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. In this Review, Mathieu and colleagues summarize the risk factors, genetics and molecular mechanisms involved in CAVD and the implications for treatment of the condition.

Aldehyde dehydrogenase 2 (ALDH2), a key enzyme for the detoxification of alcohol-derived acetaldehyde, has been implicated in the pathogenesis of various types of cardiovascular disease. In this Review, Xu and colleagues present the latest evidence showing a link between the inactivating ALDH2 rs671 polymorphism and an increased or decreased risk of cardiovascular disease such as coronary artery disease.
