Usefulness of red cell distribution width to predict mortality in patients undergoing endovascular repair of abdominal aortic aneurysms

Int Angiol. 2021 Sep 13. doi: 10.23736/S0392-9590.21.04725-8. Online ahead of print.ABSTRACTBACKGROUND: Red cell distribution width (RDW) reflecting impaired erythropoyesis, has been associated with poor prognosis and mortality in several conditions. The aim of this study was to determine the relationship between RDW and the 5-year survival after the endovascular repair of abdominal aortic aneurysms (EVAR) and its ability to improve the discriminative power of a survival predictive score.METHODS: Retrospective analysis of 284 patients undergoing EVAR at a single centre. The pattern of relationship between RDW and survival was assessed with penalized smoothing splines. Categorized RDW values were added to a predictive score based in standard preoperative variables, whose improvement in discriminative power was calculated on the basis of changes in the C-statistics and the continuous Net Reclassification Index (c-NRI).RESULTS: The survival rate at 5 years was 66.2% and was independently associated with hemoglobin (HR=0.85,p

Dr. Laura Esserman answers the door of her bright yellow Victorian home in San Francisco’s Ashbury neighborhood with a phone at her ear. She’s wrapping up one of several meetings that day with her research team at University of California, San Francisco, where she heads the Carol Franc Buck Breast Care Center. She motions me in and reseats herself at a makeshift home office desk in her living room, sandwiched between a grand piano and set of enormous windows overlooking her front yard’s flower garden. It’s her remote base of operations when she’s not seeing patients or operating at the hospita...
