In this Review, Lucia and colleagues explain why obesity is an evolutionarily novel condition, summarize the epidemiological evidence for its detrimental cardiometabolic consequences, discuss the major mechanisms involved in the association between obesity and the risk of cardiometabolic diseases, and examine the evidence for potential ‘healthy’ phenotypes associated with obesity.

In this Review, Redline and colleagues summarize our understanding of the shared risk factors and causal links between obstructive sleep apnoea (OSA) and cardiovascular disease and emerging knowledge on the heterogeneity of OSA. They also explore the potential role of new biomarkers for cardiovascular risk stratification in patients with OSA.

Understanding how adverse professional life experiences affect the mental well-being of cardiologists is important. An unmet and equally important need is to design and implement strategies to prevent emotional harassment and discrimination at health-care workplaces and to effectively support cardiologists who have been exposed to adverse professional life experiences. These strategies are especially needed for female, younger or divorced cardiologists.

Calcific aortic valve disease (CAVD) is a common disorder characterized by thickening, fibrosis and mineralization of the aortic valve leaflets.
