently changed, and the unmet clinical need for HFpEF treatment found a proper response as a result of a new class of drug, the sodium-glucose cotransporter 2 inhibitors, which beneficially act through the whole spectrum of left ventricular ejection fraction. The aim of this review was to focus on the therapeutic target of HFpEF, the role of new drugs and the potential role of new devices to manage the syndrome.
RESUMEN
Obesity is a chronic and relapsing disease characterized by the interaction between individual predispositions and an obesogenic environment. Recent advances in understanding the mechanisms of energetic homoeostasis paved the way to more effective therapeutic approaches compared with traditional treatments. Since obesity is a complex disease, it necessitates a multi-disciplinary approach whose implementation remains challenging. Nonetheless, emerging pharmacological interventions appear promising. Currently, therapeutic success is discreet in the short term but often fails to maintain long-term weight loss due to a high likelihood of weight regain. Cardiologists play a key role in managing patients with obesity, yet often lack familiarity with its comprehensive management. The aim of this document is to summarize knowledge to consolidate essential knowledge for clinicians to effectively treat patients living with obesity. The paper emphasizes the pivotal role of a strong patient-clinician relationship in navigating successful treatment. We analyse the criteria commonly used to diagnose obesity and point out the strengths and limitations of different criteria. Furthermore, we discuss the role of obesiologists and the contributions of cardiologists. In addition, we detail key components of effective therapeutic strategies, including educational aspects and pharmacological options.
RESUMEN
The Italian Network on Congestive Heart Failure (IN-CHF) project, later known as IN-HF Online, was launched in 1995 to provide the Italian cardiology community with a digital tool, standardized across the country, for managing outpatients with heart failure (HF), that enabled the creation of a database for clinical, educational and scientific purposes. During its almost three decades of activity, this observational research program has achieved highly positive scientific results. Indeed, IN-HF fostered professional relationships among individuals working in different centers, established a cultural network for the care of HF patients, periodically updated on the scientific advances, and allowed the assessment of several clinical, epidemiological, and prognostic features. These findings have been published in numerous national and international journals, as summarized in the present overview.

Obesity is a chronic and relapsing disease due to the coexistence of a patient with predisposing individual characteristics and an obesogenic environment. The recent acquisition of detailed knowledge on the mechanisms underlying the energetic homeostasis paved the way to more effective therapeutic hypotheses as compared to traditional treatments. Since obesity is a complex issue, it requires a multidisciplinary approach which is difficult to implement. However, new drugs appear promising. Currently, therapeutic success is discrete in the short term, but unsatisfying in the long term due to the high probability of body weight gain. Cardiologists play a key role in managing patients with obesity, but they are not used to manage them. The aim of this document is to summarize knowledge that clinicians need to have to appropriately manage these patients. The paper emphasizes the pivotal role of an appropriate relationship with the patient to embark on a successful treatment journey. We analyze the criteria commonly used to diagnose obesity and point out strengths and limitations of different criteria. Furthermore, we discuss the figure of the obesitologist and the role of the cardiologist. In addition, we report the main components of an effective therapeutic strategy, from educational questions to pharmacological options.

