Deficiency of sarcoglycan-δ (Sgcd) induces disruption of the dystrophin glycoprotein complex, resulting in loss of membrane stability. We have reported that angiotensin II (AngII)-mediated autonomic dysfunction precedes and predicts development of dilated cardiomyopathy (DCM) in the global Sgcd-deficient mice [Exp Physiol 2015].The relative contribution of cardiomyocyte-targeted Sgcd on DCM and autonomic dysfunction remains unknown. Our goal is to determine whether cardiac remodeling in the Sgcd mutations is an intrinsic process of the cardiomyocytes...

AIM: We present the baseline characteristics of the PREFERS Stockholm epidemiological study on the natural history and course of new onset heart failure (HF) aiming to improve phenotyping focusing on HF with preserved left ventricular ejection fraction (HFpEF) pathophysiology. METHODS AND RESULTS: New onset HF patients diagnosed in hospital or at outpatient HF clinics were included at five Stockholm hospitals 2015-2018 and characterized by N-terminal pro brain natriuretic peptide (NT-proBNP), biomarkers, echocardiography, and cardiac magnetic resonance imaging (subset)...

BACKGROUND: The persistent changes in cardiac structure and function in children who survived twin-to-twin transfusion syndrome remain a matter of concern and controversy. Current fetal echocardiographic parameters and their postnatal evolution can help improve our understanding of the subject. OBJECTIVE: To describe the echocardiographic changes of monochorionic fetuses affected by twin-to-twin transfusion syndrome, the recipient and the donor, before and after laser photocoagulation and to determine their evolution in the third trimester and during their first year of life...

HYPOTHESIS/OBJECTIVES: To investigate signalment, clinical signs, diagnostic findings, and survival in dogs with HCM. ANIMALS: Sixty-eight client-owned dogs. METHODS: Retrospective multicenter study. Medical records were searched between 2003 and 2015. The diagnosis of left ventricular (LV) hypertrophy was made by echocardiographic examination...

BACKGROUND: Morbidity and mortality increase as Fontan patients age into adulthood. Limited studies have examined cardiac magnetic resonance and echocardiographic parameters to predict death and transplantation in children after the Fontan operation. The aim of this study was to investigate echocardiographic parameters in adolescents and adults after Fontan operation, including myocardial mechanics such as classic-pattern dyssynchrony (CPD), as predictors of transplantation or death. METHODS: In a cross-sectional retrospective study, strain analysis was performed on echocardiographic studies performed between 2001 and 2015 on 110 patients with single-ventricle physiology after the Fontan procedure...

BACKGROUND: Left ventricular diastolic dysfunction (LVDD) appears to be the earliest cardiac disturbance in cirrhosis patients. There are many previous reports reporting the significance of severity of LVDD on the outcome of liver transplantation or TIPS insertion, a few Indian studies have addressed the role of LVDD on survival in decompensated cirrhosis. The objective of this study is to assess the effect of LVDD on the survival of decompensated cirrhotic patients. METHODS: We prospectively evaluated 92 decompensated cirrhotic patients from April 2015 to March 2017 at IMS and SUM Hospital, Bhubaneswar, India...

Background: Atrial fibrillation of new onset during acute illness (AFNOAI) has a variable incidence of 1%-44% in hospitalized patients. This study assesses the risk factors for persistence of AFNOAI in the 5 years post hospital discharge for critically ill patients. Methods: This was a retrospective cohort study. All patients ≥18 years old admitted to the medical intensive care unit (MICU) of a tertiary care hospital from January 1st, 2012, to October 31st, 2015, were screened...

Left ventricular diastolic dysfunction (LVDD) can be affected by many factors, including epicardial adipose tissue (EAT), obesity and type-2 diabetes mellitus (T2DM). The aim of this study was to establish and validate an easy-to-use nomogram that predicts the severity of LVDD in patients with T2DM. This is a retrospective study of 84 consecutive subjects with T2DM admitted to the Endocrinology Department, the First People's Hospital of Zunyi City between January 2015 and October 2020. Several echocardiographic characteristics were used to diagnose diastolic dysfunction according to the 2016 diastolic dysfunction ASE guidelines...

AIM: To determine the diagnostic accuracy of pulmonary artery to aorta ratio in screening for pulmonary hypertension in advanced chronic obstructive pulmonary disease (COPD) patients. METHODS: A prospective, diagnostic study was conducted in University Hospital Center Zagreb between January 2015 and March 2018. The study enrolled 100 patients who consecutively underwent chest computed tomography (CT), echocardiographic exam, and right heart catheterization. Two independent observers measured pulmonary artery and ascending aorta diameters...

