Systemic inflammation as a novel QT-prolonging risk factor in patients with torsades de pointes
Conclusion The data are first to show that systemic inflammation via elevated IL-6 levels may represent a novel QT-prolonging risk factor contributing to TdP occurrence in the presence of other classical risk factors. If confirmed, this could open new avenues in antiarrhythmic therapy. (Source: Heart)

A current approach to heart failure in Duchenne muscular dystrophy
Duchenne muscular dystrophy (DMD) is a genetic, progressive neuromuscular condition that is marked by the long-term muscle deterioration with significant implications of pulmonary and cardiac dysfunction. As such, end-stage heart failure (HF) in DMD is increasingly becoming the main cause of death in this population. The early detection of cardiomyopathy is often challenging, due to a long subclinical phase of ventricular dysfunction and difficulties in assessment of cardiovascular symptomatology in these patients who usually loose ambulation during the early adolescence. However, an early diagnosis of cardiovascular disea...

Importance of the valve durability-life expectancy ratio in selection of a prosthetic aortic valve
Surgical aortic valve replacement (SAVR) has historically been the treatment of choice for patients with severe symptomatic aortic stenosis (AS). More recently, transcatheter aortic valve implantation (TAVI) has become a well-established alternative option for patients considered at high and intermediate preoperative surgical risk. TAVI provides effective relief of valve obstruction with excellent immediate and short-term outcomes. However, long-term (ie >10 years) durability of TAVI, relative to the known durability of surgical bioprosthetic valves,1 also needs to be considered. Indeed, there is, up to now, very f...

Genotype-phenotype correlations in Marfan syndrome
Marfan syndrome (MFS) is an autosomal dominant connective-tissue disorder associated with abnormalities of the cardiovascular, ocular and musculoskeletal systems. Aortopathy, manifest as thoracic aortic aneurysm (TAA) and dissection, is the major cause of morbidity and mortality. Most individuals with MFS carry mutations in the gene FBN1. This gene encodes the extracellular matrix (ECM) protein fibrillin-1, which plays essential roles in the formation of microfibrils, organisation of ECM components and sequestration of growth factors such as transforming growth factor beta (TGFβ). Thus, mutations in FBN1 lead to delet...

Heartbeat: The potential power of genotype-phenotype correlations
We now easily can do genetic testing for specific inherited conditions in our patients; indeed, sequencing of the whole genome is possible. Yet, even with inherited conditions due to changes in a single gene, such as the FBN1 gene in Marfan syndrome, there is considerable variation in the specific mutation in each patient. Presumably, resultant differences in the abnormal fibrillin-1 protein translate into differences in clinical disease manifestations. A better understanding of the genotype–phenotype relationships in Marfan syndrome might be useful in identifying which patients require more frequent diagnostic evalu...

Re: A case for palliative percutaneous coronary intervention

First, we agree that ‘palliative percutaneous coronary intervention (PCI)’ can be a very useful treatment in this elderly patient population. Locally at our institution, via our heart team meeting, we can offer an elderly symptomatic patient with multiple comorbidities PCI, which often fails to achieve complete revascularisation (even with small territories left ischaemic) but offers significant improvement in symptoms and can leave them safer in the presence of left main stem or proximal left ...

A case for palliative percutaneous coronary intervention
To the editor On reading the review on coronary revascularisation in the elderly by Cockburn et al,1 I must agree that more trials are needed to focus on the benefit of percutaneous coronary intervention (PCI) in elderly populations. When assessing these patients, clinicians should consider the impact of symptom relief versus procedural risk. If a patient is experiencing recurrent and debilitating chest pain requiring frequent hospital admission, then the risks of PCI, despite multiple comorbidities, could easily be rationalised when the benefit to the patient is clear. In such patients this ‘palliative PCI’ ap...

Catecholaminergic polymorphic tachycardia: underestimated and overtreated?
When the first four cases of catecholaminergic polymorphic tachycardia (CPVT) were reported over 40 years ago,1 we could only speculate about the incidence, cause and treatment of this elusive and lethal disease. Since then, important progress has been made in the understanding of CPVT, from bench to bedside. In 1999, Swan et al2 described a linkage to chromosome 1q42-q43, and 2 years later, the gene was identified as coding for the ryanodine receptor gene (RYR2).

