A unified European hydrogen infrastructure planning to support the rapid scale-up of hydrogen production.

Hydrogen will become a key player in transitioning toward a net-zero energy system. However, a clear pathway toward a unified European hydrogen infrastructure to support the rapid scale-up of hydrogen production is still under discussion. This study explores plausible pathways using a fully sector-coupled energy system model.

Comparison of the left ventricular electromechanical map before percutaneous coronary stent revascularization and at one-month follow-up in patients with a recent ST elevation infarction.

The study aimed to evaluate the safety and potential of percutaneous transluminal electromechanical mapping (NOGA) in patients with regional myocardial wall dysfunction after a recent ST elevation myocardial infarction (STEMI). Regional myocardial wall dysfunction is a major cause of morbidity in survivors of ST elevation myocardial infarction. Fifteen males who recently had suffered a STEMI were studied prospectively with coronary angiography, ventriculography, and NOGA before and 1 month after percutaneous coronary intervention (PCI).
