AI voice agents helped older adults with high blood pressure provide accurate readings from home, according to new research presented at the American Heart Association's Hypertension Scientific Sessions 2025.

The study involved 2,000 patients, most aged 65 or older, who received automated phone calls in multiple languages prompting them to submit readings. Calls outside safe thresholds or involving symptoms such as chest pain were immediately escalated to clinicians.

Researchers reported improved compliance and accuracy, with 68% of patients meeting blood pressure control standards. The programme also cut costs by nearly 89% compared to nurse-led interventions while boosting Medicare performance ratings.

Patient satisfaction was high, with average scores above nine out of ten. Experts said such AI tools could help close care gaps, particularly for patients with limited access to medical professionals.
