The prevalence of sleep-disordered breathing (SDB) is high in patients with cardiovascular diseases. Typical symptoms like daytime sleepiness can be absent and those patients may report unspecific, therapy-resistant symptoms related to their underlying disease. Particularly sleep-related symptoms like nocturia, nocturnal dyspnea and pectangina can be present. Based on the results of recently published studies, the treatment of central sleep apnea in patients with symptomatic, systolic heart failure by adaptive servo-ventilation is no longer recommended...

In the latter part of the 20th century, drug development in cardiovascular diseases (CVDs) was a paragon of "modern" therapeutics, bringing about a substantial number of effective, well-tolerated agents targeting some of the most prevalent diseases of the Western world. These drugs were often examples of rational drug development targeting specific pathophysiologic pathways previously elucidated through basic research (e.g., targeting of the renin-angiotensin system or the cholesterol synthesis pathway). The widespread adoption of these ground-breaking medications in practice and into medical guidelines undoubtedly played a role in the fall of morbidity and mortality from CVD in the United States in recent decades...

The medical burden of heart failure (HF) has spurred interest in clinicians and scientists to develop therapies to restore the function of a failing heart. To advance this agenda, the National Heart, Lung, and Blood Institute (NHLBI) convened a Working Group of experts from June 2 to 3, 2016, in Bethesda, Maryland, to develop NHLBI recommendations aimed at advancing the science of cardiac recovery in the setting of mechanical circulatory support (MCS). MCS devices effectively reduce volume and pressure overload that drives the cycle of progressive myocardial dysfunction, thereby triggering structural and functional reverse remodeling...

The increasing rate of cardiovascular diseases, the improved survival after the acute phase, the aging of the population and the implementation of primary prevention caused an exponential increase in outpatient cardiac performance, thereby making it difficult to maintain a balance between the citizen-patient request and the economic sustainability of the healthcare system. On the other side, the prescription of many diagnostic tests with a view to defensive medicine and the related growth of patients' expectations, has led several scientific societies to educational campaigns highlighting the concept that "less is more"...

BACKGROUND: XuefuZhuyu decoction (XFZY) is a well-known traditional Chinese herbal medicine for the treatment of various cardiovascular diseases, such as unstable angina pectoris and myocardial ischemia-reperfusion injury. However, the mechanism by which XFZY contributes to the amelioration of cardiac injury remains unclear. METHODS: H9C2 cells were cultured under the hypoxic condition for 10 h and reoxygenated for 2 h. In the presence of various concentrations of XFZY for 12 h, the cell viability was measured by MTT assay...

Hypertension and cardiovascular complications are the leading causes of death worldwide. Antihypertensive drugs often cause various side effects, and improper use of antihypertensive medications can result in irreparable damage. Edible fungi of the Monascus species have been used as traditional Chinese medicines in Southeast Asia for several centuries. The fermented products of Monascus purpureus NTU 568 (ANKASCIN 568) possess a number of functional secondary metabolites including the anti-inflammatory pigments monascin and ankaflavin...

Chronic kidney disease (CKD) patients have a high burden of cardiovascular disease. In the general population, lipid metabolism disorders, which cause the initiation and progression of atherosclerotic vascular changes, are major targets for preventive and therapeutic strategies in cardiovascular medicine. However, data from large cohort studies and from clinical trials suggest that the treatment guidelines on cardiovascular disease prevention and therapy cannot uncritically be transferred from individuals with intact renal function to CKD patients...

Cancer remains a major health hurdle worldwide and has moved from the third leading cause of death in the year 1990 to second place after cardiovascular disease since 2013. Chemotherapy is one of the most widely used treatment modes; however, its efficiency is limited due to the resistance of cancer cells to cytotoxic agents. The present overview deals with the potential of the flora of Central, Eastern and Western African (CEWA) regions as resource for anticancer drug discovery. It also reviews the molecular targets of phytochemicals of these plants such as ABC transporters, namely P-glycoprotein (P-gp), multi drug-resistance-related proteins (MRPs), breast cancer resistance protein (BCRP, ABCG2) as well as the epidermal growth factor receptor (EGFR/ErbB-1/HER1), human tumor suppressor protein p53, caspases, mitochondria, angiogenesis, and components of MAP kinase signaling pathways...

INTRODUCTION: Cigarette smoking is one of the leading causes of early death in the UK and worldwide. Public health guidance recommends the use of varenicline, bupropion and nicotine replacement therapy (NRT) as smoking cessation aids in the UK. Additionally, the first electronic cigarette has been licensed for use as a smoking cessation medicine. However, there are ongoing concerns about the safety of these medicines. We present a protocol for a systematic review and network meta-analysis (NMA) to determine how these smoking cessation medicines compare to each other with respect to their neuropsychiatric safety in adult smokers...

The observation that "one size does not fit all" for the prevention and treatment of cardiovascular disease, among other diseases, has driven the concept of precision medicine. The goal of precision medicine is to provide the best-targeted interventions tailored to an individual's genome. The human genome is composed of billions of sequence arrangements containing a code that controls how genes are expressed. This code depends on other nonstatic regulators that surround the DNA and constitute the epigenome...

BACKGROUND: Appropriate dissemination of clinical data is crucial for minimising bias. Despite this, high rates of study discontinuation and non-publication have been reported among clinical trials. Cardiovascular medicine receives a substantial proportion of academic funding; however, predictors of non-publication among cardiovascular trials are not well-established. METHODS: The National Clinical Trials database was searched for cardiovascular trials completed between January 2010 and January 2014...

The cucurbitaceous plant Momordica charantia L., named "bitter melon", inhabits Asia, Africa, and South America and has been used as a traditional medicine. The atypical proliferation of vascular smooth muscle cells (VSMCs) plays an important role in triggering the pathogenesis of cardiovascular diseases. Platelet-derived growth factor (PDGF) is regarded as the most powerful growth factor in promoting the intimal accumulation of VSMCs. The current study features the identification of six new cucurbitane-type triterpenoids (1-6) from the fruits of M...

Masutaka Furue, Takafumi Kadono
BACKGROUND: Comorbidities of cardiovascular diseases (CVDs), metabolic syndrome and autoimmune diseases with systemic inflammation are recent topics in medicine. Inflammatory skin diseases such as atopic dermatitis and psoriasis are an active source of diverse proinflammatory cytokines and chemokines, which are readily detectable in the circulation and are likely to be involved in developing comorbidities. EVIDENCE: Both atopic dermatitis and psoriasis are frequently comorbid with CVD, metabolic syndrome and autoimmune diseases, the consequence of which is called "inflammatory skin march", "psoriatic march" or "march of psoriasis"...

Congenital heart defects (CHDs) affect approximately 1% of live births and are a major source of childhood morbidity and mortality even in countries with advanced healthcare systems. Along with phenotypic heterogeneity, the underlying etiology of CHDs is multifactorial, involving genetic, epigenetic, and/or environmental contributors. Clear dissection of the underlying mechanism is a powerful step to establish individualized therapies. However, the majority of CHDs are yet to be clearly diagnosed for the underlying genetic and environmental factors, and even less with effective therapies...
