Reduction of Total Fat Intake Does Not
Significantly Reduce the Risk of Cardiovascular
Disease
Many
epidemiological studies has shown a healthy diet
to include low intake of saturated and trans
fat, cholesterol and a high intake of fruits,
vegetables and grains. A study done by Barbara
V. Howard, PhD et al from the MedStar Research
Institute in Hyattsville, MD found a dietary
intervention that reduced total fat intake and
increased intakes of vegetables, fruits and
grains did not significantly reduce the risk of
congestive Heart Disease (CHD), stroke, or
cardiovascular disease (CVD) in postmenopausal
women. The study was published in the February
8, 2006 issue of the Journal of the American
Medical Association.

In
Contrast to Oral Estrogen Therapy, Transdermal Estrogen
Therapy Does Not Increase the Risk of Venous Thromboembolism
in Postmenopausal Women Who Carry a Prothrombotic Mutation
There
are many factors that can increase the risk of venous
thromboembolism (VTE). Oral estrogen therapy is one known
factor that can increase the risk of VTE in postmenopausal
women. Celine Straczek PhD, et al from the Cardiovascular
Epidemiology Unit at INSERM in France investigated the
impact of the route of estrogen administration on the
association between a prothrombotic mutation and VTE risk.
Their findings, published in the November 29, 2005 issue of
Circulation, indicate that in contrast to oral estrogen,
transdermal estrogen does not confer additional risk on
women who carry a prothrombotic mutation.

Increased Risk of Death from Cardiac Causes and
Other Causes in Patients with Self-Reported Dyspnea
There are several
clinical variables that are used to evaluate
prognosis in known or suspected coronary artery
disease patients. Dyspnea is a common symptom that
may indicate subclinical left ventricular
dysfunction or pulmonary disorders, and may be
equivalent to the symptom of exertional angina.
Aiden Abidov, M.D., Ph.D., et al. from Cedars-Sinai
Medical Center in Los Angeles, CA studied the
incremental prognostic value of symptom categories
in predicting the risk of death in patients who
underwent myocardial-perfusion
single-photon-emission computed tomography (SPECT)
during stress and at rest. Their study, published in
the November 3, 2005 issue of The New England
Journal of Medicine shows that in a large cohort of
patients, those who self-reported dyspnea,
identified a subgroup of asymptomatic patients who
were at an increased risk of death from cardiac and
noncardiac causes. MORE...
Perioperative
Beta-Blocker Therapy is Associated With a Reduced Risk of
Mortality after Major Noncardiac Surgery -
Periopertive treatment with
beta-blockers is widely advocated to prevent post-operative
cardiovascular complications. Dr. Peter Lindenauer et al from
Baystate Medical Center in Springfield, Massachusetts conducted
a retrospective cohort study of patients 18 years of age or
older who underwent major noncardiac surgery. Patients who were
administered beta-blockers were compared to those who were not
administered beta-blockers prior to surgery. This study,
published in the July 28, 2005 issue of The New England
Journal of Medicine, shows that perioperative beta-blocker
therapy is associated with a reduced risk of
in-hospital death among high-risk, but not low-risk,
patients undergoing major noncardiac surgery. Increasing the use of beta-blockers in high-risk patients may
enhance patient safety. MORE...
