🫀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. doi.org/10.1016/j.jmcc… @G_Madders #Electrophysiology #Cardiology #AF #Sildenafil

Final days for registration for the #Copenhagen #HFpEF summit happening in a couple of weeks. Final programme now available hfpef-cph.org Looking forward to seeing you all in Copenhagen and feel free to reach out if you need any further information! @DCAcademyDK

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. newsroom.heart.org/news/american-…

Very happy that our most recent paper on the role of #ExtracellularVesicles in #Cardiotoxicity has just been published in @JPhysiol .

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. Via @JTVChannel on YouTube

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! #CardiacResearch #Electrophysiology

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

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 esc365.escardio.org/event/2035 #EWGCCE26 #Epeeps #basicEP #Electrophysiology #ESCYoung @EWGCCEChair

Abstract submission deadline approaching for the 50th EWGCCE! Join us 6–8 July 2026 in Leuven 🇧🇪 to celebrate 50 years of cardiac cellular electrophysiology. Submit your abstract today (or by 2nd March! 😀) Looking forward to seeing you there! #EWGCCE esc365.escardio.org/event/2035

Nice work just out in @JMCCPlus! Congratulations to the Authors... #CardioX #CardioTwitter @JMCCardiology

🫀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. doi.org/10.1016/j.jmcc…

The #deadline for our special edition of @JPhysiol looking at Crosstalk of cells in the #heart has been extended until March 6th! Feel free to get in touch or check out the call on the website! physoc.onlinelibrary.wiley.com/hub/journal/14… @MollyOReillyy @PhySoc

Interesting new work just out in @JMCCPlus !

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

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

@danmjohnson @JPhysiol Where’s the neuron?! 🤨😉

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! physoc.onlinelibrary.wiley.com/hub/journal/14…

New paper just out in @JMCCPlus ! Congrats to the #Authors and thanks to the #Reviewers
