Specific recommendations (or lack thereof) for older patients with cardiovascular disease in the current European Society of Cardiology guidelines

Due to population ageing, the number of older and frail patients with cardiovascular disease is increasing. In the current guidelines of the European Society of Cardiology specific recommendations for this older population are missing or scarce, probably due to limited evidence concerning diagnosis and treatment of cardiovascular disease in older patients. Moreover, recommendations on shared decision making, palliative care and advanced care planning are also essential in these guidelines. In this article we evaluate the current European of Society of Cardiology guidelines (2013–2020) to determine whether specific recommendations for older patients have been included.

Cell-based cardiovascular repair and regeneration in acute myocardial infarction and chronic ischemic cardiomyopathy-current status and future developments

Ischemic heart disease is the main cause of death and morbidity in most industrialized countries. Stem- and progenitor cell-based treatment approaches for ischemic heart disease are therefore an important frontier in cardiovascular and regenerative medicine. Experimental studies have shown that bone-marrow-derived stem cells and endothelial progenitor cells can improve cardiac function after myocardial infarction, clinical phase I and II studies were rapidly initiated to translate this concept into the clinical setting. However, as of now the effects of stem/progenitor cell administration on cardiac function in the clinical setting have not met expectations. Thus, a better understanding of causes of the current limitations of cell-based therapies is urgently required. Importantly, the number and function of endothelial progenitor cells is reduced in patients with cardiovascular risk factors and/or coronary artery disease. These observations may provide opportunities for an optimization of cell-based treatment approaches. This review provides a summary of current evidence for the role and potential of stem and progenitor cells in the pathophysiology and treatment of ischemic heart disease, including the properties, and repair and regenerative capacities of various stem and progenitor cell populations. In addition, we describe modes of stem/progenitor cell delivery, modulation of their homing as well as potential approaches to "prime" stem/progenitor cells for cardiovascular cell-based therapies.     

The effects of Hartcoach, a life style intervention provided by telephone on the reduction of coronary risk factors: a randomised trial

ABSTRACT: BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death worldwide. Secondary prevention is essential, but participation rates for cardiac rehabilitation are low. Furthermore, current programmes do not accomplish that patients with CVD change their lifestyle in a way that their individual risk factors for recurrent events decrease, therefore more effective interventions are needed. In this study, the effectiveness of the Hartcoach-programme, a telephonic secondary prevention program focussing on self management, is studied. Methods/design A multicenter, randomised parallel-group study is being conducted. Participants are 400 patients with acute myocardial infarction (STEMI, NSTEMI,) and patients with chronic or unstable angina pectoris (IAP). Patients are recruited through the participating hospitals and randomly assigned to the experimental group (Hartcoach-programme plus usual care) or the control group (usual care). The Hartcoach-programme consists of a period of six months during which the coach contacts the patient every four to six weeks by telephone. Coaches train patients to take responsibility for the achievement and maintenance of the defined target levels for their particular individual modifiable risk factors. Target levels and treatment goals are agreed by the nurse and patient together. Data collection is blinded and occurs at baseline and after 26 weeks (post-intervention). Primary outcome is change in cardiovascular risk factors (cholesterol, body mass index, waist circumference, blood pressure, physical activity and diet). Secondary outcomes include chances in glucose, HbA1c, medication adherence, selfmanagement and quality of life. DISCUSSION: This study evaluates the effects of the Hartcoach-programme on the reduction of individual risk factors of patients with CVDs. Patients who are not invited to follow a hospital based rehabilitation programme or patients who are unable to adhere to such a programme, may be reached by this home based Hartcoach-programme. If positive results are found, the implementation of the Hartcoach-programme will be extended, having implications for the management of many people with CVD. Trial registration NTR2388.     

Computerized clinical decision support systems for acute care management: A decision-maker-researcher partnership systematic review of effects on process of care and patient outcomes

Background

There is a need to find innovative approaches for translating best practices for chronic disease care into daily primary care practice routines. Primary care plays a crucial role in the prevention and management of cardiovascular disease. There is, however, a substantive care gap, and many challenges exist in implementing evidence-based care. The Improved Delivery of Cardiovascular Care (IDOCC) project is a pragmatic trial designed to improve the delivery of evidence-based care for the prevention and management of cardiovascular disease in primary care practices using practice outreach facilitation.

