Effectiveness and Safety Profile of Remote Pulmonary Artery Hemodynamic Monitoring in a “Real-World” Veterans Affairs Healthcare System

Published:September 29, 2022DOI:https://doi.org/10.1016/j.amjcard.2022.08.039
      Ambulatory hemodynamic monitoring has demonstrated the ability to reduce heart failure-related hospitalization, regardless of left ventricular ejection fraction; however, real-world data in a Veterans Affairs patient population are limited. The present study retrospectively reviewed 53 patients with New York Heart Association class III heart failure, regardless of left ventricular ejection fraction, implanted with a pulmonary artery pressure sensor (CardioMEMS) at our single Veterans Affairs institution. Heart failure-related hospitalizations were assessed in patients for 6 and 12 months after the implantation of the device and compared with the 6- and 12- month periods before implantation in the same patient cohort. Pulmonary arterial pressures and medication doses were also recorded at baseline, 6- months, and 12- months and procedural safety data were also assessed. Implantation of a remote pulmonary artery pressure sensor was associated with a 52% (95% confidence interval 30% to 68%, p <0.001) and a 44% (95% confidence interval 24% to 59%, p <0.001) reduction in heart failure-related hospitalization at 6 and 12 months after implant, respectively, compared with the 6- and 12-month preimplant periods. Mean pulmonary arterial pressures also demonstrated significant reductions from baseline to 6 and 12 months after implant. A total of 3 procedure-related adverse events were noted. In conclusion, pulmonary artery pressure sensor implantation is relatively safe and associated with significant reductions in heart failure-related hospitalization and decreased mean pulmonary artery pressures in patients within the Veterans Affairs system with New York Heart Association class III symptoms, regardless of ejection fraction.
