December 10,
2004 - The December issue of TODAY IN CARDIOLOGY provides an excellent
overview of current recommendations for coronary artery calcium scoring.
With respect to former President Clinton's
recent bypass, the article states:
"Some cardiologists
believe that an electron-beam tomography imaging study five to 10
years ago identifying advanced (or even above average for his age)
coronary artery calcifications (CAC) would have provided much-needed
information to risk-stratify and better treat Clinton, possibly avoiding
the need for surgical revascularization."
The article also notes:
"Multiple studies have examined the prognostic
accuracy of CAC measured by EBCT. Combined, these studies have included
over 25,000 asymptomatic patients followed for two to seven years,
and the risk of cardiovascular events in patients with elevated CAC
scores was 2.5 to 20 times higher than in those patients with low
CAC scores, even after adjusting for traditional risk factors for
CHD and, in some cases, CRP levels.
This prompted the National Cholesterol
Education Program Adult Treatment Panel III guidelines in 2002 to
conclude that 'measurement of coronary calcium is an option for advanced
risk assessment in appropriately selected persons. In persons with
multiple risk factors, high coronary calcium scores (e.g., >75th
percentile for age and sex) denote advanced coronary atherosclerosis
and provide a rationale for intensified LDL-lowering therapy."

an A to Z listing of key advances and discoveries. One of the entries
for the letter 'C' is as follows:
Coronary Calcium
One of the hardest things for heart doctors to do is predict, before
the appearance of any symptoms, which of their patients are likely
to have a heart attack. The Framingham Risk Score - which measures
such variables as age, sex, smoking history, cholesterol level, blood
pressure and diabetes - has helped doctors in the past, but it's not
perfect.
By combining the Framingham
scores with advanced heart-imaging technology, scientists have found,
physicians can significantly improve their ability to identify patients
at risk. Known as the coronary-artery calcium score, the imaging data
come from specialized CT scans of heart vessels that pick up calcium
deposits around which plaques can form."

Dateline November 27, 2004. Recent Article
in Wall Street Journal Reveals Power of LungScore for Preventing Lung
Cancer.
Researchers at Cornell Medical Center in New York
City will report early results of alarge study at the annual meeting
of the Radiological Society of North America.
In the study, called the International Early Lung
Cancer Action Project, 27,000 people at high risk for lung cancer
received CT, or computed tomography, scans, and 20,000 follow-up screenings
were performed in 1993 to 2004. More than 400 patients were diagnosed
with cancer, mostly in the early stages.
After following patients for up to 10 years
-- four years on average -- preliminary results indicate that 96%
of those patients who had the cancer removed had no recurrence. Lung
cancer is often diagnosed in late stages, when symptoms show up. As
a result, the five-year survival rate for all stages of lung cancer
combined is only 15%.

'LA Times Article Discusses Coronary Calcium Scoring and President
Clinton'
Many of the nation's top cardiologists
called Clinton's bypass surgery "the ultimate failure in preventive
medicine." By using only traditional risk factor testing, 88%
of those who have heart attacks would have been labeled low to moderate
risk by their doctors on the day before their heart attack.
Clinton's
experience demonstrates that even a former president with access to
the best medical care available can have undiagnosed heart disease.
Many doctors advocate aggressive use of preventive screening, including
a coronary calcium scan.

'Clinton Heart Disease Reveals Misconceptions about Testing'
A news
release from James Ehrlich, MD, president of the Society for Responsible
Preventive Imaging, discusses the failures associated with Mr. Clinton's
medical care: "Many of
the nation's leading cardiac imaging experts are examining the lessons
learned from President Clinton's recent heart problems".
"Coronary
disease among celebrities draws widespread media attention with interviews
from well known cardiologists and speculation about specific medical
examinations and appropriate attention to risk factors. In the matter
of Mr. Clinton, questions have arisen regarding his cholesterol management
and compliance with lipid-lowering medications, the failure of stress
testing to detect coronary disease and the astounding fact that his
initial symptom was severe and life-threatening, requiring immediate
bypass surgery.

