Brief summary
The COCOA-BP Trial is designed to assess the impact of 50g daily dark chocolate intake on blood pressure and compare outcome data derived from wearable/digital health devices to data derived from standard methods. Additionally, the usability of the wearable technology will be evaluated.
Detailed description
The COCOA-BP Trial is a prospective, single-center, single-arm, Boston Scientific volunteer trial, designed to assess the impact of 50g daily dark chocolate intake on blood pressure and compare outcome data derived from wearable/digital health devices to data derived from standard methods. Additionally, the usability of the wearable technology will be evaluated.
Interventions
50g dark chocolate consumed for a period of 2 weeks
Up to three wearable devices will be worn by the subject to measure parameters such as heart rate, blood pressure and number of steps
