Abraham J, et al. - Researchers investigated the association between treatment guided by ambulatory hemodynamic monitoring and clinical outcomes in patients with heart failure. In this matched cohort study of Medicare beneficiaries, they identified 1087 Medicare patients who received implants of a pulmonary artery pressure sensor from the 100% Medicare claims database and matched each patient to a control patient by demographic features, history of HF hospitalization, and number of all-cause hospitalizations. Patients with implantation of a wireless pulmonary artery pressure sensor had a significantly lower rate of heart failure hospitalization at 12 months than a cohort of concurrently treated, propensity-matched control patients. This suggests association of ambulatory hemodynamic monitoring with reduced rates of heart failure hospitalization among patients with chronic heart failure.
