Anticoagulant-related hemorrhage in acute cerebral embolism.

abstract：BACKGROUND AND PURPOSE:Although the efficacy of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in reducing future vascular events for patients with coronary heart disease is established, less is known about the precise benefit of these agents among patients with stroke. We evaluated whether ...
