In patients with severe but stable heart disease, a procedure to improve blood flow may reduce chest pain but not the risk of heart attack or death.
People with severe but stable heart disease from clogged arteries may have less chest pain if they get a procedure to improve blood flow rather than just giving medicines a chance to help, but it won’t cut their risk of having a heart attack or dying over the following few years, a large federally funded study found.
For non-emergency cases, the study shows “there’s no need to rush” into invasive tests and procedures, said New York University’s Dr. Judith Hochman.There might even be harm: To doctors’ surprise, study participants who had a procedure were more likely to suffer a heart problem or die over the next year than those treated with medicines alone.
About 17 million Americans have clogged arteries that crimp the heart’s blood supply, which can cause periodic chest pain. Cheap and generic aspirin, cholesterol-lowering drugs and blood pressure medicines are known to cut the risk of a heart attack for these patients, but many doctors also recommend a procedure to improve blood flow.
All 5,179 participants had stress tests, usually done on a treadmill, that suggested blood flow was crimped. All were given lifestyle advice and medicines that improve heart health. Half also were given CT scans to rule out dangerous blockages, then continued on their medicines. After one year, 7% in the invasively treated group had one of those events versus 5% of those on medicines alone. At four years, the trend reversed — 13% of the procedures group and 15% of the medicines group had suffered a problem. Averaged across the entire study period, the rates were similar regardless of treatment.
“It’s intuitive that if you take the blockage away you’re going to do better, you’re going to feel better,” but the decision is up to the patient and doctor, she said.
