  • Medicare claims linkage

Authors' conclusion

Among Medicare beneficiaries, CardioMEMS-guided management was associated with a reduction in PAD. Achieving acceptable PAD within 90 days of implant was associated with better survival.

  • Mortality by 90-day PAD trajectory (cohort B): 63.3% elevated at baseline in cohort B; percentages are of those

Predictors of improved PAD

Lower baseline PAD and no history of COPD or atrial arrhythmia associated with higher odds of improved PAD
