Study: Low-income people have heightened risk of death from heart attack in six health systems around the world

Despite vastly different health care systems, low-income patients across six different countries have mortality rates 10 to 20 percent greater than their high-income peers, according to a new study led by researchers from Harvard Medical School, the University of Texas Medical Branch, Galveston, ICES (formerly the Institute for Clinical Evaluative Sciences), and other international collaborators.
