Cirrhotic cardiomyopathy: the liver affects the heart.

Braz J Med Biol Res 2019 Feb 14;52(2):e7809. Epub 2019 Feb 14.

Hospital Municipal Dr. Mario Gatti, Campinas, SP, Brasil.

Cirrhotic cardiomyopathy historically has been confused as alcoholic cardiomyopathy. The key points for diagnosis of cirrhotic cardiomyopathy have been well explained, however this entity was neglected for a long time. Nowadays the diagnosis of this entity has become important because it is a factor that contributes significantly to morbidity-mortality in cirrhotic patients. Read More

Hydrogen sulfide enhances the effectiveness of mesenchymal stem cell therapy in rats with heart failure: In vitro preconditioning versus in vivo co-delivery.

Biomed Pharmacother 2019 Feb 18;112:108584. Epub 2019 Feb 18.

Biochemistry Department, Faculty of Pharmacy, Cairo University, Cairo, Egypt. Electronic address:

Stem cell therapy represents a promising therapeutic avenue for cardiac disorders, including heart failure. Although stem cell transplantation showed encouraging preliminary results, the outcomes of clinical studies are still unsatisfactory. This study aimed to compare the outcomes of two therapeutic approaches, in vivo co-delivery of sodium hydrogen sulfide (NaHS) concomitant with bone marrow-derived mesenchymal stem cell (BMSC) transplantation and in vitro preconditioning of BMSCs with NaHS, both of which are intended to promote the success of stem cell therapy in rats with isoprenaline-induced heart failure.

Relation between invasive hemodynamics and measured glomerular filtration rate by Cr-EDTA clearance in advanced heart failure.

Scand J Clin Lab Invest 2019 Feb 20:1-8. Epub 2019 Feb 20.

a Department of Cardiology , Rigshopsitalet , Copenhagen , Denmark.

The interaction between hemodynamics and kidney function in heart failure (HF) is incompletely understood. We investigated the association between invasive hemodynamic parameters and measured glomerular filtration rate (mGFR) by plasma clearance of 51-chromium-labeled ethylenediamine tetra-acetic acid (Cr-EDTA) in patients with advanced HF and tested the hypothesis that patients with reduced mGFR have lower cardiac index (CI) and mean arterial pressure (MAP) as well as higher central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP). We retrospectively studied 242 patients (mean age 50 ± 13 years) referred for evaluation for heart transplantation or implantation of a left ventricular assist device with a left ventricular ejection fraction < 45% on optimal medical therapy, who underwent right heart catheterization (RHC) and measurement of Cr-EDTA clearance.

Lung diffusion capacity in advanced heart failure: relation to central haemodynamics and outcome.

ESC Heart Fail 2019 Feb 19. Epub 2019 Feb 19.

Department of Cardiology, Rigshospitalet, 2142, 9 Blegdamsvej, DK-2100, Copenhagen, Denmark.

Aims: Patients with heart failure (HF) are known to have a reduced pulmonary diffusion capacity for carbon monoxide (D ), but little is known about how lung function relates to central haemodynamics. The aim of this study was to investigate the association between haemodynamic variables and pulmonary diffusion capacity adjusted for alveolar volume in congestive HF patients and to analyse how predicted D /V affects mortality in relation to the haemodynamic status.

Methods And Results: We retrospectively studied right heart catheterization (RHC) and lung function data on 262 HF patients (mean age 51 ± 13 years) with a left ventricular ejection fraction < 45% referred non-urgently for evaluation for heart transplantation (HTX) or left ventricular assist device (LVAD).

Cardiac Assist Devices: Early Concepts, Current Technologies, and Future Innovations.

Bioengineering (Basel) 2019 Feb 15;6(1). Epub 2019 Feb 15.

Department of Biomedical Engineering, Carnegie Mellon University, Pittsburgh, PA 15213, USA.

