CHICAGO: 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, US researchers reported on Saturday.
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. Current guidelines recommend patients with severe narrowing of their arteries have heart bypass surgery or a stent implanted to restore blood flow. Stents are tiny tubes that keep the artery open after blockage-clearing angioplasty.
Just eliminating unnecessary stenting procedures could save the US healthcare system US$570 million annually, said Stanford University School of Medicine cardiologist and study co-chair Dr. David Maron. He estimates the cost per stenting procedure at about US$25,000 and bypass surgery at US$45,000. On these measures, the addition of stenting or bypass surgery to reroute blood flow around the arterial blockage was no better at reducing the adverse events than medical therapy alone. The invasive treatments did result in better symptom relief and quality of life in those who had frequent chest pain.
