Study design: A randomized controlled trial will be used, where patients will be randomized (1:1) to either the control group receiving usual care or the intervention group in which patients will receive usual care in combination with the TIMELY intervention for a duration of 6 months. Study sample: Female and male patients aged 18 years or over, with documented stable CAD and referred for cardiac rehabilitation (at \> 2 weeks but \<10 weeks after PCI or \>4 weeks but \<12 weeks after CABG or MI: STEM or non-STEMI), and/or having documented CAD by coronary angiography (stenosis in a major coronary artery \>50%). Intervention: Patients randomized to the intervention group will receive the TIMELY app on their phones or tablets for 6 months. Patients will also receive a wearable activity tracker that collects activity levels, heart rate and sleep characteristics. Based on patient's activity levels, self-reported momentary mental states, health-related behaviors and environmental and clinical background factors, the app will enable patient-tailored recommendations relevant to improving lifestyle behaviors during daily life. In addition, patients will receive a blood pressure monitor that measures hemodynamic parameters through pulse wave analysis and an easy-to-use ECG device which will be used to assess changes in heart rate and other cardiovascular measures at rest and with exercise. Main study parameters/endpoints: The primary biomedical outcome is a change in the CoroPredict biomarker risk score from baseline (pre-randomization) to completion of the active intervention phase (6 months). The CoroPredict score is an indicator of the 10-year risk of mortality. The primary behavioral outcome is the change from baseline to 6 months in patients' functional status of fitness level (measured using the 6-minute walk test). The study further aims to improve secondary outcome measures: physical activity levels during daily life and cardiovascular responses to exercise, dietary habits, smoking behavior, medication adherence and perceived levels of psychological stress.
