Do you routinely measure #MAPSE?

Did you know that MAPSE beats #GLS and #LVEF regarding prognosis?

Welcome over to see my post on "Choosing your journal" (and avoiding predatory journals).

This is worth a trip to blue sky for. Martin Ugander is brilliant and his calculations are highly relevant and very interesting!

They strengthen the case for our study conclusions and I’m glad to get to see the work from a different, clever angle.

[Predatory Journals @PredatoryReport]

Finland's Publication Forum (or JUFO @tsv_media) announced that from January 2025 it was downgrading its classification of 271 open access journals to the lowest level, zero (this includes 187 journals from @MDPIOpenAccess and 82 from @FrontiersIn).

@ProfDFrancis @rajkumar_chris @drjohnm @rallamee @bnallamo Thanks Darrel. It doesn't look like subtraction anxiety was at work. Rather, "TAVR within the first 6 months" was one of the endpoints. That seems to explain the drastic change in slope - and the entire 'positivity' of the trial(!)

[Martin Ugander @mugander]

@rajkumar_chris @drjohnm Perhaps not subtraction anxiety. Apparently TAVR within 6 months of randomization was a pre-defined 'unplanned CV hospitalization', which convincingly explains the inflection point at 6 months.

Great work on #ECV #WhyCMR in mod or severe asymp #AS

led by HJ Lee & SP Lee w @bernhard_gerber, Gerry McCann, Marc Dweck, @PPibarot

✅ ECV did not assoc with AS severity
✅ ECV independently assoc w outcomes

➡️ AS is about myocardium, not just the valve!

[Andreas Rück @AndreasRck2]

@DFCapodanno The study result was almost entirely driven by TAVR within 6 mo in the conservative arm, which was included as unplanned hospitalization (!). That's why the curves look so strange with the inflection point at 6 mo. Not sure this is enough to tilt the guidelines.

[Martin Ugander @mugander]

@rajkumar_chris @drjohnm @ProfDFrancis @rallamee @bnallamo Thanks @rajkumar_chris for chiming in.

For us new to the concept of subtraction anxiety:

Is the suspiciously pointy corner (immediate change in slope) of the panel A&D yellow curve just before 0.5yr a finding that is pathognomonic for subtraction anxiety?

@tdbauch @AlbertoCereda1 Yes, in this was about normal physiology. Diagnostic performance in disease(s) is obviously a separate question.
