Recognizing patients as candidates for temporary mechanical circulatory support along the spectrum of cardiogenic shock.

A growing body of evidence indicates that the benefits of temporary mechanical circulatory support (tMCS) in patients with cardiogenic shock (CS) is dependent on its aetiology and timing of implantation. As such, appropriate diagnosis, screening, selection, and treatment is crucial to achieving good outcomes with tMCS. Here, the latest guidance on CS phenotypes and diagnostics for correctly identifying tMCS candidates is discussed.

Frequency of extracardiac findings on "negative" CT coronary angiography studies.

Aim: To evaluate the prevalence and nature of extracardiac findings identified on computed tomography (CT) coronary angiography (CTCA) in patients with chest pain but without evidence of coronary artery disease (CAD).

Materials And Methods: CTCA studies in patients referred to the hospital between January 2017 to February 2021 with chest pain and a suspected diagnosis of CAD were reviewed retrospectively for the presence of extracardiac findings. Consensus review of CTCA studies was performed by two experienced thoracic radiologists.

Gene signatures in U-BIOPRED severe asthma for molecular phenotyping and precision medicine: time for clinical use.

Introduction: The use and generation of gene signatures have been established as a method to define molecular endotypes in complex diseases such as severe asthma. Bioinformatic approaches have now been applied to large omics datasets to define the various co-existing inflammatory and cellular functional pathways driving or characterizing a particular molecular endotype.

Areas Covered: Molecular phenotypes and endotypes of Type 2 inflammatory pathways and also of non-Type 2 inflammatory pathways, such as IL-6 trans-signaling, IL-17 activation, and IL-22 activation, have been defined in the Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes dataset.

Non-invasive left ventricular pressure-volume loops from cardiovascular magnetic resonance imaging and brachial blood pressure: validation using pressure catheter measurements.

Aims: Left ventricular (LV) pressure-volume (PV) loops provide gold-standard physiological information but require invasive measurements of ventricular intracavity pressure, limiting clinical and research applications. A non-invasive method for the computation of PV loops from magnetic resonance imaging and brachial cuff blood pressure has recently been proposed. Here we evaluated the fidelity of the non-invasive PV algorithm against invasive LV pressures in humans.

The Impact of Ferric Derisomaltose on Cardiovascular and Noncardiovascular Events in Patients With Anemia, Iron Deficiency, and Heart Failure With Reduced Ejection Fraction.

Background: In some countries, intravenous ferric derisomaltose (FDI) is only licensed for treating iron deficiency with anemia. Accordingly, we investigated the effects of intravenous FDI in a subgroup of patients with anemia in the IRONMAN (Effectiveness of Intravenous (IV) Iron Treatment Versus Standard Care in Patients With Heart Failure and Iron Deficiency) trial.

Method And Results: IRONMAN enrolled patients with heart failure, a left ventricular ejection fraction of ≤45%, and iron deficiency (ferritin <100 µg/L or transferrin saturation of <20%), 771 (68%) of whom had anemia (hemoglobin <12 g/dL for women and <13 g/dL for men).

Adult Severe Asthma Registries: A Global and Growing Inventory.

Aim: The International Severe Asthma Registry (ISAR; http://isaregistries.org/) uses standardised variables to enable multi-country and adequately powered research in severe asthma. This study aims to look at the data countries within ISAR and non-ISAR countries reported collecting that enable global research that support individual country interests.

Electrocardiographic abnormalities in patients with cardiomyopathies.

Abnormalities in impulse generation and transmission are among the first signs of cardiac remodeling in cardiomyopathies. Accordingly, 12-lead electrocardiogram (ECG) of patients with cardiomyopathies may show multiple abnormalities. Some findings are suggestive of specific disorders, such as the discrepancy between QRS voltages and left ventricular (LV) mass for cardiac amyloidosis or the inverted T waves in the right precordial leads for arrhythmogenic cardiomyopathy.

Five-Repetition Sit-to-Stand Test: Responsiveness and Minimal Important Difference in Idiopathic Pulmonary Fibrosis.

Standing from a sitting position is an important activity of daily living. The five-repetition sit-to-stand test (5STS) is a simple physical performance test that measures the fastest time taken to stand five times from a chair with arms folded. It can be measured in most healthcare settings and at home, where traditional field walking tests may not be possible.

Comparison of mid-term mortality after surgical, supported or unsupported percutaneous revascularization in patients with severely reduced ejection fraction: A direct and network meta-analysis of adjusted observational studies and randomized-controlled.

