Abstract Heart transplantation (HTx) is considered the “gold standard” therapy of refractory heart failure (HF), but it is accessible only to few patients because of the paucity of suitable heart ...donors. On the other hand, left ventricular assist devices (LVADs) have proven to be effective in improving survival and quality of life in patients with refractory HF. The challenge encountered by multidisciplinary teams in dealing with advanced HF lies in identifying patients who could benefit more from HTx as compared to LVAD implantation and the appropriate timing. The decision-making is based on clinical parameters, imaging-based data and risk scores. Current outcome of HF patients supported by LVAD (2-year survival around 70%) is rapidly improving and leads the way to a new therapeutic strategy. Patients who have a low likelihood to gain access to the heart graft pool could benefit more from LVAD implantation (defined as bridge to transplantation indication) than from remaining on HTx waiting list with the likely risk of clinical deterioration or removal from the list because patients are no longer suitable for transplantation. LVAD has also demonstrated to be effective in patients who are not considered eligible candidates for HTx with a destination therapy indication. HTx should be reserved to those patients for whom the maximum clinical benefit can be expected, such as young patients with no comorbidities. Here we discuss the current listing criteria for HTx and indications to implant of LVAD for patients with refractory acute and chronic HF based on the guidelines and the practical experience of our center.
Aims: This study aimed to compare the outcomes of the AUS and an adjustable male sling (ATOMSTM). Methods: It was a retrospective observational cohort study with two arms. Propensity score matching ...(PSM) was performed in order to limit selection bias and, consequently, a comparison between groups in terms of functional outcomes (24 h pad test and perception of improvement questionnaires), complications (overall complications, high-grade complications, reinterventions and explantations) and device survival was performed. Results: 49 patients in both arms were included. The baseline characteristics were similar between the groups. The mean follow up was 43 ± 35 months. Dryness was achieved in 22 patients (44.9%) in the AUS group and 11 (22.5%) in the sling group (p = 0.03). A total of 40 patients declared themselves well improved in the sling group (81%), while 35 (71%) declared the same in the AUS group (p = 0.78). The AUS was associated with more high-grade complications, reinterventions and explantations than the ATOMSTM. Survival at 60 months was 82 ± 9% in the sling group and 67 ± 7% in the AUS group (p = 0.03). Conclusions: While the AUS may be characterized by a higher dry rate, it has an increased risk of high-grade complications and reinterventions. It is proposed that the ATOMS prosthesis can be successfully used for patients who require a less invasive procedure that maintains good functional outcomes.
The field of inflammatory disease of the heart or "cardio-immunology" is rapidly evolving due to the wider use of non-invasive diagnostic tools able to detect and monitor myocardial inflammation. In ...acute myocarditis, recent data on the use of immunomodulating therapies have been reported both in the setting of systemic autoimmune disorders and in the setting of isolated forms, especially in patients with specific histology (e.g., eosinophilic myocarditis) or with an arrhythmicburden. A role for immunosuppressive therapies has been also shown in severe cases of coronavirus disease 2019 (COVID-19), a condition that can be associated with cardiac injury and acute myocarditis. Furthermore, ongoing clinical trials are assessing the role of high dosage methylprednisolone in the context of acute myocarditis complicated by heart failure or fulminant presentation or the role of anakinra to treat patients with acute myocarditis excluding patients with hemodynamically unstable conditions. In addition, the explosion of immune-mediated therapies in oncology has introduced new pathophysiological entities, such as immune-checkpoint inhibitor-associated myocarditis and new basic research models to understand the interaction between the cardiac and immune systems. Here we provide a broad overview of evolving areas in cardio-immunology. We summarize the use of new imaging tools in combination with endomyocardial biopsy and laboratory parameters such as high sensitivity troponin to monitor the response to immunomodulating therapies based on recent evidence and clinical experience. Concerning pericarditis, the normal composition of pericardial fluid has been recently elucidated, allowing to assess the actual presence of inflammation; indeed, normal pericardial fluid is rich in nucleated cells, protein, albumin, LDH, at levels consistent with inflammatory exudates in other biological fluids. Importantly, recent findings showed how innate immunity plays a pivotal role in the pathogenesis of recurrent pericarditis with raised C-reactive protein, with inflammasome and IL-1 overproduction as drivers for systemic inflammatory response. In the era of tailored medicine, anti-IL-1 agents such as anakinra and rilonacept have been demonstrated highly effective in patients with recurrent pericarditis associated with an inflammatory phenotype.
At the onset of ST-elevation acute myocardial infarction (STEMI), patients can present with very high circulating interleukin-6 (IL-6(+)) levels or very low-IL-6(-) levels.
We compared these 2 groups ...of patients to understand whether it is possible to define specific STEMI phenotypes associated with outcome based on the cytokine response.
We compared 109 patients with STEMI in the top IL-6 level (median, 15.6 pg/mL; IL-6(+) STEMI) with 96 in the bottom IL-6 level (median, 1.7 pg/mL; IL-6(-) STEMI) and 103 matched controls extracted from the multiethnic First Acute Myocardial Infarction study. We found minimal clinical differences between IL-6(+) STEMI and IL-6(-) STEMI. We assessed the inflammatory profiles of the 2 STEMI groups and the controls by measuring 18 cytokines in blood samples. We exploited clustering analysis algorithms to infer the functional modules of interacting cytokines. IL-6(+) STEMI patients were characterized by the activation of 2 modules of interacting signals comprising IL-10, IL-8, macrophage inflammatory protein-1α, and C-reactive protein, and monocyte chemoattractant protein-1, macrophage inflammatory protein-1β, and monokine induced by interferon-γ. IL-10 was increased both in IL-6(+) STEMI and IL-6(-) STEMI patients compared with controls. IL-6(+)IL-10(+) STEMI patients had an increased risk of systolic dysfunction at discharge and an increased risk of death at 6 months in comparison with IL-6(-)IL-10(+) STEMI patients. We combined IL-10 and monokine induced by interferon-γ (derived from the 2 identified cytokine modules) with IL-6 in a formula yielding a risk index that outperformed any single cytokine in the prediction of systolic dysfunction and death.
We have identified a characteristic circulating inflammatory cytokine pattern in STEMI patients, which is not related to the extent of myocardial damage. The simultaneous elevation of IL-6 and IL-10 levels distinguishes STEMI patients with worse clinical outcomes from other STEMI patients. These observations could have potential implications for risk-oriented patient stratification and immune-modulating therapies.
