Clinical Trial Summary

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

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).

Primary	Change in cardiovascular risk factor score blood pressure	For the risk factor blood pressure 0 to 2 points will be awarded. 2 points will be rewarded if the patient reaches the goals according to ESC (European Society of Cardiology) -Guidelines where applicable, 1 point if the patient reaches the goal partially and 0 if the patient does not reach the goal.; Goals according to ESC Guidelines: Systolic 120-130 mmHg (18-69y.) Systolic < 140 mmHg (70y.) Diastolic < 80 mmHg (all ages); Points according to goals: 2 = age related SBP (systolic blood pressure) & DBP (diastolic blood pressure) goals; 1 = < 140 mmHg, > 130 mmHg 18-69yr. or < 140 mmHg and > 90 mmHg DBP >70yr 0 = SBP > 140 mmHg	at baseline and after 3 month
Primary	Change in cardiovascular risk factor score LDL	For the risk factor LDL 0 to 2 points will be awarded. 2 points will be rewarded if the patient reaches the goals according to ESC-Guidelines where applicable, 1 point if the patient reaches the goal partially and 0 if the patient does not reach the goal.; Goals according to ESC Guidelines: LDL <1.4 mmol/l and 50% reduction from baseline; Points according to goals: 2 = < 1.4 mmol/l; 1 = < 1.8 mmol/l 0 = > 1.8 mmol/l	at baseline and after 3 month
Primary	Change in cardiovascular risk factor score HbA1c	For the risk factor HbA1c 0 to 2 points will be awarded. 2 points will be rewarded if the patient reaches the goals according to ESC-Guidelines where applicable, 1 point if the patient reaches the goal partially and 0 if the patient does not reach the goal.; Goals according to ESC Guidelines: DM (diabetes mellitus) HbA1c < 7.0% or < 6.5% in recent diagnosis No DM < 5.7% (cut-off prediabetes); Points according to goals: 2 = < 5.7 %; 1 = 5.7 - 6.5 % 0 = > 6.5 %	at baseline and after 3 month
Primary	Change in cardiovascular risk factor score BMI	For the risk factor BMI 0 to 2 points will be awarded. 2 points will be rewarded if the patient reaches the goals according to ESC-Guidelines where applicable, 1 point if the patient reaches the goal partially and 0 if the patient does not reach the goal.; Goals according to ESC Guidelines: BMI 20-25 kg/m2 AC (Abdominal circumference) < 102 (men) < 88 (women) WHR (waist to hip ratio) 0.75-0.9 men & 0.70-0.85 women; Points according to goals: 2 = BMI and AC in range; 1 = only BMI or AC in range 0 = nothing in range	at baseline and after 3 month
