Influence of pericardium on ventricular mechanical interdependence in an isolated biventricular working pig heart model.

The pericardium plays an important role in mechanical interactions between the right (RV) and left (LV) ventricles, referred to as ventricular interdependence. However, the exact mechanisms of its supportive role remain unknown. The present study aimed to evaluate specifically ventricular interdependence in a model of isolated biventricular working heart of large mammal, which is in absence of neurohormonal influence or series interactions, and to evaluate the impacts of intact pericardium on this phenomenon.

Monitoring and modulating cardiac bioelectricity: from Einthoven to end-user.

In 2024, we celebrate the 100th anniversary of Willem Einthoven receiving the Nobel Prize for his discovery of the mechanism of the electrocardiogram (ECG). Building on Einthoven's legacy, electrocardiography allows the monitoring of cardiac bioelectricity through solutions to the so-called forward and inverse problems. These solutions link local cardiac electrical signals with the morphology of the ECG, offering a reversible connection between the heart's electrical activity and its representation on the body surface.

Glucagon-like peptide-1 receptor agonist use is associated with reduced risk of out-of-hospital cardiac arrest in women with type 2 diabetes: A nationwide nested case-control study.

Objective: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improve cardiovascular outcomes in patients with type 2 diabetes, but few studies have studied the risk of out-of-hospital cardiac arrest (OHCA). We investigated whether GLP-1 RA use reduce OHCA risk in type 2 diabetes when compared to dipeptidyl peptidase-4 inhibitor (DPP-4i) use.

Methods: We identified all patients having a redeemed prescription of a glucose-lowering drug between 1995 and 2019 and excluded patients with a first-time redeemed prescription consisting of insulin.
