www.jacc.org/doi/abs/10.1... I think the take home message here is "give more diuretics" but good to recap the different modalities, and I wonder if I under use tolvaptan?

Learning is contextual. Think about this when wondering how you teach the next generation of clinicians…
Children who learn maths working in markets and children who learn maths only from school were both unable to transfer their skills to new contexts, highlighting a need to reconsider how maths is taught in school, according to a paper in Nature. https://go.nature.com/4aXHcuu 🧪

In mice, Cannabidiol prevented heart failure via various linked means (preserved contractility, preserved calcium dynamics, preserved mitochondrial function), apparently facilitated by PPAR-gamma receptor www.jacc.org/doi/10.1016/...

We're slowly unpicking immune mechanisms of heart failure. A remarkable finding here that patients with higher levels of chemokine-receptor-type-5 expression on circulating lymphocytes were less likely to respond to cardiac resynchronisation therapy www.jacc.org/doi/10.1016/...

Anyone have any advice? Like a lot of cardiology trainees I have accumulated a breadth of skills and interests and can’t decide between them for the rest of my career. How have others managed this?

Slightly interesting - myocyte calcium overload is responsible for arrhythmogenesis and declining cardiac function basically across cardiac diseases - these data links an insulin signalling pathway to this state

Lots to think about in new directions for cardiomyopathy. In particular, how can we test better, and how can we personalise treatment for cardiomyopathies?