Congestive heart failure (CHF) is a debilitating condition that afflicts tens of millions of people worldwide and is responsible for more deaths each year than all cancers combined. Because donor hearts for transplantation are in short supply, a safe and durable means of mechanical circulatory support could extend the lives and reduce the suffering of millions. But while the profusion of blood pumps available to clinicians in 2019 tend to work extremely well in the short term (hours to weeks/months), every long-term cardiac assist device on the market today is limited by the same two problems: infections caused by percutaneous drivelines and thrombotic events associated with the use of blood-contacting surfaces.

Eileen M Hsich

Circulation 2019 Feb;139(8):1080-1093

Heart and Vascular Institute at the Cleveland Clinic, OH. Cleveland Clinic Lerner College of Medicine of Case Western Reserve University School of Medicine, OH.

This in-depth review of sex differences in advanced heart failure therapy summarizes the existing literature on implantable cardioverter defibrillators, biventricular pacemakers, mechanical circulatory support, and transplantation with a focus on utilization, efficacy/clinical effectiveness, adverse events, and controversies. One will learn about the controversies regarding efficacy/clinical effectiveness of implantable cardioverter defibrillators and understand why these devices should be implanted in women even if there are sex differences in appropriate shocks. Individuals will learn about the sex differences with biventricular pacemakers with respect to ventricular remodeling and reduction in heart failure hospitalizations/mortality, as well as, possible mechanisms.

Hypoimmunogenic derivatives of induced pluripotent stem cells evade immune rejection in fully immunocompetent allogeneic recipients.

Nat Biotechnol 2019 Feb 18. Epub 2019 Feb 18.

Department of Surgery, Division of Cardiothoracic Surgery, Transplant and Stem Cell Immunobiology-Lab, University of California San Francisco, San Francisco, CA, USA.

Autologous induced pluripotent stem cells (iPSCs) constitute an unlimited cell source for patient-specific cell-based organ repair strategies. However, their generation and subsequent differentiation into specific cells or tissues entail cell line-specific manufacturing challenges and form a lengthy process that precludes acute treatment modalities. These shortcomings could be overcome by using prefabricated allogeneic cell or tissue products, but the vigorous immune response against histo-incompatible cells has prevented the successful implementation of this approach.

Effect of High-Intensity Interval Training in De Novo Heart Transplant Recipients in Scandinavia: 1-Year Follow-Up of the HITTS Randomized, Controlled Study.

Circulation 2019 Feb 18. Epub 2019 Feb 18.

Department of Cardiology, Oslo University Hospital, Rikshospitalet, Oslo, Norway.

Background: There is no consensus on how, when, or at what intensity exercise should be performed after heart transplantation (HTx). We have recently shown that high-intensity interval training (HIT) is safe, well tolerated, and efficacious in the maintenance state after HTx, but studies have not investigated HIT effects in the de novo HTx state. We hypothesized that HIT could be introduced early after a HTx, and that it could lead to clinically meaningful increases in exercise capacity and health-related quality of life (HRQoL). Read More

Translational research in pulmonary fibrosis.

Transl Res 2019 Feb 5. Epub 2019 Feb 5.

Department of Medicine, University of Colorado School of Medicine, Aurora, Colorado.

Pulmonary fibrosis refers to the development of diffuse parenchymal abnormalities in the lung that cause dyspnea, cough, hypoxemia, and impair gas exchange, ultimately leading to respiratory failure. Though pulmonary fibrosis can be caused by a variety of underlying etiologies, ranging from genetic defects to autoimmune diseases to environmental exposures, once fibrosis develops it is irreversible and most often progressive, such that fibrosis of the lung is one of the leading indications for lung transplantation. This review aims to provide a concise summary of the recent advances in our understanding of the genetics and genomics of pulmonary fibrosis, idiopathic pulmonary fibrosis in particular, and how these recent discoveries may be changing the clinical approach to diagnosing and treating patients with fibrotic interstitial lung disease.

