Most practitioners use concomitant heparinization. Full heparinization was commonly used in conjunction with uPA, whereas the current trend is to administer subtherapeutic heparin with tPA. Low-molecular-weight heparin (LMWH) has not been studied in this setting.

In the coronary literature, enoxaparin improved outcomes (death and myocardial infarction reduced from 12% to 9.9%), but it significantly increased bleeding complications (from 1.4% to 2.1%).
