The drugs that drug-coated stents exude prevent cells in the artery wall from covering the stent. Without this protective sheath, clots can form on the stent. Early studies suggested that this problem, known as stent thrombosis, was twice as likely to happen with drug-coated stents as with bare-metal stents. However, a long-term follow-up showed no significant difference in deaths and heart attacks among 19,000 people three years after receiving a drug-coated or bare-metal stent.
