  • More than 50% of patients with chronic heart failure present with iron deficiency, which is associated with reduced quality of life and worse prognosis. Intravenous iron supplementation therapy has been shown to improve clinical outcomes in these patients.

  • Since the discovery of ferroptosis a decade ago, this iron-dependent form of regulated cell death has been implicated in the pathogenesis of cardiovascular disease. In this Review, Fudi Wang and colleagues discuss the link between the metabolic pathways of iron signalling and ferroptosis in the context of the cardiovascular system and describe the potential of ferroptosis inhibitors in the treatment of cardiovascular disease.

  • High plasma levels of HDL cholesterol have been shown to be associated with a lower risk of cardiovascular disease. However, paradoxically, very high HDL-cholesterol levels are associated with increased mortality in patients with coronary artery disease, according to a new study.

  • Important lessons about human susceptibility to coronary atherosclerosis can be learned from the relative resilience of chimpanzees to coronary artery disease (CAD), despite their higher baseline plasma levels of LDL cholesterol and lipoprotein(a) than in humans. Evolutionary pressure and hyper-reactive T cells might have a role in the unique susceptibility of humans to CAD.

  • Mentorship is a crucial element to success and satisfaction among medical professionals. For a successful relationship, both mentors and mentees must examine their roles and goals. In this Comment article, a mentor–mentee pair discuss the necessary attributes for a productive partnership.

  • The totality of evidence from large-scale, randomized, controlled clinical trials and mechanistic studies in the laboratory has provided six crucial lessons about the emerging role of SGLT2 inhibitors to prevent the onset of heart failure in patients at high risk and slow the progression of heart failure in patients with established disease.

  • In this Review, the authors discuss the roles of non-canonical WNT signalling in cardiovascular disease. They provide an overview of non-canonical WNT signalling, describe its links to the pathogenesis of atherosclerosis, heart failure and arrhythmias, and explore the clinical potential of targeting individual components of non-canonical WNT signalling in cardiovascular disease.

  • The evolution of stent design has reduced the incidence of stent thrombosis, meaning that the duration of dual antiplatelet therapy after percutaneous coronary intervention (PCI) might be shortened. In this Review, the authors describe the current evidence base and ongoing clinical trials into the use of P2Y12 inhibitor monotherapy after PCI.

  • Wearable devices are widely used and have a high level of societal acceptance, opening unimagined and unexploited possibilities in cardiovascular medicine. In this Clinical Outlook, we highlight the disruptive potential of wearables for cardiovascular disease prevention, diagnosis and management, and suggest strategies for quickly and safely translating these lifestyle products into medical devices.

  • The relationship between climate change and health outcomes is complex. In this Review, Rajagopalan and colleagues describe the environmental exposures associated with climate change and provide an overview of the consequences of climate change, including air pollution and extreme temperatures, on cardiovascular health and disease.

  • Transcatheter aortic valve implantation (TAVI) is a breakthrough technology to replace the aortic valve in patients with severe aortic stenosis using simple cardiac catheterization instead of thoracic surgery. Initiated 20 years ago by my colleagues and me, TAVI has been performed in >1.5 million patients globally and has profoundly altered the landscape of cardiovascular medicine.

  • Different Notch ligands have opposing roles in regulating the proliferation and differentiation of vascular smooth muscle cells in the pulmonary vasculature in pulmonary arterial hypertension. Selectively targeting Jagged 1–NOTCH3 signalling might be an effective and safe strategy for the treatment of this condition.
