Beta thalassemia is an autosomal, recessive disorder, characterized by ineffective erythropoiesis. Chronic transfusions and inability of body to eliminate iron lead to an iron overload, thereby causing damage to heart. Natriuretic peptides (NPs) are produced within the heart, which are then released into the circulation in response to ventricular wall stress. We, therefore, aimed to study the relation between ventricular dysfunction and N-terminal pro-B-type natriuretic peptides (NT-proBNPs). We enrolled 105 patients with increased serum ferritin levels and echocardiography was performed...

To investigate the inhibitory effect of Huangqi Danshen decoction (HDD) on isoproterenol (ISO)-induced myocardial remodeling and explore its effect on STIM1, TRPC1, CaN and NFATc3 expressions. ISO (2.5 mg•kg⁻¹•d⁻¹×14 d) was given by subcutaneous injection to establish myocardial remodeling models in rats, and then were randomly divided into control group, ISO model group, HDD5 group (HDD 5 g•kg⁻¹•d⁻¹+ISO), and HDD10 group (HDD 10 g•kg⁻¹•d⁻¹+ISO). After intervention for 4 weeks, the heart mass index (HW/BW) and the left ventricular mass index (LVW/BW) were calculated; the structure of myocardium was observed by echocardiography; the pathological changes of myocardium were observed by HE staining; levels of BNP, CaN and CaM kinases II in serum were detected by ELISA, and the protein expression levels of STIM1, TRPC1, p-CaN, p-NFATc3, and NFATc3 in left ventricular tissues were detected by Western blot...

Objective: To investigate the effect of cardiac stem cells (CSC) overexpressing integrin-linked kinase (ILK-CSC) transplantation on cardiac function after myocardial infarction (MI) and related mechanism. Methods: CSCs were isolated from the hearts of neonatal Sprague-Dawley (SD) rats and ILK-CSC were established by transfecting recombinant adenoviral vector harboring human wild-type ILK cDNA. Forty 8-week-old rats were randomly divided into 4 groups (n=10 each group): sham group, MI plus saline injection group(saline group), MI plus CSC transfected with null vector injection group (Ad-null-CSC group), and MI plus ILK-CSC injection group(ILK-CSC group)...

OBJECTIVES: The aim of this study was to assess feasibility and clinical effectiveness of the MitraClip device in octogenarians suffering from severe mitral valve regurgitation due to chordae rupture. BACKGROUND: The MitraClip procedure is a suitable technique in high-risk surgical patients to achieve safe and effective percutaneous repair of mitral valve regurgitation. Octogenarians show cumulative risk and social aspects hindering mitral valve surgery. No data exists regarding the use of the MitraClip device in high-risk octogenarians suffering from mitral valve chordae rupture...

BACKGROUND: Conventional echocardiographic technique for assessment of volume status and cardiac contractility utilizes left ventricular end-diastolic area (LVEDA) and fractional area of change (FAC), respectively. Our goal was to find a technically reliable yet faster technique to evaluate volume status and contractility by measuring left ventricular end-diastolic diameter (LVEDD) and fractional shortening (FS) in a cohort of mechanically ventilated trauma and burn patients using hemodynamic transesophageal echocardiographic (hTEE) monitoring...

No consensus view has been published on the relationship between the aldosterone synthase gene (CYP11B2) -344C/T polymorphism and left ventricular hypertrophy (LVH) in Chinese Han. We undertook a meta-analysis to investigate the potential association of this polymorphism and left ventricular structure-related phenotypes, including left ventricular mass (LVM), left ventricular mass index (LVMI), left ventricular end systolic diameter (LVESD), left ventricular end diastolic dimension (LVEDD), left ventricular posterior wall thickness (LVPWT), and interventricular septal wall thickness (IVS)...

BACKGROUND: Effects of cell therapy on dilated cardiomyopathy (DCM) have been investigated in pre-clinical models using distinct cellular types in each study. A single study that compares the effectiveness of different cells is lacking. METHODS: We have compared the effects of intramyocardial injection (IMI) of bone marrow (BM)-derived mononuclear cells (MNCs), BM and adipose tissue (AT) mesenchymal stromal cells (BM-MSCs and AT-MSCs) on heart function, histological changes and myocardial ultrastructure in a rat model of DCM...

The objective of this study is to examine the myocardial protective effect of antegrade cardioplegic cardiac arrest (ACC) versus ventricular fibrillation (VF) on short-term and mid-term left ventricular (LV) function in right ventricular outflow tract (RVOT) surgery. RVOT operations conducted from January 2006 to December 2015 were reviewed. The numbers of cases using ACC and VF were 71 and 49, respectively. Postoperative mortality and morbidity were compared between the two groups. Before and after propensity score matching, left ventricular ejection fraction (LVEF) and left ventricular end-systolic/end-diastolic diameter (LVESD/LVEDD) in echocardiography were measured immediately after operation and at mid-term follow-up between postoperative 6 and 24 months...

BACKGROUND: The NECTAR-HF study evaluated safety and feasibility of vagal nerve stimulation (VNS) for the treatment of heart failure patients. The first six-month randomized phase of the study did not show improvement in left ventricular remodelling in response to VNS. This study reports the 18-month results and provides novel findings aiming to understand the lack of efficacy of VNS, including a new technique assessing the effects of VNS. METHODS: Ninety-six patients were randomized 2:1 to active or inactive VNS for 6months, thereafter VNS was activated for all patients...
