The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension (PH) are also valid for Germany. While the guidelines contain detailed recommendations regarding clinical aspects of pulmonary arterial hypertension (PAH) and other forms of PH, they contain only a relatively short paragraph on novel findings on the pathobiology, pathology, and genetics. However, these are of great importance for our understanding of this complex disease both from a clinical and scientific point of view, and they are essential for the development of novel treatment strategies...

Importance: Kawasaki disease (KD) is the most recognized vasculitis of childhood. The condition's characteristic high fever, rash, mucositis, conjunctivitis, lymphadenopathy, and extremity changes are superficially unexceptional, and resolve spontaneously within a mean of 12 days. It is the acuity and the potential for life-changing damage to the coronary arteries that distinguish KD from conditions that mimic it and exemplify the unique aspects and challenges of vascular inflammation in children...

Although relatively rare, inherited primitive cardiac disorders (IPCDs) in athletes have a deep social impact since they often present as sudden cardiac death (SCD) of young and otherwise healthy persons. The diagnosis of these conditions is likely underestimated due to the lack of shared clinical criteria and to the existence of several borderline clinical pictures. We will focus on the clinical and molecular diagnosis of the most common IPCDs, namely hypertrophic cardiomyopathies, long QT syndrome, arrhythmogenic right ventricular cardiomyopathy, and left ventricular non-compaction...

BACKGROUND: Anderson-Fabry disease (AFD) is a rare X-linked lysosomal storage disease, caused by defects of the alpha-galactosidase A (GLA) gene. AFD can affect the heart, brain, kidney, eye, skin, peripheral nerves, and gastrointestinal tract. Cardiology (hypertrophic cardiomyopathy), neurology (cryptogenic stroke), and nephrology (end-stage renal failure) screening studies suggest the prevalence of GLA variants is 0.62%, with diagnosis confirmation in 0.12%. OBJECTIVES: This study sought to expand screening from these settings to include ophthalmology, dermatology, gastroenterology, internal medicine, pediatrics, and medical genetics to increase diagnostic yield and comprehensively evaluate organ involvement in AFD patients...

BACKGROUND: Friedreich ataxia is a rare inherited autosomal recessive neurological disorder, characterised initially by unsteadiness in standing and walking, slowly progressing to wheelchair dependency usually in the late teens or early twenties. It is associated with slurred speech, scoliosis, and pes cavus. Heart abnormalities cause premature death in 60% of people with the disorder. There is no easily defined clinical or biochemical marker and no known treatment. This is the second update of a review first published in 2009 and previously updated in 2012...

In the past ten years large scale genotyping has led to discoveries of sequence variants that confer risk of many common and complex diseases. Due to pioneering work done, in large part, at deCODE genetics in Reykjavik, discoveries from Iceland have contributed substantially to key advances in population genetics. In cardiovascular medicine a number of discoveries have been made, uncovering sequence variants that are associated with disorders such as coronary artery disease, atrial fibrillation, sick sinus syndrome, peripheral vascular disease, aortic aneurysm and ischemic stroke...

Despite decades of progress, congenital heart disease remains a major cause of mortality and suffering in children and young adults. Prevention would be ideal, but formidable biological and technical hurdles face any intervention that seeks to target the main causes, genetic mutations in the embryo. Other factors, however, significantly modify the total risk in individuals who carry mutations. Investigation of these factors could lead to an alternative approach to prevention. To define the risk modifiers, our group has taken an "experimental epidemiologic" approach via inbred mouse strain crosses...

Importance: Oncocardiology is a medical discipline that focuses on the identification, prevention, and treatment of cardiovascular complications related to cancer therapy. This discipline has gained interest from the cardiology community in recent years because of a remarkable increase in the number of cancer survivors and the proliferation of new cancer therapies causing cardiovascular complications, such as hypertension, heart failure, vascular complications, and cardiac arrhythmia...

The aim of the present study was to undertake a study on the prevalence of cytochrome P450 2D6 (CYP2D6) poor metabolizer alleles (*3, *4, *5, and *6) on a Montenegrin population and its impact on developing adverse drug reactions (ADRs) of β-blockers in a hospitalized cardiac patient population. A prospective study was conducted in the Cardiology Center of the Clinical Center of Montenegro and included 138 patients who had received any β-blocker in their therapy. ADRs were collected using a specially designed questionnaire, based on the symptom list and any signs that could point to eventual ADRs...

