Osteosarcopenia and Mortality in Older Adults Undergoing Transcatheter Aortic Valve Replacement
Primary result · 1-year mortalityResult — go to the resultOdds ratio 3.18 95% CI 1.54–6.57Authors' conclusion
The findings suggest that osteosarcopenia detected using clinical CT scans could be used to identify frail patients with a 3-fold increase in 1-year mortality following TAVR.
