MD. Cardiology. Often smells like ultrasound gel. Also likes crossfit.

@ParrasJorge2 Last image looks like right parasternal view of a severe aortic stenosis, likely the cause of HFrEF. Nice images.

1,3‐butanediol improves cardiac function in heart failure patients, offering potential for sustained ketosis therapy. #AHAJournals @HalvorOG @GNigopan @K_Hylleberg @OHorsdal @KrisBergHansen @AUHCardio https://t.co/yElwqP5qyG

This was a tough one. 40000 abstracts screened. Limited evidence for the use of calcium for Hyperkalaemia

Thrilled to share our new study published in @_JCBFM (https://t.co/9lsDXXoru3)! We show that targeting Na,K-ATPase-dependent Src kinase activation can prevent 🧠 hypoperfusion and exaggerated NVC in a an awake mouse model of familial hemiplegic #migraine.
Here’s a short 🧵

@ChrStaehr @KrisBergHansen @OHorsdal @GNigopan Tak 😊 og godt nytår til dig og familien!

In HFrEF patients, exogenous ketone body therapy improves cardiac function. But they have a short half life.

Here we show prolonged ketosis and cardiac benefit with 1,3-butanediol in HFrEF patients🫀❤️‍🔥

Happy holidays 🍾

Proud to share our recent publications on the neurohormonal effects of #ketone ester treatment and the cardiovascular effects of the novel ketone compound 1,3-butanediol in #heartfailure

@strain_rate Tak. Og tak for altid spændende og relevante opslag om ekko

@khldtaha Hiatal hernia

@MynephCC Nice images. Can you elaborate on why you you place the sample volume in the RVOT rather than in the PA just distal to the valve? I’d personally prefer the latter, as this is where one can get a reliable diameter for stroke volumen, shunt fraction Qp/Qs, etc.

[Halvor Guldbrandsen @HalvorOG]

@narkoselaegen Spændende!

[Halvor Guldbrandsen @HalvorOG]

@StineFGalili Jo tak. Og dig selv? Er du allerede ved at skulle finde en dato for PhD-forsvar?

[Oskar Hørsdal @OHorsdal]

Increasing #PEEP in AMI-CS unloads the LV without altering cardiac output or cardiac efficiency.

PEEP could be a viable treatment option if titrated optimally during AMI-CS

@boyuk_ferit @EchofirstB @alex1708ander @ACCinTouch @alexsfelixecho In suprasternal view: thrombus in right pulmonary artery.

In A4C: hypoechoic area lateral to left atrium. Mirror artefact? Hiatal hernia?
