Details and patient eligibility

About

The study aims to assess the effect of smart watches and continuous glucose measuring devices on cardiovascular risk factors.

Full description

Within a period of 4 months 100 patients will be recruited and randomised to the intervention or control arm (1:1) for a duration of 3 months. Randomisation will be stratified by age, sex, BMI, diabetes, blood pressure, and duration after finishing cardiac rehabilitation. Patients randomised to the intervention arm will be given a smart watch as well as a continuous blood glucose measurement device with detailed instructions. At baseline and at the end of the study questionnaires will be answered and anthropomorphic measurements attained. Blood samples will be drawn at baseline and after an intervention period of 3 months in all subjects. Additional data on sleep, temperature, heart rate (resting and exercise), breathing rate, activity and exercise, oxygen saturation and daily weight will be collected through the Fitbit web application programming interface (API).