September 21, 2004 - 'Scan
for Heart Attack Risk to Get a Boost' - as reported in the Wall Street Journal.
The American Heart Association is
preparing to release a statement that will, for the first time, endorse
use of coronary calcium scoring (HeartScore) for patients at intermediate
risk of heart disease. When compared to their prior statement on the
technology from the year 2000, the AHA now concludes that the evidence
is strongly in favor of using EBT scanners (the type of scanner in
use at the LifeScore Clinic) as the 'gold standard' for measuring
the quantity of atherosclerosis, or plaque, in the coronary arteries.

Dateline September 10, 2004 - Two new
studies show advantages of virtual colonoscopy over invasive colonoscopy.
The articles appeared in the September 7 issue of
Annals of Internal Medicine and in the September issue of Radiolology.
The Annals study discusses the significant blind spots that exist
with invasive colonoscopy. The Radiology article describes which kinds
of polyps are better seen with virtual colonoscopy. For an excellent
summary of the findings please follow this link.

Dateline September 4, 2004 - Dr. Wright
appeared on KUSI TV morning news to discuss Former President Clinton's
upcoming bypass surgery.
Dr. Wright noted that Clinton has thought for years
that he was at high risk because of his family history. He has had
yearly stress tests, and has been placed on Zocor, a cholesterol lowering
medication. Yet, he silently developed severe enough heart disease
to warrant a bypass at age 58.
He is a prime example of the importance of early
detection. HeartScore can easily identify the high risk patient years
before the neccesity for bypass surgery. By carefully tracking HeartScores,
patients know whether they have lowered their LDL cholesterol far
enought to initiate regression of plaque. Many people will need to
lower their LDL below 75 for plaque to be arrested.

Dateline September 1, 2004 - Major study
confirms importance of coronary artery calcium scoring.
An article
in the August 18, 2004 issue of the Journal of the American College
of Cardiology studied 1,195 patients to compare results of nuclear
stress testing with to the results of coronary artery calcium scoring.
Four important conclusions were reached:
1. Coronary artery calcium scoring (HeartScore)
was significantly better than standard risk factor analysis at identifying
those patients who had abnormal stress test results.
2. In those who had normal stress test results,
56% had coronary artery calcium scores over 100, indicating moderate
(100-400) or severe (>400) plaque burden in the arteries.
3. In those who had abnormal stress test results,
fully 90% had calcium scores over 100.
4. In those with very high calcium scores (>400),
only 23% of subjects without symptoms had abnormal stress test results,
and only 47% of those with symptoms of shortness of breath or chest
pain had abnormal stress test results.
This study confirms that the HeartScore is the best
single test for identifying patients with significant coronary plaque.
Stress testing and risk factor analysis, while important tools for
risk stratification and identification of narrowed arteries, do not
identify correctly many individuals with high levels of coronary plaque
who may require aggressive lifestyle and medical management to prevent
future heart attacks.

Dateline September 1, 2004 - LifeScore
Clinic scanner offers much lower radiation than scanner used in radiology
article (Radiology 2004;232:735-738) reported in the media on 8/21/04
This article reported research that exposure to
full body scans for 30 years (one a year) would increase lifetime
risk of cancer by 2%. A single scan would increase risk by 0.08%.
The study was purely theoretical, based on data from Hiroshima survivors
1.5 miles from the epicenter. No actual studies have been able to
demonstrate an increased risk from cancer. A single large dose of
radiation is always more harmful to the body than many smaller exposures.
The lead author of the article, Dr. Brenner, was quoted as saying:
"I don't think there's much of a problem in having one full-body
CT scan, but I wouldn't recommend having them on an annual basis."
The full body scan used for the article was done
with standard spiral CT scanners. The body was scanned from head to
toe. At the LifeScore Clinic, our scanner is electron beam technology,
which has 1/6 the radiation dose of standard scanners. The risks of
the diseases we are detecting are far greater (50% of Americans die
directly from cardiovascular disease, and it contributes to many other
deaths indirectly. Cancers kill another 20-25% of the population.)
than the comparatively minute and theoretical risk associated with
a scan.