Ventricular arrhythmias without structural heart disease are responsible for ∼35% of patients who have sudden cardiac death before the age of 40 years. Molecular autopsy and/or cardiological investigation of nearby family members often reveals the diagnosis and genetic testing can be helpful in family screening and risk stratification in disease carriers. Extended gene panels can be screened in a short period of time at low cost. A multidisciplinary team of (genetically) specialized clinicians is necessary to judge all the available details and to decide on the significance of the variant and further strategies...

Hypertrophic Cardiomyopathy (HCM) is an inherited cardiovascular disorder of great genetic heterogeneity and has a prevalence of 0.1 - 0.2 % in the general population. Several hundred mutations in more than 27 genes, most of which encode sarcomeric structures, are associated with the HCM phenotype. Then, HCM is an extremely heterogeneous disease and several phenotypes have been described over the years. Originally only two phenotypes were considered, a more common, obstructive type (HOCM, 70 %) and a less common, non-obstructive type (HNCM, 30 %) (Maron BJ, et al...

BACKGROUND: Polymorphisms which are presented below may be the cause of inherited thrombophilia and may result in pregnancy loss. The hypothesis is based on a number of cardiology studies which have confirmed the involvement of these polymorphisms in thrombotic incidents. OBJECTIVES: To evaluate the role of polymorphisms of factor VII gene (Arg353Gln, -122T > C) and PAI-1 gene (-675 4G/5G) in the etiology of recurrent miscarriage. MATERIAL AND METHODS: The study group included 152 women with a positive history of ≥ 2 consecutive pregnancy losses (114 and 38 women with 2 and ≥ 3 miscarriages, respectively), while 180 healthy women were recruited as controls...

The 2013 American College of Cardiology/American Heart Association guidelines on cholesterol management have placed greater emphasis on high-intensity statin dosing for those with known cardiovascular disease or diabetes mellitus. Differences in risk of hepatotoxicity, new onset diabetes and rhabdomyolysis specifically between the high-intensity statins and the most common moderate-intensity statin, simvastatin, were not found to a significant degree in this review. Rather, baseline characteristics and drug-drug interactions (DDIs) appear to be more important regarding the risk of these adverse effects...

Acromegaly is a rare disease, mostly caused by a growth hormone (GH)-secreting benign pituitary tumor, with an increased production of GH and insulin-like growth factor 1 (IGF-1). Cardiovascular complications are common and are associated with cardiomyocyte apoptosis and concentric cardiac hypertrophy. Suppression of GH and IGF-1 appears to improve cardiac function only in the short term, with little or no decrease in left ventricular mass or improvement in cardiac function after prolonged treatment. Alcohol septal ablation (ASA) has emerged as a minimally invasive alternative to septal myectomy, with significant improvement in symptoms, gradients and left ventricular remodeling...

Hypertrophic cardiomyopathy (HCM) is a relatively common genetic heart disease encumbered throughout much of its almost 60-year history by a large measure of misunderstanding and the perception of a grim outcome without effective treatment options. However, it is now apparent that the majority of patients affected with HCM can achieve normal or near-normal life expectancy without disability, and usually do not require major treatment interventions. Nevertheless, for those patients with HCM who are at risk for (or experience) disease-related complications, a constellation of comprehensive nonpharmacologic management strategies have evolved over the last 15 years, altering the natural history and disease course for many, including implantable defibrillators, heart transplant, external defibrillation/therapeutic hypothermia, advances in surgical myectomy, and alcohol ablation...

Congenital heart defects (CHDs) are common birth defects and result in significant morbidity and global economic impact. Genetic factors play a role in most CHDs; however, identification of these factors has been historically slow due to technological limitations and incomplete understanding of the impact of human genomic variation on normal and abnormal cardiovascular development. The advent of chromosome microarray (CMA) brought tremendous gains in identifying chromosome abnormalities in a variety of human disorders and is now considered part of a standard evaluation for individuals with multiple congenital anomalies and/or neurodevelopmental disorders...
