Underdiagnosis of Fabry disease in minority ethnic groups.

Fabry disease (FD) is a rare, pan ethnic X-linked disorder. We explored ethnic representation in our service and a national patient organisation. An audit of the University Hospitals Birmingham FD cohort revealed that 9 % of index cases are minority ethnic, compared to 18.

Changes in peak oxygen consumption in Fabry disease and associations with cardiomyopathy severity.

Background: Fabry disease (FD) causes multiorgan sphingolipid accumulation, with cardiac involvement responsible for the largest burden of morbidity and mortality. Exercise intolerance in FD is prevalent, yet the mechanisms of this are poorly understood. The aim of this study was to assess exercise intolerance in FD and identify whether this correlates with the phase of cardiomyopathy.

Characterisation of infantile cardiomyopathy in Alström syndrome using ALMS1 knockout induced pluripotent stem cell derived cardiomyocyte model.

Alström syndrome (AS) is an inherited rare ciliopathy characterised by multi-organ dysfunction and premature cardiovascular disease. This may manifest as an infantile-onset dilated cardiomyopathy with significant associated mortality. An adult-onset restrictive cardiomyopathy may also feature later in life.

Defining the cardiovascular phenotype of adults with Alström syndrome.

Background: >40% of infants with Alström Syndrome (AS) present with a transient, severe cardiomyopathy in the first months of life, with apparent recovery in survivors. One in five individuals then develop a later-onset cardiomyopathy but wide clinical variability is observed, even within the same family. The rationale for this study is to provide a comprehensive evaluation of the cardiovascular phenotype in adults with AS.

Arrhythmogenesis in Fabry Disease.

Purpose Of Review: Fabry Disease (FD) is a rare lysosomal storage disorder characterised by multiorgan accumulation of glycosphingolipid due to deficiency in the enzyme α-galactosidase A. Cardiac sphingolipid accumulation triggers various types of arrhythmias, predominantly ventricular arrhythmia, bradyarrhythmia, and atrial fibrillation. Arrhythmia is likely the primary contributor to FD mortality with sudden cardiac death, the most frequent cardiac mode of death.

Clinical utilisation of implantable loop recorders in adults with Fabry disease-a multi-centre snapshot study.

Fabry disease (FD) is an X-linked deficiency of alpha-galactosidase-A, leading to lysosomal storage of sphingolipids in multiple organs. Myocardial accumulation contributes to arrhythmia and sudden death, the most common cause of FD mortality. Therefore, there is a need for risk stratification and prediction to target device therapy.

Phenoage and longitudinal changes on transthoracic echocardiography in Alström syndrome: a disease of accelerated ageing?

Alström syndrome (AS) is an ultra-rare disorder characterised by early-onset multi-organ dysfunction, such as insulin resistance, obesity, dyslipidaemia, and renal and cardiovascular disease. The objective is to explore whether AS is a disease of accelerated ageing and whether changes over time on echocardiography could reflect accelerated cardiac ageing. Cross-sectional measurement of Phenoage and retrospective analysis of serial echocardiography were performed between March 2012 and November 2022.

Changing trends in the incidence, management and outcomes of coronary artery perforation over an 11-year period: single-centre experience.

Introduction: Coronary artery perforation (CP) is a rare but life-threatening complication of percutaneous coronary intervention (PCI). This study aimed to assess the incidence, management and outcomes of CP over time.

Methods: A single-centre retrospective cohort study of all PCIs performed between January 2010 and December 2020.

Basic Research Approaches to Evaluate Cardiac Arrhythmia in Heart Failure and Beyond.

Patients with heart failure often develop cardiac arrhythmias. The mechanisms and interrelations linking heart failure and arrhythmias are not fully understood. Historically, research into arrhythmias has been performed on affected individuals or (animal) models.

Atherosclerosis in Fabry Disease-A Contemporary Review.

Fabry disease (FD) is a lysosomal storage disorder characterised by a deficiency in the enzyme α-galactosidase A resulting in sphingolipid deposition which causes progressive cardiac, renal, and cerebral manifestations. The case illustrates a patient with FD who died suddenly, and medical examination demonstrated myocardial scarring and prior infarction. Angina is a frequent symptom in FD.

Effects of Ivabradine on Hemodynamic and Functional Parameters in Left Ventricular Systolic Dysfunction: a Systematic Review and Meta-analysis.

Background: Ivabradine is licensed as add-on therapy in patients with severe left ventricular systolic dysfunction (LVSD), normal sinus rhythm, and suboptimal heart rate (HR) control, but effects are not fully established. This study sought to assess the impact of ivabradine therapy on hemodynamic and functional outcome measures in all patients with LVSD.

Methods: MEDLINE (1996-2017), Embase (1996-2017), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, ClinicalTrials.

A contemporary review of peripartum cardiomyopathy.

Peripartum cardiomyopathy reflects the presence of cardiac failure in the absence of determinable heart disease and occurs in late third trimester of pregnancy or up to 6 months postpartum. A full understanding of pathophysiological mechanisms is lacking, but excess prolactin levels, haemodynamic alterations, inflammation and nutritional deficiencies have all been implicated. Its clinical presentation has distinct overlap with physiological alterations in healthy pregnancy and this presents a diagnostic challenge.

Complicated bile duct stones.

Common bile duct stones (CBDSs) are solid deposits that can either form within the gallbladder or migrate to the common bile duct (CBD), or form de novo in the biliary tree. In the USA around 15% of the population have gallstones and of these, 3% present with symptoms annually. Because of this, there have been major advancements in the management of gallstones and related conditions.

Improving recording of capacity to consent and explanation of medication side effects in a psychiatric service for people with learning disability: audit findings.

This study aimed to examine the practice of psychiatrists in a large learning disability service in recording capacity to consent to treatment and side effect discussion, and the impact of measures aimed at improving this. Three audit cycles were completed between 2007 and 2009, each examining 26 case notes selected at random. Information was gathered on recording of capacity and documentation of explanation of potential side effects.
