Article Synopsis
  • The study aims to use machine learning clustering to categorize distinct patient types among those with ischaemic heart failure and reduced ejection fraction (HFrEF) to improve personalized treatment approaches.
  • Analysis of 8,591 HFrEF patients revealed five unique clusters based on clinical and biological traits, with varying risks for hospitalization and death, highlighting the need for tailored management strategies.
  • The findings indicate that specific clusters correlate with different outcomes, suggesting that treatments like mineralocorticoid receptor antagonists may be more beneficial for certain patient groups, ultimately enhancing patient care in the future.

Background: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease. The relationship between Lp(a) and major adverse cardiovascular events (MACE) in the context of high-sensitivity C-reactive protein (hs-CRP) levels remains controversial due to conflicting results from previous studies.

Objectives: This systematic review and meta-analysis aimed to clarify the association between Lp(a) and risk of MACE across different hs-CRP levels in both primary and secondary prevention settings.

Background And Aim: Diabetes has been shown in last decades to be associated with a significantly higher mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI (PPCI). Therefore, the aim of current study was to evaluate the impact of diabetes on times delays, reperfusion and mortality in a contemporary STEMI population undergoing PPCI, including treatment during the COVID pandemic.

Methods And Results: The ISACS-STEMI COVID-19 is a large-scale retrospective multicenter registry involving PPCI centers from Europe, Latin America, South-East Asia and North-Africa, including patients treated from 1st of March until June 30, 2019 and 2020.

Department of Surgery, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 119228, Singapore; Nanomedicine Translational Research Programme, Centre for NanoMedicine, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 117609, Singapore; Cardiovascular Research Institute (CVRI), National University Heart Centre Singapore (NUHCS), Singapore, 117599, Singapore; Department of Physiology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 117593, Singapore. Electronic address:

miR30d has been shown to reverse cardiac hypertrophy. However, effective delivery of miR30d to the heart is challenging. Here, we engineered milk-derived extracellular vesicles (mEVs) by surface functionalization with an ischemic myocardium-targeting peptide (IMTP) and encapsulated miR30d to develop a formulation, the miR30d-mEVs, enabling targeted delivery of miR30d to the injured heart.

Article Synopsis
  • Successful engineering of vascularized tissues requires incorporating blood capillaries and connecting them to host vessels, which involves arranging endothelial cells to create functional networks.
  • The study compares induced pluripotent stem cell-derived endothelial cells (iPSC-ECs) and primary endothelial cells, finding they perform similarly in forming a capillary-like structure in lab tests.
  • Results indicate that activating certain genes can enhance the tubulogenic activity of iPSC-ECs, supporting their potential use in developing vascularized tissues for therapies.

Artificial intelligence and digital tools for design and execution of cardiovascular clinical trials.

Eur Heart J

November 2024

National Heart Centre Singapore, Duke-National University of Singapore, 5 Hospital Drive, 169609, Singapore, Singapore.

Recent advances have given rise to a spectrum of digital health technologies that have the potential to revolutionize the design and conduct of cardiovascular clinical trials. Advances in domain tasks such as automated diagnosis and classification, synthesis of high-volume data and latent data from adjacent modalities, patient discovery, telemedicine, remote monitoring, augmented reality, and in silico modelling have the potential to enhance the efficiency, accuracy, and cost-effectiveness of cardiovascular clinical trials. However, early experience with these tools has also exposed important issues, including regulatory barriers, clinical validation and acceptance, technological literacy, integration with care models, and health equity concerns.

Purpose: Coronary CT angiography (CCTA) is well established for the diagnostic evaluation and prognostication of coronary artery disease (CAD). The growing burden of CAD in Asia and the emergence of novel CT-based risk markers highlight the need for an automated platform that integrates patient data with CCTA findings to provide tailored, accurate cardiovascular risk assessments. This study aims to develop an artificial intelligence (AI)-driven platform for CAD assessment using CCTA in Singapore's multiethnic population.

  • Assessing glomerular filtration rate (GFR) is essential for kidney disease management, but current methods, particularly estimated GFR (eGFR), can have significant errors affecting patient care.
  • Researchers propose using a panel of multiple filtration markers, alongside non-GFR determinants, to enhance the accuracy of these estimates, building on previous findings that cystatin C improves eGFR precision.
  • Initial evaluations indicate that applying techniques like outlier identification and transfer learning can significantly improve eGFR accuracy, even in populations where traditional methods struggle.

Background: Critical care of patients on extracorporeal membrane oxygenation (ECMO) with acute brain injury (ABI) is notable for a lack of high-quality clinical evidence. Here, we offer guidelines for neurological care (neurological monitoring and management) of adults during and after ECMO support.

Methods: These guidelines are based on clinical practice consensus recommendations and scientific statements.

The "invisible ceiling" of bystander CPR in three Asian countries: Descriptive study of national OHCA registry.

Resuscitation

January 2025

Pre-hospital & Emergency Research Centre, Health Services and Systems Research, Duke-NUS Medical School, Singapore, Singapore. Electronic address:

Background: Bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) has increased in Singapore, Japan, and South Korea following the implementation of several public health, bystander-focused interventions, such as dispatcher-assisted CPR and community CPR training. It is unclear whether bystander CPR prevalence will continue on this trajectory over time. This study aimed to investigate the temporal trends of bystander CPR prevalence over a ten-year period in these three Asian countries.
