At the University of California in Los Angeles, Cardiologist Albert Kattus and his team were doing a coronary bypass operation on a woman when suddenly one of the vessels began to constrict. As that happened, Kattus recalls, "we could feel that her coronary artery was tough like twine instead of soft and pliable...
That was quite a statement, considering that Carter's economic advisers have insisted for weeks that the Fed's emphasis on restraining inflation by reducing the growth in the money supply would unduly constrict the economy's expansion. Reporters turned to White House Press Secretary Jody Powell. Was the President correct in saying that he and Burns never disagreed? "That is wrong," said Powell. "There are differences."

Others, like hydralazine, are relaxers that seem to act directly on the muscle walls of the blood vessels, causing them to dilate and thus decrease pressure. Still others, such as guaneth-idine and reserpine-a drug extracted and purified from the Indian plant Rauwolfia serpentina-achieve the same effect by reducing the action of norepinephrine, the body chemical that...
