Personal Tragedy Puts AUM Founder and CEO Marie Johnson on Journey to Create a Device, Save Lives



Tech innovators and entrepreneurs enter the digital health space because they seek work with a purpose.

Marie Johnson’s purpose found her in a most tragic way.

Johnson, CEO and founder of AUM Cardiovascular, lost her husband, Rob, to a heart attack. He was 41, fit, and had just cleared a nuclear cardiology stress test.

Prior to the tragedy, Johnson, then an engineer and 3M Fellow, worked to develop a computerized stethoscope. She used her husband as the subject in her study, enabling her to collect data of his heart.

The day after the funeral, Johnson sat down and began sifting through the data. “I just knew his death was not by accident,” she said. “I knew I had to do something about this horrible condition.”

This search for answers led to a journey that took her and her young family to across the country and globe and finally at the head of a digital start-up.

Johnson used her insights, data, and talents to create the CADence System, an FDA-approved non-invasive, radiation-free, handheld tool to assess the sounds associated with heart disease.

Now, the start-up faces the challenge of convincing physicians, clinical academies, and payers that CADence offers a faster, better, and cheaper way of identifying heart disease.
