Key result
New-onset perioperative atrial fibrillation in elderly patients undergoing hip or knee arthroplasty was associated with higher 1-year all-cause mortality compared to no AF (10.8% vs 1.1%; p=0.005).
Why the study?
Total hip and knee arthroplasties are common in elderly patients, but limited data address the clinical significance of perioperative AF in this population.
Is new-onset perioperative atrial fibrillation associated with increased 1-year all-cause mortality in elderly patients undergoing total knee and hip replacements?
Case-Control (n=560)
Is new-onset perioperative atrial fibrillation associated with increased 1-year all-cause mortality in elderly patients undergoing total knee and hip replacements?
Absolute Event Rate: 10.8% vs 1.1%
p-value: p=0.005
New-onset perioperative atrial fibrillation in elderly patients undergoing total hip or knee arthroplasty is associated with a significantly increased risk of 1-year all-cause mortality, warranting increased clinical surveillance.
No takes yet. Share an insight, caveat, or question.
New-onset perioperative AF was associated with higher 1-year mortality after arthroplasty; leaves open whether targeted interventions improve survival.
Varon et al. (2021) conducted a case-control in Osteoarthritis requiring total hip or knee arthroplasty (n=560). New-onset perioperative atrial fibrillation vs. No atrial fibrillation or previous atrial fibrillation was evaluated on 1-year all-cause mortality (p=0.005). New-onset perioperative atrial fibrillation in elderly patients undergoing hip or knee arthroplasty was associated with higher 1-year all-cause mortality compared to no AF (10.8% vs 1.1%; p=0.005).
