Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

open access: yes, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]

open access: yes, 2019
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Mitochondrial Adaptation to Mechanical Stress in Cardiac Ageing and Disease

open access: yesAdvanced Science, EarlyView.
Mechanical forces shape the heart's energy factories. This review explores how mitochondria in cardiac cells sense and respond to biomechanical stress, altering their structure, positioning, and metabolism. By linking mechanical cues to mitochondrial adaptation, the article highlights pathways driving heart disease and points to new strategies for ...
