Another micro-axial flow pump trial, this time in high-risk PCI—same leap of faith, same outcome. Result? No benefit. If anything, a signal in the wrong direction. We keep expanding “protected PCI” without proof it protects patients—only operators. When doing more starts to look like doing harm, it’s time to pause. #ACC26 nejm.org/doi/full/10.1056/NE…

They did an 8000 patient clinical trial at a cost of just $1.3 million by incorporating the trial into routine clinical practice. #ASH25 Traction trial.
Would have cost >100 times more ordinarily.
We need to completely revamp the clinical trial bureaucracy. meetings-api.hematology.org/…

Observational & lab data show #transdermal #HRT doesn’t increase thrombotic risk. Our study provides reassurance that transdermal #estradiol may be safely used in women with a history of thrombosis. @BrMenopauseSoc @hamoda_h25 @RCObsGyn @isth @ThrombosisUK journals.sagepub.com/doi/10.…

Is this the end of rivaroxaban for acute VTE?
@LanaCastellucci presenting the COBBRA trial - 1st RCT comparing apixaban to riva over 3 months.
56% reduction in bleeding risk with apixaban.
A safer Rx with the same efficacy.
