Here we go again! Want to see if the coronary sinus reducer works in refractory angina? Watch Michael Foley present the results of the ORBITA-COSMIC in the main arena at #ACC this Monday #ORBITA Fiyyaz Ahmed-Jushuf Matthew Shun-Shin Shayna Chotai Christopher Rajkumar Florentina Simader


Amazing to see a brilliant friend and colleague Michael Foley present the #ORBITA-COSMIC trial of the coronary sinus reducer with simultaneous publication in The Lancet Rasha Al-Lamee NHLI Imperial NHS ๐ #ACC2024 thelancet.com/journals/lanceโฆ


Q: Does blinding matter in RCTs of surgical procedures? A: Depends on the endpoint JAMA Surgery We compared placebo-controlled and open-label surgical trials to identify when the placebo effect is most powerful Rasha Al-Lamee Katie Thomas NHLI jamanetwork.com/journals/jamasโฆ


In ORBITA-STAR, angina verification with an ischaemic stimulus powerfully predicted response to PCI. #EuroPCR2024 Perhaps we have been too focused on treatment when the problem always lay in the diagnosis! Published today in #JACC jacc.org/doi/10.1016/j.โฆ Rasha Al-Lamee


Always a privilege to work with incredible statisticians (and cardiologists) Frank Harrell and Matthew Shun-Shin. This time for ORBITA-STAR. NHLI Imperial NHS ๐ JACC Journals

ORBITA-STAR at #EuroPCR is a fascinating & successful study of type of chest pain as a predictor of PCI success. Very difficult to ascertain if angina caused by ischemia is what patients felt. This was a concern of Gruentzig's 40 yrs ago! Christopher Rajkumar Rasha Al-Lamee #AngioHistory

Thanks to JACC Journals and PCRonline ๐ซ for showcasing, and the patients who made ORBITA-STAR possible! Hopefully a step toward more targeted treatment.

Excellent discussion of ORBITA-STAR by Michael Chen Simple findings like those made in this study pave the way to solve a major clinical problem. In stable patients, persistent angina is PCIโs Achillesโ heel TCTMD PCRonline ๐ซ Rasha Al-Lamee

Check out our journal club with OPCI on ORBITA-STAR and the symptom stratified analysis of ORBITA-2 Rasha Al-Lamee Florentina Simader NHLI

Should PCI be an option for first line management of stable angina symptoms? Point and counterpoint in Circ: CQO with final word from Brahmajee Nallamothu and TCTMD ahajournals.org/doi/full/10.11โฆ Rasha Al-Lamee


I think so, what else explains an initial high event rate which then subsides (aortic stenosis doesnโt get better!)? Great if you can manage the first 6 months of subtraction anxiety - event rate then tracks the TAVR arm. Psychology so important in clinical trials. John Mandrola, MD
