Use of vasodilators in congestive heart failure.
In order to select the proper vasodilator agent for the treatment of congestive heart failure, the underlying etiology and pathophysiology of heart failure must be understood since they are important determinants of the response to the particular vasodilator being used. Short-term studies are impressive. Most patients respond dramatically to vasodilators. Long-term studies are not available at this time. When they become available, the clinical usefulness of this group of drugs will be put in proper perspective.
