Cycling, Walking, and Angioplasty
A fascinating discussion occurred at a meeting of the European Society of
Cardiology, which was held in Barcelona, Spain, during August. A number of
experts took the position that doctors should work harder at getting their
patients to exercise instead of simply ordering angioplasties for them.
on the meeting for the Associated Press, Maria Cheng quoted Dr. Rainer
Hambrecht, a German researcher whose 2004 study of heart patients found that
approximately 90 percent of those who regularly rode bicycles were clear of
heart problems a year after beginning their cycling program. In contrast, just
70 percent of patients who had angioplasties were still free of heart problems a
year later. Says Hambrecht, "It's difficult to convince people to exercise
instead of having angioplasty, but it works."
Earlier research has indicated that about a third of heart disease and cases
of stroke could be avoided if only people would walk briskly for two-and-a-half
hours per week. That would translate into 280,000 fewer deaths per year from
heart problems in the United States alone.
Currently less than 20 percent of heart patients perform the recommended
regimen of 30 minutes of moderate physical activity five days per week. The
European Society of Cardiology's spokesman Dr. Joep Perk says that two thirds of
heart patients planning to have angioplasties would probably get more benefit
from regular exercise.
In angioplasty, a small balloon is used to flatten an arterial blockage that
has reduced the heart's blood supply. The artery is then propped into an open
position by a mesh tube called a stent. Angioplasty has become a very routine
type of surgery, and doctors say it is harder to convince patients to commit to
regular exercise than to undertake the surgical procedure.
American College of Cardiology spokesman Dr. Christopher Cannon of Harvard
University told the AP, "Most patients want the quick fix. It's a lot easier to
get your artery fixed than it is to exercise every day."
However, although exercise takes longer to produce the desired results, its
outcomes are considered superior to those of angioplasty. Dr. Cannon notes that
while an angioplasty "only opens up one vessel blockage," exercise provides a
wide array of benefits. These include, but are not limited to:
Lowering blood pressure,
Discouraging the buildup of plaque in arteries,
Reducing levels of the harmful form of cholesterol,
Increasing levels of the beneficial form of cholesterol, and
Improving the body's ability to process sugars.
Dr. Hambrecht is presently conducting a new study that is expected to
strengthen his previous finding that in some patients, regular physical exercise
is more effective than surgery.
Dietary Sodium and Heart Disease
On another front in the battle against heart disease, the American Heart
Association (AHA) is renewing its efforts to persuade Americans to moderate
their salt intake.
consumption in the United States has climbed by 50 percent since the 1970s, and
cases of hypertension and heart disease have risen accordingly.
The recommended daily allowance for salt is 5 to 6 grams (or 2,000-2,400
milligrams of sodium). But Americans, on the average, consume 9 to 12 grams of
salt per day (or about 3,600-4,800 milligrams of sodium).
Processed foods account for much of the over-consumption of sodium in the
United States. One way to lessen the damage is to read food labels and choose
low-sodium products. AHA researchers estimate that if all Americans would cut 3
grams of salt out of their daily diets, there would be a quarter million fewer
new instances of heart disease and more than 200,000 fewer deaths over a ten
Going Strong at 82
member Richard Commins is an impressive role model for all who meet him,
including his personal training clients in Sacramento, California. The super-fit
82 year old former Marine and retired school teacher takes care of all the
gardening in his huge yard, regularly lifts weights, and follows a challenging
exercise routine that includes push-ups, pull-ups, elliptical machine workouts,
an emphasis on core muscles, and balance work on a trampoline. He even applied
to be a contestant on the popular show "Survivor" not long ago!
Profiled recently by both the Sacramento Bee and Modesto Bee newspapers,
Richard says, "I think I can be an inspiration to people. A lot of people look
at me and say, 'Boy, if he can do that at 82, I ought to get in shape.'" To

A Primer on Staying Healthy with Age
Writing for the Los Angeles Times, Jeannine Stein recently compiled a
good-sense listing of the ways in which physical exercise contributes to healthy
Strength training helps offset age-related muscle loss. The American
Geriatrics Society notes that maintaining stronger muscles (leg muscles, in
particular) and better balance could result in fewer falls,
is a leading cause of death in elderly populations.
Regular aerobic exercise helps slow or even reverse the stiffening of
arteries with age. Over time, a shift in the chemical composition of
arterial walls increases their rigidity. Aerobic exercise fights this
tendency and the resulting rise in blood pressure, which would otherwise
place extra stress on the heart.
Physical activity, especially aerobic exercise, combats diabetes in more
than one way. It leads muscles to use glucose from the blood for fuel,
thereby keeping blood sugar levels in check. It depresses the production of
insulin by the pancreas. And, it causes the liver to turn lactic acid, amino
acids, and fats into glucose, which further powers the muscles and helps
regulate blood sugar levels.
Exercise appears to decrease levels of C-reactive protein, which is a
marker for inflammation. Inflammation, which often worsens with age, is
undesirable because it increases the risk for heart disease and interferes
with the work of the immune system.
Exercise promotes brain health. A study published in the American
Journal of Neuroradiology in August found that older adults who performed at
least 180 minutes of aerobic activity every week for 10 consecutive years
enjoyed brain health benefits. Compared to a group of subjects who performed
less than 90 minutes of exercise per week, the more active seniors had more
small-diameter blood vessels with less twisting. Their vessel patterns were
similar to those of younger adults.

interviewed for Stein's story.
What'll Ya Have?
Dr. Steven Blair is a professor in the Arnold School of Public Health at the
University of South Carolina. Quoted by Jeannine Stein in her Los Angeles Times
article "Staying healthy with age should be a . . . Moving Experience," Dr.
Blair had this to say:
"Eat, drink and be merry and die happy -- who am I to argue if that's what
you want to do? But I've never met anyone who has said they want to spend the
last five years of their life frail, feeble and living in a nursing home. The
very best insurance that you can take out to maintain your independence and be
able to function is to be physically active."
