A recent study has raised concerns about using stents to treat heart disease. It suggests doctors in many cases implant stents to unblock arteries when medication and lifestyle changes would produce the same result.
, a cardiologist with Baylor Scott White Hospital in Fort Worth, explained how the results could help patients.
She says in an emergency situation 鈥� an acute heart attack, a milder heart attack or an impending heart attack 鈥� where patients are treated in the hospital, doctors typically choose to use .
鈥淲e鈥檙e looking at revascularization, meaning if there is a blockage that鈥檚 the culprit for the heart attack, we need to open it up,鈥� Farah said. "In patients who are completely asymptomatic, we can take the route of choosing medical therapy."
The new involved more than 5,000 patients who had ranging from moderate to severe. After a stress test indicated heart disease, the patients were randomly assigned to receive either medical therapy and lifestyle counseling alone, or medicine plus stents or bypass surgery.
"There is a misconception, I believe, out there that if (patients) have a positive stress test 鈥� meaning an abnormal stress test 鈥� and we don't go in there and put a stent in, they're at risk of having a heart attack," Farah said. "That's the fundamental clarification we need and this study provides that."
There are steps people can take to avoid heart disease altogether.
"There are some things that are in our control and some things that are not," Farah said. "But we have data that shows that 80% of heart disease is preventable."
She recommends people don't smoke, eat a heart-healthy diet, exercise, reduce stress, monitor their blood pressure and consult with a doctor if their blood pressure is high.
