PLANO, Texas--(BUSINESS WIRE)--New screening tests that were largely
unavailable five years ago, can quickly and painlessly detect potential heart
problems well before they become life-threatening, according to Legacy Heart
Center managing partner Marc S. Shalek, M.D.
“And with this month being Heart Month, it’s a good time for forty-something men
and women to call their doctors and schedule a heart health check-up,” he noted.
According to statistics from the American Heart Association, although heart
disease continues to be the leading cause of death for Americans (with stroke
coming in third), the trend lines for both diseases are heading down.
Dr. Shalek attributes the decline to early detection and treatment and notes
that two new tests are particularly effective in catching cardiovascular
problems early, before damage is done.
One is called the CIMT or carotid intima media thickness test. A CIMT uses an
ultrasound scan of the carotid arteries in the neck that carry blood to the
brain to measure the thickness of the various layers in the blood vessel and the
build up of plaque.
“It actually provides an analysis of the ‘age’ of your arteries and reliably
correlates with the risk of future strokes and heart attacks. By measuring the
thickness of the first two layers of the carotid artery, we can get a good idea
of a patient’s risk for cardiovascular disease,” he noted.
The other test is a coronary calcium scoring test, which uses the new super-fast
CT scanners to measure the calcium build-up in your coronary arteries.
“Studies have shown that coronary calcium scores directly correlate with the
risk of heart attack, even if your other risk factors—family history, age,
cholesterol levels, diabetes, smoking and obesity—are low,” said Dr. Shalek.
“Although calcium doesn’t cause a heart attack, even in otherwise healthy people
a higher coronary calcium score signals that plaque is present and
atherosclerosis or hardening of the arteries has begun. Left untreated, the
arteries will gradually narrow, restricting the flow of blood and increasing
your risk of heart attack and stroke.”
Cardiologists recommend that men over 40 and women over 45 who have two or more
risk factors undergo the tests. Risk factors include high cholesterol, high
triglycerides, smoking, hypertension, diabetes, being overweight or a having a
history of heart disease in the family.
“People should keep in mind that nearly half of all heart attacks occur before
the age of 65 and more than a third of all Americans who have a heart attack
show no symptoms beforehand,” Dr. Shalek said. “On the other hand, the American
Heart Association says that some 85 percent of sudden heart attacks could be
prevented if the conditions that led to the attack are diagnosed early enough to
prescribe treatment.”
