www.nature.com/articles/s41... FRESH-UP study. Fluid restriction to 1.5L vs liberal intake in HF. NO difference in QoL over 3 months. NO increase in HF hospitalisation, diuretic doses, BNP or weight. BUT median NYHA II, mean EF 40%, median fruse 40mg.

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…

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/...

www.ahajournals.org/doi/10.1161/... has T1 mapping been as useful as we were hoping for in #whyCMR ? Here is shows an incremental ability to predict heart failure in HCM.

Mitochondrial encoded circular RNAs have a role in signalling, regulating mitochondrial permeability transition pore opening. Interfering with this pathway in this model reduced the release of reactive oxygen species into the cytosol. www.ahajournals.org/doi/10.1161/...

Interesting article - Critical Care Cardiology, its models of care delivery and training structures. www.ahajournals.org/doi/full/10....

www.nature.com/articles/s41... the heart is a metabolic omnivore... some evidence that supplementing ketone into cardiac metabolism leads to it being metabolised and increasing cardiac contractility - a novel approach using carbon-13 labelling technology

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?

www.nejm.org/doi/full/10.... @nejm.org update on HFpEF from Theresa McDonagh incorporating an integrated approach to diagnosis and review of the treatments (check out those hazard ratios!)

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 www.ahajournals.org/doi/full/10....

doi.org/10.1001/jama... great editorial poking holes in our belief in Aspirin. Primary prevention evidence doesn't exist and secondary prevention evidence, as we see here, is very flimsy.

Predicted heart mass is the optimal metric for donor-recipient size matching in heart transplantation. But the maths is tough at 3am. Download our simple Heart Transplant Sizing App for free from the Apple Store. apps.apple.com/gb/app/heart...

www.ahajournals.org/doi/10.1161/... Cytotoxic T Cells Drive Outcome in Inflammatory Dilated Cardiomyopathy I'm not bright enough to be an immunologist but there is an interesting story developing about certain myocarditis being driven by T-cells and zoning in on Th17 cells.

www.nature.com/articles/s41... immune checkpoint inhibitor myocarditis is becomming very well studied - the relationship with T-cells and their outcomes perhaps helps us understand myocarditis and cardiac inflammation.

Lots to think about in new directions for cardiomyopathy. In particular, how can we test better, and how can we personalise treatment for cardiomyopathies? academic.oup.com/eurheartj/ar...
