Abstract

Background: Heart failure (HF) is a chronic condition where the heart cannot pump enough blood to adequately oxygenate cells. The CardioMEMS HF device is implanted into the pulmonary artery (PA) allowing practitioners to monitor pressures remotely and prescribe interventions. Objectives: The primary purpose of this project was to determine if CardioMEMS is an effective intervention in the reduction of hospital admissions, emergency department (ED), and clinic visits for HF patients. The secondary purpose was to determine if the quality of life (QOL) and exercise tolerance was improved post-implant. Methods: The author conducted a retrospective chart review by accessing previously compiled data for patients with the CardioMEMS device to evaluate the number of hospital admissions, emergency, and clinic visits pre and post-implant. Patients completed the Minnesota Living with Heart Failure Questionnaire to determine if their QOL improved. Pre and post 6-minute walk test (6MWT) data was reviewed to evaluate exercise tolerance. Results: The CardioMEMS HF device shows potential to decrease acute inpatient care needs and improve QOL for HF patients. Hospital admissions for HF were significantly reduced post implant (p= 0.020). Self-reported QOL scores significantly improved post-CardioMEMS implant (p<0.0001). There was a non-significant trend towards decreased ED (p= 0.292) and clinic visits (p=0.438) post-CardioMEMS implant. Comparison of changes in 6MWT was inconclusive. Conclusion: The CardioMEMS HF device appears to be a valid option to help minimize acute care needs of HF patients while improving QOL for most. More research is needed to determine effectiveness of CardioMEMS device for exercise tolerance.
