ANMCO POSITION PAPER: Role of intra-aortic balloon pump in patients with acute advanced heart failure and cardiogenic shock.

The treatment of patients with advanced acute heart failure is still challenging. Intra-aortic balloon pump (IABP) has widely been used in the management of patients with cardiogenic shock. However, according to international guidelines, its routinary use in patients with cardiogenic shock is not recommended. This recommendation is derived from the results of the IABP-SHOCK II trial, which demonstrated that IABP does not reduce all-cause mortality in patients with acute myocardial infarction and cardiogenic shock. The present position paper, released by the Italian Association of Hospital Cardiologists, reviews the available data derived from clinical studies. It also provides practical recommendations for the optimal use of IABP in the treatment of cardiogenic shock and advanced acute heart failure.

Maximal efficiency is required to minimize complications and hospital stay after TAVR.

When TAVR is performed with transfemoral percutaneous approach, local anesthesia, no routine post-procedural intensive care admission, an early discharge (<3 days) can be adopted in most TAVR patients Avoiding peri-procedural complications and minimizing pace-maker implantation rate are key to allow early patient discharge When properly selected, patients discharged early have low discharge have low risk of adverse events and readmissions in the first 30 days.

Unexpected delayed complete atrioventricular block after Cardioband implantation.

The Cardioband system is a transcatheter direct annuloplasty device that is implanted in patients with severe symptomatic functional mitral regurgitation (MR) due to annulus dilatation and high surgical risk. This device covers the posterior two-thirds of the annulus, from the anterolateral to the posteromedial commissure, implanted in close proximity of the left circumflex artery, atrioventricular (AV) conduction system, and coronary sinus. We present the case of an 80-year-old-gentleman with prohibitive surgical risk, treated with Cardioband implantation for functional MR with an evident P1-P2 cleft and P2-P3 indentation, a relative contraindication to MitraClip implantation. We achieved procedural success with significative mitral annulus reduction (30% anteroposterior reduction from 37 to 26 mm) and MR reduction (from grade 4 to grade 1-2). A late onset Mobitz 2 AV block developed after 26 hr and evolved to complete AV block in the following day, requiring definitive biventricular pacemaker (PM). Less than 200 Cardioband implantations have been performed but, to our knowledge, this is the first reported AV block, possibly facilitated by the pre-existing bifascicular block, suggesting the opportunity of prolonged ECG monitoring after Cardioband like any other mechanical transcatheter structural intervention possibly affecting the AV conduction system.

[Blood gas analysis in the intensive cardiac care unit]. / La rapida lettura dell'emogasanalisi in unità di terapia intensiva cardiologica.

Arterial blood gas (ABG) analysis is a simple and quick test that can provide multiple respiratory and metabolic parameters. The interpretation of ABG analysis and acid-base disorders represents one of the most complex chapters of clinical medicine. In this brief review, the authors propose a rational approach that sequentially analyzes the information offered by the ABG to allow a rapid classification of the respiratory, metabolic or mixed disorder. The patient's history and clinical-instrumental assessment are the framework in which to insert the information derived from the ABG analysis in order to characterize the critical heart patient.

Dapagliflozin Effects on Cardiac Deformation in Heart Failure and Secondary Clinical Outcome.

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors were shown to reduce morbidity and mortality in patients with heart failure. OBJECTIVES: This study aims to assess potential effects of dapagliflozin in nondiabetic patients with heart failure with reduced ejection fraction (HFrEF) and heart failure with mildly reduced ejection fraction (HFmrEF) on cardiac function assessed by speckle tracking echocardiography (STE). METHODS: This randomized, prospective, single-center, open-label trial compared consecutive nondiabetic outpatients with HFrEF or HFmrEF receiving dapagliflozin with patients treated with optimal medical therapy (OMT) except sodium-glucose cotransporter type 2 inhibitors. Primary endpoint was the presence of a significant modification of left ventricular global longitudinal strain, diastolic function (as peak atrial longitudinal strain) and right ventricular function by STE from baseline to 6 months. Cardiovascular events and parameters of congestion were assessed as safety-exploratory endpoints. RESULTS: Overall, 88 patients (38% HFmrEF) were enrolled and randomized to start dapagliflozin on top of OMT (n = 44) or to continue with OMT (n = 44). All STE values improved in the dapagliflozin group after 6 months, whereas there was a nonsignificant improvement in OMT group. Moreover, when comparing the modification of STE parameters at follow-up in patients with HFrEF and HFmrEF, only the main treatment effect resulted statistically significant in both groups (P < 0.0001), indicating a significant difference between dapagliflozin and OMT. CONCLUSIONS: This study provided randomized data on the beneficial effect of dapagliflozin in nondiabetic patients with HFrEF and HFmrEF in terms of myocardial performance measured by the most sensitive echocardiographic technique, ie, STE. This suggests its usefulness for left ventricular reverse remodeling and better quality of life in patients with HFrEF and HFmrEF.