Warfarin utilisation and anticoagulation control in patients with atrial fibrillation and chronic kidney disease
Conclusions There is a wide variation in anticoagulation prescription based on CKD severity. Patients with moderate-to-severe CKD, including dialysis, have substantially reduced TTR, despite comparable INR monitoring intensity. These findings have implications for more intensive warfarin management strategies in CKD or alternative therapies such as direct oral anticoagulants. (Source: Heart)

Amyloid heart disease: genetics translated into disease-modifying therapy
Given increased awareness and improved non-invasive diagnostic tools, cardiac amyloidosis has become an increasingly recognised aetiology of increased ventricular wall thickness and heart failure with preserved ejection fraction. Once considered a rare disease with no treatment options, translational research has harnessed novel pathways and led the way to promising treatment options. Gene variants that contribute to amyloid heart disease provide unique opportunities to explore potential disease-modifying therapeutic strategies. Amyloidosis has become the model disease through which gene therapy using small interfering RNA...

Drug-induced liver injury with oral anticoagulants: a threat or not?
Drug-induced liver injury (DILI) can develop with the use of virtually any drug. The growing list of medications or herbal products reported in association with DILI presently includes >1000 compounds, but the annual incidence of DILI has been estimated to only 1–1.5 per 1000–10 000 exposed persons.1 Nonetheless, DILI accounts for ~10% of all acute hepatitis cases and is the most common cause of acute liver failure (ALF).1 2 Drugs (or their metabolites) can affect the liver in a dose-dependent, predictable fashion (eg, acetaminophen) or via unpredictable immune-mediated (eg, phenytoin) or metabolic...

Oral anticoagulation in end-stage renal disease and atrial fibrillation: is it time to just say no to drugs?
Atrial fibrillation (AF) frequently complicates the management of chronic kidney disease, especially in patients with end-stage renal disease (ESRD). AF occurs in approximately one in five of the 650 000 patients with ESRD in the USA.1 ESRD confers increased risk for AF, while AF hastens progression to ESRD. The presence of chronic kidney disease in patients with AF is associated with an increased risk for ischaemic stroke independent of traditional risk factors. In addition, chronic kidney disease and particularly ESRD are associated with an increased risk of bleeding. Little is understood about how to safely reduce ...

Integrated programmes for cardiovascular disease risk reduction: the need for new models of care
Cardiovascular disease (CVD) remains a leading cause of mortality and morbidity worldwide. Although mortality rates for CVD have fallen by up to three-quarters in the UK, it still accounts for 26% of all deaths there. It costs the UK economy over £15 billion each year.1 Declining CVD mortality rates increases the number of individuals surviving into old age with CVD, leaving them at increased risk for a subsequent event. For individuals who have not suffered an event, the presence of certain genetic, behavioural and biological factors increases their risk of CVD. At least 80% of CVDs are potentially preventable by th...

Heartbeat: Managing cardiovascular disease as a family of diseases in the community
Although at least 80% of cardiovascular disease (CVD) is potentially preventable by the elimination of health risk behaviours, implementation of effective, large scale and sustainable CVD prevention programs is still a challenge. In this issue of Heart, Connolly et al1 describe an experience in which patients at high risk of or with established CVD underwent a 12 week community-based nurse-led prevention programme called My Action (figure 1) which included lifestyle and risk factor management, prescription of medication and weekly exercise and education sessions. The programme is in accordance to recent British recommendat...

The British Cardiovascular Society Annual Conference, Manchester, 5-7 June 2017: the Vice-Presidents message
One of the first questions I am asked whenever a forthcoming British Cardiovascular Society (BCS) Annual Conference is being discussed is the proposed ‘theme’ of the meeting. Initially I found this surprising as the main function of the conference, at least as far as the programme committee and I are concerned, is to provide a reasonably comprehensive coverage of the latest developments in all the subspecialist areas of cardiology rather than focus on a particular area. The concept of a theme arose a few years ago as a means of adding interest to the programme and as a stimulus for generation of ideas for novel...
