Heparin-coated versus uncoated Palmaz-Schatz stent in native coronary circulation. A randomized study with blind angioscopic assessment.

Unlabelled: The increasing use of stenting to treat more complex lesions and highly thrombogenic situations still carries higher risk for subacute stent thrombosis. To assess new heparin-coated stents in a more stringent reality, 40 consecutive patients were randomized in 1:1 ratio to receive either heparin-coated (group 1, 25 stents) or uncoated Palmaz-Schatz stents (group 2, 32 stents). The two groups were similar in baseline clinical, pre-and post-procedural angiographic and angioscopic characteristics.