Takotsubo Syndrome and Gender Differences: Exploring Pathophysiological Mechanisms and Clinical Differences for a Personalized Approach in Patient Management.

Takotsubo syndrome (TTS), also known as the broken-heart syndrome, is a reversible condition typically observed in female patients presenting for acute coronary syndromes (ACS). Despite its increasing incidence, TTS often remains undiagnosed due to its overlap with ACS. The pathophysiology of TTS is complex and involves factors such as coronary vasospasm, microcirculatory dysfunction, increased catecholamine levels, and overactivity of the sympathetic nervous system. Diagnosing TTS requires a comprehensive approach, starting with clinical suspicion and progressing to both non-invasive and invasive multimodal tests guided by a specific diagnostic algorithm. Management of TTS should be personalized, considering potential complications, the presence or absence of coronary artery disease (CAD), diagnostic test results, and the patient's clinical course. The current data primarily derive from case series, retrospective analyses, prospective registries, and expert opinions. In recent years, there has been growing recognition of gender differences in the pathophysiology, presentation, and outcomes of TTS. This review provides an updated overview of gender disparities, highlighting the importance of tailored diagnostic and management strategies.

Aspirin in Primary Prevention: Looking for Those Who Enjoy It.

Based on a wealth of evidence, aspirin is one of the cornerstones of secondary prevention of cardiovascular disease. However, despite several studies showing efficacy also in primary prevention, an unopposed excess risk of bleeding leading to a very thin safety margin is evident in subjects without a clear acute cardiovascular event. Overall, the variability in recommendations from different scientific societies for aspirin use in primary prevention is a classic example of failure of simple risk stratification models based on competing risks (atherothrombosis vs. bleeding), perceived to be opposed but intertwined at the pathophysiological level. Notably, cardiovascular risk is dynamic in nature and cannot be accurately captured by scores, which do not always consider risk enhancers. Furthermore, the widespread use of other potent medications in primary prevention, such as lipid-lowering and anti-hypertensive drugs, might be reducing the benefit of aspirin in recent trials. Some authors, drawing from specific pathophysiological data, have suggested that specific subgroups might benefit more from aspirin. This includes patients with diabetes and those with obesity; sex-based differences are considered as well. Moreover, molecular analysis of platelet reactivity has been proposed. A beneficial effect of aspirin has also been demonstrated for the prevention of cancer, especially colorectal. This review explores evidence and controversies concerning the use of aspirin in primary prevention, considering new perspectives in order to provide a comprehensive individualized approach.

Ventilation strategies in cardiogenic shock: Insights from the AltShock-2 registry.

AIMS: To describe the use and the relation to outcome of different ventilation strategies in a contemporary, large, prospective registry of cardiogenic shock patients. METHODS AND RESULTS: Among 657 patients enrolled from March 2020 to November 2023, 198 (30.1%) received oxygen therapy (OT), 96 (14.6%) underwent non-invasive ventilation (NIV), and 363 (55.3%) underwent invasive mechanical ventilation (iMV). Patients in the iMV group were significantly younger compared to those in the NIV and OT groups (63 vs. 69 years, p < 0.001). There were no significant differences between groups regarding cardiovascular risk factors. Patients with SCAI B and C were more frequently treated with OT and NIV compared to iMV (65.1% and 65.4% vs. 42.6%, respectively, p > 0.001), while the opposite trend was observed in SCAI D patients (12% and 12.2% vs. 30.9%, respectively, p < 0.001). All-cause mortality at 24 h did not differ amongst the three groups. The 60-day mortality rates were 40.2% for the iMV group, 26% for the OT group, and 29.3% for the NIV group (p = 0.005), even after excluding patients with cardiac arrest at presentation. In the multivariate analysis including SCAI stages, NIV was not associated with worse mortality compared to iMV (hazard ratio 1.97, 95% confidence interval 0.85-4.56), even in more severe SCAI stages such as D. CONCLUSIONS: Compared to previous studies, we observed a rising trend in the utilization of NIV among cardiogenic shock patients, irrespective of aetiology and SCAI stages. In this clinical scenario, NIV emerges as a safe option for appropriately selected patients.

