Race- and Ethnicity-Related Differences in Heart Failure With Preserved Ejection Fraction Using Natural Language Processing.

Background: Heart failure with preserved ejection fraction (HFpEF) is the predominant form of HF in older adults. It represents a heterogenous clinical syndrome that is less well understood across different ethnicities.

Objectives: This study aimed to compare the clinical presentation and assess the diagnostic performance of existing HFpEF diagnostic tools between ethnic groups.

Assessing the association between genetic and phenotypic features of dilated cardiomyopathy and outcome in patients with coronary artery disease.

Aims: To examine the relevance of genetic and cardiovascular magnetic resonance (CMR) features of dilated cardiomyopathy (DCM) in individuals with coronary artery disease (CAD).

Methods And Results: This study includes two cohorts. First, individuals with CAD recruited into the UK Biobank (UKB) were evaluated.

Torrential mitral regurgitation following right ventricular apical pacing in rheumatic mitral valve disease: a case report.

Background: Mitral regurgitation may develop or worsen following right ventricular apical pacing due to dyssynchronous left ventricular contraction. Pre-existing secondary mitral annular dilation is a well-recognized and important contributing factor. This description of pacing-induced torrential mitral regurgitation in the setting of rheumatic mitral valve disease is a rare case in which a primary mitral valve lesion was the antecedent mechanism.

Sleep-disordered breathing and cardiovascular disease: who and why to test and how to intervene?

Sleep-disordered breathing (SDB) is common in individuals with established cardiovascular disease (CVD), particularly those with heart failure (HF). There are two main types of SDB, central sleep apnoea (CSA) and obstructive sleep apnoea (OSA) which frequently overlap as mixed SDB. Investigating for SDB could be considered in patients with excessive daytime sleepiness, male sex, high body mass index, low ejection fraction, atrial fibrillation (AF), in patients with no dipping blood pressure pattern, recurrent paroxysms of nocturnal dyspnoea or when an apnoea is witnessed.

Decongestion strategies in patients presenting with acutely decompensated heart failure: A worldwide survey among physicians.

Aims: Decongestion strategies for acute decompensated heart failure (ADHF) characterized by volume overload differ widely. The aim of this independent international academic web-based survey was to capture the therapeutic strategies that physicians use to treat ADHF and to assess differences in therapeutic approaches between cardiologists versus non-cardiologists.

Methods And Results: Physicians were invited to complete a web-based questionnaire, capturing anonymized data on physicians' characteristics and treatment preferences based on a hypothetical clinical scenario of a patient hospitalized with ADHF.

Iatrogenic Tricuspid Regurgitation Associated With Pacemakers: A Case Compounded by Tricuspid Stenosis.

A patient presented with severe tricuspid regurgitation 20 years after dual-chamber pacing. Transesophageal echocardiography suggested ventricular pacing wire adherence to the tricuspid valve (TV) and atrial wire prolapse across the tricuspid annulus. Surgical extraction of the pacing wires revealed TV commissural fusion and subvalvular thickening causing tricuspid stenosis, requiring TV replacement.

Comprehensive Phenotypic Characterization of Late Gadolinium Enhancement Predicts Sudden Cardiac Death in Coronary Artery Disease.

Background: Late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) offers the potential to noninvasively characterize the phenotypic substrate for sudden cardiac death (SCD).

Objectives: The authors assessed the utility of infarct characterization by CMR, including scar microstructure analysis, to predict SCD in patients with coronary artery disease (CAD).

Methods: Patients with stable CAD were prospectively recruited into a CMR registry.

Assessment of left ventricular tissue mitochondrial bioenergetics in patients with stable coronary artery disease.

Recurrent myocardial ischemia can lead to left ventricular (LV) dysfunction in patients with coronary artery disease (CAD). In this observational cohort study, we assessed for chronic metabolomic and transcriptomic adaptations within LV myocardium of patients undergoing coronary artery bypass grafting. During surgery, paired transmural LV biopsies were acquired on the beating heart from regions with and without evidence of inducible ischemia on preoperative stress perfusion cardiovascular magnetic resonance.

Paradoxical Left-to-Right Device Embolization Complicating Transcatheter Mitral Valve Edge-to-Edge Repair.

We describe an unusual presentation of transcatheter mitral valve edge-to-edge repair device embolization into the left common femoral vein in a patient with primary degenerative mitral regurgitation. We hypothesize a possible mechanism for this phenomenon, factors that may increase the risk of this complication, and outline the patient's clinical course. ().

Changes in clinical and imaging variables during withdrawal of heart failure therapy in recovered dilated cardiomyopathy.

Aims: This study aimed to profile the changes in non-invasive clinical, biochemical, and imaging markers during withdrawal of therapy in patients with recovered dilated cardiomyopathy, providing insights into the pathophysiology of relapse.

Methods And Results: Clinical, biochemical, and imaging data from patients during phased withdrawal of therapy in the randomized or single-arm cross-over phases of TRED-HF were profiled. Clinical variables were measured at each study visit and imaging variables were measured at baseline, 16 weeks, and 6 months.

