The Hemodynamic Response to Prolonged Dobutamine Infusion
NCT01042873 · Status: UNKNOWN · Phase: PHASE4 · Type: INTERVENTIONAL · Enrollment: 100
Last updated 2018-06-12
Summary
A decrease in the response of beta 1 adrenergic receptors to agonists (desensitization) is thought to play a major role in the pathogenesis of diseases such as congestive heart failure. However, currently, there is no in vivo model that will enable us to measure desensitization of the hemodynamic responses to beta 1 adrenergic receptors in vivo.
Our hypothesis is that constant 3 hours intravenous infusion of the selective beta1 adrenergic receptor agonist dobutamine will result in gradual decline in hemodynamic responses to dobutamine over time.
Conditions
- Healthy
- Heart Failure
Interventions
- DRUG
-
3 hours intravenous dobutamine
Intravenous dobutamine will be infused during 3 hours. At the first and last 0.5 hors of infusion dose will be increased gradually, while in the middle 2 hours dose will remain constant.