Heart failure with preserved ejection fraction (HFpEF) is characterized by a notable heterogeneity in both phenotypic and pathophysiological features, with a growing incidence due to the increase in median age and comorbidities such as obesity, arterial hypertension, and cardiometabolic disease. In recent decades, the development of new pharmacological and non-pharmacological options has significantly impacted outcomes, improving clinical status and reducing mortality. Moreover, a more personalized and accurate therapeutic management has been demonstrated to enhance the quality of life, diminish hospitalizations, and improve overall survival. Therefore, assessing the peculiarities of patients with HFpEF is crucial in order to obtain a better understanding of this disorder. Importantly, comorbidities have been shown to influence symptoms and prognosis, and, consequently, they should be carefully addressed. In this sense, it is mandatory to join forces with a multidisciplinary team in order to achieve high-quality care. However, HFpEF remains largely under-recognized and under-treated in clinical practice, and the diagnostic and therapeutic management of these patients remains challenging. The aim of this paper is to articulate a pragmatic approach for patients with HFpEF focusing on the etiology, diagnosis, and treatment of HFpEF.
RESUMEN
BACKGROUND: Available data on the clinical characteristics and prognosis of patients with heart failure (HF) due to dilated cardiomyopathy (DCM) derive mainly from tertiary care centres for cardiomyopathies or from drug trial sub-studies, which may entail a referral bias. METHODS: From 2008 to 2021, we enrolled in a nationwide HF Registry 1886 DCM patients and 3899 with ischemic heart disease (IHD). RESULTS: Patients with DCM were younger, more often female, had more commonly recent onset HF, left bundle branch block, and showed higher LV end-diastolic volume and lower LVEF than IHD. With respect to IHD, DCM patients received more often mineralocorticoid receptor antagonists, renin angiotensin system inhibitors and betablockers, the latter more commonly at doses ≥50% of target, and triple guideline-directed medical therapy (GDMT) (adjusted OR 1.411, 95% CI 1.247-1.595, p < .0001). During one-year follow-up, 819 patients (14.2%) died or were hospitalized for HF [187 (9.9%) DCM, 632 (16.2%) IHD]; DCM was associated with lower risk of the combined end-point (adjusted HR 0.745, 95% CI 0.625- 0.888, p = .0011). Among the 1954 patients with 1-year echocardiograms available, 1483 had LVEF≤40% at baseline; of these,166 (30.6%) DCM and 165 (17.5%) IHD improved their LVEF to >40% (p < .0001). DCM aetiology was associated with higher likelihood of LVEF improvement (adjusted OR 1.722, 95% CI 1.328 -2.233, p < .0001). CONCLUSIONS: DCM patients have a different clinical profile, greater uptake of GDMT and better outcomes than IHD subjects. A comprehensive management approach is needed to further address the risk of unfavorable outcomes in DCM.

Pulmonary hypertension (PH) is a common complication of diseases affecting the left heart, mostly found in patients suffering from heart failure. Left atrial hypertension is the initial driver of post-capillary PH. However, several mechanisms may lead in a subset of patients to structural changes in the pulmonary vessels with development of a pre-capillary component. The right ventricle may be frequently affected, leading to right ventricular failure and a worse outcome. The differential diagnosis of PH associated with left heart disease vs pulmonary arterial hypertension (PAH) is challenging in patients with cardiovascular comorbidities, risk factors for PAH and/or a preserved left ventricular ejection fraction. Multidimensional clinical phenotyping is needed to identify patients in whom hemodynamic confirmation is deemed necessary, that may be completed by provocative testing in the cath lab. In contrast with PAH, management of PH associated with left heart disease should focus on the treatment of the underlying condition. There is currently no approved therapy for PH associated with left heart disease: some PAH-specific treatments have led to an increase in adverse events in these patients.

Hyperkalaemia is one of the most common electrolyte disorders in patients with cardiovascular disease (CVD). The true burden of hyperkalaemia in the real-world setting can be difficult to assess, but in population-based cohort studies up to 4 in 10 patients developed hyperkalaemia. In addition to drugs interfering with potassium metabolism and food intake, several conditions can cause or worsen hyperkalaemia, such as advanced age, diabetes, and chronic kidney disease. Mortality, cardiovascular morbidity, and hospitalisation are higher in patients with hyperkalaemia. Hyperkalaemia represents a major contraindication or a withholding cause for disease-modifying therapies like renin-angiotensin-aldosterone inhibitors (RAASi), mainly mineralocorticoid receptor antagonists. Hyperkalaemia can be also classified as acute and chronic, according to the onset. Acute hyperkalaemia is often a life-threatening emergency requiring immediate treatment to avoid lethal arrhythmias. Therapy goal is cell membrane stabilisation by calcium administration, cellular intake, shift of extracellular potassium to the intracellular space (insulin, beta-adrenergic agents, sodium bicarbonate), and increased elimination with diuretics or dialysis. Chronic hyperkalaemia was often managed with dietary counselling to prevent potassium-rich food intake and tapering of potassium-increasing drugs, mostly RAASi. Sodium polystyrene sulphonate, a potassium binder, was the only therapeutic option. Recently, new drugs such as patiromer and sodium zirconium cyclosilicate give new opportunities for the treatment of hyperkalaemia, as they proved to be safe, well tolerated, and effective. Aim of this review is to describe the burden of hyperkalaemia in cardiovascular patients, its direct and indirect effects, and the therapeutic options now available in the acute and chronic setting.
RESUMEN
Diagnosis of heart failure with preserved ejection fraction (HFpEF) can be challenging and it could require different tests, some of which are affected by limited availability. Nowadays, considering that new therapies are available for HFpEF and related conditions, a prompt and correct diagnosis is relevant. However, the diagnostic role of biomarker level, imaging tools, score-based algorithms and invasive evaluation, should be based on the strengths and weaknesses of each test. The aim of this review is to help the clinician in diagnosing HFpEF, overcoming the diagnostic uncertainty and disentangling among the different underlying causes, in order to properly treat this kind of patient.

