However, PVA provides limited information regarding the haemodynamic significance of stenosis. This prospective study aimed to develop a model combining visual diameter stenosis (DS) and quantitative coronary angiography (QCA)-derived parameters to diagnose ischaemic lesions using invasive fractional flow reserve (FFR) with pharmacologically induced maximal hyperaemia as the gold standard.

Association of Lipoprotein(a) With Major Adverse Cardiovascular Events Across hs-CRP: A Systematic Review and Meta-Analysis.

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.

Interactions between antidiabetes medications and heart-brain axis.

Purpose Of Review: The heart - brain axis (HBA) is the physiological interactions between the cardiovascular and nervous systems through autonomic nerves, hormones, and cytokines. Patients diagnosed with diabetes mellitus have an increased risk of the cardiovascular and neurological diseases. However, recent evidence demonstrated that different antidiabetic drugs may delay cognitive impairment and improve cardiovascular outcomes.

Myocardial delivery of miR30d with peptide-functionalized milk-derived extracellular vesicles for targeted treatment of hypertrophic heart failure.

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.

Cohort profile: AI-driven national Platform for CCTA for clinicaL and industriaL applicatiOns (APOLLO).

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.

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

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.
