The Safety and Efficacy of Adjunct Carvedilol in Children With Moderate Heart Failure
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
We would like to see if using Carvedilol in adjunct with Ace inhibitors will increase ejection fraction of the heart under echo. All interpretation of data will be sent to Boston Children's Hospital to be reviewed, which is the primary research center in this study. There are 5 hospitals participating in this study. The population targeted are children with moderate heart failure and must be on Ace inhibitors at the time of enrollment. Our outcome after placing them on Carvedilol is to change their ejection fraction on echo. The patients will be seen every 1-2 weeks, while we will titrate their medication to a maintenance dose. Secondary outcome is to increase quality of life, exercise tolerance and decrease their symptom scores as noted on their questionnaires.

Etiology of heart failure in Group 1 or Group 2
Moderate heart failure as evidenced by ventricular shortening fraction <= standard deviations below the mean, or ejection fraction <= 40% d) documented shortening fraction or ejection fraction that meet criteria for greater than 3 months