Methods

The IDOCC project is a stepped-wedge cluster randomized control trial in which Practice Outreach Facilitators work with primary care practices to improve cardiovascular disease prevention and management for patients at highest risk. Primary care practices in a large health region in Eastern Ontario, Canada, were eligible to participate. The intervention consists of regular monthly meetings with the Practice Outreach Facilitator over a one- to two-year period. Starting with audit and feedback, consensus building, and goal setting, the practices are supported in changing practice behavior by incorporating chronic care model elements. These elements include (a) evidence-based decision support for providers, (b) delivery system redesign for practices, (c) enhanced self-management support tools provided to practices to help them engage patients, and (d) increased community resource linkages for practices to enhance referral of patients. The primary outcome is a composite score measured at the level of the patient to represent each practice's adherence to evidence-based guidelines for cardiovascular care. Qualitative analysis of the Practice Outreach Facilitators' written narratives of their ongoing practice interactions will be done. These textual analyses will add further insight into understanding critical factors impacting project implementation.

Discussion

This pragmatic, stepped-wedge randomized controlled trial with both quantitative and process evaluations demonstrates innovative methods of implementing large-scale quality improvement and evidence-based approaches to care delivery. This is the first Canadian study to examine the impact of a large-scale multifaceted cardiovascular quality-improvement program in primary care. It is anticipated that through the evaluation of IDOCC, we will demonstrate an effective, practical, and sustainable means of improving the cardiovascular health of patients across Canada.

How to target uncertainty in Dutch invasive cardiovascular care

Current meetings of the Netherlands Society of Cardiology and the Working Group on Intervention Cardiology have shown that new strategic developments in the Dutch healthcare system have created much turbulence and uncertainty amongst members of the organisations. Both on-site and off-site new cardiac centres with and without surgical backup, respectively, are arising or being planned throughout the Netherlands. These strategic adaptations are related to service delivery failure, despite appropriate quality measures. To understand the reasoning behind this uncertainty and how to deal with it, we need to explore its origin and thinking. Its rationale is based on the assumption that each organisation relies on its ability to survive through innovation and transformation. Cardiologists and cardiac surgeons are key players in a large group of stakeholders participating in the chain of cardiovascular care. In addition, the Dutch healthcare system is deeply embedded in a historical sociopolitical environment. This may explain why ongoing uncertainty may beget more uncertainty. What are the consequences for the content of the route forward?     

Role of thyroid hormones-induced oxidative stress on cardiovascular physiology

Thyroid hormones (THs) play an essential role in the maintenance of cardiovascular homeostasis and are involved in the modulation of cardiac contractility, heart rate, diastolic function, systemic vascular resistance, and vasodilation. THs have actions on cardiovascular physiology through the activation or repression of target genes or the activation of intracellular signals through non-genomic mechanisms. Hyperthyroidism alters certain intracellular pathways involved in the preservation of the structure and functionality of the heart, causing relevant cardiovascular disorders. Reactive oxygen species (ROS) play an important role in the cardiovascular system, but the exacerbated increase in ROS caused by chronic hyperthyroidism together with regulation on the antioxidant system have been associated with the development of cardiovascular dysfunction. In this review, we analyze the role of THs-induced oxidative stress in the cellular and molecular changes that lead to cardiac dysfunction, as well as the effectiveness of antioxidant treatments in attenuating cardiac abnormalities developed during hyperthyroidism.     

