TORRANCE, CA (July 2, 2008) - Measuring calcium deposits in the heart's arteries
can help predict overall death risk in American adults, even when they are
elderly, according to a new study published in the July issue of Journal of the
American College of Cardiology.
Matthew J. Budoff, M.D., one of the study's authors and a researcher at the Los
Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed),
said previous studies had found measuring coronary arterial calcium with
computed tomography (CT) heart scans could predict overall death risks in most
American adults.
He said the latest study is the first extensive examination of coronary arterial
scans of the elderly.
"This study indicates calcium scans can be the best predictor currently
available to detect who is likely to suffer a heart attack and who is not," said
Dr. Budoff. "Previous studies found coronary arterial calcium scans were
effective tools for determining the overall death risk in young adults,
diabetics, smokers and those suffering from renal failure. This study indicates
coronary arterial scans are effective in measuring overall death risk in the
elderly."
A calcium scan looks for calcification – or a hardening of the arteries caused
by high blood fats and calcium deposits – in the arteries leading to and from
the heart. These calcifications can block blood vessels and cause heart attacks,
strokes or other health issues.
Researchers studied 35,383 adults, aged 40 to 80, in Torrance, CA and Nashville,
TN, for an average of 5.8 years after having a coronary artery calcium scan.
Among these research volunteers, 3,570 were age 70 or older.
In total, 838 deaths were recorded, 320 in women and 518 in men. The study found
the overall death risk was higher among those with higher coronary arterial
calcium scores.
"This study provides additional validation of coronary calcium studies," said
Dr. Budoff. "Coronary arterial calcium scans can be very useful tools in
assessing a patient's overall death risk. With this information, physicians can
advise patients on diet, medications, exercise and other lifestyle changes that
will help them avoid the risk of heart attack, strokes and other health
problems."
