Using a Mobile App-Based Telecare System to Improve Blood Pressure Control in Adults with Uncontrolled Hypertension in China and Argentina

What this Trial Is About

Researchers are investigating whether a new management strategy for hypertension that combines usual care visits with the use of the ESH CARE App improves blood pressure control and related health outcomes compared to standard care. This one-year, randomized study aims to assess differences in office, home, and ambulatory blood pressure control, as well as cardiovascular and kidney-related measures in patients with uncontrolled hypertension. Participants are randomly assigned to one of two groups the usual care group, which receives standard three-monthly visits with therapy adjusted based on office blood pressure, and the POST-strategy group, which adds use of the ESH CARE App to communicate home blood pressure readings to a referral center. In the POST group, therapy adjustments occur every 15 days based on home measurements. Both groups undergo regular visits at baseline, three, six, and twelve months with clinical assessments, blood tests, urine tests, echocardiograms, ECGs, and ambulatory blood pressure monitoring. Throughout the study, participants measure home blood pressure regularly, with the POST group measuring twice weekly plus seven consecutive days before visits, and the usual care group measuring before baseline and study end. Researchers monitor blood pressure changes, heart structure, kidney function, and medication use to evaluate the effects of each strategy. The total participation lasts about one year, with detailed clinical and laboratory evaluations at scheduled intervals to assess treatment impact and safety.