Announcing the call for the Special Issue on “Cardiovascular mechanobiology—a special issue to look at the state of the art and the newest insights into the role of mechanical forces in cardiovascular development,physiology, and disease”

This Commentary describes a call for submissions for the upcoming special issue focused on the state of the art of cardiovascular mechanobiology research and the newest insights into the role of mechanical forces in cardiovascular development, physiology, and disease

Cells in the human body are exposed to a variety of different forces which they sense and respond to. This is especially true for the cardiovascular system, where cells react for instance to blood flow, stretching forces from the filling of the heart with blood, or extracellular matrix stiffness. These parameters change throughout development and further in disease, which can dramatically impact the behavior of the sensing cells and the disease progression: blood flow and wall stress are sensed by endothelial cells in the arteries and determine the sites of atherosclerotic plaque formation; reduced ejection fraction leads to excessive stretching of cardiomyocytes in the ventricle with detrimental effects on cardiomyocyte signaling and function; and the cardiac extracellular matrix and also cardiomyocytes themselves stiffen as a response to injuries or diseases and lead to a loss of contractile function.Detailed knowledge of the source and the parameters of the forces as well as the mechanisms used by cells to sense and respond to them can help to understand disease mechanisms and identify to new paths of treating cardiovascular and other diseases. Unsurprisingly, mechanobiology as a discipline dedicated to the study of (sub-) cellular forces, topographies, and mechanically responsive molecules or complexes has been growing in importance. Methods initially being developed and used by only a few specialty labs have become standard techniques in cell and developmental biology. Similarly, the field of cardiovascular biology has seen a strong increase in publications related to mechanobiology over the past decades. This special issue is aiming to take stock at the recent developments and current state of the art of cardiovascular mechanobiology and will cover all topics related to the investigation into the role of mechanical forces in cardiovascular development, physiology, and disease.The Special Issue will be prepared and edited by the current authors (Pamela Swiatlowska and Thomas Iskratsch).     

Developments for a growing Japanese patient population: facilitating new technologies for future health care

Lung cancer, COPD and cardiovascular diseases are highlighted as some of the most common disease that cause mortality, and for that reason are the most active areas for drug development. This perspective paper overviews the urgent need to develop a health care system for a rapidly growing patient population in Japan, including forthcoming demands on clinical care, expecting outcomes, and economics. There is an increasing requirement to build on the strengths of the current health care system, thereby delivering urgent solutions for the future. There is also a declaration from the Ministry of Health, Labour and Welfare (MHLW), to develop new biomarker diagnostics, which is intended for patient stratification, aiding in diagnostic phenotype selection for responders to drug treatment of Japanese patients. This perspective was written by the panel in order to introduce novel technologies and diagnostic capabilities with successful implementation. The next generation of personalized drugs for targeted and stratified patient treatment will soon be available in major disease areas such as, lifestyle-related cancers, especially lung cancers with the highest mortality including a predisposing disorder chronic obstructive pulmonary disease, cardiovascular disease, and other diseases. Mass spectrometric technologies can provide the "phenotypic fingerprint" required for the concept of Personalized Medicine. Mass spectrometry-driven target biomarker diagnoses in combination with high resolution computed tomography can provide a critical pathway initiative facilitated by a fully integrated e-Health infrastructure system. We strongly recommend integrating validated biomarkers based on clinical proteomics, medical imaging with clinical care supported by e-Health model to support personalized treatment paradigms to reduce mortality and healthcare costs of chronic and co-morbid diseases in the elderly population of Japan.     

Biomarkers for cardiovascular disease: challenges and future directions

The accurate diagnosis and prevention of cardiovascular disease (CVD) is an important public health goal. Although clinical characteristics such as age and gender are well-established risk factors for CVD, such features are not sufficient to identify all patients at risk. Cardiovascular biomarkers have the potential to augment clinical risk stratification by aiding in screening, diagnosis and assessment of prognosis. However, most current biomarkers have only modest predictive value, and there is a need to identify additional biomarkers from new biological pathways. The availability of platforms for profiling DNA, RNA, proteins and metabolites in clinical specimens has facilitated the 'unbiased' search for new biomarkers, which can now be tested in a clinical setting. This review highlights recent developments in the field of cardiovascular biomarkers and describes the use of new technologies for the identification of biomarkers.     

