Two studies presented at AHA 2024 Scientific Sessions describe the efficacy and safety of left atrial appendage closure after catheter ablation for atrial fibrillation and the 5-year outcomes of the largest randomized left atrial appendage closure trial to date comparing the safety and efficacy of two devices.

Population studies have reported that proton-pump inhibitors (PPIs) increase cardiovascular mortality, at least in part owing to an increased propensity for life-threatening arrhythmias, but these findings have largely been ignored. We propose a series of recommendations for prescribers of PPIs to ensure a balance of the benefits against the potential arrhythmic risks.

This call to action aims to increase awareness of inclusive language in medicine to enhance the experiences of patients and staff and improve health outcomes. Recognizing that terms change, we urge all health-care professionals to advocate for their colleagues and patients. This responsibility to educate the community should not fall exclusively onto marginalized communities.

Large language models represent a transformative leap in artificial intelligence and natural language processing, offering exciting potential across cardiology, from clinical care to education and research. However, several crucial challenges limit the practical implementation of large language models in cardiology. Interdisciplinary research is imperative to overcome these barriers.

English has long been the dominant language in scientific communication. Although having a universal language for scientific communication is beneficial, this standard imposes a considerable barrier for researchers who do not speak English fluently. However, the current generation of scientists is overcoming this barrier through the use of artificial intelligence-based language tools.

Debate exists regarding the best terminology for common presentations of heart diseases caused by epicardial and/or microvascular coronary artery disease with or without myocardial ischaemia. In this Comment, we discuss the pros and cons of a new proposal to replace the vessel-based nomenclature of acute and chronic coronary syndromes with the myocardial-oriented nomenclature of acute and non-acute myocardial ischaemic syndromes.
