Researchers found that people with high voice biomarker scores were 2.
"Telemedicine is non-invasive, cost-effective, and increasingly important during the pandemic," said Jaskanwal Deep Singh Sara, MD, a Mayo Clinic cardiology fellow and lead author of the study
This study is the first to use speech analysis to predict CAD outcomes in prospectively followed patients after initial screening
For the new study, researchers recruited 108 patients who were referred for coronary angiography, an X-ray imaging procedure used to assess the condition of the arteries in the heart
Vocalis Health algorithms then analyze the participants' voice samples
"We don't hear these particular characteristics ourselves," Sarah said
Study participants were followed for two years
Scientists haven't concluded why certain vocal signatures seem to indicate CAD, but Sarah says the autonomic nervous system may play a role
The study was conducted with English speakers in the American Midwest, using software trained on sound samples collected in Israel
"It's definitely an exciting field, but there's still a lot of work to do," Sala said
