OBJECTIVES: This study aimed to determine the association of stage B heart failure (SBHF) and its constituent left ventricular (LV) abnormalities with trajectory of exercise capacity over time, and assess whether this association is modified by reversion of these LV abnormalities to normal. BACKGROUND: The LV abnormalities of SBHF may coincide with a reduction in exercise capacity that precedes the overt exercise intolerance of clinical heart failure (HF). Determining the predictive capacity of established and novel SBHF criteria for exercise capacity decline may improve HF risk stratification...

Ventricular arrhythmias are responsible for hundreds of thousands of deaths every year. Catheter ablation of ventricular tachycardia (VT) is an essential component of the management of these life-threatening arrhythmias. However, in many patients, despite medical and interventional therapy, VT recurs. Further, some VT substrates (mid-myocardial, left ventricular summit, intra-septal) are not easily targeted, due to limitations of currently available technology. In certain clinical settings, ventricular fibrillation (VF) episodes that have premature ventricular contraction (PVC) triggers can also be targeted with catheter ablation...

Regardless of advances in medical and interventional treatment of cardiovascular disease (CVD), a limited number of patients attend a cardiac rehabilitation (CR) programme on a regular basis. Due to modern therapies more individuals will be surviving an acute cardiovascular event, but the expected burden of chronic heart failure will be increasing worldwide.However, both in high- and low-income countries, secondary prevention after an acute myocardial infarction or stroke has been implemented in less than a half of eligible patients...

Heart failure (HF) is a chronic health condition that causes significant morbidity among older adults, many of whom receive support and care from an informal caregiver. Caregiving is a difficult role with many responsibilities and challenges. An in-depth understanding of these challenges is necessary to develop services, resources, and interventions for HF caregivers. The goal of this study was to qualitatively ascertain the most significant challenges facing HF caregivers. We conducted semi-structured interviews with 16 caregivers of a person with HF (PHF)...

Nucleic acid (NA)-sensing Toll-like receptors (TLRs) respond to DNA/RNA derived from pathogens and dead cells. Structural studies have revealed a variety of molecular mechanisms by which TLRs sense NAs. Double-stranded RNA and single-stranded DNA directly bind to TLR3 and TLR9, respectively, whereas TLR7 and 8 bind to nucleosides and oligoribonucleotides derived from RNAs. Activation of ligand-bound TLRs is influenced by the functional status of TLRs. Proteolytic cleavage of NA-sensing TLRs enables ligand-dependent TLR dimerization...

Heart failure is a major cause of morbidity and mortality in type 2 diabetes. Type 2 diabetes contributes to the development of heart failure through a variety of mechanisms, including disease specific myocardial structural, functional and metabolic changes. This review will focus on the contemporary contributions of state of the art non-invasive technologies to our understanding of diabetic cardiomyopathy, including data on cardiac disease phenotype, cardiac energy metabolism and energetic deficiency, ectopic and visceral adiposity, diabetic liver disease, metabolic modulation strategies, and cardiovascular outcomes with new classes of glucose lowering therapies...

PURPOSE OF REVIEW: Interventional techniques have been developed for a wide spectrum of mechanisms of heart failure (HF), especially in valvular heart disease and cardiomyopathies (ischaemic cardiomyopathy and hypertrophic cardiomyopathy). In this article, we review recent reports on catheter interventions to treat patients with HF. RECENT FINDINGS: Direct modification using the Parachute device and the REVIVENT-TC device for patients with impaired left ventricle with large infarct scars improves geometry and haemodynamic efficiency, resulting in a reduction of HF symptoms...

Congenital heart disease (CHD) is a problem in the structure of the heart that is present at birth. Due to advances in interventional cardiology, CHD may currently be without surgery. The present study aimed to explore the molecular mechanism underlying CHD. A total of 200 cases of CHD treated by transcatheter closure as well as 200 controls were retrospectively assessed. Serum cytokines prior to and after treatment were assessed by reverse-transcription quantitative polymerase chain reaction analysis. Furthermore, the levels of proteins associated with c-Jun N-terminal kinase (JNK) and nuclear factor (NF)-κB were assessed by western blot analysis and immunohistochemistry...

Pharmacological interventions for heart failure with preserved ejection fraction (HFpEF) have failed to reduce mortality and hospitalization. Evidence for mineralocorticoid antagonists (MRAs), β-adrenoceptor blockers (β-blockers), and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs)-to reduce clinical outcomes in HFpEF remains unclear. We conducted a systematic search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Clinical Trials.gov for randomized controlled trials (RCTs) assessing pharmacological treatments in HFpEF diagnosed according the recommendations of the European Society of Cardiology (ESC) 2016 guidelines from inception to August, 2017...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

BACKGROUND: A previous Cochrane review has shown that exercise-based cardiac rehabilitation (CR) can benefit myocardial infarction and post-revascularisation patients. However, the impact on stable angina remains unclear and guidance is inconsistent. Whilst recommended in the guidelines of American College of Cardiology/American Heart Association and the European Society of Cardiology, in the UK the National Institute for Health and Care Excellence (NICE) states that there is "no evidence to suggest that CR is clinically or cost-effective for managing stable angina"...

Heart failure patients are predisposed to develop arrhythmias. Supraventricular arrhythmias can exacerbate the heart failure symptoms by decreasing the effective cardiac output and their control require pharmacological, electrical, or catheter-based intervention. In the setting of atrial flutter or atrial fibrillation, anticoagulation becomes paramount to prevent systemic or cerebral embolism. Patients with heart failure are also prone to develop ventricular arrhythmias that can present a challenge to the managing clinician...

BACKGROUND: In addition to pain, sickle cell anaemia (HbSS) complications include neurocognitive difficulties in attention and processing speed associated with low daytime and night-time oxygen saturation compounded by obstructive sleep apnoea (OSA). In the general population OSA is treated with continuous positive airways pressure (CPAP). The aim of this single-blind, randomised, controlled phase II trial is to compare auto-adjusting CPAP (APAP) with standard care to standard care alone in individuals with HbSS to determine whether the intervention improves attention and processing speed, brain structure, pain and quality of life...

OBJECTIVES: After injury, many children experience posttraumatic stress symptoms (PTSS) that negatively impact recovery. Acute pain and PTSS share neurobiological pathways, and acute dosage of morphine has been linked to reduced PTSS in naturalistic studies. However, the complex interactions between pain, morphine and other opioid use, and PTSS have yet to be investigated in robust pediatric samples.This prospective, longitudinal study examined relationships between acute pain, opioid medications, and PTSS after pediatric injury...

AIMS AND OBJECTIVES: The purpose of this study was to explore the psychological impact of parenting a child with a critical congenital heart defect (CHD), and the feasibility and acceptability of integrating psychological services into pediatric cardiology care. BACKGROUND: Children with critical CHD are at an increased risk for long-term behavioral, social, and emotional difficulties. Data suggest that this risk is partially attributable to parental mental health, which is a stronger predictor of long-term behavioral problems in CHD children than disease-specific and surgical factors...