AIMS: Right ventricular (RV) allograft dysfunction is present in half of all heart transplant (HT) recipients. Non-invasive assessment of RV function in the setting of rejection is not well described. We outline an echocardiographic technique, short-axis fractional area change (SAXFAC), to evaluate RV function in the HT population and correlate this with the grade of pathologic rejection. METHODS AND RESULTS: We retrospectively reviewed the electronic medical records of 110 people who received a HT between 1 January 2015 and 29 February 2020 and had no evidence of rejection...

Importance: Serum uric acid (SUA) level is associated with vascular dysfunction in Eurasian populations, but little is known about this association in individuals from sub-Saharan Africa, who have a high prevalence of both relatively high SUA levels and vascular dysfunction. Objectives: To assess the associations of SUA levels with macrovascular and kidney microvascular dysfunction in individuals of sub-Saharan African ancestry and evaluate potential factors that could mediate these associations...

Background: With success and effective long-term antiretroviral treatment (ART), HIV-infected patients live longer and frequently developed non-communicable diseases (NCDs). Few studies have been conducted in low-income countries, particularly in West Africa. Methods: We carried out a cross-sectional study in the referral HIV centre of the Service des Maladies Infectieuses et Tropicales (SMIT) in Abidjan. From April to September 2015, we consecutively included HIV-1 infected patients aged 18 years and older, and on ART for a minimum of 12 months...

Transplant renal artery stenosis (TRAS) is the most common (1%-23%) vascular complication following kidney transplantation. The aim of this study was to review our experience with an endovascular approach to treat TRAS.We retrospectively reviewed kidney transplant recipients who underwent percutaneous transluminal angioplasty (PTA) due to TRAS in our institute from January 2009 to December 2015. We analyzed the patient's baseline characteristics, postoperative renal function, blood pressure evolution, and the number of pre- and post-procedure antihypertensive drugs...

BACKGROUND: End-diastolic opening of the pulmonary valve and subsequent antegrade diastolic pulmonary artery flow (ADPAF) reflect restrictive right ventricular (RV) physiology in children. However, this has attracted little attention in adults. PURPOSE: To clarify the clinical implications of ADPAF in adults. METHODS AND RESULTS: The study population consisted of 23,049 consecutive adult patients who underwent echocardiography in our hospital between 2008 and 2015...

Importance: Being born small for gestational age (SGA), approximately 10% of all births, is associated with increased risk of cardiovascular mortality in adulthood, but mechanistic pathways are unclear. Cardiac remodeling and dysfunction occur in fetuses SGA and children born SGA, but it is uncertain whether and how these changes persist into adulthood. Objective: To evaluate baseline cardiac function and structure and exercise capacity in young adults born SGA...

INTRODUCTION: In patients with right ventricular diastolic dysfunction after complete repair of tetralogy of Fallot, some employ the use of beta-blockade. The theoretical benefit of this therapy is felt to be one of the two: 1) reduction in heart rate with subsequent increase in diastolic filling time and stroke volume; 2) halting or reversal of right ventricular remodelling. This study aimed to characterise the use of beta-blockade in paediatric admissions with complete repair of tetralogy of Fallot and characterise the effects of beta-blockade on admission characteristics...

Cardiac rehabilitation (CR) improves symptoms and survival in patients with acute myocardial infarction (AMI). We studied the change of diastolic function and its prognostic impact after CR. After reviewing all consecutive AMI patients from January 2012 to October 2015, we analyzed 405 patients (mean, 63.7 ± 11.7 years; 300 males) with baseline and follow-up echocardiographic examinations. We divided them into three groups according to their CR sessions: No-CR group ( n = 225), insufficient-CR group (CR < 6 sessions, n = 117) and CR group (CR ≥ 6 sessions, n = 63)...

Introduction: Serum homocysteine (Hcy) level is associated with cardiocerebrovascular disease. However, the relationship between Hcy and hypertension-mediated organ damage (HMOD) in non-hospitalized residents has not been elucidated. We aimed to investigate the association of HMOD with Hcy in elderly Chinese. Methods: One thousand seven hundred and forty-four community-dwelling elderly Chinese (age ≥65 years) participated in the Northern Shanghai Study from Jun. 2014 to Aug. 2015. Hyperhomocysteinemia (HHcy) was defined as serum Hcy ≥15 mmol/L, and HMOD was estimated as arterial stiffness [carotid-femoral pulse wave velocity (CF-PWV) and ankle-brachial index (ABI)], cardiac impairment [left ventricular (LV) hypertrophy and LV diastolic dysfunction], and renal dysfunction [estimated glomerular filtration rate (eGFR) and urinary albumin/creatinine ratio]...

Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly associated with poor outcomes from high output cardiac failure and neurologic complications. Studies addressing fetal cardiovascular status and outcomes in this population are limited. A single-center retrospective review was conducted on patients with a prenatal diagnosis of VGAM who underwent a fetal echocardiogram between January 2015 and July 2019. Fetal echocardiographic data, brain magnetic resonance imaging (MRI) findings and outcomes were collected...
