@TheRealBovski @RejoinP Do you not see the irony in your message.. Because of Brexit its a lot more difficult to move to Europe!

🫀New research just out in @JMCCPlus suggests sildenafil may reduce #AF vulnerability by altering atrial electrophysiology and increasing atrial refractoriness in a large-animal model.

[American Heart Association @American_Heart]

The American Heart Association mourns the passing of the legendary cardiologist Eugene Braunwald, M.D., widely recognized as one of the most influential figures in the history of cardiovascular medicine. Over seven decades, his work reshaped the understanding and treatment of heart disease, leading many to call him the father of modern cardiology.

Braunwald was a lifelong contributor to the American Heart Association, helping advance its research and scientific mission, and was honored with some of the Association’s highest honors for his lasting influence on cardiovascular care and research. His influence extended well beyond his own discoveries, as generations of Association‑supported investigators, clinicians and academic leaders were trained by Braunwald or guided by the clinical trial standards and mentorship models he helped establish.

Very happy that our most recent paper on the role of #ExtracellularVesicles in #Cardiotoxicity has just been published in @JPhysiol .
Congrats to all authors, especially to Gabriella Bachynskyj-Bilas and @mcmullen_calum

Happy Passover.

Right. It’s only fitting to show you the Passover story told by… a COCKNEY.

This cabbie driver in London tells the story using Cockney rhyming slang in parts.

Chag Pesach Sameach.

Very much looking forward to a series of posts about the upcoming @escardio @EWGCCEChair meeting put together by @CEMolina_1 ...

I was fortunate enough to be the first one!

Have been very fortunate to have just been @escardio #ESCSpringSummit as @EWGCCEChair. Some inspiring and interesting talks about the future of CV health and the biggest challenges we face.. a lot to do but also lots of opportunities! #CVHealth #Cardiovascular @OpenUniversity

[European Society of Cardiology @escardio]

🎬 That’s a wrap on #ESCSpringSummit!
Two inspiring days, countless ideas, and one shared mission: stronger cardiovascular health for every community. 💙
Before we close, hear a final message from @ESC_President, Thomas F. Lüscher – a reminder of what we can achieve when we move forward together across nations and specialties.

Diversity is our strength – unity is our power.

[European Society of Cardiology @escardio]

Good news – the deadlines to submit your abstract and apply for a travel grant for the 50th annual meeting of the ESC Working Group on Cardiac Cellular Electrophysiology (EWGCCE) have been extended to 9 March!

Join us in Leuven, Belgium, from 6-8 July to share your research on the big stage – 20 oral slots, poster opportunities, and awards for the best posters await https://t.co/w7f6h9zied

Nice work just out in @JMCCPlus! Congratulations to the Authors...

Stuck between a ROCK2 and a hard place?
New research just out shows selective ROCK2 inhibition reduces microvascular obstruction after myocardial I/R but doesn’t limit infarct size. Highlights distinct roles for ROCK isoforms in #cardioprotection. 🫀🔬

🫀New research demonstrates that high-throughput, label-free optical oxygen measurements can assess adrenergic effects in iPSC-derived #cardiomyocytes.

Paired with all-optical #electrophysiology, this enables scalable, human-based preclinical testing.

Interesting new work just out in @JMCCPlus !

🫀🦠 How does #COVID19 damage the heart?

New research from Gross et al. using human iPSC-derived #cardiomyocytes uncovers cellular responses to SARS-CoV-2, shedding light on mechanisms of cardiac injury.

Christmas isn't the same for everyone. Saw this on Facebook...so good.

💓 New research from Achlaug et al. @TechnionLive reveals how cancer-driven cytokine signalling improves cardiac function and reduces fibrosis.

Tumour–heart crosstalk with major therapeutic implications

@MollyOReillyy @JPhysiol Sorry, my neurons were obviously not engaged! You are welcome to remake the figure! ;-)

[Dan Johnson @danmjohnson]

Call for papers still open!
Are you working on #cellular #cross-talk in the #heart? Looking for an outlet for your work?

Look no further! @MollyOReillyy, Chris 'O Shea and I are editing an edition of @JPhysiol
Deadline 6th Jan!
