The Customer Stories Behind Eko's 750,000 Milestone
Every one of the 750,000 Eko stethoscopes sold to date has a story behind it. Some of those stories play out one exam at a time, in the hands of individual providers. Others play out at scale inside health systems that have built Eko into how they care for patients every day.
What ties them together is the same decision: leaving a 200-year-old analog tool behind for one they trust to do more for their patients.
Hitting 750,000 devices sold is a milestone we're proud of, but the number itself isn't what matters most. It's the Eko community: the clinicians, educators, and caregivers who've made that switch and now rely on Eko's devices, software, and AI algorithms — together spanning 9 FDA clearances and validated in more than 70 peer-reviewed studies — to perform with the same trusted consistency everywhere they need it, in primary care, telehealth, emergency response, education, and beyond.
A recent study published in The Lancet found that exams with Eko's AI-enabled stethoscopes increased detection of heart failure by 2.3x, atrial fibrillation by 3.5x, and valvular heart disease by 1.9x versus standard practice. That kind of performance is possible because Eko's AI has been trained and refined against millions of real-world heart sound recordings — but numbers like that only matter because of what they mean for the people using them, and the patients in their care.
To celebrate 750,000 devices sold, we're spotlighting a few of the providers and organizations who made that switch, and why they've trusted Eko with their patients' care ever since.
Scaling earlier detection across a health system
At NCH Healthcare System in Naples, Florida, primary care providers integrated Eko's AI-powered SENSORA® platform across their clinics to catch structural heart disease before it became an emergency. In 18 months, they ran more than 3,300 AI-assisted exams — nearly 1 in 4 came back positive, tripling echocardiogram referrals and confirming heart disease in 84% of patients who followed up, all without a single patient leaving primary care.

Bringing ICU-level care to wherever the helicopter lands
After nearly a decade in a busy hospital's medical and trauma ICU, Jesse Salinas became a travel nurse, trading a resource-rich city hospital for the unpredictable, often under-resourced settings of rural America, sometimes flying into places without a doctor on site. He relies on his Eko stethoscope to deliver that same ICU-level care in the air, including one flight where it helped him accurately assess a patient with multiple gunshot wounds and insert chest tubes mid-transport.

Finding her purpose, then passing it on
Before she was a pediatric nurse, Elizabeth "Lizzie" Legarski studied interior design and then transitioned to exercise science, where an internship in cardiac rehab introduced her to nursing. Now as a nurse educator, she uses Eko's hands-free technology to let a whole room of students listen in on the same heart sound at once, turning doubt into clinical confidence that comes from hearing it for themselves.

Capturing final heartbeats as keepsakes for grieving families
For hospice music therapist Anysia Palmer, an Eko stethoscope isn't a diagnostic tool — it's an instrument of remembrance. She and her team use it to record patients' heartbeats in their final moments, weaving the sounds into "sunset songs" that families can cherish long after their loved one has passed. One daughter, living far from her dying father, called the recording "the best gift" — like getting a hug from him from far away.

A career built on connection
Nurse practitioner Jolene Cannady traces her calling back to her teenage years, when she volunteered at her local hospital and spent hours listening to patients' stories. Nearly 30 years into her career, her patients know her as "Dr. Sunshine" for the warmth she brings to every visit. She uses her Eko CORE 500™ to build on that connection, letting patients see and hear their own heartbeat.

Incorporating the physical exam into virtual care
Rural patients in western Michigan used to face three-hour drives for specialty care — a brutal ask for anyone managing cancer or a chronic condition. Corewell Health integrated Eko's remote auscultation into its telehealth program, letting providers listen to heart and lung sounds and visualize waveforms in real time, even from hundreds of miles away.

Taking care of those who took care of us
Dr. Misty Zelk spent 23 years in the military reserves, rising to Colonel and deploying to Iraq, before she ever picked up a stethoscope. Today, as medical director for the Best Defense Foundation, she uses her Eko CORE 500™ to care for WWII veterans on trips back to their old battlefields, including one moment on a bus in Normandy when its noise cancellation and ECG helped her examine and stabilize a veteran experiencing chest pain.

Everyday primary care. Education. Health system implementation. Flight medicine. Telehealth. Veteran care. However our community puts an Eko stethoscope to use, the goal stays the same: help clinicians detect heart disease earlier, so patients get better treatment and better outcomes.
That goal reaches from the individual clinicians profiled here to leading academic medical centers and health systems nationwide, including Mayo Clinic and many others. 750,000 devices in, Eko is making a difference thanks to the providers and organizations who show up and listen closely every day.
