Statin Reduces Disease and Deaths from Newly
Discovered Protein Cause of Cardiovascular Problems
International clinical trial halted to rush
beneficial information to medical community
Nov. 9, 2008
The good news is that a massive clinical trial has been so
successful in reducing deaths and cardiovascular disease that it has
ended abruptly to rush the beneficial information to the medical
community. The bad news is that the international research team found a high level of
particular protein puts patients at increased risk of developing
cardiovascular disease, but this risk is drastically reduced by taking a statin drug.
The researchers with the international JUPITER
Project demonstrated that high levels of high-sensitivity C-reactive
protein (hs-CRP) leads to increased risk of cardiovascular disease. But,
this risk decreases by up to 44%, if the patients are treated with
statin medications.
"The risk of cardiovascular disease due to
increased hs-CRP levels has been greatly underestimated until now,"
according to Dr. Jacques Genest, of the Research Institute of the McGill
University Health Centre (MUHC) and McGill University Faculty of
Medicine.
"Our results show that this is an extremely
important indicator that doctors will have to consider in the future."
Dr. Genest, led the Canadian component of the
JUPITER clinical study, which was initiated by Dr. Paul Ridker of the
Harvard University Faculty of Medicine.
"We hope that this study will prompt a review of
current clinical practices, especially in terms of screening and
prevention in adults," he added. "However, we still need to do more
research to establish specific standards."

Nov.
10, 2008 - Heart failure is reaching epidemic levels among
seniors in the United States, according to research presented at
the American Heart Associations Scientific Sessions 2008. Among
the three major forms of cardiovascular disease (coronary heart
disease and stroke being the other two), only heart failure has
shown a significant increase in hospitalization rates.

The JUPITER study included 17,802 patients from 27
different countries. All had normal levels of cholesterol (LDL-c) and
high levels of hs-CRP, and according to current standards, were not
considered "at risk" for cardiovascular events, and were therefore not
receiving any treatment.
During the study, participants received a daily
dose of the statin drug rosuvastin, and its consequences were striking:
a 44% decrease in the risk of cardiovascular disease and a 21% decrease
in mortality.
"These results definitely surpassed our
predictions," said Dr. Genest.
"We had to stop the study before its scheduled
completion, as the benefit of the treatment for the selected patients
was so great that we needed to present our findings to the medical
community as soon as possible."
Since statins have a cholesterol-lowering effect,
they are currently used to prevent cardiovascular disease in patients
who are at-risk due to high LDL-c levels. But cardiovascular disease is
also caused by vascular inflammation, which is marked by levels of hs-CRP.
This study shows that statins indeed act on both cholesterol and
inflammation, an effect that has long been suspected but not proven.
