Overall , these aggregations of data provide evidence that DHIs can reduce CVD outcomes and have a positive impact on risk factors for CVD
OBJECTIVE To assess the potential benefit of digital health interventions ( DHIs ) on  cardiovascular disease ( CVD ) outcomes ( CVD events , all-cause mortality , hospitalizations ) and risk factors compared with non-DHIs .
Effect of Home Blood Pressure Telemonitoring With Self-Care Support on Uncontrolled Systolic Hypertension in Diabetics
Lowering blood pressure reduces cardiovascular risk , yet hypertension is poorly controlled in diabetic patients . In a pilot study we demonstrated that a home blood pressure telemonitoring system , which provided self-care messages on the smartphone of hypertensive diabetic patients immediately after each reading , improved blood pressure control . Messages were based on care paths defined by running averages of transmitted readings . The present study tests the system 's effectiveness in a r and omized , controlled trial in diabetic patients with uncontrolled systolic hypertension . Of 244 subjects screened for eligibility , 110 ( 45 % ) were r and omly allocated to the intervention ( n=55 ) or control ( n=55 ) group , and 105 ( 95.5 % ) completed the 1-year outcome visit . In the intention-to-treat analysis , mean daytime ambulatory systolic blood pressure , the primary end point , decreased significantly only in the intervention group by 9.1±15.6 mmHg ( SD ; P<0.0001 ) , and the mean between-group difference was 7.1±2.3 mmHg ( SE ; P<0.005 ) . Furthermore , 51 % of intervention subjects achieved the guideline recommended target of < 130/80 mmHg compared with 31 % of control subjects ( P<0.05 ) . These improvements were obtained without the use of more or different antihypertensive medications or additional clinic visits to physicians . Providing self-care support did not affect anxiety but worsened depression on the Hospital Anxiety and Depression Scale ( baseline , 4.1±3.76 ; exit , 5.2±4.30 ; P=0.014 ) . This study demonstrated that home blood pressure telemonitoring combined with automated self-care support reduced the blood pressure of diabetic patients with uncontrolled systolic hypertension  and improved hypertension control . Home blood pressure monitoring alone had no effect on blood pressure . Promoting patient self-care may have negative psychological effects
