Prospective randomized comparison of early and late results of a carbonized stent versus a high-grade stainless steel stent of identical design: The Prevention of Recurrent Venous Thromboembolism (PREVENT) trial

The hypothesis of superiority of the carbonized stent over a stainless steel stent of identical design with regard to restenosis and MACE could not be proved. Inactive coating of stents seems to have no advantage over pure stainless steel stents, which was also demonstrated in other trials. The future probably lies in active coating of stents with drugs that reduce the neointimal proliferation process.
