Recommendations for driving after implantable cardioverter defibrillator implantation and the use of a wearable cardioverter defibrillator : Different viewpoints around the world.

The use of implantable cardioverter defibrillators (ICD) has been shown to improve survival in patients at risk of sudden cardiac death; however, due to the continuous risk of sudden loss of consciousness during arrhythmia or ICD intervention, they pose a potential risk to other road users while driving. A large number of opinions and recommendations from authorities and medical societies all over the world exist regarding driving restrictions after ICD implantation. This analysis provides an overview of the recommendations on driving restrictions from several countries.

Lipoprotein apheresis in Austria - Reduction of cardiovascular events by regular lipoprotein apheresis treatment.

Background: In Austria, about 12 patients per 1 million inhabitants are treated currently with lipoprotein (LP-) apheresis. In 2016 it has been suggested, that about 5000 patients were treated worldwide with LP-apheresis, more than half of them in Germany. Regular LP-apheresis aims to decrease apolipoprotein B-rich lipoproteins and to reduce cardiovascular events.

One year follow-up of patients with reduced left ventricular ejection fraction (LVEF) on lipoprotein apheresis.

Background: Left ventricular ejection fraction (LVEF) is a valuable measure to assess left ventricular systolic function. Lipid lowering therapy by statins has been shown to have an impact on LVEF already after a 6 months treatment. Higher doses of statins have been claimed to be more effective as compared to a conventional one and even a difference between lipophilic and hydrophilic compounds has been reported.

Lipoprotein apheresis - Shortening of treatment intervals reduces cardiovascular events: Case reports.

Background: Lipoprotein (Lp-) apheresis is a life-long therapy, usually performed in weekly intervals. In some cases, however, atherosclerotic disease progresses despite adequate therapy with weekly Lp-apheresis and maximal lipid lowering medication. In an attempt to improve the effectiveness of therapy, we temporarily shortened treatment intervals of Lp-apheresis in patients with elevated lipoprotein(a) (Lp(a)) and further progression of coronary atherosclerosis despite weekly Lp-apheresis and maximal lipid lowering medication.

Statin-induced muscular side effects at rest and exercise - An anatomical mapping.

Background And Aims: Muscle-related symptoms with or without creatine kinase (CK) elevation are common adverse effects associated with statin use. Symptoms are ranging from benign myalgia to myositis and in rare cases to rhabdomyolysis. The aim was to characterize and describe muscular side effects and create an anatomical frequency mapping.

Alirocumab as add-on therapy to statins: current evidence and clinical potential.

Atherosclerotic cardiovascular diseases (ASCVDs) are associated with a substantial mortality, physical morbidity, and mental disability. Elevated plasma low-density lipoprotein cholesterol (LDL-C) levels play a major role in the pathophysiology of ASCVDs. Statins have been shown to reduce ASCVD risk and associated events and are recommended as first-line therapy for treatment of hypercholesterolemia by current international guidelines.

DNA methylation, through DNMT1, has an essential role in the development of gastrointestinal smooth muscle cells and disease.

DNA methylation is a key epigenetic modification that can regulate gene expression. Genomic DNA hypomethylation is commonly found in many gastrointestinal (GI) diseases. Dysregulated gene expression in GI smooth muscle cells (GI-SMCs) can lead to motility disorders.

Acute Severe Mitral Stenosis Immediately After Transcatheter Aortic Valve Implantation.

An 86-year-old female patient was referred for treatment of symptomatic severe aortic stenosis. The heart team decided to perform transfemoral transcatheter aortic valve implantation. A 25 mm transcatheter aortic valve was implanted, but the valve migrated low into the left ventricular outflow tract.

[Therapeutic options in hyperlipidemia].

Treatment of lipid disorders (dyslipidemia) is the cornerstone of atherosclerosis prevention and reduction of progression. Lifestyle modification is the first step to improve the plasma lipid profile. Statins play a central role in the reduction of LDL cholesterol.

Serum response factor regulates smooth muscle contractility via myotonic dystrophy protein kinases and L-type calcium channels.

Serum response factor (SRF) transcriptionally regulates expression of contractile genes in smooth muscle cells (SMC). Lack or decrease of SRF is directly linked to a phenotypic change of SMC, leading to hypomotility of smooth muscle in the gastrointestinal (GI) tract. However, the molecular mechanism behind SRF-induced hypomotility in GI smooth muscle is largely unknown.

Molecular imaging of atherosclerotic lesions by positron emission tomography - can it meet the expectations?

Early non-invasive imaging of atherosclerosis and in particular the detection of lesions at risk with high specificity could significantly affect cardiovascular morbidity and mortality. Conventional nuclear medicine approaches, in particular using autologous radiolabeled lipoproteins, can be related to histopathological findings; however, they fail to identify lesions at risk. Positron emission tomography (PET) tracers with much better physical properties have been examined, the most detailed information being available for F-18-deoxyglucose (FDG) and F-18-sodium fluoride (NaF).

Loss of serum response factor induces microRNA-mediated apoptosis in intestinal smooth muscle cells.

Serum response factor (SRF) is a transcription factor known to mediate phenotypic plasticity in smooth muscle cells (SMCs). Despite the critical role of this protein in mediating intestinal injury response, little is known about the mechanism through which SRF alters SMC behavior. Here, we provide compelling evidence for the involvement of SRF-dependent microRNAs (miRNAs) in the regulation of SMC apoptosis.

Serum Response Factor Is Essential for Prenatal Gastrointestinal Smooth Muscle Development and Maintenance of Differentiated Phenotype.

Background/aims: Smooth muscle cells (SMCs) characteristically express serum response factor (SRF), which regulates their development. The role of SRF in SMC plasticity in the pathophysiological conditions of gastrointestinal (GI) tract is less characterized.

Methods: We generated SMC-specific Srf knockout mice and characterized the prenatally lethal phenotype using ultrasound biomicroscopy and histological analysis.
