Abstract 17319: Management of Advanced Heart Failure Patients With the Combined Use of CardioMEMS™ and Telehealth: A Single Center Experience in a Veteran’s Affairs Population

Abstract

Background: Due to the Coronavirus Disease of 2019 pandemic many clinics began to utilize virtual visits in lieu of traditional office visits. It is unclear what effect this will have on outcomes and admission rates for heart failure (HF). We describe our approach and outcomes in managing HF in a Veteran’s Affairs population with previously implanted CardioMEMS™ during this time. Methods: Starting February 15 th 2020, virtual visits were utilized in patients with CardioMEMS™ during which their symptoms were discussed and medications adjusted. Patients also received weekly phone calls to ensure that they had medications and to adjust diuretics based on pulmonary artery (PA) pressure readings. They received text message reminders if a reading was missed. A nurse was also tasked to follow up on lab results. Data was collected by reviewing the charts of CardioMEMS™ patients followed in our clinic by cardiology fellows and divided into pre pandemic period of July 1 st 2018 to February 14 th 2020 and a post pandemic period of February 15 th 2020 to May 15 th 2020. Data collected included baseline demographics, number of in-office and virtual visits, hospital admissions for HF, PA pressures, and compliance with CardioMEMS™ readings. Phone calls to adjust diuretics or review labs were not counted as virtual visits. Results: In the pre-pandemic period we identified 49 patients with prior CardioMEMS™; baseline demographics are shown in Table 1A. Table 1B shows our results comparing the pre pandemic and post pandemic periods when our telemedicine program was started. Although in the post pandemic period our encounter rate was lower, our virtual program was able to maintain stable PA pressures and a lower overall hospital admission rate. Compliance with CardioMEMS™ also increased though this was not statistically significant. Conclusion: Both CardioMEMS™ and virtual visits may be used effectively to maintain low PA pressures and reduce hospital admissions for in patients with chronic HF.