[Circulatory shock: early diagnosis and therapy]. / Shock circolatorio: diagnosi e terapia precoce.

Circulatory shock is a clinical condition characterized by hypotension and organ hypoperfusion, potentially fatal if the underlying cause is not promptly identified and corrected. Circulatory shock outcome is certainly conditioned from early diagnosis and early and adequate therapy. The aim of this review is to provide a tool for a rapid differential diagnosis among the various phenotypes of circulatory shock, based on the clinical, hemodynamic and biochemical profile. We also prompt to emphasize the role of multiparametric monitoring from the early phases of the management and the need to implement the time-dependent network to improve the outcome of these critical patients.

[The hypoxic patient in the intensive cardiac care unit: from nasal cannulas to oro-tracheal intubation]. / Il paziente ipossico in unità di terapia intensiva cardiologica: dalle cannule nasali all'intubazione oro-tracheale.

Acute respiratory failure is a frequent complication of patients admitted to the intensive cardiac care unit and it is associated with a poor short- and long-term outcome. Acute respiratory failure can be managed with traditional oxygen therapy, with high-flow nasal cannula, continuous positive airway pressure, non-invasive ventilation or invasive ventilation according to clinical and blood gas condition. The use of advanced respiratory therapies is associated with both respiratory and hemodynamic effects, therefore the intensivist cardiologist should know deeply these respiratory devices. The intensivist cardiologist should perform an early diagnosis of acute respiratory failure, an appropriate selection of the respiratory device, and accurate monitoring and management to obtain clinical improvement and to avoid mechanical invasive ventilation.

Heart transplantation and anti-HLA antibodY: myocardial dysfunction and prognosis - HeartLAy study.

AIMS: The presence of anti-human leucocyte antigen (HLA) antibodies has been implicated in a higher incidence of complications as well as mortality rate in heart transplantation. The aim of the study was to identify through non-invasive parameters early signs of myocardial dysfunction in the presence of anti-HLA antibodies but without evidence of antibody-mediated rejection (AMR) and its possible prognostic impact. METHODS AND RESULTS: A total of 113 heart-transplanted patients without acute cellular rejection (ACR) and AMR or cardiac allograft vasculopathy (CAV) were prospectively enrolled and divided into two groups ['HLA+' (50 patients) and 'HLA-' (63 patients)], based on the presence of anti-HLA antibodies. Each patient was followed for 2 years after the enrolment, recording episodes of AMR, ACR, CAV, and mortality. Clinical characteristics were similar between the two groups. Among laboratory data, N-terminal pro-B-type natriuretic peptide and high-sensitivity cardiac troponin values were significantly higher in the presence of anti-HLA antibodies (P < 0.001 and P = 0.003, respectively). The echocardiographic parameters that showed a statistically significant difference between the two groups were deceleration time of E wave (DecT E, P < 0.001), left ventricular global longitudinal strain (P < 0.001), tricuspid annular plane systolic excursion (P = 0.011), tricuspid S' wave (P = 0.002), and free wall right ventricular longitudinal strain (fwRVLS, P = 0.027), whereas left atrial strain did not differ significantly (P = 0.408). Univariate analysis showed that anti-HLA antibodies were associated with the development of CAV at both 1 and 2 year follow-up [odds ratio (OR) 11.90, 95% confidence interval (CI) 1.43-90.79, P = 0.022 and OR 3.37, 95% CI 1.78-9.67, P = 0.024, respectively]. Bivariate analysis demonstrated that both fwRVLS and DecT E were predictors of CAV development independently from HLA status. CONCLUSIONS: The presence of circulating anti-HLA antibodies is correlated with a mild cardiac dysfunction, even in the absence of AMR, and CAV development. Interestingly, reduced values of DecT E and fwRVLS were predictors of future development of CAV, independently from anti-HLA antibody.

