| 摘要 |
The present invention is based on the unexpected discoveries that hypothalamic inhibitory factor (HIF) has a positive inotropic effect in a whole organ preparation, such as an isolated perfused heart, and that HIF, to a greater extent than ouabain, dilates the coronary arteries in the isolated perfused heart as manifested in increased coronary flow in hearts treated with HIF. The present invention relates to a method for increasing coronary perfusion in a mammalian host comprising administering to the host in need thereof an effective amount of hypothalamic inhibitory factor (HIF). The invention also relates to a method for producing an increased coronary vasodilatory effect in a mammalian host comprising administering to a mammalian host in need thereof an effective amount of HIF. The method of the present invention can be used to prevent and/or treat ischemic cardiac malfunction and coronary artery restenosis.
