Establishment and maintenance of specialized CMs in the heart is critical for the proper cardiac structure and function. Conversely, loss or gain of their identities is associated with various heart diseases such as cardiac arrythmia and cardiomyopathy. CM identity is established during early heart development and continues to be maintained under normal physiological condition, and this is predominantly accomplished by gene regulation. Our understanding of potential genetic, epigenetic or posttranscriptional programs that regulate CM identity (e.g., atrial or ventricular CM identity) is still quite limited. To this end, we summarize current understandings on atrial and ventricular CM identity regulations and discuss potential future research directions to unveil the underlying regulatory mechanisms.

Aims: There is a lack of data from randomized clinical trials comparing treatment outcomes between conduction system pacing (CSP) modalities and biventricular pacing (BVP) in symptomatic patients with refractory atrial fibrillation (AF) scheduled for atrioventricular node ablation (AVNA). The CONDUCT-AF investigates whether CSP is non-inferior to BVP in improving left ventricular ejection fraction (LVEF) and clinical outcomes in heart failure (HF) patients with symptomatic AF undergoing AVNA.
Methods: This study is an investigator-initiated, prospective, randomized, multicentre clinical trial conducted across 10 European centres, enrolling 82 patients with symptomatic AF, HF with reduced LVEF, and narrow QRS.

Objective: Originally designed to evaluate stroke risk in individuals with atrial fibrillation unrelated to valvular disease, the CHA2DS2-VASc score (Congestive heart failure, Hypertension, Age ≥ 75 years, Diabetes mellitus, prior Stroke/transient ischemic attack/systemic embolism, Vascular disease, Age 65-74 years, and Sex category - female) is now additionally utilized for the prognostic evaluation of cardiovascular diseases. This study aimed to evaluate the predictive role of the CHA2DS2-VASc score for lesion severity and long-term survival outcomes in individuals with peripheral artery disease (PAD).
Method: This retrospective analysis included 784 patients diagnosed with PAD via computed tomography (CT) angiography, consecutively enrolled from two medical centers.

Apical hypertrophic cardiomyopathy (ApHCM) is an uncommon, nonobstructive form of hypertrophic cardiomyopathy (HCM) that is associated with an increased risk of ventricular aneurysms, atrial fibrillation, heart failure, and cardiac death. In this case report, a 63-year-old male patient was found to have deeply negative T waves on electrocardiogram (EKG) during a routine preoperative evaluation in an outpatient internal medicine clinic. Imaging with echocardiography and cardiac magnetic resonance confirmed the diagnosis of ApHCM.

Postoperative atrial fibrillation (POAF) is a common complication following anatomic lung resection, contributing to increased morbidity and mortality, prolonged hospital stays, and higher healthcare costs. Despite its frequency, there remains limited consensus on optimal pharmacologic management in this population, particularly in the context of balancing efficacy with the unique risks associated with thoracic surgery. This report aims to draw attention to the clinical significance of POAF in thoracic surgery, particularly following pulmonary resections, by presenting a representative case and contextualizing it through a focused review of current literature and consensus guidelines.

Background: Arterial compliance is an independent predictor of diastolic dysfunction. Invasive catheterization can accurately reflect diastolic function. However, studies on the invasive assessment of diastolic function are currently limited.
