Daily home monitoring of potassium, creatinine, and estimated plasma volume in heart failure post-discharge.

ABSTRACT:

Aims

Congestive status, serum potassium, and renal function are major determinants of outcomes as well as critical elements for adjusting drug therapy in heart failure (HF) patients. This study aimed at describing the daily variations in estimated plasma volume (ePV, a surrogate of congestion computed from haemoglobin and haematocrit), blood potassium, and estimated glomerular filtration rate during 2 months post-hospitalization for decompensated HF with reduced ejection fraction.

Methods and results

The study was conducted in a single tertiary referral centre. Capillary blood samples were drawn by study nurses at home (7-12 am), and haematocrit, blood haemoglobin, creatinine, and potassium were measured using an approved home-based device (ABOTT i-STAT) (ClinicalTrials.gov:
