NEW ORLEANS -- If you want the best technology available to relieve blocked blood flow to the heart, the choice is a drug-eluting stent. And you are most likely to obtain the drug-eluting stent for reasons that have nothing to do with your medical condition, a new Mayo Clinic study shows. In fact, if you are a heart patient seeking care in an urban center, or a center in the northeastern United States, you are twice as likely to receive a drug-eluting stent than would a patient with the similar medical condition seeking care in a rural or Midwest hospital. >>> Discuss This Story
