Why the study?
Does dopamine infusion improve systemic and renal hemodynamics in patients with acutely decompensated congestive heart failure, and is this influenced by clinical severity?
Population
18 patients consecutively admitted for acutely decompensated congestive heart failure.
Comparison
Dopamine infusion at 2, 4, and 6 microg/kg/min… vs Saline infusion (in 2 control patients).
Design
Cohort
Follow-up
100 minutes (five 20-min periods)

May support severity-tailored dopamine dosing for renal hemodynamics in decompensated HF; leaves open outcome impact and needs RCTs.
Does dopamine infusion improve systemic and renal hemodynamics in patients with acutely decompensated congestive heart failure, and is this influenced by clinical severity?
The dose of dopamine producing optimal systemic and renal hemodynamic improvement in congestive heart failure is higher than usually reported, and greater clinical severity impairs its renal effects.
Ungar et al. (2004) studied this question.
