Clinical Trial Summary

Heart failure is a major cause of death and hospitalization in Canada. Many of the symptoms experienced by patients with heart failure relate to having fluid accumulate in the lungs causing difficulty breathing, swelling in the legs, and an increase in weight. Thus, one of the cornerstones of managing heart failure includes the use of medications known as diuretics that target the kidneys to reduce fluid accumulation via urination. Deciding on the correct dose of this medication can be quite nuanced as under-dosing can lead to accumulation of fluid, and over-dosing can dehydrate patients and potentially result in lightheadedness/fainting and damage to the kidneys. Currently, options for prescribing diuretics for heart failure include 1) giving patients a regular, fixed dose or 2) having patients monitor their daily weight as a surrogate of their fluid status and then take a dose of diuretic based on a pre-prepared scale. The rationale behind the flexible weight-based diuretic scale is that it can potentially detect early fluid accumulation and thus possibly prevent hospitalization or ED visits, and it also avoids over-dosing and potentially dehydrating patients. Currently, it is not clear whether the flexible diuretic regimen is better than the fixed-dose regimen in preventing ED visits, hospitalizations, kidney damage, or death and as such, this pilot study will directly compare the two commonly used regimens in the management of chronic heart failure patients.