Heart Rate as a Marker of Relapse During Withdrawal of Therapy in Recovered Dilated Cardiomyopathy.

Objectives: The objective of this study was to determine the relationship between heart rate and relapse among patients in the TRED-HF (Therapy withdrawal in REcovered Dilated cardiomyopathy trial).

Background: Understanding markers and mechanisms of relapse among patients with recovered dilated cardiomyopathy (DCM) may enable personalized management.

Methods: The relationship between serial heart rate measurements and relapse was examined among patients in the TRED-HF trial, a randomized trial which examined the safety and feasibility of withdrawing heart failure therapy from 51 patients with recovered DCM over 6 months.

Cardiac tamponade from anticoagulant-related spontaneous haemopericardium in a patient with ischaemic cardiomyopathy and heart failure.

We describe the case of an 86-year-old man with a background of severe left ventricular dysfunction and ischaemic cardiomyopathy who, having been optimised for heart failure therapy in hospital, unexpectedly deteriorated again with hypotension and progressive renal failure over the course of 2 days. Common causes of decompensation were ruled out and a bedside echocardiogram unexpectedly diagnosed new pericardial effusion with tamponade physiology. The patient underwent urgent pericardiocentesis and 890 mL of haemorrhagic fluid was drained.

Correlation Between Echocardiographic and Hemodynamic Variables in Cardiothoracic Intensive Care Unit.

Objectives: The echocardiographic indices have not been validated in critically ill population. The authors investigated the correlation between some echocardiographic and hemodynamic parameters.

Design: Prospective, spontaneous, noninterventional observational study.

Relationship between heart rate and outcomes in patients in sinus rhythm or atrial fibrillation with heart failure and reduced ejection fraction.

Aims: To investigate the relationship between heart rate and outcomes in heart failure and reduced ejection fraction (HFrEF) patients in sinus rhythm (SR) and atrial fibrillation (AF) adjusting for natriuretic peptide concentration, a powerful prognosticator.

Methods And Results: Of 13 562 patients from two large HFrEF trials, 10 113 (74.6%) were in SR and 3449 (25.

Impact on survival of combination inhalers in patients with COPD at high risk of cardiovascular events.

Background: Chronic obstructive pulmonary disease (COPD) and cardiovascular disease often co-exist and are both leading causes of death worldwide. Published data have previously suggested trends toward improved survival for patients taking long-acting β agonists combined with inhaled corticosteroids (LABA-ICS) through beneficial actions on the respiratory and cardiovascular systems. We sought to explore this in a real-world setting.

Cardiac structure and function in patients with schizophrenia taking antipsychotic drugs: an MRI study.

Cardiovascular disease (CVD) is a major cause of excess mortality in schizophrenia. Preclinical evidence shows antipsychotics can cause myocardial fibrosis and myocardial inflammation in murine models, but it is not known if this is the case in patients. We therefore set out to determine if there is evidence of cardiac fibrosis and/or inflammation using cardiac MRI in medicated patients with schizophrenia compared with matched healthy controls.

Management of Sleep Apnea in Heart Failure.

Sleep-disordered breathing (SDB) is highly prevalent in heart failure (HF). The presence of SDB in patients with HF appears to be associated with increased risk of cardiovascular morbidity and mortality. In this article, we describe the types, pathophysiology, and consequences of SDB and discuss ways in which SDB can be diagnosed.

Can we remove scar and fibrosis from adult human myocardium?

The pathological processes leading to heart failure are characterized by the formation of fibrosis and scar, yet the dynamics of scar production and removal are incompletely understood. Spontaneous disappearance of myocardial collagen is reported in infancy but doubted in adulthood where scar volume constitutes a better prognostic indicator than the conventional parameters of ventricular function. Whilst certain drugs are known to attenuate myocardial fibrosis evidence is emerging that stem cell therapy also has the potential to reduce scar size and improve myocardial viability.

Immunomodulatory interventions in myocardial infarction and heart failure: a systematic review of clinical trials and meta-analysis of IL-1 inhibition.

Following a myocardial infarction (MI), the immune system helps to repair ischaemic damage and restore tissue integrity, but excessive inflammation has been implicated in adverse cardiac remodelling and development towards heart failure (HF). Pre-clinical studies suggest that timely resolution of inflammation may help prevent HF development and progression. Therapeutic attempts to prevent excessive post-MI inflammation in patients have included pharmacological interventions ranging from broad immunosuppression to immunomodulatory approaches targeting specific cell types or factors with the aim to maintain beneficial aspects of the early post-MI immune response.

Global longitudinal strain corrected by RR-interval is a superior echocardiographic predictor of outcome in patients with atrial fibrillation.

Background: Echocardiographic assessment of systolic and diastolic function during atrial fibrillation (AF) is challenging. This study evaluates the prognostic value of strain in patients with AF and suggests a novel approach on how to take into account the varying heart cycle lengths in AF.

Methods: Echocardiograms from 204 patients with AF during examination were analyzed offline.
