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 .
Utilization of the internet to deliver cardiac rehabilitation at a distance: a pilot study.
Less than 25 % of eligible patients attend cardiac rehabilitation programs ( CRP )  , with geographical proximity being a predominant barrier . Therefore , we undertook a pilot study to assess the feasibility and safety of using the Internet as a medium for delivery of an interactive " virtual " CRP ( vCRP ) to patients at a distance . Fifteen patients on the waiting list for a local hospital-based CRP were r and omized to either an Internet-based vCRP or observational control . The vCRP consisted of on-line intake forms , one-on-one chat sessions with a nurse , dietitian , and exercise specialist , downloadable exercise heart rate monitoring , education and data monitoring of blood pressure , weight , and glucose . Participants were assessed for exercise capacity , risk factors , and lifestyle behaviors at baseline and at 12 weeks . Those in the vCRP logged onto the Internet-based CRP an average of 4.2 times per week . There were no adverse events in the vCRP participants . The vCRP group significantly improved their HDL-C , triglycerides , total cholesterol : HDL-C ratio , exercise capacity as assessed in metabolic equivalents , weekly physical activity , and exercise specific self-efficacy ( p < 0.05 ) . There were no significant improvements in the control group . Improvements in the vCRP group were similar to historical controls in a st and ard CRP . Feedback from exit interviews of the vCRP participants was unanimously positive . This Internet-based CRP result ed in clinical ly significant improvements in risk factors and exercise capacity similar to that of a st and ard CRP . The high user acceptance indicated that this program may have the potential to effectively manage patients who do not have access to traditional hospital-based CRP