[Practical approach to the patient with fever in the intensive cardiac care unit: diagnostic framework and therapy notes]. / Approccio pratico al paziente con febbre in terapia intensiva cardiologica: inquadramento diagnostico e cenni di terapia.

The management of the patient with fever in the intensive cardiac care unit begins with a thorough evaluation of the patient, particularly symptoms, clinical history and physical examination, to provide information regarding the origin of the fever. The global evaluation of the patient should be integrated with blood and microbiological tests, in particular blood culture and swab. The laboratory, microbiologic or radiologic tests could be more or less detailed and targeted depending on the type of suspected infection and clinical conditions of the patient. When therapy is necessary, it is crucial to switch, as soon as possible, from broad spectrum antibiotic therapy to antibiotic therapy based on the results of the microbiological exams. Antibiotic therapy could be associated with antipyretic and specific organ support therapy when necessary.

[Pulmonary hypertension clinical pathway: ANMCO Tuscany Board model]. / Clinical pathway per l'ipertensione polmonare: la proposta di ANMCO Toscana.

Pulmonary hypertension (PH) is defined by a mean pulmonary artery pressure >20 mmHg at rest during right heart catheterization. PH prevalence is about 1% of the global population. The PH clinical classification includes five groups: pulmonary arterial hypertension, PH associated with left heart disease, PH associated with lung disease, PH associated with pulmonary artery obstructions, PH with unclear and/or multifactorial mechanisms. In case of clinical suspicion, echocardiography is the first-line tool to start the diagnostic process. Right heart catheterization is the gold standard for diagnosis of PH, requires great experience and should be performed in expert centers. The classification of the PH patient in a specific subgroup requires multidisciplinary clinical and instrumental skills that only a reference center can provide. This document proposes a clinical pathway for the management of PH patients in the Tuscany region in order to standardize access to specialized care.

[Arrhythmias in adult congenital heart disease at the emergency department: ANMCO Tuscany clinical pathway]. / I clinical pathways dell'ANMCO Toscana: la gestione in urgenza delle aritmie nel cardiopatico congenito adulto.

Arrhythmias are a common complication in the adult population with congenital heart disease (ACHD). Arrhythmias often lead to hemodynamic instability and, on the other hand, may be a marker of hemodynamic impairment in ACHD patients, both in natural history and after cardiac surgery. Treatment requires knowledge of basic anatomy and any previous cardiac surgery; the availability of patient's health records, if possible, is therefore crucial for therapeutic choices. In the emergency setting, the first target is represented by the patient's hemodynamic stabilization; mainly in moderate or high complexity ACHD, the connection with the referral center is recommended, to which patients should be entrusted for follow-up. A regional epidemiological observatory, aiming to assess the number, type and outcomes of emergency admissions of ACHD patients could be a useful tool for analyzing the effectiveness of the collaboration network between the different structures involved and for implementing organizational pathways.

[Management of elderly patients in the cardiac intensive care unit: how to balance between appropriateness and futility]. / Gestione del paziente anziano in unità di terapia intensiva cardiologica: tra appropriatezza diagnostico-terapeutica e futilità.

The number of elderly patients admitted to cardiac intensive care units (CICU) is significantly increasing. Nowadays, novel diagnostic and therapeutic tools allow to treat the vast majority of cardiac acute diseases, nonetheless care of elderly patients requires a careful clinical evaluation. A favorable proportion of cost-effectiveness is warranted, aimed at avoiding futile procedures or treatments. On the other hand, the availability of minimally invasive procedures carries forward old limits to treatments in elderly patients in CICU. It appears evident that age cannot per se represent a limit in the care of elderly people. The present review gives insights in the management of the most common cardiovascular disease settings in elderly patients in the CICUs, thus providing important tools in complex decision-making.

