Symptomless Heart
Disease Common Among Diabetics
posted September 07, 2004
More than one fifth of patients with
type 2 diabetes have decreased blood flow to the heart, but no symptoms to
suggest there is a problem.
Known as myocardial ischemia, this serious condition occurs when the heart does
not receive enough blood to meet its metabolic needs, usually due to plaque
build-up in the coronary arteries. When no symptoms are present, the disease is
said to be "silent."
Dr. Frans J. Th. Wackers from Yale University School of Medicine, New Haven,
Connecticut stated that, "The patients recruited for the Detection of Ischemia
in Asymptomatic Diabetics (DIAD) study were selected in such a way that there
was not even the slightest suggestion" of the presence of heart disease. "Yet we
found that even in these patients with no symptoms, 22 percent" had myocardial
ischemia.
In the DIAD study, Wackers and colleagues analyzed data from 522 patients with
type 2 diabetes.
Of the patients with silent myocardia ischemia, only 60 percent met American
Diabetes Association guidelines for heart disease screening, the investigators
report.
"I suspect that in the real world, the (rate) of silent ischemia is even
higher," Wackers said. "Our study shows again that diabetes is a very serious
risk factor for" heart disease.
Wackers added that the American Diabetes Association should revisit their
guidelines for heart disease screening in type 2 diabetics. "They obviously miss
almost half the patients with silent" disease, he said.
