Ghrelin and synthetic growth hormone secretagogues have diverse effects on the hypothalamus including effects on appetite and the growth hormone axis as well as on the hypothalamus-pituitary-adrenal (HPA) axis. We previously studied the effect of synthetic growth hormone secretagogues on CRH and AVP release from rat hypothalami in vitro, and now report on(More)
OBJECTIVES Ghrelin is a brain-gut peptide with GH-releasing and appetite-inducing activities and a widespread tissue distribution. Ghrelin is the endogenous ligand of the GH secretagogue receptor type 1a (GHS-R1a), and both ghrelin and the GHS-R1a are expressed in the pituitary. There are conflicting data regarding the effects of ghrelin on cell(More)
BACKGROUND Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Despite the advances in medical and catheter-based therapy for acute myocardial infarction the 1-year mortality remains as high as 13% and the 5-year prognosis for patients with heart failure remains as high as 50%. Left ventricular systolic dysfunction, a major(More)
BACKGROUND Bone marrow stem cell (BMSC) therapy for cardiovascular disease has shown considerable preclinical and clinical promise, but there remains a need for mechanistic studies to help bridge the transition from bench to bedside. We have designed a substudy to our REGENERATE-IHD trial (ClinicalTrial.gov Identifier: NCT00747708) to assess the feasibility(More)
Stem cell transplantation is emerging as a potential therapy to treat heart diseases. Promising results from early animal studies led to an explosion of small, non-controlled clinical trials that created even further excitement by showing that stem cell transplantation improved left ventricular systolic function and enhanced remodelling. However, the(More)
BACKGROUND Administrative data have been used to construct risk-adjustment models for provider profiling to benchmark hospital performance for acute myocardial infarction (AMI), but much less for acute coronary syndrome (ACS). We assess the impact on risk model performance and hospital-level mortality rate ratios (SMRs) of three key issues: comorbidity(More)
The hybrid approach to percutaneous treatment of chronic total occlusion (CTO) of coronary arteries requires both antegrade and retrograde skillsets. In the retrograde approach, wire externalization through the antegrade guide catheter often requires the use of a short donor guide catheter and a long (>150 cm) micro-catheter. Despite this there are(More)
AIM This study presents an interim safety and feasibility analysis of the REGENERATE-IHD randomized controlled trial, which is examining the safety and efficacy of three different delivery routes of bone marrow-derived stem cells (BMSCs) in patients with ischemic heart failure. METHODS & RESULTS The first 58 patients recruited to the REGENERATE-IHD study(More)
AIM Tβ4 is an integral factor in repair of myocardium in animal models. To investigate whether Tβ4 is important in human cardiac disease and has a role in mediating the beneficial cardiac effects of bone-marrow-derived stem cell (BMSC) therapy, we measured serial plasma Tβ4 levels in patients enrolled on the REGENERATE-IHD cell therapy trial. PATIENTS &(More)
The potential of autologous bone marrow (BM)-derived progenitor/stem cell (BMSC) therapy for cardiac repair maybe limited by patient-related factors, such as age and the disease process itself. In this exploratory analysis, we assessed the impact of age, different disease states, and granulocyte colony-stimulating factor (G-CSF) therapy on progenitor cell(More)