Molecular pathogenesis of chronic myeloid leukaemia

The abnormal haemopoietic precursor cells of chronic myeloid leukaemia (CML) carry the cytogenetic abnormality [t(9;22)(q34;q11)]--a reciprocal translocation that results in the expression of a chimaeric protein derived from the fused BCR and ABL genes. This Bcr-Abl protein tyrosine kinase mediates an array of effects on signal transduction pathways affecting cell survival, proliferation, adhesion and genetic stability. The end-result of these abnormal signalling processes is a bi- or triphasic clinical disease. Initially, CML is characterised by the presence of an excess of myeloid progenitor cells and their mature progeny. This chronic phase of CML is followed, either directly or with an intervening 'accelerated phase', by a stage where primitive blast cells predominate (acute transformation). This review discusses the role of Bcr-Abl-mediated signalling events in cellular transformation, genetic instability and disease progression in CML, and describes current developments in CML treatment using a Bcr-Abl inhibitor.     

Apelin: a new plasma marker of cardiopulmonary disease

OBJECTIVES: Dyspnea is a major symptom of both parenchymal lung disease and chronic heart failure. Underlying cardiac dysfunction can be assessed by measurement of cardiac-derived B-type natriuretic peptide or its precursor in plasma. However, no specific endocrine marker of the lung parenchyma has so far been identified. We therefore examined whether plasma concentrations of apelin, a novel inotropic hormone, is affected in patients with chronic parenchymal lung disease without cardiac dysfunction. METHODS AND RESULTS: Patients with severe chronic parenchymal lung disease and normal cardiac function (n=53), idiopathic pulmonary hypertension with increased right ventricular pressure (n=10), and patients with severe left ventricular systolic dysfunction (n=22) were enrolled. Plasma apelin-36 and proBNP concentrations were measured with radioimmunoassays. While proBNP plasma concentrations were unaffected in chronic parenchymal lung disease patients compared to normal subjects, the apelin-36 concentration was reduced 3.3-fold (median 35 pmol/l (0-162 pmol/l) vs. 117 pmol/l (55-232 pmol/l), P<0.001). Moreover, the apelin-36 concentration was decreased in chronic heart failure patients (2.1-fold, P<0.01) and in patients with idiopathic pulmonary hypertension (4.0-fold, P<0.001). In contrast, the proBNP concentration was highly increased in both chronic heart failure and idiopathic pulmonary hypertension patients. CONCLUSION: Plasma concentrations of apelin-36, a novel inotropic peptide, are decreased in patients with chronic parenchymal lung disease and preserved cardiac function. Combined measurement of apelin-36 and proBNP may be a new diagnostic approach in distinguishing pulmonary from cardiovascular causes of dyspnea.     

The future of the management of ischaemic heart disease.

Ischaemic heart disease will kill over 150,000 people in the next year in Britain, more than any other single disease process, and cost more than 1.4bn pounds in health care alone. Faced with the continuing problems arising from ischaemic heart disease cardiological clinician scientists are moving from technology based solutions to basic sciences. This article explains how basic science may contribute to new understanding and treatments for patients with ischaemic heart disease. Highlighted are three problems which face any clinical cardiologist on a daily basis and for which basic science may provide solutions: the uncertainty of plaque stability in coronary disease; restenosis after percutaneous transluminal angioplasty; and the shortage of organs for cardiac transplant programmes for patients with heart failure.     

OPTImal CArdiac REhabilitation (OPTICARE) following Acute Coronary Syndromes: Rationale and design of a randomised, controlled trial to investigate the benefits of expanded educational and behavioural intervention programs

The majority of cardiac rehabilitation (CR) referrals consist of patients who have survived an acute coronary syndrome (ACS). Although major changes have been implemented in ACS treatment since the 1980s, which highly influenced mortality and morbidity, CR programs have barely changed and only few data are available on the optimal CR format in these patients. We postulated that standard CR programs followed by relatively brief maintenance programs and booster sessions, including behavioural techniques and focusing on incorporating lifestyle changes into daily life, can improve long-term adherence to lifestyle modifications. These strategies might result in improved (cardiac) mortality and morbidity in a cost-effective fashion. In the OPTImal CArdiac REhabilitation (OPTICARE) trial we will assess the effects of two advanced and extended CR programs that are designed to stimulate permanent adaption of a heart-healthy lifestyle, compared with current standard CR, in ACS patients. We will study the effects in terms of cardiac risk profile, levels of daily physical activity, quality of life and health care consumption.     

