A balloon flattens plaque against the artery walls during balloon angioplasty.


A stent is permanently placed in the artery to hold it open.

You have chest pain (angina) or other
troubling symptoms, but you're not
suffering a heart attack. Your doctor
performs diagnostic tests and finds that
you have a blockage in one of the arteries
that supplies blood to your heart.
In the past, your doctor may have
suggested that you undergo an angioplasty
and stent procedure to open the blockage
and improve blood flow to your heart.
New evidence, however, suggests that
you may have another equally effective
noninvasive alternative.
Researchers studied nearly 2,300
patients with stable coronary heart
disease (CHD) -- clogged arteries
nourishing the heart -- as part of a
major clinical trial called the Clinical
Outcomes Utilizing Revascularization
and Aggressive Drug Evaluation, or
COURAGE Trial. Specifically, they
compared the outcomes of patients
treated with stenting procedures with
those who had medication therapy and
lifestyle intervention only.
Study Yields Startling Results
The researchers found that aggressive
medication therapy and lifestyle changes
were just as effective as stenting procedures
in preventing future cardiac events or
premature death in patients with stable
CHD.
"We now have evidence that taking
care of one blockage with a stent doesn't
fix the overall problem," says Mauricio
E. Melhado, MD, a cardiologist at
Wellington Regional Medical Center.
"Medication also plays an important
role because a blockage is just the tip
of the iceberg. Plaque tends to build up
in vessels throughout the body."
Stents Not for Everyone
About 1 million Americans have stent
procedures every year. Coronary
angioplasty and stents remain the
treatment of choice for heart attack
patients. But as many as four out
of 10 stent procedures performed every
year are elective procedures in patients
with stable CHD.
"Stents can cause problems," says
Dr. Melhado. "Many patients develop
scar tissue around the stents and need
additional procedures in the future. In
addition, there's a risk that the stent will
close completely if patients stop taking
aspirin before having dental or surgical
procedures."
Medical Therapy Key
This recent research suggests that a
medication regimen that includes aspirin,
anti-angina drugs and medications to
control high blood pressure and high
cholesterol can help relieve symptoms in
many patients with stable CHD. Lifestyle
changes, including smoking cessation,
losing excess weight and eating hearthealthy
foods, also may help.
"Many patients who take medications
and make lifestyle changes find that
their symptoms get better without
interventional procedures, so they don't
face the risk for complications that can
occur with stents," Dr. Melhado says.
"And these noninvasive treatments often
improve the health of blood vessels
throughout patients' bodies."
But he also notes that angioplasty and
stents may be an option for patients with
stable CHD who have blockages located in
specific areas or whose symptoms persist
after taking medications and making
lifestyle changes.
If you have symptomatic but stable
CHD, talk with your doctor about your
conditions and which treatment options
may be best for you.