Dateline June 16, 2004 - An article by
Dr. Allison and Dr. Wright has appeared in the International Journal
of Cardiology.
The article is entitled 'A Comparison of HDL and
LDL Cholesterol for Prevalent Coronary Calcification'. The article
looks at 6,093 HeartScore scans to determine the relative importance
of HDL vs. HDL cholesterol in determining the risk for plaque in the
coronary arteries. The study demonstrates that low HDL is three times
more powerful than high LDL in predicting the presence of plaque in
the coronary arteries. However, neither variable is very good to use
as a screening tool for the prediction of the presence of plaque,
and therefore as a predictor of future risk of a heart attack. Numerous
other studies have corrobarated this by showing that the extent of
plaque in the coronary arteries as measured by EBT scanning is a more
powerful predictor of future heart attacks that either coronary angiograms
or cholesterol levels.

Dateline June 16, 2004 - The LifeScore
Clinic is proud to announce it's participation in two important clinical
studies in association with UCSD School of Medicine. All of our patients
will be receiving a letter in the mail inviting them to participate
in these studes.
The first study, called ATHERO, is funded by the
American Heart Association. Participating patients will fill out a
questionnaire to determine whether any adverse cardiac events have
occured, what procedures have been done, what medications may have
been started, and what lifestyle changes may have been initiated.
The results of this study will provide us with valuable data on outcomes
as they are related to abnormal heart scans and neck scans.
The second study is called JUPITER, and is a long-term
study of the cholesterol lowering drugs known as statins. We are simply
looking for patients who may be interested in participating in this
important study, which will see whether statins lower risk in patients
with high levels of C-reactive protien, a marker in the blood for
inflammation.

5/3/04 - Dr. Michael Wright appeared on Channel 8 at 11 pm this evening
discussing women and heart disease.
The American Heart Association has launched
a vigorous effort to increase physician and patient awareness about
the differences between men and women with respect to heart disease
and stroke. Women develop the disease about 10 years later than men,
but suffer more severe consequences and have a poorer prognosis once
the disease is diagnosed.

Dateline April 27, 2004 - An article published
today in the Wall Street Journal discusses two recent medical studies
on virtual colonoscopy.
A study published in the New England Journal of
Medicine (NEJM) in December 2003 showed virtual colonoscopy to be
just as accurate as invasive colonoscopy. A study published this month
in the Journal of the American Medical Association (JAMA) found virtual
colonoscopy to be significantly less accurate.
The reason for the discrepancy is two-fold: The
NEJM study used cutting edge 3D workstations (Viatronix) while the
JAMA study used older 2D technology. The NEJM study also used radiologists
with experience reading the 3D studies, while the JAMA study used
relatively inexperienced readers.
At the LifeScore Clinic, we use the Viatronix workstation
used in the NEJM study (only 50 sites in the country have this technology),
AND Dr. Tabita Wright has read over 800 studies. At LifeScore, experience
and technology assure patients of the most accurate results possible.

Dateline April 6, 2004
- Dr. Michael Wright appeared on Channel 8 news discussing suprising
new findings about the height of Americans. Compared to Europeans,
Americans have traditionally been taller, because of better nutritional
status. But in the past 30-40 years, Americans have stopped growing
and are now shrinking. The average height of American males is 5'10".
The average height of British males is 5'11", while Danish men
average 6'.
The reason? Many Americans consume diets that are
low in protein, low in vitamins and minerals, low in fiber, high in
sugar and saturated fats. This results in poor nutritional status,
and a fall off in height, which is an excellent indicator of food
intake during pregnancy, childhood and adolescence, when factors affecting
growth are most prominent. In Europe, where public health systems
are integrated with social programs, nutritional issues are incorporated
into medical programs.

Dateline March 21, 2004
- A front page article in the Sunday Edition of the New York Times
explores at length the new thinking in cardiology, and how it challenges
traditional aggressive artery-opening strategies. In effect,
a narrowed artery is rarely the 'culprit lesion' in a heart attack.
The vessel wall becomes inflamed, and areas of normal width suddenly
burst open with dangerous plaque debris, causing an immediate clot
to form. So angioplasty and stenting have no impact on reducing risk
for a heart attack.
Dr. Wright believes that EBT scans of the heart
can identify those most at risk for a heart attack better than angiography.
This is because the so-called 'plaque burden' measured with the calcium
score is the best predictor of risk. The higher the plaque burden,
the more areas of plaque-filled artery susceptible to inflammation
and rupture. If a patient has a higher than average risk for heart
attack, aggressive lipid lowering with statins and/or other therapies
is indicated.
