A Cardiac Rehabilitation Program Increases the Acute Response of Endothelial Progenitor Cells to Maximal Exercise in Heart Failure Patients.

Purpose: The purpose of this study was to investigate the effect of a cardiac rehabilitation program on the acute response on endothelial progenitor cells and circulating endothelial cells after maximal exercise in patients with chronic heart failure of different severity.

Methods: Forty-four chronic heart failure patients were enrolled in a 36-session cardiac rehabilitation program. All patients underwent an initial maximal cardiopulmonary exercise test before and a final maximal cardiopulmonary exercise test after the cardiac rehabilitation program.

Practical Approaches to Build and Sustain a Cardio-Oncology Clinic.

The therapeutical advances in recent years in the field of oncology treatment have increased survival rates and improved the quality of life of oncology patients, thus turning cancer into a chronic disease. However, most of the new cancer treatments come at the expense of serious cardiovascular adverse events threatening the success story of these patients. The establishment of multidisciplinary medical teams to prevent, monitor, and treat cardiovascular diseases in cancer-treated patients is needed now more than ever.

Temporary Mechanical Circulatory Support in Cardiogenic Shock due to ST-Elevation Myocardial Infarction: Analysis of the National Readmissions Database.

Despite advances in temporary mechanical circulatory support (TMCS), in-hospital mortality and morbidity related to cardiogenic shock due to ST elevation myocardial infarction (CS-STEMI) are highly prevalent. We identified admissions with CS-STEMI between 2016 and 2019 from the National Readmission Database (NRD). Among 80 997 patients with CS-STEMI, we identified 42,139 without TMCS, while the remaining received various types of TMCS (Extra corporeal membrane oxygenation [ECMO] alone: n = 753; Intra-aortic balloon pump [IABP] alone: n = 27 556; Impella alone: n = 9055; ECMO with IABP or Impella: n = 1494).

Cardiotoxicity of Non-Anthracycline Cancer Chemotherapy Agents.

Throughout the last decades, newly developed chemotherapeutic agents and immunotherapies that target signaling pathways have provided patients with better prognoses, improved their quality of life and increased survival rates, thus converting cancer to a stable chronic disease. However, non-anthracycline cancer chemotherapy agents and immunotherapies including human epidermal growth factor receptor 2 (HER2) inhibitors, vascular endothelial growth factor (VEGF) inhibitors, Bcr-Abl tyrosine-kinase inhibitors (TKI), proteasome inhibitors, immune checkpoint inhibitors and chimeric antigen receptor T cells (CAR-T cells) may cause cardiovascular toxicity events and complications that usually interrupt the continuation of an appropriate treatment regimen, which induces life-threatening risks or leads to long-term morbidity. Heart failure, cardiac arrythmias and cardiomyopathies are the most common cardiovascular events related to cardiotoxicity due to chemotherapy.

Acute Cardiorespiratory Responses to Different Exercise Modalities in Chronic Heart Failure Patients-A Pilot Study.

The purpose of this study was to compare the acute cardiorespiratory responses and time spent above different %VO intensities between three "iso-work" protocols: (a) a high intensity interval training protocol (HIIT), (b) a higher intensity continuous protocol (CON) and (c) a lower intensity continuous protocol (CON) in patients with chronic heart failure (CHF). Ten male CHF patients (aged 55.1 ± 16.

Effects of exercise training on diastolic and systolic dysfunction in patients with chronic heart failure.

Background: Chronic heart failure (CHF) is a complex syndrome characterized by a progressive reduction of the left ventricular (LV) contractility, low exercise tolerance, and increased mortality and morbidity. Diastolic dysfunction (DD) of the LV, is a keystone in the pathophysiology of CHF and plays a major role in the progression of most cardiac diseases. Also, it is well estimated that exercise training induces several beneficial effects on patients with CHF.

Utilization and tolerance of beta-blockers among patients with AL amyloidosis.

Background: The utilization and clinical impact of beta-blockers (BBs) in cardiac amyloidosis (CA) is largely unexplored.

Methods: We conducted a retrospective, single-center analysis of indications, timing of initiation, types and doses of BB used, reasons to discontinue BB and association between BB tolerance and outcomes in a cohort of patients with immunoglobulin light chain amyloidosis (AL).

Results: We reviewed 236 patients with AL CA and identified 53 patients taking BB (22.

Angiotensin receptor-neprilysin inhibition in patients with acute decompensated heart failure: an expert consensus position paper.

The short-term mortality and rehospitalization rates after admission for acute heart failure (AHF) remain high, despite the high level of adherence to contemporary practice guidelines. Observational data from non-randomized studies in AHF strongly support the in-hospital administration of oral evidence-based modifying chronic heart failure (HF) medications (i.e.

The acute and long-term effects of a cardiac rehabilitation program on endothelial progenitor cells in chronic heart failure patients: Comparing two different exercise training protocols.

Background: Vascular endothelial dysfunction is an underlying pathophysiological feature of chronic heart failure (CHF). Endothelial progenitor cells (EPCs) are also impaired. The purpose of the study was to assess the effect of a cardiac rehabilitation (CR) program on the increase of EPCs at rest and on the acute response after maximal exercise in patients with CHF and investigate whether there were differences between two exercise training protocols and patients of NYHA II and III classes.

Next generation flow cytometry for MRD detection in patients with AL amyloidosis.

The treatment of AL amyloidosis aims to eradicate the plasma cell clone and eliminate toxic free light chain production. Only in a minority of patients the plasma cell clone is completely eradicated; residual light chain production may still exist while clonal relapse may occur. We used sensitive next-generation flow cytometry (NGF) to detect minimal residual disease (MRD) in AL amyloidosis patients at complete haematologic response.

