Coronary CTA offers a
low cost, non-invasive alternative to conventional angiography for evaluating
patients who are suspected of having coronary artery disease; true even if the
patients have calcified coronary artery plaques, according to a study performed
at the Thomas Jefferson University Hospital, Philadelphia, PA.
The study included 31
patients who had one or more calcified coronary artery plaques that were
discovered during coronary CTA. Calcified plaques in the arteries were graded as
small, moderate or large. Initially the accuracy rate of determining the degree
of stenosis caused by the larger calcified plaques was 67%. The study is ongoing
and “now with further experience, the accuracy rate of determining the degree of
stenosis with larger plaques is 72%,” said David C. Levin, MD, lead author of
“Patients who have
calcified plaques in their coronary arteries can be evaluated accurately using
coronary CTA. The procedure is non-invasive, cheaper and does not require
hospitalization. Using coronary CTA you can look at a patient’s arteries from an
infinite number of angles and look at cross sections of vessels. With
conventional angiography, the patient usually is admitted to the hospital and
the arteries are only visible from 7 to 10 different angles,” said Dr. Levin.
Coronary CTA is
recommended for patients with an intermediate risk of coronary artery disease.
“A good candidate is somebody who has an atypical chest pain pattern; chest pain
that comes and goes during the day, night, exercise, rest etc. Family history,
high cholesterol, diabetes, smoking and hypertension also play a big factor in
the determining risk category,” said Dr. Levin.
