Effect of Home Blood Pressure Monitoring on Blood Pressure Control in Post Ischemic Stroke Older Adults

Hypertension is a major modifiable risk factor for recurrent stroke in Thailand. This study examined whether home blood pressure monitoring (HBPM) improved short-term blood pressure (BP) control after ischemic stroke. A non-equivalent control group quasi-experimental study was conducted at Phrachomklao Hospital, Thailand. Sequential allocation assigned 130 older adults to standard care and 130 to standard care plus HBPM. The primary outcome was BP control 1 week after discharge based on national guidelines. Multiple logistic regression adjusted for demographic and clinical factors. Of 260 participants, 215 completed the study (HBPM, n = 114; control, n = 101). After adjustment, the HBPM group had significantly greater odds of achieving BP control than the control group (OR = 22.656, 95% CI [9.494-54.066], p < .001). Smoking, diabetes, and lower discharge systolic BP were also associated with BP control, although these findings should be interpreted cautiously. HBPM was associated with improved short-term BP control in older adults following ischemic stroke. HBPM may be a useful addition to post-discharge care, but the single-center design and short follow-up limit generalizability. Further research should examine long-term effects and stroke recurrence.