J Am Coll Cardiol 2019 Feb;73(6):698-716

Division of Cardiology, Icahn School of Medicine at Mount Sinai, New York, New York.

Venoarterial extracorporeal membrane oxygenation (ECMO) is a rescue therapy that can stabilize patients with hemodynamic compromise, with or without respiratory failure, for days or weeks. In cardiology, the main indications for ECMO include cardiac arrest, cardiogenic shock, post-cardiotomy shock, refractory ventricular tachycardia, and acute management of complications of invasive procedures. The fundamental premise underlying ECMO is that it is a bridge-to recovery, to a more durable bridge, to definitive treatment, or to decision. Read More

Treatment with mononuclear cell populations improves post-infarction cardiac function but does not reduce arrhythmia susceptibility.

PLoS One 2019 14;14(2):e0208301. Epub 2019 Feb 14.

Department of Cardiology, University of Bonn, Bonn, Germany.

Background: Clinical and experimental data give evidence that transplantation of stem and progenitor cells in myocardial infarction could be beneficial, although the underlying mechanism has remained elusive. Ventricular tachyarrhythmia is the most frequent and potentially lethal complication of myocardial infarction, but the impact of mono nuclear cells on the incidence of ventricular arrhythmia is still not clear.

Objective: We aimed to characterize the influence of splenic mononuclear cell populations on ventricular arrhythmia after myocardial infarction. Read More

Evaluation of myocardial dispersion of repolarization in patients with heart transplantation

Turk J Med Sci 2019 Feb 11;49(1):212-216. Epub 2019 Feb 11.

Background/aim: The number of patients with heart transplantation has dramatically increased in the last decade. Considerable studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. We analyzed the dispersion of myocardial repolarization using electrocardiographic Tp-e interval and Tp-e/QTc ratio in patients with heart transplantation. Read More

Circulating mitochondria in organ donors promote allograft rejection.

Am J Transplant 2019 Feb 14. Epub 2019 Feb 14.

Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, California.

The innate immune system is a critical regulator of the adaptive immune responses that lead to allograft rejection. It is increasingly recognized that endogenous molecules released from tissue injury and cell death are potent activators of innate immunity. Mitochondria, ancestrally related to bacteria, possess an array of endogenous innate immune activating molecules. Read More

Butyrate Attenuates Lung Inflammation by Negatively Modulating Th9 Cells.

Front Immunol 2019 29;10:67. Epub 2019 Jan 29.

Laboratory of Transplantation Immunobiology, Department of Immunology, Institute of Biomedical Sciences, University of São Paulo, São Paulo, Brazil.

Th9 cells orchestrate allergic lung inflammation by promoting recruitment and activation of eosinophils and mast cells, and by stimulating epithelial mucus production, which is known to be mainly dependent on IL-9. These cells share developmental pathways with induced regulatory T cells that may determine the generation of one over the other subset. In fact, the FOXP3 transcription factor has been shown to bind locus and repress IL-9 production. Read More

Multidrug-Resistant Accelerate Intestinal, Extra-Intestinal, and Systemic Inflammatory Responses in Human Microbiota-Associated Mice With Subacute Ileitis.

Front Immunol 2019 29;10:49. Epub 2019 Jan 29.

Gastrointestinal Microbiology Research Group, Institute of Microbiology, Infectious Diseases and Immunology, Berlin Institute of Health, Charité - University Medicine Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, Berlin, Germany.

The globally rising incidences of multidrug-resistant (MDR) (Psae) in humans and live-stock animals has prompted the World Health Organization to rate MDR Psae as serious threat for human health. Only little is known, however, regarding factors facilitating gastrointestinal Psae-acquisition by the vertebrate host and subsequently induced inflammatory sequelae. In the present study, we addressed whether subacute ileitis predisposed mice harboring a human gut microbiota for intestinal MDR Psae carriage and whether inflammatory responses might be induced following peroral challenge with the opportunistic pathogen.

