Threat women face from vascular disease not widely understood

Though arterial vascular disease is widespread and often deadly among older American women, doctors too often fail to spot and treat it, according to a new report by a team of vascular surgeons from the Columbia University Medical Center and Weill Cornell Medical College campuses of NewYork-Presbyterian Hospital.