Timing and impact of a deep response in the outcome of patients with systemic light chain (AL) amyloidosis.

A rapid and deep haematologic response is fundamental in order to improve outcomes of patients with AL amyloidosis. We evaluated the impact of timing and depth of haematologic response at early time points (at 1 and 3 months from the start of therapy) in 227 consecutive previously untreated AL patients, who received bortezomib-based primary therapy. After 1 month of therapy, 30.

Intracoronary Administration of Allogeneic Cardiosphere-Derived Cells Immediately Prior to Reperfusion in Pigs With Acute Myocardial Infarction Reduces Infarct Size and Attenuates Adverse Cardiac Remodeling.

Background: Allogeneic cardiosphere-derived cells (CDCs) exert cardioprotective effects when administered intracoronarily after reperfusion in animal models of acute myocardial infarction (AMI). The "no-reflow" phenomenon develops rapidly post-reperfusion and may undermine the efficacy of cell therapy, due to poor cell delivery in areas of microvascular obstruction (MVO). We hypothesized that CDC-induced cardioprotection would be enhanced by cell administration prior to reperfusion, when microvasculature is still relatively intact, to facilitate widespread cell delivery within the ischemic area.

Intravenous lipid emulsion as an antidote in clinical toxicology: a systematic review.

Objective: Intravenous lipid emulsions (ILE) were developed many decades ago to supply nutritional requirements to patients unable to obtain adequate enteral nutrition. The utility of ILE was extended to therapeutics, facilitating the delivery of drugs. More recently, the potential for ILE to act as an antidote for inversion of drug toxicity has been recognized.

Cardiac amyloidosis: in search of the ideal diagnostic tool.

Background: Cardiac amyloidosis (CA) is due to amyloid deposition in the myocardium. Transthyretin (ATTR) and light-chain (AL) amyloidosis are the main types of CA. Here, we present the clinical and imaging findings in patients with CA and discuss the controversies with the aim of finding the ideal diagnostic tool.

Primary treatment of light-chain amyloidosis with bortezomib, lenalidomide, and dexamethasone.

Bortezomib and dexamethasone with cyclophosphamide (CyBorD) or melphalan (BMDex) are commonly used primary treatments for light-chain (AL) amyloidosis, but limited data exist on bortezomib with immunomodulatory drug combinations. We report our experience with primary therapy with a bortezomib, lenalidomide, and dexamethasone (VRD) "light" regimen in 34 consecutive patients with AL amyloidosis. The majority (79%) had cardiac involvement, 15% and 23% were Mayo stage 3A and 3B, respectively, and 54% had renal involvement.

Efficacy of lenalidomide as salvage therapy for patients with AL amyloidosis.

We retrospectively evaluated 55 consecutive patients who received at least one dose of lenalidomide for relapsed/refractory AL amyloidosis. Their median age was 63 years; 72% had heart and 75% kidney involvement and 13% were on dialysis; while 20%, 46% and 34% had Mayo stage -1, -2 and -3 disease, respectively. Median time from start of primary therapy to lenalidomide was 15 months (range 2-100) and median number of prior therapies was 1 (range 1-4); 73% of the patients had prior bortezomib and 42% were bortezomib-refractory.

Cardio-oncology: A Focus on Cardiotoxicity.

Cardio-oncology is a recently developed field in cardiology aimed at significantly reducing cardiovascular morbidity and mortality and improving quality of life in cancer survivors. Cancer survival rates have been constantly increasing, mainly because of the advent of new, more potent and targeted therapies. However, many of the new therapies - along with some of the older chemotherapeutic regimens such as anthracyclines - are potentially cardiotoxic, which is reflected increasingly frequently in the published literature.

Coronary lesion progression as assessed by fractional flow reserve (FFR) and angiography.

Aims: The aim of this study was to explore the evolution of coronary lesions which had repeated physiologic evaluation by FFR as an endpoint, describe the clinical significance of longitudinal FFR change (ΔFFR=FFRfollow-up-FFRbaseline) and its correlation with angiographic indices, and identify predictors of FFRfollow-up.

Methods And Results: A retrospective, single-centre analysis of 414 stenoses (331 patients) with consecutive FFR measurements at least six months apart was performed (median time interval: 24 [17, 37] months). The change in percent diameter stenosis was 2% (-5%, 11%).

Cardiac and renal complications of carfilzomib in patients with multiple myeloma.

Clinical trials with carfilzomib have indicated a low but reproducible incidence of cardiovascular and renal toxicities. Among 60 consecutive myeloma patients treated with carfilzomib-based regimens who were thoroughly evaluated for cardiovascular risk factors, 12% (95% confidence interval, 3.8%-20%) experienced a reversible reduction of left ventricular ejection fraction (LVEF) by ≥20%, an objective measure of cardiac dysfunction.

Addition of cyclophosphamide and higher doses of dexamethasone do not improve outcomes of patients with AL amyloidosis treated with bortezomib.

Bortezomib, in combination with dexamethasone (VD) or with the addition of cyclophosphamide (VCD), is highly effective in patients with amyloid light-chain (AL) amyloidosis. Currently, VCD is considered as a primary regimen for patients with AL, but it is not clear whether the addition of cyclophosphamide to VD further and significantly improves efficacy, given the substantial activity of bortezomib itself. We retrospectively compared the outcomes of 101 patients with AL amyloidosis who received VD (n=59) or VCD (n=42) in two consecutive periods.

The role of levosimendan in acute heart failure complicating acute coronary syndrome: A review and expert consensus opinion.

Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease.
