In a month-long study using pigs with brady-arrhythmia, the pacemaker demonstrated sustained energy regeneration and reliable therapeutic pacing without external power sources.

The researchers found that carotid plaque volume derived using the hemi-ellipsoid approach provided a more sensitive tool for evaluating plaque severity and monitoring progression over time compared with diameter or area stenosis alone.

In patients with non-obstructive coronary artery disease, use of IMRCT reduced CMD underdiagnosis rates from approximately 35–39% to below 6%.

Across medium- and long-term follow-up, no patients developed valve stenosis or severe pulmonary regurgitation.

Adaptive ECG noise filtering preserved QT and QRS intervals better than conventional approaches by tailoring filters to noise presence and type.

Impaired heart rate recovery is a powerful new marker for predicting periprocedural myocardial infarction in elective PCI patients.

Global and genetic analyses link low physical activity to rising heart disease mortality, while higher activity levels appear to reduce myocardial infarction risk.

Left atrial appendage closure causes a short-term rise in atrial pressure, but no adverse changes in heart structure or biomarkers were seen during follow-up.
