Participants in Web-based lifestyle counseling reduced their systolic blood pressure by 10 mmHg, compared with a 6 mmHg reduction for those taking part in a web-based control intervention, a statistically significant difference, according to a new study. The research from this trial — the first randomized, double-blinded trial of an online behavioral intervention for high blood pressure — was presented at the American College of Cardiology’s 66th Annual Scientific Session, March 17-19 in Washington, D.C.