Myeloproliferative neoplasms, including polycythemia vera, essential thrombocythemia, and myelofibrosis, are characterized by somatic gene mutations in bone marrow stem cells, which trigger an inflammatory response influencing the development of associated cardiovascular complications. In recent years, the same mutations were found in individuals with cardiovascular diseases even in the absence of hematological alterations. These genetic events allow the identification of a new entity called 'clonal hematopoiesis of indeterminate potential' (CHIP), as it was uncertain whether it could evolve toward hematological malignancies. CHIP is age-related and, remarkably, myocardial infarction, stroke, and heart failure were frequently reported in these individuals and attributed to systemic chronic inflammation driven by the genetic mutation. We reviewed the connection between clonal hematopoiesis, inflammation, and cardiovascular diseases, with a practical approach to improve clinical practice and highlight the current unmet needs in this area of knowledge.

Background: Sodium nitroprusside (SNP) is an excellent drug in acute decompensated heart failure (HF) patients with high vascular peripheral resistance. Its prolonged administration may cause thiocyanate accumulation and toxicity. A proarrhythmic side effect has never been reported. Case summary: Herein, we report a case of an adult male affected by advanced HF due to a valvular cardiomyopathy admitted to our intensive cardiology unit with severe decompensation and waiting for a heart transplant. He was treated for several weeks with high-dose SNP, due to severe pulmonary hypertension and an extremely labile haemodynamic profile. He progressively developed high thiocyanate levels and, concomitantly, free calcium ion depletion, despite normal total calcium levels, with iterative ventricular arrhythmias. Calcium ion depletion was not responsive to calcium supplementation. We suspected a causative role of thiocyanate since the negatively charged sulfur atom of the thiocyanate molecules could bind the positively charged free calcium ions, leading to a free calcium ion depletion. Thus, we cautiously reduced SNP dosage, according to the patient's haemodynamic profile, with concomitant progressive free calcium ion normalization, thus reducing the arrhythmic burden of the patient, being able to finally perform heart transplantation. Conclusion: We describe for the first time a proarrhythmic side effect of prolonged SNP administration, namely, calcium ion depletion, likely related to thiocyanate toxicity. Despite aggressive calcium supplementation, the only way to reduce the arrhythmic burden was SNP down titration.
RESUMEN
Randomised clinical trials, observational studies, and meta-analyses have shown that sodium-glucose cotransporter 2 inhibitors (SGLT2-i) reduce the risk of hospitalisation for heart failure (HF), chronic kidney disease (CKD) progression, and mortality in patients with HF, irrespective of the presence of type 2 diabetes mellitus. However, real-world epidemiology may differ from clinical trial populations, thereby limiting generalisability and delaying the introduction of novel treatments in clinical practice.The aim of the present study was to assess the prevalence of DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) inclusion criteria in a population of HF with reduced ejection fraction (HFrEF) patients enrolled in the Italian Network on Heart Failure (IN-HF) registry.Overall, 3415 IN-HF patients matched the 4744 patients in DAPA-HF, overlapping for most baseline characteristics (e.g. similar average ejection fraction), with a slightly lower prevalence of type 2 diabetes and of HF ischaemic aetiology and a higher percentage of NYHA class II patients. The theoretical eligibility to DAPA-HF in a cardiology setting resulted to be 73%.The availability of an easily accessible database from a large nationwide prospective registry allows to provide insights to clinicians and policy makers on the applicability of the DAPA HF findings to a contemporary population of HFrEF patients followed by cardiologists. It is reasonable to assume that the results of this analysis can be applicable to the entire SGLT2-ir class of drugs.

