Key result
CVRM-Box remote monitoring linked to a ~5.5 mmHg systolic blood pressure reduction in high-risk CVD patients.
Why the study?
The study aimed to evaluate the effect of remote monitoring using the CVRM-Box on blood pressure control, weight management, medication prescriptions, and consultation frequency in primary care patients at high risk of CVD.
Does remote monitoring using connected devices improve blood pressure control, weight management, and healthcare utilization in primary care patients at high risk of cardiovascular disease?
Does remote monitoring using connected devices improve blood pressure control, weight management, and healthcare utilization in primary care patients at high risk of cardiovascular disease?
Remote monitoring in high-risk primary care patients improves home blood pressure control, weight management, and medication optimization while reducing the frequency of clinical consultations.

May support remote monitoring for BP/weight in high-risk CVD; extends observational data but leaves open need for RCTs.
Aims This study aimed to evaluate the effect of remote monitoring using the Cardiovascular Risk Management (CVRM)-Box on blood pressure control, weight management, medication prescriptions, and consultation frequency in primary care patients at high risk of cardiovascular disease (CVD). Methods and Results In this matched cohort study, patients with a >5% 10-year CVD mortality risk in primary care (2020–2024) were compared to propensity score-matched controls over 12 months. The CVRM-Box included smartphone-connected devices (blood pressure monitor, weighing scale, activity tracker) linked to general practitioner electronic health records. Compared to controls, the intervention group showed modest reductions in office-measured systolic (-1.1 mmHg [95% CI, -3.7 to -1.5]; p = 0.39) and diastolic blood pressure (-0.04 mmHg [95% CI, -1.6 to 1.5]; p = 0.96). Sensitivity analyses yielded similar results. However, CVRM-Box assessments showed reductions in systolic (-5.5 mmHg [95% CI, -7.6 to -3.3]; p < 0.001) and diastolic blood pressure (-3.8 mmHg [95% CI, -5.1 to -2.4]; p < 0.001). The intervention group also experienced greater reductions in weight (-0.9 kg [95% CI, -1.6 to -0.2]; p = 0.01) and BMI (-0.3 kg/m² [95% CI, -0.5 to -0.01]; p =0.007). Additionally, antihypertensive medication use increased (0.12 [95% CI, 0.06 to 0.23]; p = 0.04), while consultation frequency decreased (rate ratio 0.82; p = 0.002). Conclusions While office measurements showed no additional blood pressure reduction, CVRM-Box measurements demonstrated significant decreases. The intervention also improved target blood pressure achievement, promoted weight reduction, increased antihypertensive use, and reduced consultation frequency.
Hattem et al. (2026) studied this question. The CVRM-Box significantly reduced systolic blood pressure by 5.5 mmHg, decreased weight by 0.9 kg, and increased antihypertensive use in high-risk CVD patients.
