We present a model-based study of a therapeutical approach to atrial fibrillation based on pacing. After a systematic evaluation of different atrial pacing sites, we selected pacing from the septum area and designed a novel septum pacing protocol for atrial fibrillation termination. We then evaluated the performance of septum pacing in different models of atrial fibrillation and investigated the effect atrial substrate (cellular properties, anisotropy and heterogeneities) on the ability to capture during pacing. This study highlights the need for the development of patient-specific algorithms for atrial therapies.

Previous observational studies have reported inconsistent associations between nut consumption and cardiovascular diseases (CVD). This study aims to identify the causal relationship between different types of nuts consumption and CVD, and to quantify the potential mediating effects of cardiometabolic factors. We utilized Genome-Wide Association Study (GWAS) data to assess the causal effects of nut consumption on CVD using two-sample Mendelian randomization (MR) and a two-step MR analysis.

Experiencing a traumatic event may lead to Posttraumatic Stress Disorder (PTSD), including symptoms such as flashbacks and hyperarousal. Individuals suffering from PTSD are at increased risk of cardiovascular disease (CVD), but it is unclear why. This study assesses shared genetic liability and potential causal pathways between PTSD and CVD.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reportedly decreased the new-onset atrial arrhythmias in patients with type-2 diabetes (T2DM) or heart failure (HF). This study examined the impact of SGLT2is on catheter ablation for atrial fibrillation (AF) in HF patients without T2DM.
Methods: Persistent AF (PeAF) and HF (N-terminal prohormone of brain natriuretic peptide, NT-proBNP ≥400 pg/ml) patients without T2DM undergoing catheter ablation were prospectively enrolled (n = 102).

AF is a common arrhythmia in cardiomyopathy, particularly when congestive heart failure is present. The neurohormonal activation in congestive heart failure may trigger fibrotic and other changes in the left atrium and the atrial stretch associated with heart failure may induce further atrial pathology and/ or directly trigger AF (8). By the time that patients with AF develop extensive fibrosis, the arrhythmia has been shown to be associated with a greater difficulty in maintaining sinus rhythm despite attempted ablation procedures.

Passive cardiac monitoring has become synonymous with wearable technologies, necessitating patients to incorporate new devices into their daily routines. While this requirement may not be a burden for many, it is a constraint for individuals with chronic diseases who already have their daily routine. In this study, we introduce an innovative technology that harnesses the front-facing camera of smartphones to capture pulsatile signals discreetly when users engage in other activities on their device.