Tumorigenicity assay essential for facilitating safety studies of hiPSC-derived cardiomyocytes for clinical application.

Sci Rep 2019 Feb 13;9(1):1881. Epub 2019 Feb 13.

Department of Cardiovascular Surgery, Osaka University Graduate School of Medicine, Suita, Osaka, 565-0871, Japan.

Transplantation of cardiomyocytes (CMs) derived from human induced pluripotent stem cells (hiPSC-CMs) is a promising treatment for heart failure, but residual undifferentiated hiPSCs and malignant transformed cells may lead to tumor formation. Here we describe a highly sensitive tumorigenicity assay for the detection of these cells in hiPSC-CMs. The soft agar colony formation assay and cell growth analysis were unable to detect malignantly transformed cells in hiPSC-CMs. Read More

Pluripotent stem cell-derived myogenic progenitors remodel their molecular signature upon in vivo engraftment.

Proc Natl Acad Sci U S A 2019 Feb 13. Epub 2019 Feb 13.

Lillehei Heart Institute, Department of Medicine, University of Minnesota, Minneapolis, MN 55455;

Optimal cell-based therapies for the treatment of muscle degenerative disorders should not only regenerate fibers but provide a quiescent satellite cell pool ensuring long-term maintenance and regeneration. Conditional expression of Pax3/Pax7 in differentiating pluripotent stem cells (PSCs) allows the generation of myogenic progenitors endowed with enhanced regenerative capacity. To identify the molecular determinants underlying their regenerative potential, we performed transcriptome analyses of these cells along with primary myogenic cells from several developmental stages.

What the Cardiologist Should Know About Mitochondrial Cardiomyopathy?

Can J Cardiol 2019 Feb 29;35(2):221-224. Epub 2018 Nov 29.

Department of Cardiology, Institut universitaire de cardiologie et de pneumologie de Québec, Laval University, Quebec City, Quebec, Canada. Electronic address:

Mitochondrial diseases are a heterogeneous group of rare hereditary disorders that may manifest with single organ involvement or as multisystemic disease. The pathophysiology of mitochondrial disease is complex and related to mutations of genes encoding mitochondrial proteins that are crucial to the cellular respiratory chain. Given its almost exclusive aerobic metabolism, the heart is particularly susceptible to mitochondrial dysfunction and commonly involved in mitochondrial disorders. Read More

Temporal Patterns of 14 Blood Biomarker candidates of Cardiac Remodeling in Relation to Prognosis of Patients With Chronic Heart Failure-The Bio- SH i FT Study.

J Am Heart Assoc 2019 Feb;8(4):e009555

1 Department of Cardiology Erasmus MC Rotterdam the Netherlands.

Background Remodeling biomarkers carry high potential for predicting adverse events in chronic heart failure ( CHF ) patients. However, temporal patterns during the course of CHF , and especially the trajectory before an adverse event, are unknown. We studied the prognostic value of temporal patterns of 14 cardiac remodeling biomarker candidates in stable patients with CHF from the Bio-SHiFT (Serial Biomarker Measurements and New Echocardiographic Techniques in Chronic Heart Failure Patients Result in Tailored Prediction of Prognosis) study.

Stem Cell and Left Ventricular Assist Device Combination Therapy.

Circ Heart Fail 2019 Feb;12(2):e005454

Advanced Heart Failure and Transplantation Center, University Medical Center Ljubljana, Slovenia (G.P., B.V.).

Ventricular assist device (VAD) technology has evolved significantly over the past decades and currently represents one of the most important treatment strategies for patients with advanced chronic heart failure. There is increasing evidence that in selected patients undergoing long-term VAD support, improvement of myocardial structure and function may occur. However, there seems to be a significant discrepancy between structural and functional recovery of the failing myocardium, as only a small fraction of VAD-supported patients demonstrate reverse structural remodeling and eventually reach clinically significant and stable, functional improvement.
