This is a research study in women to compare the outcomes of two procedures that restore blood flow to the arteries of the heart. In one procedure the blockages are ballooned and then stented with a small wire mesh tube through a small incision in the wrist or the groin. The other procedure is an open-heart operation in which healthy blood vessels from inside the chest, leg, and/or forearm are used to bypass the blockages (like a detour). Outcomes will be measured by comparing survival and improvement in quality-of-life.
