The first European Society of Cardiology (ESC) guidelines on the management of cardiomyopathies (CMPs), published 1 year ago, remain highly relevant. These guidelines provide a comprehensive framework to manage the complexity of CMPs, consolidating previous approaches. All CMPs are now addressed systematically in one document. The ESC recommends a 'CMP-oriented' approach, emphasizing thorough clinical assessments and phenotype-first categorization into hypertrophic, dilated, arrhythmogenic, restrictive, and non-dilated left ventricular CMP. Despite the utility of this method, certain classifications, such as arrhythmogenic right ventricular CMP and the novel non-dilated left ventricular CMP, raise controversies. Key advances in the guidelines include the use of genetic testing and cardiac magnetic resonance imaging to refine diagnoses and inform treatment, especially for high-risk genotypes. These guidelines advocate for personalized, multidisciplinary care. Overall, they represent a significant step forward but highlight the evolving nature of CMP management as scientific understanding progresses.

Background: Genetic variants in cardiomyopathy genes are associated with risk of atrial fibrillation (AF), although data on clinical outcomes for AF patients with such variants remain sparse.
Objectives: We aimed to study the prognostic implication of rare cardiomyopathy-associated pathogenic variants (CMP-PLP) in AF patients from large, well-phenotyped clinical trials.
Methods: CMP-PLP carriers were identified using exome sequencing in 5 multinational trials from the Thrombolysis in Myocardial Infarction study group (ENGAGE AF, FOURIER, SAVOR, PEGASUS, and DECLARE), with replication in the EAST-AFNET-4 trial.

Background: Cardiomyopathy (CMP) is the leading cause of death in Duchenne muscular dystrophy (DMD). Characterization of disease trajectory can be challenging, especially in early stages of CMP where onset and progression may vary. Traditional metrics from cardiovascular magnetic resonance (CMR) imaging such as LVEF (left ventricular ejection fraction) and LGE (late gadolinium enhancement) are often insufficient for assessing the pace of disease progression.

Pediatric cardiomyopathy (CMP), with an incidence of approximately 1 in 100,000 children, remains a critical clinical challenge. Often progressive, these myocardial disorders frequently culminate in end-stage heart failure, establishing CMP as the primary indication for pediatric heart transplantation. Key considerations for transplantation include specific CMP etiologies and subtypes alongside established listing criteria and strategies to navigate waitlist complexities.

Aims: Premature ventricular contractions (PVCs) in paediatric patients often present a benign course. However, a minority of patients may develop left ventricular (LV) dysfunction, and risk factors are still under debate. The aim of this systematic review and meta-analysis was to analyse the prevalence of PVC-induced cardiomyopathy (CMP) and understand the risk factors in paediatric patients with PVCs and structurally normal hearts.

Background: Chronic inflammatory cardiomyopathy (infl-CMP) is a long-term sequela caused by the chronicity of acute myocarditis, especially fulminant myocarditis (FM). Hydroxychloroquine (HCQ) may benefit these patients by inhibiting the excessive inflammatory response.
Methods: In this multicenter, randomized trial, we evaluated the efficacy and safety of HCQ in patients with chronic infl-CMP after FM.
