Impact of Cardiac Rehabilitation on Reducing Cardiovascular Events and Subsequent Medical Expenses for One Year in Patients with Transcatheter Aortic Valve Implantation

Introduction: It remains unclear whether cardiac rehabilitation (CR) can reduce medical expenses (ME)in patients with Transcatheter Aortic Valve Implantation (TAVI). Hypothesis: Outpatients CR reduced the cardiovascular events (CEs) and the total ME for one year in patients after TAVI. Methods: This retrospective analysis enrolled consecutive 148 patients who admitted TAVI treatment at the Showa University Hospital, between December 2015 and September 2019. Exclusion criteria was in-hospital death, difficulty walking at discharge and patients who could not be followed up after the hospital discharge. The subsequent ME for outpatient clinic and/or rehospitalization due to CEs in avarage 1.5 years after the discharge were compared between the CR group and non-CR group. CEs were defined as death, ACS, angina, stroke, and heart failure. Results: The CR group was significantly reduced the CEs compared with the non-CR group (logrank = 4.538 p = 0.033). (figure1)The CR group was significantly increased the outpatient ME (p < 0.001). However, rehospitalization and total ME were significantly lower in the CR group (p = 0.003, p = 0.002). (figure2) Conclusions: Outpatients CR reduced the CEs and the total ME for one year in patients after TAVI.
