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/...
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.
Prognostic Value of Myocardial T1 Mapping for Predicting Adverse Events in Hypertrophic Cardiomyopathy | Circulation: Cardiovascular Imaging
BACKGROUND: In patients with hypertrophic cardiomyopathy, the prognostic value of myocardial T1 and extracellular volume fraction for adverse cardiovascular events has not been well defined. METHODS...

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/...
Fast Degradation of MecciRNAs by SUPV3L1/ELAC2 Provides a Novel Opportunity to Tackle Heart Failure With Exogenous MecciRNA | Circulation
BACKGROUND: Circular RNAs derived from both nuclear and mitochondrial genomes are identified in animal cells. Mitochondria-encoded circular RNAs (mecciRNAs) are attracting more attention, and several ...

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?

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....

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.
Immune responses in checkpoint myocarditis across heart, blood and tumour - Nature
The molecular characteristics of myocarditis associated with immune checkpoint inhibitors are described and potential biomarkers of onset and severity are identified.

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...