Introduction: The optimal revascularization strategy in patients with heart failure with reduced ejection fraction (HFrEF) remains to be elucidated. The aim of this paper is to compare the mid-term mortality rate among patients with severely reduced ejection fraction (EF) and complex coronary artery disease who underwent coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) with Impella support, or without.

Methods: Randomized control trials and propensity-adjusted observational studies including patients with ischemic cardiomyopathy (ICM) and severe EF reduction undergoing revascularization were selected.

Valvulogenesis of a living, innervated pulmonary root induced by an acellular scaffold.

Heart valve disease is a major cause of mortality and morbidity worldwide with no effective medical therapy and no ideal valve substitute emulating the extremely sophisticated functions of a living heart valve. These functions influence survival and quality of life. This has stimulated extensive attempts at tissue engineering "living" heart valves.

Dual-Antiplatelet Therapy After Coronary Artery Bypass Grafting: A Survey of UK Cardiac Surgeons.

Objective: Antiplatelet therapy after coronary artery bypass grafting (CABG) is important in postoperative medical management. Although cardiac surgeons are well-versed in the guidelines regarding discontinuation of dual-antiplatelet therapy (DAPT; aspirin and a P2Y12 antagonist) before CABG to minimize bleeding risk, there is considerable variability in DAPT dosing after CABG. The objective of this study was to explore the current trends in DAPT after CABG in the UK to improve understanding of the existing practice.

Cross-cultural adaptation of the FRAIL scale for critically ill patients in Spain.

Aim: To translate and culturally adapt the FRAIL scale into Spanish and perform a preliminary test of diagnostic accuracy in patients admitted to intensive care units.

Design: Cross-sectional diagnostic study.

Methods: Five intensive care units (ICU) in Spain were participated.

Phenotype, outcomes and natural history of early-stage non-ischaemic cardiomyopathy.

Aims: To characterize the phenotype, clinical outcomes and rate of disease progression in patients with early-stage non-ischaemic cardiomyopathy (early-NICM).

Methods And Results: We conducted a prospective observational cohort study of patients with early-NICM assessed by late gadolinium enhancement cardiovascular magnetic resonance (CMR). Cases were classified into the following subgroups: isolated left ventricular dilatation (early-NICM H-/D+), non-dilated left ventricular cardiomyopathy (early-NICM H+/D-), or early dilated cardiomyopathy (early-NICM H+/D+).

Antiplatelet Resistance in Patients Who Underwent Coronary Artery Bypass Grafting: A Systematic Review and Meta-Analysis.

Antiplatelet therapy (APT) with aspirin and a P2Y12 inhibitor is commonly given to patients who underwent coronary artery bypass grafting (CABG) to reduce thrombotic events. APT resistance, the inadequate antiplatelet effect of these drugs, is a growing concern. This review aimed to assess APT resistance prevalence in patients who underwent CABG and its impact on clinical outcomes.

Contemporary Considerations in the Evolution of Wearable Technology for Arrhythmia Detection.

Arrhythmias are an increasingly common cause of hospital admissions worldwide. Late detection of arrhythmias is associated with a significantly increased risk of cardiovascular complications. Early identification and management of life-threatening arrhythmias is paramount to reduce mortality.

How We Would Treat Our Own Lung Transplantation: A Multidisciplinary and International Perspective.

Lung transplantation is the ultimate treatment for end-stage lung disease (ESLD) arising from various etiologies. This manuscript will focus on selected aspects of a theoretical perioperative lung transplantation plan, highlighting data-driven and theoretical techniques the authors would employ if they were the index patient undergoing surgery. Beginning with looking for a transplant center using an Internet search, patient advocacy organizations, and artificial intelligence guidance, the authors lay out a course for multidisciplinary care throughout the entire patient journey, ending with ideal approaches to recovery 6 months posttransplantation.

The BE-ALIVE score: assessing 30-day mortality risk in patients presenting with acute coronary syndromes.

Aim: To create and validate a simple scoring system for predicting 30-day mortality in patients presenting with acute coronary syndromes (ACS) at their moment of admission.

Methods And Results: 2407 consecutive patients presenting to Harefield Hospital with measured arterial blood gases, from January 2011 to December 2020, were studied to build the training set. 30-day mortality in this group was 17.

Asymmetry of flow in aortic root and its application in hypertrophic obstructive cardiomyopathy.

The aortic root (AR) performs sophisticated functions regulating the blood dynamics during the cardiac cycle. Such complex function depends on the nature of flow in the AR. Here, we investigate the potential of new quantitative parameters of flow asymmetry that could have clinical implications.
