Thank you to the @heartfoundation for their award of a post-doctoral fellowship to support my ongoing research @UniofAdelaide.
As ever, I am grateful to @PrashSanders and @Elliott_AD for their continued mentorship. #CHRD

Kicking off #APHRS2025 with an insightful session on “What is the best treatment for arrhythmias in patients with heart failure?”
Fantastic presentation by CHRD member @JonathanAriya unpacking how AF intersects with HFrEF and HFpEF.

On behalf of senior author @gregorymmarcus and trial team:
Honored to present the late-breaking clinical trial DECAF at #AHA25 today
In contrast to conventional wisdom, coffee ☕️resulted in less AF #afib compared to abstinence!

Does coffee increase AF #afib risk?
Find out at #AHA25 this Sunday where on behalf of @gregorymmarcus and team I’ll be presenting the DECAF trial
The first randomized trial on coffee and AF #afib

Longer AF ablation waiting lists are resulting in poorer ablation outcomes BUT obtaining and maintaining sinus rhythm during the wait time could help. New data from @BlackpoolHosp

Among patients with #AtrialFibrillation, elevated BMI, and 1 or more additional cardiometabolic risk factors, aggressive risk factor management reduced arrhythmia recurrence over the 12-month period after catheter ablation. ja.ma/47ehz8t

🚨 New from #CHRD in JACC EP:
Obesity presents a unique phenotype of HFpEF
In AF patients, obesity & ↑ epicardial adipose tissue drive higher atrial pressures, pericardial restraint & greater prevalence of HFpEF
Targeting weight loss may improve symptoms & reduce HF risk.

Obesity is a major driver of AFib.
Our latest review in @HeartLungCirc explores the pathophysiological links & how lifestyle & pharmacological therapies may help reduce AF burden.

@JonathanAriya shows that many AF ablation patients have subclinical HFpEF — elevated filling pressures, impaired reserve, yet no ‘diagnosis.’
If it’s there and it matters, shouldn’t we be treating HFpEF while we ablate? 🔥❤️🩹 #AFib #HFpEF #CSANZ2025

HFpEF AFib = a toxic duo. @JonathanAriya work shows AF isn’t just a bystander — it worsens haemodynamics, drives symptoms, and fuels hospitalisations.
If AF is part of the problem, shouldn’t ablation be part of the solution? 🔥❤️🩹 #AFib #HFpEF

🚨 New study out now!
Can your pacing lead handle a hypertrophied septum? We developed an ex-vivo ovine model to test Stylet Driven vs Lumen Less Leads in thick septa.
🧠 SDLs went deeper, faster, and with less torque.
