About MHI®

Minneapolis Heart Institute® was established in 1981 with a simple, yet lofty goal – to help prevent and treat the universal problem of heart disease. Today, our commitment to this goal is stronger than ever as we improve the quality for those we serve, whether here in Twin Cities, communities throughout Minnesota and Wisconsin, or around the world.

Committed to Research

Minneapolis Heart Institute® is complemented by its companion organization, the nonprofit Minneapolis Heart Institute Foundation®. Comprised of Minneapolis Heart Institute® physicians and a dedicated research and administrative staff, MHIF conducts extensive research to evaluate new methods of prevention and diagnosis, and to study innovative treatment methods and noninvasive procedures to reduce the stress and costs of cardiac care without compromising quality.
