Study aim
-
The Rheum palmatum effect on patients with systolic heart failure.
Recuperate patients with systolic heart failure after taking Rheum palmatum.
-
Design
-
By using random numbers table, patios are divided in two person case-control groups
All participants and researchers are blind in this study, coding of medicine and placebo are under the responsibility of a statistical adviser who is not blind.
-
Settings and conduct
-
Intervention group:Dry extract of Rheum palmatum root with a concentration of 10% relative to 100 of roots of the plant, has been standardized 250mg per capsule.the drug is given one capsule every 12 hours for 60 days to volunteer patients with heart failure who have ejection fraction equal to or less than40%(the patients refer to special clinic Zanjan university of Medical science)
Control group:Placebo in the control group contains starch corn which is provided in capsules and boxes of the same intervention group.the placebo is given one capsule every 12 hours for 60 days to volunteer patients with heart failure who have ejection fraction equal to or less than 40%(the patients refer to special clinic Zanjan university of Medical science)
All participations and researchers are blind in this study, coding of medicine and placebo are under the responsibility of a statistical adviser who isnot blind.
