Aneurysm articles from across Nature Portfolio

The growth of aortic aneurysms can be predicted via a dimensionless physiomarker, derived from first principles and calculated from data acquired via 4D flow magnetic resonance imaging, that describes a transition from stable blood flow to unstable aortic fluttering.

Biological sex is increasingly being recognized as an important variable in cardiovascular health and disease and, consequently, in cardiovascular research. Three new studies highlight the influence of sex hormones in pulmonary arterial hypertension, arterial senescence and abdominal aortic aneurysms.

New findings in 2017 enhanced our understanding of the mechanisms that regulate blood pressure. Key studies provided insights into immune mechanisms, the role of the gut microbiota, the adverse effects of perivascular fat and inflammation on the vasculature, and the contribution of rare variants in renin–angiotensin–aldosterone system genes to salt sensitivity.