[A clinical cardio-oncology pathway for the cardiology management of cancer outpatients: a joint proposal by ANMCO and AIOM Tuscany]. / Modello organizzativo e di un percorso clinico per la gestione cardiologica ambulatoriale del paziente oncologico: una proposta congiunta ANMCO e AIOM Toscana.

Cardio-oncology is now part of the standard clinical approach for patients with cancer and cannot be overlooked anymore. While its scientific background is solid and its clinical relevance is well known, its application in daily practice varies greatly among hospitals. To provide the best cardio-oncology care to cancer patients and to make cardio-oncology's clinical use uniform, we developed a shared multidisciplinary proposal for a dedicated clinical pathway. Our proposition presents the minimum requirements needed to which this path caters for, identifies patient categories to be entered into the path, highlights the role of a specific inter-hospital clinical and imaging network and indicates follow-up strategies during and after oncological treatments. The proposed pathway is based on some key elements and is easily adaptable to different hospitals with minimal changes.

[Clinical pathway for cardiogenic shock. A proposal from ANMCO Tuscany]. / Clinical pathway per lo shock cardiogeno. La proposta dell'ANMCO Toscana.

Cardiogenic shock is a clinical syndrome characterized by hypotension and hypoperfusion due to the inability of the heart to provide adequate cardiac output. It is an infrequent clinical condition still burdened by high mortality rates. In patients with cardiogenic shock rapid diagnosis, multiparameter monitoring and timely therapeutic strategies with pharmacological agents or mechanical circulatory support are necessary to provide adequate peripheral tissue perfusion and to improve outcome. Recent investigations reported lower mortality rates to be associated with clinical pathways based on a well-organized network, and on admission in high-volume specialized hospitals (Shock Center) with a dedicated multidisciplinary team (Shock Team). The aim of this clinical pathway for cardiogenic shock is to describe the best organization to ensure to Tuscan citizens an equal access to care independently of the site where they suffer from cardiogenic shock.

[Approach to the diagnosis and management of patients with cardiac amyloidosis. A consensus document by the Tuscan section of the Italian Association of Hospital Cardiologists (ANMCO) and the Tusco-Umbrian section of the Italian Society of Cardiology (SIC)]. / Percorso clinico-assistenziale in rete per la diagnosi e la gestione del paziente con amiloidosi cardiaca. Documento di consenso ANMCO Toscana e SIC Tosco-Umbra.

The diagnosis of cardiac amyloidosis (CA) is challenging because of its phenotypic heterogeneity, multi-organ involvement often requiring the interaction among experts in different specialties and subspecialties, the lack of a single non-invasive diagnostic tool, and limited awareness in the medical community. Recent studies have challenged the dogma of CA as a rare, incurable disease, and have redefined the epidemiology and therapeutic options for this condition. Missing or delaying the diagnosis may have a profound impact on patient outcome, as potentially life-saving treatments may be omitted or delayed, particularly chemotherapy in the case of amyloid light-chain amyloidosis. For a timely identification, clinical cardiologists should be able to recognize the "red flags" prompting a dedicated diagnostic work-up. Cardiologists could also face the challenge of making decisions about drug and device therapies for patients with known CA. The present consensus document aims to provide a practical guide and an organizational framework for professionals belonging to the Tuscan network of hospital cardiologists.

[ANMCO Position paper: Current evidence on intra-aortic balloon pump in advanced acute heart failure]. / Position paper ANMCO: Ruolo del contropulsatore aortico nel paziente con insufficienza cardiaca acuta avanzata.

The treatment of patients with advanced acute heart failure is still challenging. Intra-aortic balloon pump (IABP) has widely been used in the management of patients with cardiogenic shock. However, according to international guidelines, its routinary use in patients with cardiogenic shock is not recommended. This recommendation is derived from the results of the IABP-SHOCK II trial, which demonstrated that IABP does not reduce all-cause mortality in patients with acute myocardial infarction and cardiogenic shock. The present position paper, released by the Italian Association of Hospital Cardiologists (ANMCO), reviews the available data derived from clinical studies. It also provides practical recommendations for the optimal use of IABP in the treatment of cardiogenic shock and advanced acute heart failure. Data deriving from a national survey in Italian hospitals about IABP use are also provided.
