Stents as Good as Surgery at Preventing Stroke
Less Invasive Approach Works as Well as Gold Standard
Stents Work as Well as Surgery
Each year, nearly 800,000 Americans suffer a stroke and nearly 140,000 die,
making it the third leading cause of death in the United States.
The new study, called CREST, involved 2,502 patients at more than 100 U.S.
and Canadian hospitals. About half underwent surgery and half received
In the first 30 days after the procedure, 4.1% of stent patients had a
stroke vs. 2.3% of surgery patients. But 2.3% of surgery patients had a heart
attack, compared with 1.1 %of stent patients.
Patients who suffered a heart attack reported a better quality of life after
recovery than patients who suffered a stroke, Brott says.
By 2.5 years later, 2.0% of patients who underwent stenting had died or
suffered a heart attack or stroke vs. 2.4% of surgery patients, a difference so
small it could have been due to chance.
In the European trial of 1,713 patients, 8.5% of stent patients had a
stroke, death or heart attack in the first 30 days after surgery, compared with
5.2% of the surgery group.
