According to health records from January 2026, rural heart failure patients can utilize Abbott’s implanted CardioMEMS HERO Device to remotely monitor pulmonary artery pressures and transmit daily readings to clinical teams, significantly reducing the need for frequent, long-distance hospital visits for specialized care.
Remote Heart Monitoring for Rural Patients
Angie Lindsey, a former nursing home administrator living in a small town in Missouri, experienced a massive heart attack in 2019 that left her with congestive heart failure and chronic fluid retention. Because her condition required specialized management, she initially had to travel two and a half hours to Mercy Hospital South near St. Louis. To curb these exhausting trips, she received Abbott’s paperclip-sized pulmonary artery pressure sensor in April 2026. The outpatient procedure takes only a few hours, according to hospital records.
Pro Tip: Remote hemodynamic monitoring devices operate without batteries and can last the lifetime of the patient, functioning when the individual rests on a specialized pillow or pad each morning, according to Dr. Charles Carey.
How the CardioMEMS HERO Device Functions
The implanted sensor tracks rising pulmonary artery pressures, which signal worsening heart failure before physical symptoms become severe. Dr. Charles Carey, cardiologist and medical director of the heart failure program at Mercy South, notes that patients take a daily reading in under five minutes by lying on a radio-frequency signal pad. “Once a patient undergoes a reading, the result is sent automatically to our office,” Dr. Carey told Healthline. The incoming data allows clinicians to adjust guideline-directed medical therapy—most commonly increasing diuretics to remove extra sodium—before a crisis occurs.
Clinical Benefits and Patient Impact
For Lindsey, the technology removed the guesswork from managing a chronic illness that once caused her to gain 29 pounds of fluid in just 12 days. Days after returning home from the sensor implantation, her care team caught a rising pressure reading over the phone and adjusted her medications before she required emergency intervention. This proactive care restored her independence, allowing her to travel to the ocean, visit family, and pursue watercolor painting, which has yielded a one-woman show and local art festival exhibitions.
Frequently Asked Questions
How long does a CardioMEMS sensor last?
According to Dr. Charles Carey, the implanted pulmonary artery pressure sensor contains no battery and can last the lifetime of the patient.
How often do patients need to take readings?
Patients complete a brief, daily reading at home by resting on a radio-frequency pad, a process that takes less than five minutes.
Where is specialized heart failure care managed?
Specialized care can be coordinated remotely by clinical teams at regional medical centers, such as Mercy Hospital South in St. Louis, allowing rural patients to avoid frequent long-distance travel.
