United States: CAD screening unnecessary for asymptomatic diabetics
Routine screening for coronary artery disease in type 2 diabetes patients with no symptoms of angina or a history of heart disease is unnecessary and may lead to more invasive and costly heart procedures like cardiac catheterization, stents, or bypass, new findings indicate. With each test costing about US$1000, "Routine screening would have tremendous economic implications and our findings did not indicate that routine stress testing had additional benefit in this population," Dr. Lawrence Young, one of the researchers, was quoted as saying. These patients can generally be managed effectively with preventive therapies such as lipid-lowering drugs, blood pressure medication, aspirin, and diabetes treatment, according to Dr. Young.
