Prediction of incident atrial fibrillation in community-based electronic health records: a systematic review with meta-analysis
Conclusions Models externally validated for prediction of incident AF in community-based EHR demonstrate moderate predictive ability and high risk of bias. Novel methods may provide stronger discriminative performance. Systematic review registration PROSPERO CRD42021245093.

Infective endocarditis: old problem, new guidelines and still much to learn
Despite major advances in treating valvular heart disease, the in-hospital mortality (15–20%) and 1-year mortality (~=40%) for infective endocarditis (IE) has not improved even with modern antibiotics and surgical therapy. Further, stroke (17%), embolisation other than stroke (23%), heart failure (HF) (32%) and other complications remain common; therefore, all precautions to help prevent IE should be employed where indicated. In underdeveloped countries, IE is most often associated with rheumatic heart disease. In developed countries, IE is increasingly associated with prosthetic valves and intracardiac devices, with...

Contemporary management of persistent atrial fibrillation
Learning objectives Develop a basic understanding of the underlying mechanisms of atrial fibrillation and classification of the disease. Review the main principles in contemporary management of atrial fibrillation with a focus on persistent atrial fibrillation. Discuss catheter ablation in the context of atrial fibrillation. Introduction Atrial fibrillation (AF) is a multisystemic disorder that is associated with an excess risk of stroke, heart failure and mortality.1 It remains the most common sustained arrhythmia and its significance should not be underestimated. Research focused on unveiling the mechanisms of AF began o...

Proteomics profiling reveals a distinct high-risk molecular subtype of hypertrophic cardiomyopathy
Conclusions Our prospective plasma proteomics study not only exhibited the presence of HCM molecular subtypes but also identified pathobiological mechanisms associated with a distinct high-risk subtype of HCM.
