@DrPMDavidson Thank you @DrPMDavidson . Such an honour personally but also for all the patients who were represented in this research. ❤️

[Marie-Claire Seeley @mcseeley]

I’m so honoured. Sincere thanks to @CSANZCNC and my awesome supervisors. @sahmriAU @UniofAdelaide

[Caleb Ferguson @calebferg]

Massive congratulations to Dr @mcseeley on award of the 2025 @thecsanz @CSANZCNC Cardiovascular Nursing Prize.
For research on POTS registry.
Congratulations on such impactful work - kudos! ❤️ #csanz2025

New 🇦🇺 data from our POTS registry: teens & adults experience POTS differently.
- Teens: worse orthostatic symptoms
- Adults: more gut & bladder issues
Both report = poor QoL.
Proud to author this work.

🚨 New research supported by @AustralianPots published @EurJCardNurs: Women with #POTS report worse autonomic symptoms than men, despite equal anxiety & healthcare use.
Yet face longer diagnostic delays.

Proud to share our latest work showing that women with POTS experience worse autonomic symptoms and longer diagnostic delays — despite similar anxiety and health-seeking behaviour as men.
Time to address the clinician-side of the equation.

New from @Stanford_Neuro Among 491 individuals with no prior history of #autonomic disorders:
🔹 44% developed an autonomic disorder after COVID-19
🔹 75% of these had new onset POTS

While working on a new paper, I've been re-reading old papers on #POTS: one is from Dr. Low et al of Mayo Clinic who was one of the first to describe it. Years later we have crazy debates on what POTS is, with one senior researcher recently saying in a meeting that "it's a controversial diagnosis" while some other physicians attempt to lump it with functional neurologic disorders. This paragraph should be re-read by all of us in this field to remind ourselves what POTS really is: a restricted form of autonomic #neuropathy in at least 50% of patients.

Cardiovascular outcomes in long COVID-19: a systematic review and meta-analysis

🔥Meta-analysis including nearly 10 million patients, only confirming what we already know:

➡️Long COVID-19 was associated with a higher risk of
- thromboembolic disorders [HR 3.12 (1.60, 6.08)],
- coronary heart disease [HR 1.61 (1.13, 2.31)],
- stroke [HR 1.71 (1.07,2.72)],
- arrhythmia [HR 1.60 (1.13, 2.26)],
- cardiomyopathy [HR 1.71 (1.12, 2.61)],
- myocarditis [HR 6.11 (4.17,8.94)],
- hypertension [HR 1.70 (1.56, 1.85)],
- heart failure [HR 1.72 (1.15,2.59)]
- and cardiogenic shock [HR 2.09 (1.53,2.86)] compared to non-COVID-19 controls.

➡️The risk of cardiovascular disease increased significantly four weeks or more after recovering from acute COVID-19

➡️This meta-analysis showed that the cardiovascular risk burden of long-term COVID-19 is significant and spans multiple categories of cardiovascular disease (ischemic and non-ischemic heart disease, arrhythmias, etc.).

➡️Care for survivors of COVID-19 after acute attack should include attention to cardiovascular health and disease.

🤔Caution, study has some well noted limitations and only covers ONE C19 infection!

@HarrySpoelstra @sahmriAU @CelineGallaghe2 @DH_Lau @ADARC_UoA Thanks for sharing and continuing to bring attention to science that fights the archaic narrative that post viral syndromes are purely psychosomatic. 🙏

[Marie-Claire Seeley @mcseeley]

Thrilled to share our published study on cerebral hypoperfusion in #POTS! Findings highlight key implications for clinical management and future research into autonomic disorders.

Novel brain SPECT imaging unravels abnormal cerebral perfusion in patients with postural orthostatic tachycardia syndrome and cognitive dysfunction

🔥Elegant and interesting Australian study on POTS/Cognitive dysfunction(56 patients). #LC

➡️Moderate to severe autonomic dysfunction in 75%

➡️Abnormal cerebral blood flow (CBF) was seen in 61%

➡️There is a high prevalence of reduced cerebral perfusion in those with POTS, which is detectable with supine brain SPECT imaging and is associated with diminished quality of life.

➡️The most frequently affected areas are prefrontal lateral and sensorimotor cortices.🤔🤔🤔

➡️Reduced cerebral perfusion appears to be more prevalent in those with comorbid joint hypermobility syndrome and independent of POTS triggers.

➡️These results highlight the need for further research to delineate the etiology and mechanistic pathways underlying neurovascular dysfunction in post-viral and autonomic syndromes including long-COVID.

‼️And again…….its not “between the ears” or FND! Please take this seriously! Don’t let SarsCoV2 https://t.co/rw58iRjUf4 with your brains and Vagal nerve!

Love this from ⁦@CrabbBrendan⁩ ⁦@MJLScoullar⁩ https://t.co/AJHT6Ei2rw. “increased awareness of the biomedical basis of #longCOVID should prompt clinicians to take patients more seriously.” https://t.co/5toczM9cnF
