Balance of Symptomatic Pulmonary Embolism and Symptomatic Intracerebral Hemorrhage with Low-dose Anticoagulation in Recent Ischemic Stroke: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Prophylactic/low-dose heparin increased sICH by more than they reduced sPE in patients with recent ischemic stroke. Therefore, their routine acute use cannot be recommended, but they may still be relevant in patients at very high risk of PE (eg, morbid obesity, previous venous thromboembolism, and inherited thrombophilia) or if started later, although trials have not assessed these issues.
