Many patients with severe but stable heart disease who routinely undergo invasive procedures to clear and prop open clogged arteries would do as well by just taking medications and making lifestyle changes, U.S. researchers reported on Saturday. The $100 million government-backed study, presented at the American Heart Association (AHA) meeting in Philadelphia, is the largest yet to look at whether procedures to restore normal blood flow in patients with stable heart disease offers an added benefit over more conservative treatment with aspirin, cholesterol-lowering drugs and other measures. At least two prior studies determined that artery-clearing and stenting or bypass surgery in addition to medical treatment does not significantly lower the risk of heart attacks or death compared with non-invasive medical approaches alone.
