(Ivanhoe Newswire) – New research shows screening diabetic patients for
coronary arterial disease (CAD) does not reduce the rate of coronary events.
Nearly 200 million people worldwide have type 2 diabetes, putting them at
increased risk for CAD, which can lead to a heart attack or sudden cardiac
death. CAD often shows no symptoms, leaving patients in the dark about their
risk for coronary events. However, in a recent study, researchers found routine
screening for CAD did not significantly reduce patients’ risk of a coronary
event.
Over a five year follow up period, researchers found the number of coronary
events, rates of primary medical prevention and coronary revascularization were
nearly identical, showing no benefit to routine CAD screening.
“Rather than viewing this study as a negative screening study, clinicians might
consider the results as a positive message: patients with type 2 diabetes
without symptoms to suggest CAD, receiving contemporary medical care, close
follow-up, and appropriate diagnostic evaluation for symptoms of ischemia have
relatively favorable outcomes in the current era," the study authors wrote.
