Background
Remote monitoring of pulmonary artery pressure (PAP) using CardioMEMS allows early detection of hemodynamic deterioration in heart failure (HF). Clinical benefit depends on structured follow-up in which specialised HF nurses play a key role. Long-term real-world data on nursing-led interventions remain scarce.
Purpose
To describe the role and impact of nursing-led interventions during long-term remote follow-up of HF patients monitored with CardioMEMS, focusing on clinical stability and prevention of hospital admissions.
Methods
Single-center retrospective observational study including consecutive HF patients who underwent CardioMEMS implantation between June 2019 and March 2025 in a multidisciplinary HF unit. Demographic data, device information, nursing interventions, and related clinical actions were analyzed over follow-up up to six years.
Results
Seventy-five patients were included (mean age 73 ± 8.5 years; median HF duration 56 months; mean LVEF 43.8%). A total of 2,853 nursing interventions were recorded, mainly triggered by PAP changes (64%) and missing transmissions (16,2%). Actions included telephone contacts (50,6%), medication adjustments (31.8%), HF clinic visits (5.3%), and fluid restriction advice (8%) . Most deaths were HF-related.
Conclusion
Nurse-led remote monitoring with CardioMEMS enabled early detection, treatment optimization ,and a reduced need for unplanned hospital care, supporting specialized nursing as a key element of long-term telemonitoring.
