Clinical Trial Summary

The investigators will determine the feasibility of identifying and quantifying changes in interstitial and intravascular congestion by imaging in participants with heart failure. The investigators will either continue or temporarily suspend both loop diuretics and mineralo-corticoid antagonists (MRA) for 48 hours in participants with heart failure that is both stable and mild and compare measurements of interstitial (B-lines) and intra-vascular fluids (IVC and JV diameter and renal venous flow) by ultrasound and, in a subset of participants without contra-indications, by cardiac MRI.

Eligibility

Inclusion Criteria:

Type	Measure	Description	Time frame	Safety issue
Primary	Differences in ultrasound markers or congestion following continuation or suspension of diuretics for 48 hours.	Differences in interstitial (B-lines) and intravascular (IVC and JV diameter, and renal venous flow) congestion by ultrasound in patients with heart failure following continuation or suspension of diuretics for 48 hours.	at baseline
Secondary	The acute variation in interstitial and intravascular congestion on imaging tests following administration of diuretics.	The acute variation in interstitial (B-lines) and intravascular (inferior vena cava, jugular vein diameter and renal venous flow) congestion on imaging tests following administration of diuretics.	up to 3 hours
Secondary	The acute variation in biomarkers of congestion, inflammation and myocardial injury following administration of diuretics.	The acute variation in biomarkers of congestion (NT-proBNP), inflammation (HsCRP) and myocardial injury (Troponin) following administration of diuretics.	at 3 hours
