The Journal of Heart and Lung Transplantation: 50 years of heart transplantation progress

(Elsevier) This month marks the 50th anniversary of the world's first human heart transplant performed at Groote Schuur Hospital in Cape Town by South African surgeon, Christiaan Barnard. He transplanted the heart of a 25-year-old woman into Louis Washkansky, a 53-year-old diabetes patient who was in severe heart failure. A special issue of The Journal of Heart and Lung Transplantation presents a chronicle of the major milestones in heart transplantation over the last 50 years.

Patients with type 2 diabetes mellitus (DM) and systolic heart failure (HF) often show improved glycemic control and reduced diabetes medication requirements after left ventricular assist device (LVAD) implantation. However, LVAD recipients also show increased body mass index (BMI) over time. We sought to determine whether post-LVAD improvements in hemoglobin A1c (HbA1c) are affected by changes in BMI.

Hemoglobin A1c, a common metric of glycemic control in diabetics, has been associated with various outcomes in the ambulatory heart failure population. Currently, only end organ damage secondary to diabetes is a contraindication to heart transplant (HT) and no optimal A1c prior to HT has been identified.

In conclusion, senescence of vascular cells promotes the development of age-related disorders, including heart failure, diabetes, and atherosclerotic diseases, while suppression of vascular cell senescence ameliorates phenotypic features of aging in various models. Recent findings have indicated that specific depletion of senescent cells reverses age-related changes. Although the biological networks contributing to maintenance of homeostasis are extremely complex, it seems reasonable to explore senolytic agents that can act on specific cellular components or tissues. Several clinical trials of senolytic agents are currentl...

AbstractPurposeEnd-stage renal disease (ESRD) is associated with increased cardiovascular risk factors, electrolyte imbalances, and iron deficiency anemia. These factors may increase the risk of adverse outcomes in patients undergoing panniculectomy. There is a paucity of data regarding outcomes in patients with ESRD undergoing panniculectomy. The purpose of this study is to investigate whether ESRD is associated with increased rate of complications following a panniculectomy.MethodThe Nationwide Inpatient Sample database (2006 –2011) was used to identify patients who underwent a panniculectomy. Among this cohort, pa...

In this study, we integrated atomic force microscopy (AFM) and molecular approaches to determine whether increased stiffness of aortic VSMCs in hypertensive rats is ROCK-dependent, and whether the anti-hypertensive effect of ROCK inhibitors contributes to the reduction of aortic stiffness via changing VSMC mechanical properties. Despite a widely held belief that aortic stiffening is associated with changes in extracellular matrix proteins and endothelial dysfunction, our recent studies demonstrated that intrinsic stiffening of aortic VSMCs, independent of VSMC proliferation and migration, is an important contributo...

Conclusions: Alterations to RV structure may represent a mechanism by which long-term PM10–2.5 exposure increases risks for adverse respiratory and cardiovascular outcomes, especially among certain susceptible populations. https://doi.org/10.1289/EHP658 Received: 14 June 2016 Revised: 24 February 2017 Accepted: 16 March 2017 Published: 27 July 2017 Address correspondence to S.

This study aimed to estimate associations between combined measurements of BMI and waist-to-hip ratio (WHR) with mortality and incident coronary artery disease (CAD). This study followed 130,473 UK Biobank participants aged 60-69 years (baseline 2006-2010) for 8.3 years (n = 2974 deaths). Current smokers and individuals with recent or disease-associated (e.g., from dementia, heart failure, or cancer) weight loss were excluded, yielding a "healthier agers" group. Ignoring WHR, the risk of mortality for overweight subjects was similar to that for normal-weight subjects. However, among normal-weight subjects...

In conclusion, the analyses do not permit us to predict the trajectory that maximum lifespans will follow in the future, and hence provide no support for their central claim that the maximum lifespan of humans is "fixed and subject to natural constraints". This is largely a product of the limited data available for analysis, owing to the challenges inherent in collecting and verifying the lifespans of extremely long-lived individuals. A reply from Jan Vijg's research group The authors of the accompanying comment disagree with our finding of a limit to human lifespan. Although we thank them for a...

In this study, we focused on two pathways of cardiomyocytes or heart cells: the Hippo pathway, which is involved in stopping renewal of adult cardiomyocytes, and the dystrophin glycoprotein complex (DGC) pathway, essential for cardiomyocyte normal functions." Previous work had hinted that components of the DGC pathway may somehow interact with members of the Hippo pathway. The researchers genetically engineered mice to lack genes involved in one or both pathways, and then determined the ability of the heart to repair an injury. These studies showed for the first time that dystroglycan 1, a component of the DGC ...
