Background: Coronary assessment is frequently conducted in patients with sustained monomorphic ventricular tachycardia (SMVT); however, its yield and subsequent treatment implications remain unclear. This study aimed to determine the prevalence of coronary artery disease (CAD) in patients presenting with SMVT, factors influencing clinician referral for coronary assessment, and clinical outcomes based on revascularisation or medical management of CAD.

Method: Consecutive patients presenting with acute SMVT requiring inpatient admission between 2017 and 2022 were identified.

Recent scholarship on carceral mobilities critiques conceptualizations of carceral spaces as fixed and stable, and movements within or around sites of confinement as linear and horizontal. According to this critique, criminological studies of imprisonment have typically embraced what Turner and Peters (2017) ['Rethinking mobility in criminology', 19(1), 96-114] term a 'sedentarist ontology' by failing to consider the complexities of prisoner mobilities in the lived experiences of the carceral. We draw on qualitative interview data from the Prison Transparency Project, a multiyear study initially across four research sites in Canada focused on former prisoners' narratives of their carceral experiences, to identify and analyze the multifaceted mobilities that characterize prison life.

Objective: To examine the feasibility of implementing remote atrial fibrillation (AF) self-screening among older people supported by a remote central monitoring system.

Design: Process evaluation of the Mass AF randomised clinical trial (ACTRN12621000184875) with one-to-one semistructured interviews using interview guides underpinned by the Critical Realism approach and coded using the UK Medical Research Council Guidance of Process Evaluation Framework.

Setting And Participants: Community-dwelling people aged ≥75 years from both genders (ratio 1:1) and urban/rural (ratio 2:1) in Australia.

Aims: Diagnosis of atrial fibrillation (AF) provides opportunities to reduce stroke risk. This study aimed to compare AF diagnosis rates, participant satisfaction, and feasibility of an electrocardiogram (ECG) self-screening virtual care system with usual care.

Methods And Results: This randomized controlled implementation study involving community-dwelling people aged ≥75 years was conducted from May 2021 to June 2023.

Article Synopsis
  • - Preclinical studies show that human pluripotent stem cell-derived cardiomyocytes (PSC-CMs) can help repair injured hearts, with multiple clinical trials underway.
  • - Ventricular arrhythmias (EAs) can occur after injecting PSC-CMs into the heart, linked to cellular diversity within the transplanted cells, particularly arrhythmogenic subpopulations like atrial and pacemaker-like cardiomyocytes.
  • - Identifying specific surface markers may help differentiate risky PSC-CMs from safer ones, and both drug treatments and other interventions can help manage or eliminate these arrhythmias in the experimental model used.
