Restenosis after angioplasty is essentially due to intimal hyperplasia. Low-molecular-weight heparins (LMWHs) have experimentally been shown to have antiproliferative effects in addition to their antithrombotic properties. Their potential in reducing restenosis remains to be established. Therefore, we wanted to test the hypothesis that LMWH plus aspirin is more effective than ...
