February 25, 2022 – Dignity Health in Arizona is launching the first research study in North America in which genetic testing is used to identify men and women at risk of developing  heart disease based on the makeup of their DNA. If proven effective in clinical trials, this form of genetic testing may be adopted globally to prevent heart disease. Heart disease is the No. 1 killer in the world – in fact, half of Americans are expected to have at least one cardiac event in their lifetime. Â
