Effect of Text Messaging on Risk Factor Management in Patients With Coronary Heart Disease
Why the study?
Mobile health technologies have the potential to promote patient engagement and behavior change, but whether a culturally sensitive text messaging intervention improves risk factor control in patients with coronary heart disease in China was untested.
Does a text messaging intervention reduce systolic blood pressure in patients with coronary heart disease?
Population
822 patients with coronary heart disease and without diabetes mellitus from 37 hospitals in China
Comparison
6 text messages per week vs 2 thank you messages per month
Design
Multicenter, single-blinded randomized controlled trial
Follow-up
6 months

Implication
Text messaging did not improve BP control in this CHD cohort; leaves open optimal mHealth delivery for secondary prevention.
Structured PICO

P
Population
822 patients with coronary heart disease and without diabetes mellitus, mean age 56.4 (SD 9.5) years, 14.1% women, from 37 hospitals in China.
I
Intervention
6 text messages/week for 6 months delivered by an automated computerized system (providing educational and motivational information related to disease-specific knowledge, risk factor control, physical activity, and medication adherence) in addition to usual care.
C
Comparator
2 thank you messages/month in addition to usual care.
O
Outcome
Change in systolic blood pressure from baseline to 6 months.surrogate
A 6-month text messaging intervention providing educational and motivational information did not significantly reduce systolic blood pressure in patients with coronary heart disease.
