Morning pulmonary artery pressure measurements by CardioMEMS are most stable and recommended for pressure trends monitoring.

ABSTRACT:

Aims

The CardioMEMS HF system is used to measure pulmonary artery (PA) pressures of patients with heart failure (HF). The goal of this study was to determine the impact of time in the daily PA pressure measurements, considering variance and influence of circadian rhythms on cardiovascular pathophysiology.

Methods and results

The study included 10 patients with HF with reduced ejection fraction (LVEF < 40%; New York Heart Association class III). Individual daily PA pressures were obtained by CardioMEMS sensors, per protocol, measured up to six times throughout the day, for a period of 5 days. Differences between variation of morning versus evening PA pressures were compared with Wilcoxon signed-rank test. Mean PA pressures (mPAP) increased from a morning value of 19.1 ± 2 mm
