Such a fascinating topic
Can pacing (and particularly #CSP) cure #HFpEF?

@DanielLustgart4 presenting elegant results from the PACE HFpEF study and the upcoming ELEVATE HFpEF trial

Presenting our latest work on PPM-detected physical activity and the association with cardiopulmonary exercise testing at @ESSA_NEWS Activate. Thanks for the great attendance and discussions!

@YouriBekhuis @HRSonline @Elliott_AD @PrashSanders @melissaemm1 Thank you @YouriBekhuis 🙌🏼

[Jackson Howie @JacksonHowie14]

Fortunate to have 3x posters at @HRSonline:

1. PPM-detected activity correlates with objective exercise tolerance!

2. PPM-detected activity and HFpEF are closely related!

3. The HFpEF scoring systems disagree!

Risk Factors in AF session at the Centre for Heart Rhythm Disorders 20th Anniversary!

Excellent talks from @Elliott_AD, @WongChrisX, @JonathanAriya, and Sam Tu exploring exercise, epicardial fat, heart failure, and alcohol — each contributing to AF risk 🫀

[Jackson Howie @JacksonHowie14]

Celebrating 20 years of the Centre for Heart Rhythm Disorders! 🎉

Congratulations to Professor @PrashSanders and the entire team on two decades of outstanding contributions to AF research and patient care 🫀

New publication from @JonathanAriya and #CHRD!

We found that in patients with AF, obesity and epicardial fat are linked to worse hemodynamics and a higher risk of HFpEF.

These findings highlight the potential role of weight management and HFpEF therapies in this group.

[Prash Sanders @PrashSanders]

🚨 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.

Four year observational followup of myPACE study with great team of UVM➡️Duke (Jamie Cyr, Alexy Novelli) & ➡️UW (Becca Rawlings) residents, @KramerWahlberg @lusty63 @MarkusMeyerMD & others w/o twitter/X. consider liberalizing HR in HFpEF!

[Jackson Howie @JacksonHowie14]

Congratulations @PrashSanders and #CHRD 🎉

[John Mandrola, MD @drjohnm]

A hugely important clinical question 👇🏻

📢 It’s finally out! My first PhD publication has been accepted in Heart Rhythm!

[Jackson Howie @JacksonHowie14]

In symptomatic AF patients, advancing age is associated with:
▪️Advanced LA disease
▪️Exercise intolerance
▪️Elevated biomarkers
▪️But NOT patient symptoms

Great insights from @JonathanAriya about the impact of AF on HFpEF - Heart rhythm Council at #CSANZ25 @thecsanz @PrashSanders @melissaemm1 @JacksonHowie14 @Elliott_AD @davidchieng

After much effort, the 2025 @SACVRN Emerging Leaders Symposium is closed! Thank you to the incredible organising committee who made this possible, and well done to all our presenters. See you in 2026 🎉

Long-Term Risk Assessment in Athletes With Complex Ventricular Arrhythmias (Circulation: EP, 2025)

🔍Key findings:
Common ventricular arrhythmia = low risk
Uncommon ventricular arrhythmia + LGE or inducible VT = higher risk

⚠️ Caveat: events were rare
