Background: There is limited information on diurnal variation in pulmonary artery pressures (PAP) in ambulatory heart failure (HF) patients. We aimed to study the variation in morning and night-time PAP in HF patients with an implanted CardioMEMS sensor.
Methods: In this prospective, single centre study we enrolled patients who had a cardioMEMS sensor and consented to participate (End stage renal disease and recent hospitalisation for acute HF were exclusions).
CardioMEMS, a remote pulmonary artery pressure monitoring system, provides waveform patterns for the ambulatory heart failure patient. These waveforms provide significant insights into patient volume and clinical management. We aim to provide a foundation for understanding the determinants of waveform characteristics and provide practical examples illustrating how to interpret and integrate common scenario waveforms into clinical decision-making.

Current technological advancements in cardiac implantable electronic devices have allowed the detection of specific physiological parameters that are used to forecast clinical decompensation through algorithmic, multiparameter remote monitoring. Other recent emerging technologies, including cardiac contractility modulation and baroreflex activation therapy, may provide symptomatic or physiological benefits in patients without indications for cardiac resynchronization.
