Prostanoid compositions and methods for reducing dysfunction in human blood vessels, particularly, as a result of mechanical intervention in a blood vessel such as by a transluminal angioplasty procedure, or as a result of unstable anginal ischemia, including myocardial infarction. During acute myocardial infarction caused, e.g. by a clot in a coronary artery, a prostaglandin compounds and a thrombolytic agent are given intravenously and intra-arterially. The thrombolytic agent dissolves the clot and the prostaglandin compound provides cell protection, reduces spasm and rethrombosis due to its antiplatelet effects. In the case of a mechanical intervention as for example, in transluminal angioplasty procedures, the thrombolytic agent is given intravenously prior to the angioplasty procedure and the prostaglandin compound is administered intra-arterially during the angioplasty procedure. Further, and in a preferred embodiment, the prostaglandin compound is administered intravenously for a selected time period after the procedure. The combination is effective because the thrombolytic compounds do not affect platelet vessel wall interactions as do the prostaglandins.
用于减少人体血管功能障碍的
前列腺素组合物和方法,特别是由于对血管的机械干预,如通过经皮血管成形术,或由于不稳定的心血管缺血,包括心肌梗塞。在冠状动脉血栓等引起的急性心肌梗塞期间,可通过静脉注射和动脉内注射
前列腺素化合物和溶栓剂。溶栓剂能溶解血栓,而
前列腺素化合物则能保护细胞,并因其抗血小板作用而减少痉挛和再血栓形成。在机械干预的情况下,例如在腔内血管成形术过程中,溶栓剂在血管成形术前静脉注射,
前列腺素化合物在血管成形术过程中动脉内注射。此外,在一个优选的实施方案中,
前列腺素化合物在手术后的一段选定时间内静脉注射。由于溶栓化合物不会像
前列腺素那样影响血小板与血管壁的相互作用,因此这种组合是有效的。
