Alternative splicing determines which exons are included in mature RNA and accounts for the majority of transcriptomic diversity. In this Review, Gotthardt and colleagues discuss how alternative splicing is regulated in the heart and how it differs in cardiac development, physiological adaptation and pathological remodelling. They also summarize technological advances in the field and potential applications of splicing data in cardiovascular medicine.

The prevalence of hypertension in China has risen steadily in the past two to three decades. In this Review, Wang and colleagues summarize the latest epidemiological data on hypertension in China, describe the risk factors for hypertension that are relevant to this population, and provide an overview of initiatives aimed at improving awareness, treatment and control of hypertension, especially in the low-resource rural setting.

Macrophages are one of the most active cell types during all stages after myocardial infarction. In this Review, Boisvert and co-workers describe the populations of cardiac macrophage involved in myocardial infarction, their cardioprotective functions and their interactions with other cardiac cell types. The authors also explore potential therapeutic approaches to target macrophage-mediated inflammation in myocardial infarction.

Calcific aortic valve disease and stenosis have a complex pathogenesis, and no therapies are available that can halt or slow their progression. In this Perspective, Narula and colleagues explore a possible relationship between amyloid deposition, calcification and the development of aortic valve stenosis.