Role of apoptosis in cardiovascular disease

Apoptosis plays a key role in the pathogenesis in a variety of cardiovascular diseases due to loss of terminally differentiated cardiac myocytes. Cardiac myocytes undergoing apoptosis have been identified in tissue samples from patients suffering from myocardial infarction, diabetic cardiomyopathy, and end-stage congestive heart failure. Apoptosis is a highly regulated program of cell death and can be mediated by death receptors in the plasma membrane, as well as the mitochondria and the endoplasmic reticulum. The cell death program is activated in cardiac myocytes by various stressors including cytokines, increased oxidative stress and DNA damage. Many studies have demonstrated that inhibition of apoptosis is cardioprotective and can prevent the development of heart failure. This review provides a current overview of the evidence of apoptosis in cardiovascular diseases and discusses the molecular pathways involved in cardiac myocyte apoptosis.     

Diabetes mellitus associated cardiovascular signalling alteration: A need for the revisit

Diabetes mellitus, a chronic metabolic disorder, is recognized as a root cause of cardiovascular disorders. A long-term and uncontrolled diabetes mellitus coincides with the cardiovascular signalling alteration, resulting in inadequacy of maintaining the cardiovascular physiology. Nitric oxide (NO) is an imperative mediator of cardiovascular physiology as its signalling is known to mediate vasodilatory, anti-platelet, anti-proliferative, and anti-inflammatory actions in vessels. In 1998, Robert Furchgott, Louis Ignarro and Ferid Murad received the Nobel Prize in Medicine or Physiology for their great discoveries concerning the role of NO (originally identified as endothelium-derived relaxing factor, EDRF) as a key signalling molecule in regulating cardiovascular physiology. The activation of phosphatidylinositol 3-kinase (PI3-K) further activates protein kinase B (PKB/Akt), which subsequently enhances eNOS activation and vascular NO generation. However, in recent studies a marked impairment in PI3-K/Akt–eNOS–NO signalling has been demonstrated in the condition of diabetes mellitus. Therefore, the defective PI3-K–Akt–eNOS–NO signalling pathways could make diabetic patients more vulnerable to cardiovascular disease pathology concerning the key functions of NO. Adenosine produced by cardiac cells has abilities to attenuate the proliferation of cardiac fibroblasts, inhibit collagen synthesis, and defend the myocardium against ischemia–reperfusion injury. However, diabetes mellitus is associated with enhanced unidirectional uptake of interstitial adenosine and reduced ability to release adenosine by cardiac cells during ATP deprivation. The reduced myocardial extracellular availability and increased uptake of adenosine could make diabetic subjects more susceptible to myocardial abnormalities. This review throws lights on diabetes mellitus-associated cardiovascular signalling alterations and their possible contribution to cardiovascular disease pathology.     

Caloric restriction: powerful protection for the aging heart and vasculature

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the United States. Research has shown that the majority of the cardiometabolic alterations associated with an increased risk of CVD (e.g., insulin resistance/type 2 diabetes, abdominal obesity, dyslipidemia, hypertension, and inflammation) can be prevented, and even reversed, with the implementation of healthier diets and regular exercise. Data from animal and human studies indicate that more drastic interventions, i.e., calorie restriction with adequate nutrition (CR), may have additional beneficial effects on several metabolic and molecular factors that are modulating cardiovascular aging itself (e.g., cardiac and arterial stiffness and heart rate variability). The purpose of this article is to review the current knowledge on the effects of CR on the aging of the cardiovascular system and CVD risk in rodents, monkeys, and humans. Taken together, research shows that CR has numerous beneficial effects on the aging cardiovascular system, some of which are likely related to reductions in inflammation and oxidative stress. In the vasculature, CR appears to protect against endothelial dysfunction and arterial stiffness and attenuates atherogenesis by improving several cardiometabolic risk factors. In the heart, CR attenuates age-related changes in the myocardium (i.e., CR protects against fibrosis, reduces cardiomyocyte apoptosis, prevents myosin isoform shifts, etc.) and preserves or improves left ventricular diastolic function. These effects, in combination with other benefits of CR, such as protection against obesity, diabetes, hypertension, and cancer, suggest that CR may have a major beneficial effect on health span, life span, and quality of life in humans.
