  • Patent number: 4820732
    Abstract: A method for reducing dysfunction in angioplasty procedures and particularly, in myocardial angioplasty procedures in human beings is desired. The method involves the introduction of a selected amount of intra-arterial prostaglandin compound into an artery, such as a coronary artery, in which an angioplasty procedure is to occur. The prostaglandin compound will provide cyto-protection and provide antithrombotic effects and antiplatelet effects and antispasmatic effects. The prostaglandin compound is administered in a pharmacological amount, that is, an amount substantially greater than the prostaglandin which would be generated by a normal myocardial artery when insulated and thus, constitutes an administration substantially greater than an amount which would be administered in a replacement therapy.