In recent years, there has been growing interest in the risk stratification for heart failure, and the use of multiple biomarkers to identify different pathophysiological processes associated with this condition. One such biomarker is soluble suppression of tumorigenicity-2 (sST2), which has shown some potential for integration into clinical practice. sST2 is produced by both cardiac fibroblasts and cardiomyocytes in response to myocardial stress. Other sources of sST2 are endothelial cells of the aorta and coronary arteries and immune cells such as T cells. Indeed, ST2 is also associated with inflammatory and immune processes. We aimed at reviewing the prognostic value of sST2 in both chronic and acute heart failure. In this setting, we also provide a flowchart about its potential use in clinical practice.
RESUMEN
Background: Heart failure with preserved ejection fraction (HFpEF) is very frequently associated to sleep breathing disorders (SDB). Red blood cell distribution width (RDW) has been shown to be a potential inflammatory index linked to the degree of hypoxia and oxidative stress. Aim: To identify the existence of a possible relationship between sleep apnea, oxygen saturation (SaO2) and RDW in a population of subjects affected by acute HFpEF (AHFpEF). Methods: AHFpEF patients with known history of SDB were enrolled and performed blood chemistry, echocardiography, and 24-h polysomnography (PSG). Results: A total of 34 acute HFpEF patients (mean age 72.8 +/-8.63) were enrolled in the study. A control group of 24 non-HF patients were considered. Compared to controls, HFpEF patients showed a higher mean apnea hypopnea index (AHI), with prevalence of central apneas. A moderate to severe desaturation pattern was observed in AHFpEF vs. controls. RDW was significantly higher in AHFpEF patients vs. controls (mean value 14.7 +/-2.6 % vs. 9.1 +/-2.2, p < 0.05). In AHFpEF, RDW showed a positive correlation with time of SaO2 < 90% (r = 0.35, p = 0.04), and with mean length of apneic events (60 +/-28 s, r = 0.29, p = 0.03). Conclusion: In patients with AHFpEF and SDB, a dependence relationship between RDW and duration of oxygen desaturation was observed, as if oxidative stress and inflammation related to RDW increase could also be linked to severity of sleep disorders in this population.
RESUMEN
BACKGROUND: In patients with pneumonia or acute respiratory distress syndrome who survived hospitalization, one-year mortality can affect up to one third of discharged patients. Therefore, significant long-term mortality after COVID-19 respiratory failure could be expected. The primary outcome of the present study was one-year all-cause mortality in hospitalized COVID-19 patients. METHODS: Observational study of COVID-19 patients hospitalized at Papa Giovanni XXIII Hospital (Bergamo, Italy), during the first pandemic wave. RESULTS: A total of 1326 COVID-19 patients were hospitalized. Overall one-year mortality was 33.6% (N 446/1326), with the majority of deaths occurring during hospitalization (N=412, 92.4%). Thirty-four patients amongst the 914 discharged (3.7%) subsequentely died within one year. A third of these patients died for advanced cancer, while death without a cause other than COVID-19 was uncommon (8.8% of the overall post-discharge mortality). In-hospital late mortality (i.e. after 28 days of admission) interested a population with a lower age, and fewer comorbidities, more frequentely admitted in ICU. Independent predictors of post-discharge mortality were age over 65 years (HR 3.19; 95% CI 1.28-7.96, p-value=0.013), presence of chronic obstructive pulmonary disease (COPD) (HR 2.52; 95% CI 1.09-5.83, p-value=0.031) or proxy of cardiovascular disease (HR 4.93; 95% CI 1.45-16.75, p-value=0.010), and presence of active cancer (HR 3.64; 95% CI 1.50-8.84, p-value=0.004), but not pneumonia severity. CONCLUSIONS: One-year post-discharge mortality depends on underlying patients' comorbidities rather than COVID-19 pneumonia severity per se. Awareness among physicians of predictors of post-discharge mortality might be helpful in structuring a follow-up program for discharged patients.

Cardiac magnetic resonance (CMR) imaging has progressively become part of the imaging methods recommended in patients with heart failure. CMR represents the gold standard for assessing volumes, function, biventricular kinetics and providing tissue characterization through scans with and without contrast medium. In patients with heart failure with reduced ejection fraction (HFrEF) and ischemic dilated cardiomyopathy, CMR allows to search for viability, accurately estimate volumes and ejection fraction. It can assess scar extent for predicting response to cardiac resynchronization therapy and for establishing an indication for implanting a defibrillator in borderline cases. In patients with HFrEF and non-ischemic dilated cardiomyopathy, CMR helps to identify specific etiological subgroups and to estimate the arrhythmic risk beyond ejection fraction. In patients with heart failure with preserved ejection fraction, CMR offers the possibility of diagnosing specific phenotypes, including sarcomeric hypertrophic cardiomyopathy, amyloidosis or Fabry disease, and adds prognostic information. Both clinical and scientific interest in this imaging method is constantly expanding; the clinicians dealing with heart failure cannot fail to know the technique, the indications and all the potential that CMR can offer.
