TUESDAY, March 27 (HealthDay News) -- An herbal preparation
derived from tree leaves offered some benefits to patients being
treated for
But at least one U.S. heart expert said the substance needs far more study before it can be deemed of any value to patients.
The substance, dubbed Crataegus Extract WS 1442, is an extract of the leaves of the Crataegus, or hawthorne, tree, and is a natural antioxidant. It's currently approved for use in some European countries as a treatment for early congestive heart failure, which is the heart's inability to adequately pump blood throughout the body.
"This is the first
In the trial, called the SPICE study and conducted at 156 centers in Europe, Holubarsch and his colleagues randomly assigned 2,681 patients with advanced congestive heart failure to receive either WS 1442 or a placebo for two years. All the patients were already receiving medications for heart failure.
The researchers wanted to see if WS 1442 could extend the time
to a first cardiac event, including sudden cardiac death, death due
to progressive heart failure, fatal
The researchers found that for patients taking WS 1442, there was a 20 percent reduction in cardiac-related death. The lives of these patients were extended by four months in the first 18 months of the study. But after two years, about the same number of people in both groups had died. This was a secondary endpoint, Holubarsch said.
However, WS 1442 was not effective when it came to death due to
progressive heart failure, fatal
